Opis:
The research aimed to find suitable solutions to reduce the salinity stress of irrigation water for some types of vegetables in hydroponics under two drip and mist irrigation systems. The different concentrations of NaCl for irrigation water, are 500, 1000, 2000, 3000, and 4000 ppm used. Proline (30 mg∙dm -3), humic acid (300 mg∙dm -3) and compared without any from them were used to study their effect on the yield, and water use efficiency. The results indicated that the highest spinach and courgette yield (4.657 and 5.153 kg∙m -2) was observed for the DP500 treatment, and the lowest yield (0.348 and 0.634 kg∙m -2) was observed for the SW4000 treatment, respectively. The use of humic acid led to an increased yield on average by about 16.8 and 19.3% for spinach, and 39.4 and 51.7% for courgette, under drip and mist irrigation, respectively. Using proline led to an increased average yield of about 32.9 and 33% for spinach, and 51.8 and 58.4% for courgette, under drip and mist irrigation, respectively. The highest water use efficiency (WUE) of spinach and courgette (43.1 and 51.5 kg∙m -3) was observed for the DP500 treatment, and the lowest (3.2 and 6.3 kg∙m -3) was observed for the SW4000 treatment. According to our study, the use of proline and humic acid could compensate for the adverse effects of salinity under mist spraying more than drip irrigation.

Opis:
The paper describes the first attempts at the sprinkler irrigation of plants in Poland which took place in the Kujawy and Wielkopolska Region more than a hundred years ago – at the early 20th century. The first original sprinkler irrigation machine was designed and the used by Mr Władysław Szczepkowski. The sprinkler irrigation machine he constructed in 1911, after earlier a few year trials (at Łęg, the Śrem county, the Poznań Province) was the first sprinkler irrigation machine built at such a large scale in Europe. The system developed by Szczepkowski found many followers in Germany, France, England and the USA. Szczepkowski’s sprinkler irrigation machine became a prototype for many later designs, e.g. the irrigation machines applied today rolled sprinkling pipelines.

Opis:
The effect of deficit irrigation imposed in July-August period on shoot growth and flower formation in container grown rhododendron in commercial nursery were assessed. Plants were exposed to three irrigation regimes based on potential evapotranspiration rates (100% ET0 - well-watered control plants, 75% ET0 - moderate drought and 50% ET0 - severe drought). The values of evapotranspiration were calculated using the Penman-Monteith model. The degree of drought had significant effect on the plant growth and water status of plants. Severe drought inhibited secondary shoot elongation compared to less stressful regime but did not affect flower formation. ‘Catawbiense Boursault’, ‘Nova Zembla’ and ‘Pearce’s American Beauty’ plants exposed to severe drought were shorter, respectively by 39, 45 and 86% than well-irrigated plants and two of the three cultivars ‘Catawbiense Boursault’ and ‘Pearce’s American Beauty’ produced fewer secondary branches (5.9 and 0.3) compared to control plants (9.2 and 1.7, respectively). Moderate drought did not affect plant growth but resulted in flower bud formation in ‘Nova Zembla’ and ‘Pearce’s American Beauty’s cultivars. Estimated water consumption by rhododendrons throughout the whole growing season was reduced by 15% for moderate and 25% for severe drought compared to control, well-watered plants. The results have significant implications for water conserving in commercial production of rhododendrons.

Opis:
The main purpose of this study is to determine the optimum water consumption for achieving water savings and obtaining good yields in cotton production, which has been expanding in Central Asia and Turkmenistan since the 1960s. In the last few decades, water resources in the region have been difficult to access, due to the expansion of agricultural activity and population growth. The oscillation of the amount of water released from dams of the Amudarya River to obtain energy for the upper countries in the winter season has been causing crises in countries of Central Asia. An experiment was carried out in an agricultural field at a cotton research centre in the Yolöten district of Turkmenistan. The experiment led to the observation that it is possible to achieve higher efficiency and lower water consumption in cotton production. At the same time, the water savings that can be achieved as a result of using the drip irrigation method in cotton production throughout the country have been calculated. The calculations have provided the basis for recommending irrigation as a solution to the problems in question.

Opis:
The aim of soil solarization is to control soil borne pathogens and weeds heating with solar energy of soil which is sufficiently wetted. Soil water content is the one of the most important factors affecting soil solarization. Humidity level is important to convey temperature from the upper layers to down layers of soil in solarized soil. For this purpose, the study was conducted in plastic greenhouse in Isparta province. Beginning of the study, all plots were irrigated to reach the field capacity, and then the all plots were irrigated in 5 days irrigation interval during the experiment periods. Temperature distribution was measured in 5, 10, 20 and 30 cm of the soil profile along the experiment periods. As a result of this study, increasing of soil temperature and effectiveness of solarization decreased with together the water content of soil in upper layers. However, the soil temperature increased with irrigation in the down layers.

Opis:
Since the 19th century, the irrigation industry on the territory of the Czech Republic has undergone considerable technological development and an increase in irrigated areas. Irrigation has become an important part of the Czech landscape. Large complex irrigation systems of tens to hundreds of km2 have been built. Towards the end of the 20th century, there was a significant decline due to the change of political regime, abolition of agricultural companies, etc. Irrigation systems and buildings were often destroyed, devastated, left without maintenance. There have also been several changes in the administrative management of the irrigation sector. The consequence was that there was no single database of irrigation systems. At present, a database of these irrigation systems is being compiled by the Research Institute for Soil and Water Conservation using geographical information systems (GIS). In connection with climate change, the threat of drought, and irregular distribution of precipitation during the growing season, and the issue of irrigation are back on trend. In this study the current state of irrigation systems in the Czech Republic was presented. In the Czech Republic, a total of 175115 ha of irrigation area has been recorded so far (of this area, about 41% is currently in functional). Selected historic irrigation structures were documented by unmanned aerial vehicles (UAV).

Opis:
More than 4.6 mln ha in the Russian Federation are irrigated. Their culvert hydraulic structures are part of network structures and are the most widespread. After the crisis of the 1990s, proper maintenance of many reclamation systems was impossible due to a lack of funds. This led to the loss of about half of the water taken from irrigation sources in irrigation canals. The planned increase in the technical level of irrigation systems requires the automation of the operation of both the entire system as a whole and separately located culverts. This will avoid significant losses of water supply for irrigation and prevent water shortages with the insufficient discipline of water users. Means of hydraulic automation of water supply are being installed on small irrigation canals in Russia. A water flow regulating valve is proposed, with no mechanical movinparts, and gates are not involved in the control process. The operation of the structure is based on the injection effect, in which excess water entering the downstream with a decrease in water consumption begins to circulate between the outlet section of the transit pipe and the diffuser at the end section of the valve. Using the methods of measuring hydrodynamics and the theory of jet devices, theoretical dependences were obtained, which make it possible to determine the main hydraulic characteristics of the structure. The design form of the flow part of the regulator has been developed and a physical model has been made. In a mirror hydraulic flume, the operation modes of the water outlet were studied with and without regulation. The actual values of hydraulic parameters were obtained, which confirmed the validity of the use of theoretical dependencies. The discrepancy between the theoretical and experimental results is within the experimental error. It has been proven that it is possible to circulate excess water between the downstream and intermediate pools of the regulator.

The study took place between 2012 and 2014 in Falenty near Warsaw, Poland, as part of a long-term scientific experiment (first began in 1987) using the randomized block method. All blocks were irrigated until 2008. In 2009 each block was divided into two areas: irrigated and non-irrigated. The study involved four levels of inorganic nitrogen fertilizer and two levels of mixed inorganic and organic fertilizer in the form of fermented cattle urine. The soil in all experimental plots was characterized by low levels of zinc, ranging from 7.6 to 16.7 mg Zn∙kg–1 dry matter. Much lower Zn content in both soil layers of all irrigated plots was associated with increased yields on these plots, regardless of the level and form of fertilizer. The content of Zn in soil and sward in 2014 year was significantly lower compared in 2012. Inadequate levels of zinc for ruminant nutrition were observed in the sward from all plots (15.4–28.8 mg∙kg–1 dry matter). The higher content of zinc was found in sward harvested from the plot, which was not fertilized with phosphorus. The long-term inorganic and fermented urine fertilization resulted in very low zinc content in the soil and meadow sward.

To evaluate the economic efficiency of irrigation in corn cultivated for grain, production effects were used, which were obtained from studies conducted by researcher team from the Department of Land Reclamation and Agrometeorology at the Experiment Station of the UTP University of Science and Technology in Bydgoszcz in 2005-2016. The research covered the effect of irrigation on yielding of the crop. Economic efficiency calculations were made using the direct surplus increase calculation method. In each variant irrigation enhanced production effects. It was not always economically justified, however. The irrigation costs (for drip and sprinkler irrigation systems) per hectare were decreasing with an increase in acreage. Applying drip irrigation was economically unjustified in moist years and on average in the multi-year period. In the years with dry and average precipitation conditions the direct surplus was positive, except for irrigation of 1 ha. As for the sprinkler-irrigation system, a lack of economic efficiency was reported in moist years, whereas in dry and average years as well as on average in the multi-year period, except for 1 hectare acreage, corn sprinkler-irrigation was economically justified.

Three soybean varieties (Lastochka, Danaya, and Akku) were used in the study. Due to the uniform supply of water to the roots of plants, drip irrigation has a positive effect on the quantitative characteristics of growth and development of soybean plants and the formation of productivity indices, as compared to furrow irrigation. The yield of soybean varieties (an integral index that depends on the irrigation methods) increased for all varieties by 5.6–10.6 c/ha with the use of drip irrigation.

The irrigation system was im- plemented in 2010 and 2012 as an element of two development projects co-financed by Ministry of Foreign Affairs of the Republic of Poland un- der the Polish Development Programme. During the first phase ( 2010) the earth water reservoir and the canal carrying water on a meadow were built and the irrigation system based on Amirite sprinklers was installed . In 2012, the concrete water tanks were built , and two hose reel irrigators were bought and put in action . The i mplementation of the irrigation system allowed for a significant increase in the production of hay. In the analyzed time period (from 2008 to 2012) the increase in yields of hay from 34.7 tons to 237.3 tons was noticed. The resulting implementation of the irrigation project increase hay production should be considered valuable, especially under the conditions of advancing climate change and its potential impact on the reduction of agricultural production in Tanzania.

Opis:
The paper characterizes the status, trends and perspectives of irrigation in Poland after the reforms in agriculture and technology. Irrigation in Poland has supplemental character. It is used in short periods during the growing season and plays an important role in mitigating the effects of drought on crop production. Sub-irrigation from ditches is applied on permanent grasslands, sprinkling - in field cultivation of arable crops, sprinkling and drip irrigation - in vegetable growing in open areas, micro-jets and drip irrigation systems - in orchards. Drip irrigation and micro-jets systems are also applied in plant cultivation in greenhouses. Under the economic conditions of Polish agriculture irrigation is often an unprofitable measure. The existing irrigation systems and facilities are only used to a small extent. After changes in the forms of ownership in agriculture, the large-area sprinkling systems were degraded. Small irrigation systems, mainly drip irrigation and micro-sprinkler irrigation, have recently become more common in private farms. Sub-irrigation systems are largely degraded and used only to a small extent if at all. In order to use these systems more effectively, it is necessary to reconstruct and modernize them. In many cases the factor preventing the use of irrigation systems is the deficit of water of required quality and its availability. Besides unfavourable economic conditions, it is one of the main limitations in the development of irrigation in Poland.
W pracy przedstawiono obecny stan nawodnień w Polsce, jak również trendy i perspektywy nawodnień. Nawodnienia w Polsce mają charakter interwencyjny, likwidujący okresowy niedobór opadów. W dolinowych trwałych użytkach zielonych stosuje się nawodnienia podsiąkowe z systemem rowów, w uprawach polowych - deszczowanie, w warzywnictwie na otwartych polach - deszczowanie i nawodnienia kroplowe, w sadownictwie i w uprawach szklarniowych - mikrodeszczowanie i nawodnienia kroplowe. Po zmianach własnościowych w rolnictwie wielkoobszarowe deszczownie uległy znacznej lub całkowitej dewastacji. Systemy nawodnień podsiąkowych są również w znacznym stopniu zdewastowane i wykorzystywane w niewielkim stopniu. W celu zwiększenia efektywności tych systemów, należy je odbudować i zmodernizować. W ostatnich latach obserwuje się rosnącą rolę mikronawodnień w sadownictwie i w polowych uprawach warzywniczych, w prywatnych gospodarstwach rolnych nastawionych na taką produkcję, w których nawodnienia gwarantują stabilizację plonu dobrej jakości na poziomie przynoszącym zysk. Taki trend będzie się nasilał w najbliższych latach. W aktualnych warunkach ekonomicznych rolnictwa w Polsce nieopłacalne jest nawadnianie prawie wszystkich upraw polowych, z wyjątkiem ziemniaków. Opłacalne jest natomiast nawadnianie upraw warzywniczych i sadowniczych. Urządzenia i systemy nawodnień ciśnieniowych są zarządzane przez ich właścicieli, tj. rolników, grupy rolników (producenckie) lub prywatne firmy. Systemy nawodnień grawitacyjnych w zakresie melioracji szczegółowych są zarządzane przez rolników - właścicieli gruntów i urządzeń na nich się znajdujących bądź przez spółki wodne, jeśli ci rolnicy są członkami spółki. Realizują oni zadania z zakresu prowadzenia nawodnień i utrzymania urządzeń. W zarządzaniu nawodnieniami grawitacyjnymi uczestniczą jeszcze wojewódzkie zarządy melioracji i urządzeń wodnych, które są odpowiedzialne za dostarczenie wody do systemów nawodnień, jak również eksploatację i utrzymanie urządzeń melioracji podstawowych temu służącym (budowli piętrzących, budowli ujęciowych, kanałów, będących źródłem wody do nawodnień). Dalszy rozwój nawodnień w Polsce może być w znacznym stopniu ograniczony, poza niekorzystnymi uwarunkowaniami ekonomicznymi, zasobnością źródeł wody do nawodnień, a w przypadku mikronawodnień - również jakością wody. Już obecnie w regionach (np. na Kujawach), wyposażonych w urządzenia nawadniające, w suchych latach nie można prowadzić nawodnień z powodu zbyt niskich stanów wody w ciekach, jeziorach i małych zbiornikach sztucznych, będących źródłem wody do nawodnień.

Franz, conducted in the vegetation season of 2016 (dry in terms of the recorded precipitation total) on a family farm in Kobylata, the Kłodawa commune, the Wielkopolskie Province. Water requirement observed as early as April was balanced by sprinkler irrigation in seasonal application rates ranging from 75 mm (rape) to 105 mm (wheat). Sprinkling of winter rape was the factor having a highly significant effect on seed yield volume, on average from 4 plots amounting to 4.1 t·ha-1 and by 17.4% greater than the yield harvested in the non-irrigated plots (control) - of 0.6 t·ha-1. Winter wheat, at the application of sprinkler irrigation, also produced greater yields (by 24%) in comparison to the non-irrigated plots. Mean grain yield of wheat in the irrigated plots was by 1.9 t·ha-1 greater. Advisability of irrigation, apart from higher yielding, may also be indicated by water use efficiency in these crops. Every mm of sprinkled water caused an increase in of rape by 7.9 kg, while in wheat by 17.8 kg.

Opis:
The aim of the study conducted in the years 2014-2016 was to determine the effects of different irrigation systems and doses of different organic fertilizers on the yield of crisphead lettuce. The experiments were conducted in a certified organic field of the Research Institute of Horticulture in Skierniewice. The study compared micro-sprinkler irrigation, drip irrigation and the control combination (without irrigation). The fertilization combinations involved the use of compost at 30 t/ha, Ekofert L in a dose corresponding to 50 and 100 kg N/ha, Fertilan L in a dose corresponding to 50 and 100 kg N/ha, and the control (no fertilizer). It was found that the use of irrigation in the first and third year of the study did not produce positive results, which was due to sufficient rainfall that fully satisfied the water requirements of lettuce plants. However, with a total rainfall not exceeding 80 mm (in 2015), the use of the irrigation systems had a significant impact on yield. Compared with the control, the irrigation with micro-sprinklers in 2015 increased the yield of lettuce by 35%, and in the case of drip irrigation by 40%. The response of lettuce plants to the applied organic fertilization varied in the individual years of the study; however, of all the tested fertilization treatments, the use of compost at 30 t/ha produced the best yield-enhancing effect. Fertilization with the lucerne-based fertilizers resulted in an increase in yield, in relation to the control combination, in only one year of the study (2015). The results showed that the organic fertilizers Ekofert L and Fertilan L were slow-acting fertilizers because their impact on the yield of lettuce, a plant with a short vegetative period, was relatively small. These fertilizers are more effective in the cultivation of species that have a long period of vegetative growth.

Opis:
Drought is generally associated with the persistence of low precipitation amount, decreased soil moisture and water availability relative to the normal levels in a designated area. The effects of drought, range from the morphological to molecular levels, and are evident at all phenological stages of the plant growth, at whatever stage the water deficit occurs. Determination of the surface water demands for irrigation purposes comes out from the assumption of hydrologic processes stationarity. This paper shows our research prerequisite that water stress participates in an important part on the volume changes of over ground parts, which is predictive for the irrigation demand. Malus domestica var. Yellow Transparent was chosen for the measurement of volume changes of the surface plant parts. Our measurements were realised by the Diameter dendrometer small (DD-S) from 24.08. to 13.09.2017. One tree was irrigated by the dose of 50 mm. We compared the dendrometric changes to soil moisture and rainfall on both irrigated and non-irrigated trees. The experiment showed the differences between the irrigated apple tree (the diameters of the branches fluctuated between 11.9 and 12.1 mm) and the non-irrigated apple tree (the diameter of the branches increased after three-day rain from 8.35 to 8.61 mm), in order to determine the water stress of plants based on dendrometric changes and optimize irrigation during the drought period.

A field experiment was carried out in two vegetation seasons in the years 2012 and 2013 on very light soil at Kruszyn Krajeński, in the vicinity of Bydgoszcz, Poland. The aim of the study was to characterize morphological achenes and determine the fertility potential and real of cup plant (Silphium perfoliatum L.) plants derived from micropropagation grown under irrigation. Low fertility real of cap plant resulted from the participation of infertile fruit-achenes it means devoid of the seeds. Due to the fact that this plant is entered on the list of invasive species, this property may be desirable during plantation establishment. As a result, the plant will not be so easy to penetrate into the ecosystem and will not pose a threat to native biodiversity.

The paperwork includes estimate of irrigation on yield effect of highbush blueberry. The research was conducted in 2014-2016, on a small plantation located in Przyczyna Górna, in the Wschowski county, in the Lubuskie Province. The plantation’s area was 800 m2. The article presents an analysis of five varieties of highbush blueberry: Patriot, Duke, Chandler, Elliott and Bluecrop. The frequency of irrigation and the amount of water supplied to the shrubs depended mainly on the distribution of atmospheric precipitation and the optimal humidity that the soil needs in growing blueberries. The need for irrigation was determined on the basis of soil water suction measurements using tensiometers. The shrubs were irrigated with a drip line with a spacing adjusted to the spacing of blueberry bushes. The annual dose of water used for irrigation were from 144 mm to 303 mm. The research showed that the average crop increase amounted to 167%, because of irrigation. In 2015, which was a wet year, the increase was 140% and in the average year (2014) was 193%. It was not connected only with amount of precipitation, but with the distribution of precipitation at growing season. The best yield was noted for Chandler (32% of yield), Patriot and Bluecrop (20%).

The agricultural sector is currently witnessing the use of Internet of Things (IoT) to drive significant innovations across key interests, particularly irrigation. A sprinkler designed with an Arduino controller was developed in this study. The device is among the fastest growing agricultural irrigation systems. The plant studied is Brassica Chinensis, because this vegetable is one of the most commonly consumed vegetables by Indonesian people. However, emphasis is also placed on plant quality as an important consideration, not only on the device’s operational performance. The purpose of this research was to compare the plant quality, including the dissolved solids, chlorophyll, carotenoid, and vitamin C using manual and Arduino-based sprinkler. As consequence, three treatment methods were employed, termed: the use of manual sprinkle, e.g. P0, and Arduino-based IoT sprinkler, described as P1 and P2. Under these conditions, the chlorophyll quality was comparable to the results obtained using the manual application. P1 is a situation where the sprinkler is manually set by the farmer via the app. Meanwhile, P2 uses a sprinkler which is automatically regulated by the system. Under these conditions, the chlorophyll quality generated with the IoT sprinkler was comparable to the results obtained using the manual application.

Celem pracy było opracowanie innowacyjnych urządzeń służących do pomiaru i regulacji natężenia przepływu wody w systemach nawodnień podsiąkowych. Są to: zasuwa dwudzielna z przelewem prostokątnym do pomiaru i regulacji natężenia przepływu wody, zasuwa dwudzielna z przelewem trójkątnym do pomiaru i regulacji natężenia przepływu wody, zestaw przelewów do regulacji piętrzenia oraz pomiaru i regulacji przepływu wody na przepustozastawce oraz regulator piętrzenia wody w rowie. Praca powstała na podstawie wiedzy eksperckiej, studium literatury oraz wizji terenowych. Opracowane prototypowe urządzenia charakteryzują się dużą funkcjonalnością, gdyż mogą być instalowane na istniejących piętrzących budowlach melioracyjnych oraz służą nie tylko do pomiaru i regulacji natężenia przepływu wody, lecz również do regulacji piętrzenia wody w rowach odwadniająco-nawadniających na trwałych użytkach zielonych. Zainstalowane na obiektach nawodnień podsiąkowych prototypy będą badane pod kątem dokładności i zakresu prowadzonego pomiaru oraz ich użyteczności w warunkach odwodnień i nawodnień poprzez regulację położenia wody w rowach melioracyjnych.
The aim of the work was to develop innovative devices for measuring and regulating flow rate in irrigation systems. These are: double-split gate with rectangular weir for measuring and regulating the water flow rate, double-split gate with triangular weir for measuring and regulating water flow rate, set of weirs for the damming regulation, measurement and regulation of water flow on the check designed for the maximum damming level and hinged gate in the pipeline. The work is based on the expertise, the study of literature and field vision. The developed prototype devices are characterized by high functionality, as they can be installed on existing irrigation structures and can be used not only to measure and regulate the water flow rate, but also to control water retention in drainage and irrigation ditches in agricultural areas. The prototypes installed in the sub-irrigation systems will be tested in terms of the accuracy and complexity of the measurements and usefulness in irrigation conditions for controlling the water retention in ditches.

Drought is regarded as one of the environmental constraints threatening agriculture worldwide. Melatonin is a pleiotropic molecule prevalent in plants capable of promoting plant endogenous resilience to many environmental challenges including drought. Banana is an important staple food consumed in developing countries especially in Africa. In this research, we studied the role of melatonin in the growth of bananas subjected to drought under the Egyptian semi-arid conditions. To achieve this objective, a field experiment on banana (Musa spp., cv. Williams) mother plants and first ratoon was conducted on a private farm for two seasons - 2019 and 2020. Three irrigation treatments, 100, 90 and 80% irrigation water requirements (IWR) were used in conjunction with four concentrations of melatonin as a foliar spray (0 μmol, 40 μmol, 60 μmol, and 80 μmol) to determine the effect of both treatments on banana plant performance under drought. The results showed that there was a substantial difference between treatments, with the foliar application of melatonin at 80 μmol concentration improving most of the yield attributes, relative water content, total chlorophyll and proline with water deficit. However, the foliar application of the molecule lowered the biochemical characteristics mostly at 80% IWR under the Egyptian semi-arid conditions. Overall, there was a concentration-dependent response with regards to IWR for the two seasons 2019 and 2020.

Crop models of simulation are utilised effectively to evaluate the management of irrigation strategies which help in managing the water use. The aim of this study was to verify the validity of the Aquacrop model of maize under the surface and sprinkler irrigation systems, and a cultivation system, borders and furrows, and for two varieties of Maze (Fajr and Drakma) at two different sites in Iraq, i.e. the Babylon and Al-Qadisiyah governorates. The current study conducted an experiment to evaluate the Aquacrop model capacity in simulating canopy cover (CC), biomass (B), dry yield, harvest index (HI), and water productivity (WP). The results of RMSE, R2, MAE, d, NSE, CC, Pe indicated good results and high compatibility between the measured and simulated values. The highest achieved results were identical to the method of sprinkler irrigation due to the decrease in the amount of water consumed and the furrows cultivation method as the aerial roots were covered and the cultivar was Drakma. The highest values for the statistical data were $R^2$ (90 and 96%), RMSE (0.60, 0.73), MAE (0.5, 0.67), d (0.97, 0.97), NSE (0.87, 0.90), for the Babylon and Al-Qadisiyah sites, respectively. As for the CC values, they were very compatible with the values of $R^2$ and ranged between (92–99)%. The prediction error was Pe and minor errors were found. Thus, the Aquacrop model can be used reliably to evaluate the effectiveness of proposed irrigation management strategies for maize.

Opis:
The usefulness of estimating hourly reference evapotranspiration for assessing the water requirements of plants over a 24-hour period was determined in the study. The values of hourly (ET0,h) and daily (ET0,d) evapotranspiration were calculated using the Penman-Monteith (PM) model. The daily ET0 was calculated automatically by the meteorological station, and the evapotranspiration values for individual hours were calculated using spreadsheet software. To verify the values of evapotranspiration calculated with these two approaches in relation to the actual water needs of grass, lysimetric measurements were performed. Additionally, substrate moisture content and temperature were measured using capacitance probes. The values of evapotranspiration estimated with the hourly PM model were higher than those determined with the daily model. An accuracy of the hourly model in relation to the data measured with a weighing lysimeter depended largely on the quality of the reproduction of meteorological parameters at the site of the crop. Observed underestimation of the actual daily evapotranspiration was presumably due to the use of air temperature values in the calculations (measured at a height of 2 m by the weather station). During strong solar radiation the air temperature was much lower than the temperature of the upper layer of the substrate in the weighing lysimeter. Reference evapotranspiration was recalculated by introducing into the hourly PM model the measured values of substrate temperature. After taking into consideration the higher temperatures, the calculated values of evapotranspiration increased, and the regression model took the form: y = 1.01x + 0.014 (R2 = 0.90), which proves the proportionality of the calculated and measured (actual water needs determined with the weighing lysimeter) data. Reliable data on the hourly variations in evapotranspiration over a 24-hour period can be a great tool for use in controlling the irrigation of plants grown in a limited volume of substrate.

Opis:
The aim of the research was an evaluation of the frequency and intensity of agricultural droughts and their effects in the province of Kujawsko-Pomorskie as well as to indicate ways of increasing productivity in such drought periods by applying irrigation. It was found that the drought periods around Bydgoszcz occurred in 17 vegetation seasons out of 30 analysed. They were differentiated by intensity and duration but were also characterized by high irregularity of their occurrence. In the past 30-year period, droughts were especially intensified in the years 1989-1995. In the years 2001-2005 droughts were rare (36%), as compared with the previous 15-year period of 1986-2000 (64%). Crop production of some selected agricultural cultivations in the province of Kujawsko-Pomorskie depended to a large extent on the degree of precipitation shortages in the periods of intensified water demand. The best correlations and determination coefficients exceeding 80% concerned maize cultivations. The occurrence of droughts, expressed by the degree of atmospheric precipitation shortages in June and July, led to a decrease in grain crops in the province by 13%, on average. In the extremely dry year of 2006, a decrease by 27%, in relation to average crops, was observed. Active methods of minimizing effects of agricultural droughts are connected mainly with the development of irrigation systems. In the experiments conducted in the years 2006-2016, it was shown that the application of irrigation of barley and maize in the drought periods not only prevented 40-45% decrease in crops but also provided higher cropping level (by 33-40%) than the one obtained on average without irrigation.

Opis:
Spring frosts can cause very significant losses on fruit farms. The most common method of active protection against frost is sprinkling. The aim of this study was to assess the effectiveness of a sprinkling system used to protect apple trees against the effects of a spring frost. The experiment was conducted on the Mączewscy Fruit Farm. The orchard in which the observations were made is equipped with a system of sprinklers. When the temperature readings showed values close to zero, the sprinkler system was activated. Due to a limited water supply, one row of sprinklers had not been activated, and thus some of the trees were not sprayed at all. The assessment of fruit yield carried out in the autumn of 2015 demonstrated high effectiveness of the sprinkling used to protect apple trees against the spring frost. The frost had damaged most of the flowers of the unprotected trees, which resulted in a decrease in yield of as much as 85-93%.

Opis:
The aim of the research conducted in the conditions of Lower Silesia in the years 2012-2016 was to evaluate the growth and yielding of young peach trees cultivated in ridges with drip irrigation. The experiment concerned the flat-fruit peach trees, cultivar Saturn on the Manchurian peach tree seedling, planted in the spring of 2012 in the spacing 4.0 x 1.5 m. In each year the shortage of rainfall was observed, as compared to the years 1997-2000. During the vegetation period, the deficiencies were from - 7.3 mm up to - 221.7 mm. The insufficient amount of rainfall was accompanied by the rise of the mean air temperature in the vegetation period by 0.5 - 1.7°C. In the orchard, the drip irrigation in the form of stippling tape T-Tape TSX515-50-380 was applied, with the emitters every 50 cm and the expenditure of 3.8 l per metre in 1 hour. The humidity measurements were being taken from the beginning of May until the end of July with the use of Watermark probes, testing the sucking power of soil at the depth of 20 cm. The irrigation started when the water potential of soil was 30 kPa. During the 4 years, the total yield per hectare from the irrigated trees was by 5 t bigger than in the case of the trees that had not been irrigated. The irrigated trees cultivated in ridges had a tendency to more intensive radial growth. As far as the radial increase is concerned, statistically significant differences were noticed between the autumn of 2012 and the autumn of 2016. The application of irrigation also stimulated the elongation but only in the first two years of cultivation. The mean rate of proliferacy for the 4 years of fruiting was higher in the case of irrigated trees.

Chickpea is supposed to be a prospective crop for soil reclamation. The goal of this study was to determine the effect of tillage and humidification conditions on the chickpea desalination properties. The study was conducted by using the randomized split plot method in four replications during 2012–14 at the Agricultural Cooperative Farm «Radianska Zemlia» of Kherson region in Ukraine. The results of the study showed that the maximum salts uptake of 2.516 t ha-1 from the 0–50 cm soil layer and the maximum chickpea grain yield of 3.33 t ha-1 were provided under irrigated conditions with moldboard plowing on the depth of 28–30 cm. It was established that the higher chickpea grain yield is, the greater the salts uptake rate from the soil. It was also proven that the plowing depth has no significant effect on the chickpea grain yield and desalination properties. It should be mentioned that chickpea showed limited desalination properties. The crop was not able to adsorb all the sodium from the soil when irrigated with saline water.

Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and re-vegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Paddy production is the main agriculture of this area, has good climate, well irrigation and soil structure for paddy production. Both temperature and rainfall are the main climatic factors that affected the paddy cultivation. The main objective of the study is to find out the agricultural activities especially paddy cultivation. The sampling method has been used to collect the primary data through the questionnaire survey from 100 households and secondary data has been gathered form District Secretariat, Irrigation Report, and published research reports. MS Excel was utilized for the study to examine the changes of paddy production and other agriculture due to the irrigation water. As the result, paddy production was very high in the Maha season but it was low in Yala season because of the less rainfall and irrigation process. In addition, the highland crops were cultivated around 396 hectare in this area. Whatever, when compere with vegetable production, this was very low and the vegetable production was very high. Thus, these area people cultivate different kind of crops for their economy but have the less production. Therefore, the improvement of irrigation and other water body help to make much production can be produced more in highland crops cultivation. Proper management and better agricultural practices cause to the high production in future.

Warunki wodne są jednym z najbardziej zmiennych elementów środowiska glebowego. Woda stanowi podstawowy czynnik, który decyduje o wzroście i rozwoju roślin, a także o życiu mikroorganizmów glebowych i szeregu procesach zachodzących w glebie. Różne gleby zachowują różną wilgotność, mimo takich samych opadów atmosferycznych, zależy to od porowatości oraz od zdolności retencyjnych gleby. Ważną rolę w oszczędności wody zużywanej do nawodnień mogą odegrać systemy nawadniania. W artykule opisano wybrane zraszacze o szerokim zakresie funkcyjności, przeznaczone do nawadniania ogrodów, pól golfowych i dużych terenów zieleni. Parametry techniczne są kompatybilne z prawie wszystkimi istniejącymi systemami sterującymi automatyką nawadniania.
Water conditions are one of the most volatile components of the soil environment. Water is an essential factor that determines the growth and development of plants and soil microorganisms to life and a number of processes in the soil. Various soils retain different moisture, although the same precipitation, it depends on the porosity and the retention capacity of soil. Irrigation systems can play an important role in saving water used for irrigation. The article describes some of the sprinklers with a wide range of functionality designed to irrigate the gardens, golf courses and large green areas. Technical data are compatible with almost all existing automatic irrigation control systems.

This study investigates the hydrogeochemical characteristics and water quality of the Ghardaïa Continental Intercalare (CI) aquifer for domestic purposes and agricultural irrigation. Twenty-eight (28) grondwater samples were collected and analyzed for different physicochemical parameters. The result of the hydrochemical analysis illustrates that three facies dominate the CI waters: $SO_4-Na$, $Cl-Na$, and $HCO_3-Na$. The analysis of the correlation matrix and the characteristic ratios, as well as the calculations of the saturation indices of the main minerals, show that the mineralization of the waters is linked to the dissolution of evaporites (gypsum and halite in particular) and the cationic exchange phenomenon. The assessment of the potability of the water by using the water quality index (WQI) method shows three classes of water quality, namely, excellent (14.28%), good (7.14%), and poor (78.58%). The agricultural water quality was assessed using the parameters; EC, SAR, Na%, KR, PI and MH. The results show that the waters of the continental intercalare aquifer are generally of good quality for irrigation. However, the high salinity of the waters requires good drainage of the cultivated soils.

Greywater is an important water resource at the household level. The reuse of greywater is one of the most promising ways of conserving water because it has an important role in increasing plant productivity at the garden level. It is an important option to increase the efficiency of water use at the household level in rural Iraq. Through the implementation of a greywater treatment unit, this project sought to develop the treatment technology and encourage the local community in the target areas to reuse it. In this study, a greywater treatment unit that consists of a septic tank, up-flow anaerobic filter, and a storage tank is constructed on a specified area in the Khairi village in Al Diwaniyah province in Iraq. In order to ensure the quality of the treated greywater used in irrigation, an experimental verification and analysis of results were performed to demonstrate the improvement of physical, chemical and biological parameters. These parameters are COD, BOD, and TSS. According to the results of the study, the anaerobic filter (Subsurface Flow) was designed with one septic tank and three compartments. The total removal efficiency of COD, BOD, and TSS by greywater treatment unit was 92.27%, 96.9%, and 99.0%, respectively. The quality of the water produced by the greywater treatment unit was consistent with the FAO guidelines for reuse of treated water to irrigate domestic gardens.

The study was conducted in 2008-2009 at the Agricultural Experimental Station in Lipnik near Stargard, on sandy soil. The aim of this study was to determine the effect of sub-crown irrigation on the yield leaves photosynthesis and transpiration capacity, as well as CO2 concentration in the stomatal cells, and leaf greenness index of early ‚Geneva Early’ cv. and late ‚Rubinola’ cv. apple cultivars. Irrigation was applied in the form of the sub-crown system, in which water is distributed through a mini-sprayers of Hadar type when water potential of soil fell below - 0.01 MPa. The experiment was established in a randomized sub-block pattern (split-plot) in 10 replicates. The study was conducted using the four-year-old trees. The trees were planted at 4×2 m spacing; one hectare was planted with 1250 trees. Turf was maintained between the trees, while herbicide fallow was applied in rows. Plant material for laboratory tests was collected each year in three dates: fruit setting (date 1), harvest (date 2) and one month after the harvest (date 3). Studies have shown that leaves of the irrigated apple trees were lower content of assimilation pigments in leaves than non-irrigated ones. Leaves of late ‘Rubinola’ cv. showed higher photosynthetic activity and pigments content than early ‘Geneva Early’ cv. Pigment content was the highest at the second date of measurements. Better yielding late variety ‚Rubinola’ characterized by a greater intensity of transpiration, stomatal conductance and CO2 concentration leaves than the early va riety ‚Geneva Early’. The applied irrigation significantly increased the fruit yield and also increased the fruits weight of both varieties. Among the varieties of apple trees higher yield and fruit mass was found in the late variety ‚Rubinola’. This treatment and the earliness of varieties had no significant effect on the content of other macro- and micronutrients.

Opis:
The study identifies irrigation (sprinkler and slope) as a critical component in the biological reclamation and management of the municipal waste landfill in Boduszewo, the commune of Murowana Goślina in the Wielkopolska province. Irrigation was carried out in the vegetative periods during which, due to the rate and distribution of precipitation (2015 and 2016), it was considered necessary. The irrigation doses were determined corresponding to the water consumption by the vegetation covering the landfill. Results show that precise irrigation with the use of two complementary systems: sprinkler and slope, allows for the prevention and accurate control of the drought, resulting in continuous and uninterrupted growth and development of vegetation in the landfill. During the vegetative period of 2015, when the total precipitation (242 mm) was lower by 78 mm than the multi-year average for this season, rainfall deficiencies were supplemented by means of irrigation with doses from 18 mm to 25 mm. These were varied depending on the vegetation water consumption. On the southwest scarp of the landfill, the water consumption was 124 mm on average, whereas in the same period on the northeast scarp it was 46% lower. During the vegetative period of 2016, there was identified an additional need for irrigation of shrubs and trees. Sprinkler irrigation combined with slope irrigation was carried out with doses ranging from 25 mm to 35 mm, depending upon the water consumption by plants. During the vegetative period of 2017, there was no additional irrigation due to the favourable distribution of precipitation and its high rate (459 mm), higher than the multi-year average (by 139 mm), which retained optimal moisture in the root layer of grasses, trees and shrubs in the landfill. The use of irrigation of plants in the municipal waste landfill proved to be an indispensable process contributing to its effective and fast biological reclamation.
W pracy przedstawiono nawodnienie (deszczowniane i stokowe), jako jeden z elementów niezbędnych w przeprowadzeniu rekultywacji biologicznej, składowiska odpadów komunalnych we wsi Boduszewo, gmina Murowana Goślina w województwie Wielkopolskim. Nawodnienia prowadzono w okresach wegetacyjnych: 2015 i 2016 roku, w których ze względu na wysokość a przede wszystkim rozkład opadów występowała potrzeba nawadniania. Określono dawki polewowe, odpowiadające zużyciu wody przez rośliny pokrywające składowisko. Wykazano, że precyzyjne nawadnianie, przy pomocy dwóch uzupełniających się systemów: deszczownianego i stokowego, pozwala uniknąć i zapobiegać okresom suszy, wpływając tym samym na niezakłócony wzrost i rozwój roślinności na składowisku. W okresie wegetacyjnym 2015 roku, w którym suma opadów (242 mm), była niższą o 78 mm od średniej z wielolecia, występujące niedobory opadów uzupełniono nawadnianiem dawkami w ilości od 18 mm do 25 mm. Były one zróżnicowane w zależności od zużycia wody przez rośliny. Na skarpie południowo-zachodniej składowiska, zużycie wody wynosiło średnio 124 mm, podczas gdy w tym samym okresie na skarpie północno-wschodniej było o 46% niższe. W okresie wegetacyjnym 2016 roku, wystąpiła dodatkowo potrzeba nawadniania krzewów i drzew. Nawodnienie deszczowniane połączone ze stokowym przeprowadzono dawkami w ilości od 25 mm do 35 mm, uzależnionymi od zużycia wody przez rośliny. W okresie wegetacyjnym 2017 roku, nawodnień nie prowadzono, z powodu wystąpienia opadów o dużej wysokości (459 mm), wyższych od średniej z wielolecia (o 139 mm), a przede wszystkim korzystnego ich rozkładu. Spowodowały one optymalne uwilgotnienie w warstwie korzeniowej roślin trawiastych oraz drzew i krzewów na składowisku. Zastosowanie nawodnienia roślin na składowisku odpadów komunalnych, okazało się niezbędnym zabiegiem, przyczyniającym się do efektywnej i szybkiej jego rekultywacji biologicznej.

The presence of water, food and energy crises, both at the global and regional levels, as well as their deterioration under conditions of climate change, with an insufficient level of technical condition of existing irrigation systems, increase the strategic importance of irrigation as the guarantor of the agricultural sector sustainable development. This makes it necessary to increase, foremost, energy and overall (technical, technological, economic, and environmental) efficiency of the closed irrigation network of irrigation systems. In this regard, the complex that includes organisational-technological, technical, and resource-saving groups of measures was developed. Estimation of energy and overall efficiency of the closed irrigation network of irrigation systems at the implementation of developed complex were executed on the example of the agricultural enterprise located in the Petropavlovsk district of the Dnipropetrovsk region of Ukraine. For this purpose, machine experiment based on a use of the set of optimisation, forecasting and simulation models was implemented, including the model of climatic conditions, the model of water regime and water regulation technologies, as well as the model of crop yields on reclaimed lands. According to the obtained results, established that implementation of the complex reduces the consumption of irrigation water by 2.2-30.7% and electricity consumption by 12.9-38.2%. The rate of specific costs decreases from 1.6 to 1.32-1.47, and the coefficient of environmental reliability increases by 5.6-16.7%. At the same time, the profitability index increases from 1.07 to 1.75-2.57, and the discounted payback period decreases from 18 to 8-5 years.

The paper concerns evaluation of the exploitation of the world’s water resources for irrigating field crops. It was determined that the volume of water used in 2020 in all sectors of the economy in relation to the world’s freshwater resources will amount to 31 to 38% of the available resources. It has been found that globally, in the period 1900–2100, the agricultural sector has the highest consumption of fresh water. Therefore, there is a need for rational use of water, especially when irrigating field crops. Hence, the paper describes the methods of evaluating the effectiveness of irrigation. The indicators from the Water use efficiency group, which consider the yield obtained from a given area and the sum of irrigation doses, were considered the most reliable form of evaluation. Determining the indicator should also be accompanied by a presentation of the scope of work related to irrigation, water quality, cultivation techniques, fertilization and environmental conditions of the growing season. The work characterizes the selected pressure irrigation systems, considering their advantages and disadvantages. On this basis, the paper presents the adaptation of the SWOT analysis for two irrigation systems: a reel sprinkler with a water cannon and a drip tape.

Opis:
CropSyst (Cropping Systems Simulation) is used as an analytic tool for studying irrigation water management to increase wheat productivity. Therefore, two field experiments were conducted to 1) calibrate CropSyst model for wheat grown under sprinkler and drip irrigation systems, 2) to use the simulation results to analyse the relationship between applied irrigation amount and the resulted yield and 3) to simulate the effect of saving irrigation water on wheat yield. Drip irrigation system in three treatments (100%, 75% and 50% of crop evapotranspiration – ETc) and under sprinkler irrigation system in five treatments (100%, 80%, 60%, 40%, and 20% of ETc) were imposed on these experiments. Results using CropSyst calibration revealed that results of using CropSyst calibration revealed that the model was able to predict wheat grain and biological yield, with high degree of accuracy. Using 100% ETc under drip system resulted in very low water stress index (WSI = 0.008), whereas using 100% ETc sprinkler system resulted in WSI = 0.1, which proved that application of 100% ETc enough to ensure high yield. The rest of deficit irrigation treatments resulted in high yield losses. Simulation of application of 90% ETc not only reduced yield losses to either irrigation system, but also increased land and water productivity. Thus, it can be recommended to apply irrigation water to wheat equal to 90% ETc to save on the applied water and increase water productivity.
CrosSyst (ang. Cropping Systems Simulation) wykorzystano jako narzędzie analityczne do zarządzania wodą do nawodnień w celu zwiększenia produktywności pszenicy. Przeprowadzono dwa eksperymenty terenowe w celu: 1) kalibracji modelu CropSyst w odniesieniu do pszenicy uprawianej w warunkach nawodnień deszczownianych i kroplowych, 2) zastosowania wyników symulacji do analizy zależności między wielkością nawodnień a plonem i 3) symulacji wpływu oszczędności wody użytej do nawodnień na plon pszenicy. W eksperymentach zastosowano trzy warianty nawodnień kroplowych (100%, 75% i 50% ewapotranspiracji – ETc) i pięć wariantów nawadniania deszczownianego (100%, 80%, 60%, 40% i 20% ETc). Wyniki kalibracji wykazały, że wartość RMSE wynosiła 0,03 i 0,14 t·ha–1 odpowiednio dla ziarna i biomasy. Model umożliwiał symulację dobowego stresu wodnego w ciągu całego sezonu wegetacyjnego. W wariancie 90% ETc nie tylko stwierdzono zmniejszenie strat plonu w każdym z systemów nawodnień, ale także zwiększenie produktywności wody. Dlatego można zalecić stosowanie dawki 90% ETc w celu oszczędności wody i zwiększenia jej produktywności.

Its purpose was to observe grape production quality parameters, such as yield, water productivity, berry size and bio-mass. Different irrigation methods, such as drip irrigation (DI), drip irrigation with plastic mulching (DIPM), drip irrigation with organic mulching (DIOM), subsurface irrigation with stone column (SISC), subsurface irrigation with mud pot (SIMP), and subsurface irrigation with plastic bottles (SIPB) have been used during the experimental work. The crop has been irrigated following the CROPWAT-8.0 model developed by the FAO. Climate parameters are obtained from the automatic weather station located near the experimental field. Based on experimental results and analyses, it has been observed that the drip irrigation with the plastic mulching method is the best for irrigation in terms of the grape yield comparing with all other methods due to its highest productivity of 35–40%. Subsurface irrigation with the plastic bottle method is found to be suitable as it gives 20% higher yield than the traditional drip irrigation method. The SIPB method shows the cost-benefit ratio of 112.3, whereas the DIPM method had the ratio of 36.6. Based on the cost-benefit analysis, it is concluded that the SIPB method is economically more viable as compared with all other methods. Hence, based on the findings, it is recommended to use drip irrigation with a plastic mulching and drip irrigation with a plastic bottle as the best options to achieve grape productivity while using minimum water.

Opis:
W pracy zaprezentowano ocenę ekonomiczno-finansowej efektywności deszczownianego nawadniania ogórków w produkcyjnym gospodarstwie ogrodniczym. Ocena ta została przeprowadzona metodą zdyskontowanych przepływów pieniężnych (DCF). Jej podstawą były wyniki badań parametrów istotnych w rachunku efektywności (m.in. zwyżki plonów i przychodów ze sprzedaży ogórków na skutek nawodnień, kosztów zakupu i eksploatacji deszczowni). Badania wykazały, że zwyżka plonów na skutek nawodnień w latach badań wynosiła od 3,0 do 9,1 t•ha-1 (średnia 6,6 t•ha-1), a produktywność nawodnień, mierzona zwyżką plonów na m3 wody, w granicach 6,0‒19,2 kg (średnia 14,5 kg). Finansowa wewnętrzna stopa zwrotu z nawodnień (FRR) wyniosła 63%, finansowa aktualna wartość netto (FNPV) w warunkach stopy dyskontowej r = 6% równa się 21,8 tys. zł, wskaźnik FBCR = 1,64, a czas zwrotu nakładów inwestycyjnych wyniósł 1,5 roku. Wskaźniki te dowodzą, że nawadnianie ogórków jest ekonomicznie uzasadnione.
The paper presents an assessment of the economic and financial efficiency of sprinkler irrigation of cucumbers in vegetable farm production. This assessment was carried out using the discounted cash flow method (DCF). The base of calculation was the results of research parameters which are important in the statement efficiency (including increases in yields and revenues from the sale of cucumbers as a result of irrigation, the capital expenditures and operating costs of irrigation). Studies have shown that increases yields through irrigation in the study ranged from 3.0 to 9.1 t∙ha-1 (average 6.6 t∙ha-1) and the productivity of irrigation measured rise in the yields per m3 of water was in the range 6.0‒19.2 kg (mean 14.5 kg). The financial internal rate of return (FRR) was 63%, financial net present value (FNPV) under the discount rate r = 6% equals 21.8 thousand PLN, FBCR = 1.64, and the payback time was 1.5 years. These indicator shows that irrigation cucumber is economically justified.

Opis:
The water supply deficit requires agro-environmental rationale for the use of alternative water sources to feed agricultural crops, viz.: industrial wastes, municipal drains, farm animal waste, drainage and escape water of rice irrigation systems. We analyzed the quality of irrigation water from different sources, with regard to the content of cations, anions, water-soluble salts, power of hydrogen (рН), sodium adsorption ratio (SAR), etc. in it. In the course of the greenhouse trial, we diagnosed its impact on the indicator crop (maize) (Zea mays L.) with its herbage crop stage of 10 leaves, supplied with water of varying quality. We proved the viability of improved drainage and escape water from rice irrigation systems in irrigated agriculture, owing to which maize herbage was diminished, on average, by 5.82%. We verified the negative impact of irrigation water, which contains the effluent disposals of metallurgical production, on croppers – it had contributed to diminishing the watered maize herb, on average, by 39.27%. A correlation analysis of the test data proved the closely interrelated feedback between the maize herbage amount and the content of cations, anions and water-soluble salts in irrigation water (coefficient of correlation r varied between 0.88 and 0.98). The worked-out linear regressive model for maize herbage, based on the content of water-soluble salts in irrigation water, together with SAR index (Y=2342.71–1.82×x1+366.78×x2), affirmed the validity of the pattern, discovered by means of the correlation analysis.

Opis:
The prosperity of Egyptian civilization has depended on the efficient use of water deriving from the Nile throughout its recorded history. Despite the importance of water and irrigation in ancient Egypt, very little is known of its water regulations. The only known legal source related directly to the maintenance of canals that has been preserved is a section of the Dikaiomata – the Alexandrian city law dealing with the construction and improvement of irrigation channels in the surrounding countryside. However, being Greek in origin, it does not seem to correspond to the legal practice that has been in use in Egypt since the earliest times. How water regulations looked like in practice can therefore only be observed by means of practice documents, i.e. papyri from Ptolemaic period. Such papyri recorded the law in action, both in relation to individuals as well as the whole society in the context of water management. These documents and their similarities and differences to the rules contained in Dikaiomata are the subject of the paper.

The main objective of this work was to study the status of groundwater quality for drinking and irrigation uses in the locality of Beni Ounif. A total of 16 samples were taken at different locations in the study area from boreholes to capture the continental intercalary (CI) aquifer for physicochemical analysis. This work used the groundwater quality index (GWQI) method to evaluate water potability. The irrigation water quality was assessed by studying EC, SAR, Na%, KR, PI, and MR parameters. In addition, the mechanisms of mineralization of these waters were highlighted by the study of Piper, Gibbs, bivariate diagrams, and the calculation of saturation indices. The results show that the CI waters would have chemical constituents in accordance with the WHO guide values and the Algerian guide values for drinking water. The GWQI method showed a good quality of CI waters for consumption in the study area. On based the irrigation water parameters, the IC water samples are acceptable for irrigation provided that drainage techniques are applied to the cultivated land for tipsy soil salinization. In addition, the study of Piper, Gibbs, bivariate, and mineral saturation diagrams shows that the CI waters of the study area are of Ca-Mg-SO4-Cl type, and the hydrogeochemical processes that control their mineralization are complex, namely, the alteration of silicate and carbonate minerals, the dissolution of gypsum and exchange ion.

The location of a significant part of the agricultural territories of Kazakhstan in the risk agriculture zone implies the development and further application of an objective monitoring system for irrigated territories. The purpose of the study was to develop methods for on-the-spot and long-term recognition of irrigated massifs and verification of methods in the conditions of the territories of southern Kazakhstan. The paper describes the methods of on-the-spot recognition of irrigated fields, the general assessment of irrigated areas for the growing season, as well as the method of recognizing promising areas for irrigation. The on-the-spot recognition of the fields is based on the use of such spectral indices as the Global Vegetation Moisture Index, Green Normalized Difference Vegetation Index, Normalized Difference Vegetation Index, and the xanthophyll index, combined into a single system by the Decision Tree algorithm. The assessment of irrigated areas is based on differences in the physiological state of plants in conditions of normal water supply and plants experiencing a lack of moisture. The evaluation system includes the calculation of the temperature difference according to the corresponding satellite data and the calculation of the difference in vegetation indices for the same period. The difference in vegetation indices in irrigated fields has positive values due to a steady increase in green biomass, and the temperature difference, on the contrary, is negative or zero, since healthy plants, with normal water supply, actively evaporate moisture to maintain optimal temperatures of biochemical processes. To develop these methods, ground data from 2017–2021 were used. Verification of the methods with ground data demonstrated acceptable accuracy (87% in the on-the-spot assessment of irrigated fields; 60–90% in the general assessment of irrigated areas), while the methods have significant potential for further improvement.

Opis:
Questions of reuse of drainage water and wastewater of rice systems on the example of rice irrigation systems are determined. The technological scheme, which saves water and energy resources during the irrigation of crops in the rice system, is proposed. Calculations of economic efficiency of water circulation technology in the Danube rice irrigation systems (RIS) with drainage water and wastewater (DWW) dilution with fresh water in the ratio of 1 : 1 showed that the net profit will amount to UAH 26,266.5 per 1 ha, while the dilution in the ratio of 1 : 2 – to UAH 26,161.5 per 1 ha. Complementary net profit will accordingly amount to UAH 1,337.8 and 1,231.5 per 1 ha. The most perspective technique to use DWW in rice irrigation systems is their reuse with dilution with fresh water at a ratio of 1 : 1 or 1 : 2. This ratio corresponds to most indicators for which was done an evaluation of water that is supplied for irrigation. Also this ratio does not lead to deterioration of soil salt regime.

In this research, estimation potential of Aquacrop model under deficit irrigation and salinity conditions were evaluated for winter wheat grown under arid and semi-arid climates. Five different irrigation strategies and irrigation water salinity levels (0.5, 5, 7.5, 10, 15 dS m-1 ) were taken with the model to estimate deficit irrigation and salinity scenarios. Wheat grain yield, biomass production and canopy cover were simulated under deficit and salinity stresses. According to estimation of the model; the deficit irrigation with water reduction of more than 75 % of full irrigation was applied at growth stages of wheat, revealed the significant reduction in grain yield, biomass and canopy cover as compared with full irrigation practice. The increase in irrigation water salinity caused a significant decrease in grain yield and biomass value. It was compared to the 0.5 dS m-1 salinity level, a low value of 3% was obtained for the 5 dS m-1 salinity level. Yield loss of 7.5, 10 and 15 dS m-1 salinity levels were found to be 18.97%, 42.5% and 85.6% respectively. Also, increasing irrigation water depth in saline treatments resulted in increased grain and biomass yield. For sustainable water management in agriculture area, using simulation model such as Aquacrop is useful tolls to estimate effect of applied water depth and quality of irrigation water on crop yield.

Water is an important part of all living things, including humans, animals, and plants, but concern for clean water is decreasing due to numerous human activities, which cause pollution. Water pollution is characterized by changes in physical, chemical and biological contents due to the wastes generated from the actions of living things, such as water irrigation. Therefore, this research aimed to overcome irrigation wastewater pollution using the Internet of Things (IoT)-based phytoremediation method, water hyacinth, apu-apu, and lotus. It was carried out using a tool monitoring system based on IoT technology with parameters for measuring pH, temperature, and water turbidity through the internet network. The results showed that the acidity level increased by 7–8 with a decrease in COD using water hyacinth, apu-apu, and lotus by 41.55%, 32.77%, and 32.91%, respectively. The BOD level using water hyacinth, as well as apu-apu and lotus decreased by 37.82%, and 31.54%, respectively. The decrease in phosphate level using water hyacinth, apu-apu and lotus was by 3.55%. Finally, the decrease in nitrate level using water hyacinth plants, apu-apu and lotus was 13.83%, 9.61% and 19.61%, respectively.

The purpose of this study was to estimate the water needs of grapevines in central Poland in 1981-2010. Water needs were calculated by the plant coefficients, which were assumed according to the Doorenbos and Pruitt method. Reference evapotranspiration was assessed by the Blaney-Criddle’s equation, modified for Polish conditions. Rainfall deficit with the occurrence probability of normal, medium dry and very dry years was determined by the Ostromęcki’s method. Water needs of grapevines during the growing season was 434 mm. Upward time trend in the water needs both in the periods May-October and June-August was estimated. Temporal variability in the water needs was significant for most of the provinces. The rainfall deficit was recorded with the occurrence probability of normal as well as medium or very dry years in the entire study area. Due to climate changes, vineyards will require irrigation in the near future. This research significantly broadens and refines the knowledge about the water needs of grapevines in central Poland, which will allow the design of resource-efficient irrigation programs for grapevines in the studied region of Poland.

The rainfall irregularity in the Al-Hoceima area places the Ghis-Nekor coastal aquifer as a primary resource for water supply. However, it is of paramount priority to adopt management and optimization plans that can mitigate the effects of the irrational use of the resource and the deterioration of its quality in the region of our study. In order to study the alteration aspects of this aquifer, 26 wells were sampled and their suitability for irrigation was assessed. The sodium adsorption rate (SAR) values indicate that most groundwater samples fall into the risk classes of high salinity and low sodium (C3-S1) and high salinity and medium sodium (C3-S2). The results also show a medium to high alkalinity risk due to the high concentration of HCO3-. The excess of salts is largely due to the intensive exploitation of groundwater and to the phenomenon of salt-water intrusion into the coastal karst aquifer. As a result, the quality of groundwater is not adapted to sustainable agricultural production and soil balance, which requires controlled monitoring to ensure its rational use with a view to the sustainable development of the region.

The paper analyses the scales and results of well irrigation campaigns sponsored by the government in the mid-eighteen century and the late nineteenth century. Limited by the natural environment and technical conditions, the eficiency of well irrigation is poor. Farmers' choices also afect the development of well irrigation. Moreover, a lack of management led to the unsustainable use of groundwater. Historical groundwater policies were mainly aimed at increasing agricultural production. Policies should be made according to local conditions. It is important to ensure the sustainable development of groundwater.

The ash-leaved maple (Acer negundo L.) has low habitat requirements, which is why this species is often used in the reclamation of industrial areas. The development of the reclamation plantings depends on the optimal water soil conditions that can be controlled by watering treatments. However, the use of irrigation requires determining the water needs of the cultivated species. The objective of the study was to evaluate the water needs of the ash-leaved maple in the reclamation plantings, in the period of over three years after planting. The water needs of the ash-leaved maple were determined using the crop coefficients method. Potential evapotranspiration was calculated using the Blaney-Criddle’s formula that was modified for the Polish conditions by Żakowicz. The water needs of the ash-leaved maple were assessed for five agro-climatic regions of Poland, in the years 1981-2010. The water needs of the ash-leaved maple in the growing period (April-October) were the highest in the C-E (638 mm) and C-N-W (637 mm) regions, and the lowest in the N-E (598 mm) and S-E (601 mm) regions. In July, the highest water needs were noted in the C-N-W region (149 mm) and the lowest in the S-W region (129 mm). In the studied thirty-years period, there was a significant upward trend in the water needs of the ash-leaved maple both during the growing season (except for the C-N-W region) and in July, in all the considered regions.

Opis:
The suitability of capacitance probes for measuring the actual variations in substrate water content in container-grown ornamental species (Lawson cypress) was examined. The probes were installed in the plant containers. Weighing measurement data on water loss was used to assess the actual changes in substrate water content (plant water use). In an additional test, an evaluation of temperature sensitivity of the capacitance probe was performed under laboratory conditions. The probe was placed in a container containing the growing medium (peat substrate) with a defined (stable) moisture content. The substrate temperature was modified and the changes in probe output were recorded. The experiment demonstrated the existence of the effect of temperature on the quality of soil moisture measurements conducted with the capacitance method. The accuracy of the results obtained from measurements with dielectric sensors in relation to the data obtained by means of weighing platforms depended largely on the temperature profile of the measured medium. It was demonstrated that temperature variations explained 99% of the observed differences in the results of moisture content measured with the capacitance method. Due to the fact that there is no possibility of developing universal factors (for different sensors and substrates) for correcting the influence of temperature, this relationship should be defined independently for a given type of crop and the measuring system available.

Opis:
In the past few years, Poland has been growing into a leader in the cultivation of highbush blueberry in Europe and now occupies a very high 3rd place in world production, just behind the USA and Canada. The leading position on the European market, the growing demand for the fruit and the possibility of entering new markets present to Polish producers new opportunities and increase the number of new plantings. In the cultivation of blueberry, irrigation is a factor determining the size and quality of the crop, as the blueberry plant, due to its shallow root system, requires adequate moisture and permeability in the topsoil, generally throughout the entire growing period. The results obtained in several studies confirm the high effectiveness of blueberry irrigation, particularly on plantations at their full fruiting potential. The rise in yield achieved through the use of irrigation averaged 95%, corresponding to 4.51 t·ha-1. The average irrigation efficiency coefficient was a 41.37 kg rise in fruit yield per 1 mm (10 m3) of water used for irrigation.

Opis:
The Coastal Chaouia region is located south of the Casablanca city (Morocco). Since the 1970s, groundwater has been used intensively for irrigation, previously for growing citrus and currently for vegetables and forages. The increase of irrigated soils by pumping has induced environmental problems such as the degradation of groundwater quality and salt water intrusion. For these reasons, this work aimed to study the impact of the irrigation water quality upon the agricultural soils. During the study, 71 samples of well water and soil were taken to represent the whole considered area, which comprised 3 different zones (0–1.8 km, 1.8–4.5 km, and 4.5–11 km from the coast). The analyzed parameters were salinity and pH. The results showed firstly that the soil pH average values decrease for the three zones with 7.73, 7.57, and 7.52, respectively. However, the water pH averages vary from 7.24 to 7.49. For the soil electrical conductivity, it represents a light decrease moving from the nearest zone to the sea to the far one (average of 3.54, 2.66, and 2.33, respectively). A similar result is for observed water electrical conductivity with average of 6.83, 5.30, and 2.06, respectively, for the three zones. The analyses of the soil and water salinity show that both salinities decreased moving from the coast to inland. Richard and Wilcox charts have confirmed the strong mineralization and the poor quality of most of the well water which are close to the sea.

Opis:
In this study, field experiment has been carried out on the grape yard during the summer, Rainy, and winter seasons using different irrigation methods and measuring its impact on moisture retention. Six different irrigation methods such as drip irrigation (DI), drip irrigation with plastic mulching (DIPM), drip irrigation with organic mulching (DIOM), subsurface irrigation with stone column (SISC), subsurface irrigation with mud pot (SIMP), and subsurface irrigation with plastic bottles (SIPB) are used during experimental work. CROPWAT-8.0 model (FAO) is used to find out crop water requirements. Soil moisture is measured using soil moisture sensors fixed in the depth of 30 and 60 cm at the same location. Climatic parameters are obtained from the automatic weather station which is located near the experimental field. Multifactorial statistical analysis has been carried out using recorded soil moisture and climatic data. As per experimental results and analysis, it is observed that drip irrigation with the plastic mulching method is found to be the best method of irrigation for soil moisture retention among all other methods due to its highest soil moisture retention value as 25–30%. Whereas subsurface irrigation with the plastic bottle method is found to be suitable as it retained 15–20% soil moisture and material used in this irrigation method is waste material and the cheapest one.
Przeprowadzono eksperyment polowy w winnicy w czasie lata, pory mokrej i zimowej, stosując różne metody nawadniania i mierząc jego wpływ na zachowanie wilgotności w glebie. Zastosowano sześć metod nawadniania: nawadnianie kroplowe, nawadnianie kroplowe z przykrywaniem syntetyczną włókniną, nawadnianie kroplowe z mulczowaniem organicznym, podpowierzchniowe nawadnianie z kolumnami z kamieni, podpowierzchniowe nawadnianie z glinianymi naczyniami i nawadnianie za pomocą butelek plastikowych. Do oceny zapotrzebowania uprawy na wodę zastosowano model CROPWAT 8.0. Wilgotność gleby mierzono czujnikami wprowadzonymi do gleby na głębokość 30 i 60 cm. Parametry klimatyczne uzyskano z automatycznej stacji pogodowej usytuowanej w pobliżu pola doświadczalnego. Wieloczynnikową analizę statystyczną przeprowadzono z wykorzystaniem pomierzonej wilgotności gleby i danych klimatycznych. Metoda kroplowego nawadniania z przykrywaniem syntetyczną włókniną okazała się najlepsza spośród wszystkich zastosowanych metod z powodu największej retencji wilgoci glebowej (25–30%). Użyteczna okazała się także metoda podpowierzchniowego nawadniania z plastikowymi butelkami, ponieważ zatrzymywała 15–20% wilgoci glebowej.

Opis:
The objective of this study was to show the possibilities for drought mitigation in vegetable plant growing on loose sandy soils in the region of Bydgoszcz with the use of drip irrigation system. Drip irrigation used under such the soil-climatic conditions was the basic vegetable yield-creating factor, securing stable yields of the vegetable crops tested in period 1991–1999 (carrot, red beet, snap bean, squash, zucchini). The results indicated the decisive role of water on the outcome of yield and quality of vegetables cultivated on a soil of limited water holding capacity. The experiments proved that vegetables production on sandy soils was only possible with the use of supplemental irrigation. Using the elaborated formulas it is possible to determine critical periods for individual vegetable species, optimal rainfall during these periods as well as expected increases of yields caused by drip irrigation covering rainfall deficits. According to the elaborated dependences, the approximated estimation of average needs of drip irrigation and average production effects of irrigation in particular rainfall regions is also possible.
Celem badań było ukazanie możliwości zapobiegania suszy w uprawie warzyw na luźnych glebach piaszczystych w regionie Bydgoszczy poprzez użycie nawadniania kroplowego. Zastosowane w takich warunkach klimatyczno-glebowych nawadnianie kroplowe było podstawowym czynnikiem plonotwórczym, zapewniającym stabilne plony badanych warzyw (marchwi, buraka ćwikłowego, fasoli szparagowej, dyni i cukinii). Wyniki potwierdziły podstawową rolą wody w uzyskiwaniu plonów warzyw na glebie o ograniczonej pojemności wodnej. Doświadczenia dowiodły, że uprawa warzyw na glebach piaszczystych jest możliwa wyłącznie przy zastosowaniu nawadniania uzupełniającego. Stosując opracowane formuły, możliwe jest określenie okresów krytycznych dla poszczególnych gatunków roślin, opadów optymalnych dla tych okresów oraz spodziewanych przyrostów plonów spowodowanych nawadnianiem kroplowym pokrywającym deficyty opadów. Dzięki opracowanym zależnościom szacunkowa ocena przeciętnych potrzeb nawadniania kroplowego i efektów produkcyjnych nawadniania w poszczególnych regionach opadowych również jest możliwa.

W pracy zaprezentowano ocenę produkcyjnej i ekonomiczno-finansowej efektywności kroplowego nawadniania borówki wysokiej. Badania prowadzono w latach 2008–2015 na powierzchni 4,0– 4,5 ha, w produkcyjnym gospodarstwie rolnym. Roczne dawki nawodnieniowe wynosiły od 145 do 333 mm i były podawane w 24–32 cyklach nawodnieniowych trwających od 3 do 6 godzin. Badania wykazały, że średnia zwyżka plonów na skutek nawodnień wynosiła 6,76 t∙ha -1 (132%), produktywność nawodnień mierzona zwyżką plonów na m3 wody to 3,2 kg, a ceny handlowe owoców z plantacji nawadnianej były wyższe średnio o 1,56 zł•kg-1 (11%) niż z plantacji nienawadnianej. Ocena ekonomiczno-finansowa przeprowadzona metodą zdyskontowanych przepływów pieniężnych (DCF) wykazała, że finansowa wewnętrzna stopa zwrotu z nawodnień (FRR) wyniosła 544%, finansowa aktualna wartość netto (FNPV) w warunkach stopy dyskontowej r = 6% równa się 2039,0 tys. zł (501,9 tys. zł∙ha-1), a nakłady inwestycyjne na system nawadniający stanowiły tylko 20% zwyżki dochodu w pierwszym roku nawodnień. Wskaźniki te są wyjątkowo wysokie i wskazują na celowość nawadniania borówki.
The paper presents an assessment of production and financial viability of drip irrigation of highbush blueberry, on the surface of 4.0–4.5 ha. The study was conducted in 2008–2015 in farm. Annual irrigation doses ranged from 145 to 333 mm and were applied in 24–32 irrigation cycles lasting from 3 to 6 hours. Studies have shown that increases yields thank to irrigation were 6.76 t∙ha-1 (132%). Irrigation productivity, measured rise of the harvest per m3 of water – 3.2 kg, but the commercial price of fruit on irrigated plantations are higher average of 1.56 PLN∙kg-1 (11%) than from no irrigated plantations. Economic and financial assessment of carried out using the discounted cash flow (DCF) analysis showed that the financial internal rate of return from irrigation (FRR) was 544%, financial net present value (FNPV) under the discount rate r = 6% equals 2039.0 thousand PLN (501.9 thousand PLN∙ha-1), and investment cost on irrigation system accounted for only 20% increases of net revenue in the first year of irrigation. These indicators are extremely high and indicate the advisability of blueberries irrigation.

Opis:
Irrigation in developing countries tends to be stereotyped as equity reducing, in competition with other uses for scarce water resources, often negatively impacting disadvantaged groups. This study aims to clarify the linkages between irrigation and poverty by offering an objective review of recent research on the subject. The key questions addressed herein are: (1) what is the role of irrigation development and management in poverty alleviation? (2) what are the linkages and pathways through which irrigation contributes to poverty alleviation? (3) what is the magnitude of anti-poverty impacts of irrigation? And (4) what are the critical determinants of anti-poverty impacts of irrigation? Our review focuses on topical empirical research studies in West Java Province, Indonesia. Agricultural intensification through the practice of irrigation as a strategy for poverty reduction is examined. There are four inter‐related mechanisms through which irrigated agriculture can reduce poverty. These are improvements in the levels and security of productivity, employment, and incomes for irrigating farm households and farm labor; the linkage and multiplier effects of agricultural intensification for the broader economy; provision of opportunities for diversification of rural livelihoods; and multiple uses of irrigation supply. There are also significant risks that poorly designed and managed irrigation can negatively impact on poverty. It is concluded that two factors of production (irrigation and literacy rate) have a larger role in the overall rural development and poverty alleviation process in a region, as also clearly illustrated in this study's regression results.

Study on soil infiltration rate as part of water cycle is essential for managing water resources and designing irrigation systems. The present study was conducted with the aim to compare Kriging, inverse distance weighting (IDW), multilayer perceptron (MLP) and principal component analysis (PCA) methods in the interpolation of soil infiltration in furrow irrigation, and determine the best interpolation method. To conduct infiltration tests, furrows were made on the farm in four triad groups. Infiltration through the blocked furrows method was measured 10, 20, 30, 40, 50, 60, 90, 120, 150, 160, 180 and 210 min after irrigation at a 10-meter distance in each furrow. Data were analyzed by GS+ and Neuro Solutions (NS) software packages. In this study, the maximum error (ME), mean bias error (MBE), mean absolute error (MAE), root mean square error (RMSE), relative error (RE) and correlation coefficient (r) were used to compare the interpolation methods. The results of analysis of variance (ANOVA) indicated that differences in methods based on RMSE, MBE, MAE and ME indices were not significant; however, this difference was significant based on r and RE indices. According to the ANOVA results, it can be said that the PCA method with a r of 0.69 and RE of 31%, was predicted with a higher accuracy as compared to other methods.

W opracowaniu przeanalizowano wpływ nawadniania plantacji odmian ziemniaka jadalnego na wzrost poziomu plonu ogólnego oraz zmianą udziału plonu handlowego w plonie ogólnym. Skalkulowano także opłacalność stosowania nawadniania uwzględniając przy tym poniesione koszty bezpośrednie oraz wartość uzyskanego plonu. Stwierdzono, że w przypadku wystąpienia suszy w okresie wegetacji przyrost plonu ziemniaków pod wpływem nawadniania w ekologicznym systemie gospodarowania może dochodzić do 25%. Poprawie ulega także jakość plonu, co wyraża się zwiększonym plonem handlowym. Względnie wysokie koszty prowadzenia nawadniania systemem linii kroplujących są w pełni rekompensowane przyrostem wartości plonu. Stosowanie nawadniania można również wykorzystać do zwiększenia produkcji biomasy pozyskiwanej z uprawy międzyplonów, a służącej na przyoranie.
In the paper, an influence of potato irrigation on higher level of total yield and changing share of market yield in total yield were evaluated. Profitability of using of drip irrigation was calculated taking into account the expenses and value of yield. Is was shown that in case ofdrought during the vegetation period yield the increase of potato yield due to irrigation in ecological system may achieve up to 25%. Potato quality is improved which is expressed by increased market yield. Relative high cost of drip irrigation are fully refund by increasing value of potato market yield. It is also possible to use the irrigation for increasing biomass production which comes from intercrop production used for ploughing.

The paper presents analysis of the impact of irrigation dose on the winter wheat Bystra yield, which is recommended for cultivation in Poland. It is a low-growing high-yield wheat cultivar. A reel sprinkler equipped with a computer for control of parameters of its operation, which was supplied with pond water was used for irrigation. Test were carried out on five fields, where four irrigation doses were used: 15, 20, 25, 30 mm. A change of weather during research in May and June caused the need to irrigate a field four times. During research, the size of the irrigation dose was measured with rain gauges on each of the investigated fields in five measurement points. One of the fields was a control field, which was not irrigated. The investigated wheat was characterized during harvesting. Research proved that the size of the irrigation dose influences the wheat yield. The grain yield between a control field and a field with the highest irrigation dose increased by twofold. Moreover, analysis of costs incurred during sprinkling were analysed.
W pracy przedstawiono analizę wpływu wielkości dawki nawadniania na plon pszenicy ozimej Bystra, która jest rekomendowana do uprawy w Polsce. Jest odmianą pszenicy niskopiennej o wysokim plonowaniu. Do nawadniania użyto deszczowni szpulowej wyposażonej w komputer do sterowania parametrami jej pracy, którą zasilano wodą ze stawu. Badania przeprowadzono na pięciu poletkach, na których stosowano cztery dawki nawadniania: 15, 20, 25, 30 mm. Zmiana pogody podczas badań w maju i czerwcu spowodowała konieczność czterokrotnego nawadnianie pola. W czasie badań mierzono wielkość dawki irygacji za pomocą deszczomierzy na każdym z badanych poletek w pięciu punktach pomiarowych. Jedno z poletek było poletkiem kontrolnym, które nie było nawadniane. W czasie zbioru dokonano charakterystyki badanej pszenicy. Badania dowiodły, że wielkość dawki nawadniania ma wpływ na plon pszenicy. Plon ziarna między poletkiem kontrolnym, a poletkiem o największej dawce nawadniania wzrósł 2-krotnie. Dodatkowo dokonano analizy kosztów poniesionych w trakcie deszczowania.

Opis:
The objective of this work is the agroecological substantiation of the use of treated wastewater for irrigation of agricultural land. As the result of the experimental research, it was established that the soil microflora plays an essential role in strengthening or weakening the biological activity of soil. Therefore, with an irrigation rate of 250 m3/ha of wastewater, a 1.5 times increase in the number of microbiota colonies is observed on average both in hog farms and cattle breeding complexes; with a rate of 350 m3/ha – a 2-fold increase; with a rate of 450 m3/ha – a 3.5–4-fold increase. An increase in nitrifying soil features has also been observed. Thus, if the value on the control in the soil layer from 0 cm to 60 cm is 27.2 mg of nitrate per 1 kg of arid soil, in the version with wastewater irrigation it reaches 46.7 mg. According to the research results, the use of defecate, the waste of sugar production, in the treatment of wastewater of livestock farms does not have a negative agroecological impact on the soil. Therefore, the method of wastewater treatment of pig-breeding complexes and farms can be recommended for use in irrigation reclamation, which includes treatment of wastewater with burnt defecate in the dose of 50–200 mg/dm3, with the pH value varying in the range of 7.5–8.5. After settling-out of the obtained mixture in settlers, it is divided into a transparent liquid fraction and the sediment, i.e. an organomineral fertilizer. Afterwards, the fluid body is fed to irrigation of agricultural land, and its excess is discharged into waterways and reservoirs. The sediment is fed to the vortex layer equipment with mobile ferromagnetic particles or thermolized, where their complete disinfection takes place.

The research was carried out to determine the effect of different irrigation water requirements of different irrigation levels (mm), on the evapotranspiration seed yield (kg da-1) with vegetative and generative properties of two cotton types (drought tolerant, BA 525) and (drought susceptible, Lydia), in the Eastern Mediterranean region (Turkey). Drought or water deficit stress elicits many different phenological responses in plants. The study of vegetative features included the fresh and dry weight of plant (g), leaf area (cm2 ), number of leaves (number plant-1), number of fruit branches (number plant-1), number of bud formation (number plant-1) and number of node (number plant-1).This result indicates that water stress in plants limit the phenological development significantly and the average of all measurements made after flowering has been observed to decrease.

Opis:
The goal of this study is to determine the crop water stress index (CWSI) and irrigation scheduling based on CWSI values, as well as to examine the correlations between CWSI, physiological parameters and grain yield of hybrid corn P31A34 in semi-arid climate conditions. In 2014 and 2015, the upper limit (UL) temperatures at which plants were entirely exposed to water stress were 1.178°C and 2.38°C, respectively. When the corn grain yield began to decline, the CWSI threshold value was 0.34, indicating the yield limit. Grain yield, crop water consumption, crop water stress index, chlorophyll content, water use efficiency and leaf area index were found to have negative correlations (p ≤ 0.01) with CWSI values in both years of the study. The findings revealed that in semi-arid climate conditions, a maximum of 30% water deficit could be used during the growing period of the corn compared to full irrigation (I100) for water savings and that a water deficit greater than 30% results in considerable grain yield losses. In areas with limited water resources, the moderate water deficit (I70) may be a viable alternative to the I100.

Opis:
W doświadczeniach przeprowadzonych w latach 2005-2008 badano wpływ deszczowania i systemu uprawy (ekologicznego, integrowanego i konwencjonalnego) na plony i efekty ekonomiczne uprawy grochu siewnego. Stwierdzono większe przyrosty plonów nasion, białka w nasionach i ogółem w biomasie roślin w uprawie systemami integrowanym i konwencjonalnym, w porównaniu do ekologicznego, w warunkach deszczowania niż warunkach bez tego zabiegu. Deszczowanie, średnio dla systemów uprawy, zwiększyło plon nasion o 1,59 t/ha (119,5%), plon słomy o 0,80 t/ha (18,9%), plon białka w nasionach o 285,5 kg/ha (83,2%) i plon białka ogółem w nasionach i słomie o 303,9 kg/ha (43,4%). Plony nasion i ich białka w systemie integrowanym i konwencjonalnym były podobne i wyraźnie wyższe w porównaniu do systemu ekologicznego. W przypadku słomy plony przyrastały wraz ze zwiększaniem intensywności uprawy w systemach. Produktywność 1 mm wody z deszczowania była większa w systemach o wyższej intensywności uprawy. Deszczowanie obniżyło zawartość białka w nasionach i słomie. Najbardziej opłacalna, z uwzględnieniem dopłat odpowiednich dla systemów uprawy, w obu wariantach wodnych okazała się uprawa wg systemu ekologicznego. Deszczowanie, średnio dla systemów uprawnych, zwiększyło nadwyżkę bezpośrednią, bez pomniejszania jej o koszty zabiegu, o 1611,7 zł/ha.
In experiments carried out in 2005-2008 the influence of irrigation and cultivation system (organic, integrated and conventional), on the yields and economic effects of pea cultivation was investigated. It was stated larger increases of seed yield, protein in seeds and total protein yield in biomass of plants in integrated and conventional systems, in comparison with organic one, under irrigation conditions than under control conditions. Irrigation, on average for the cultivation systems, increased seed yield by 1,59 t/ha (119,5%), straw yield by 0.80 t/ha (18,9%), protein yield of seeds by 285,5 kg/ha (83,2%) and total protein yield of seeds and straw by 303,9 kg/ha (43,4%). Yields of seeds and their protein from integrated and conventional systems were similar and distinctly larger in comparison with organic one. In case of straw the yields increased with increasing of intensity in cultivation systems. Productivity of 1 mm of irrigation water was larger in systems of higher intensity of cultivation.. Irrigation decreased the protein content in seeds and straw. The most profitable, with taking into consideration adequate payments for systems, in both water variants turned out cultivation according organic system. Irrigation, on average for the cultivation systems, increased the direct surplus, without diminishing by irrigation cost, by 1611,7 PLN/ha.

Opis:
Uncertainties as to how the climate will change and how it will influence the necessities and trends of irrigation development lead to a number of serious questions to be answered in the near future. How irrigation and water systems will have to adapt to climate changes is a challenge that planners, designers and O&M services will have to cope with. It is widely accepted that air temperature in Poland will increase of 2-4°C, however a total yearly precipitation will not vary yet its pattern during the year may change towards higher in winter and lower in summer. Evapotranspiration and crop water demand may rise due to both an increase in temperature and duration of crop growth cycles. Three main factors are expected to exert an accelerating influence on the development of irrigation: increased frequency and intensity of droughts and long-lasting precipitation-free periods with the high insolation and high air temperatures resulting from climate change; the intensification of agricultural production (e.g. in horticulture, orchards, seed crops), being forced by both domestic and European free-market competition; the necessity of reaching high level of quality for the majority of agricultural products. To mitigate negative effects of climate change and extreme events, appropriate adaptation methods and adaptation strategies should be developed and implemented in existing irrigation and water control systems. A number of technological and organisational steps should be taken to improve operation, management, administration and decision making processes.
Zmiany klimatu będą wywierać silny wpływ na rolnictwo. Przeważa pogląd, że w skali ogólnej spodziewane zmiany, polegające na globalnym ociepleniu, przyniosą korzystne efekty w gospodarce rolnej, bowiem zwiększy się potencjał produkcyjny rolnictwa. W Polsce należy się spodziewać wzrostu temperatury o ok. 2-4°C. Konsekwencją tego wzrostu będą sezonowe zmiany ilościowe opadów atmosferycznych i natężenie ekstremalnych zjawisk pogodowych. Większość scenariuszy dla Polski nie przewiduje wzrostu sumy opadów w ciągu roku. Można natomiast spodziewać się wzrostu opadów zimowych, a zmniejszenia opadów letnich. Spowoduje to nadmierne uwilgotnienia gleby w okresie wczesnowiosennym i potrzebę odprowadzenia tej wody przez systemy drenarskie oraz przesuszenie gleb w okresie letnim i potrzebę nawodnień. Przewidywany wzrost natężenia i częstotliwości występowania susz może spowodować wzrost deficytów wody w rolnictwie. Susze stają się w ostatnich latach coraz bardziej dokuczliwe, a przesuszenie wielu obszarów jest wyraźne. Jednocześnie dopuszcza się do bardzo głębokiego kryzysu nawodnień w Polsce. Obecnie nawodnienia w Polsce odgrywają znikomą rolę zarówno w produkcji rolnej, jak i gospodarce wodnej. Są stosowane zaledwie na ok. 0,5% powierzchni użytków rolnych (łącznie wszystkie rodzaje nawodnień). Możliwe zwiększenie deficytów wody w rolnictwie w wyniku zmian klimatu może utrwalić obecne trendy rozwoju nawodnień. Znaczenie nawodnień w polskim rolnictwie powinno się zwiększać wraz z intensyfikacją rolnictwa i negatywnymi skutkami zmian klimatu.

Opis:
Participatory monitoring allows communities to understand the use and management of local water resources and at the same time develop a sense of ownership of environmental information. The data generated through participatory monitoring of stream flow and rainfall generate evidences to corroborate local people’s experiences with changing water resources patterns. In this study we evaluate the potential of participatory monitoring of hydrological variables to improve scarce water supply utilization in agriculture. The case study site is the Mustang district in Nepal, which is located in the Upper Kaligandaki River Basin in the Himalayas with unique and complex geographical and climatic features. This region is characterized by a semi-arid climate with total annual precipitation of less than 300 mm. Water supply, agricultural land, and livestock grazing are the key ecosystem services that underpin livelihood security of the local population, particularly socio-economically vulnerable groups. An analysis of the measured stream flow data indicate that annual flow of water in the stream can meet the current crop irrigation water needs for the agricultural land of the research site. The data provide local farmers a new way of understanding local water needs. Participatory monitoring would contribute to an optimization of the use of ecosystem services to support economic development and livelihood improvement.

Opis:
In the Hassi Messaoud region, is groundwater the only source of water to meet daily demands, especially for consumption, domestic needs, industry and irrigation. This study focused on the evaluation of groundwater quality for potability and irrigation supply and the understanding of mineralization processes in the Mio-Pliocene (CTM), Senonian (CTS) and continental intercalary (CI) aquifers. For this study, 38 boreholes were sampled and analyzed for different parameters: pH, EC, TDS and major ions. The assessment of the relevance of groundwater in the study area was tested by the application of the water quality index (WQI) method. The suitability of the water for agricultural use was tested using the parameters of; EC, SAR, Na%, KR, PI and MH. The results illustrate that the groundwater in the study area is grouped into three classes: poor, very poor and unsuitable. Regarding groundwater use in irrigation, the results indicate that the waters of Hassi Messaoud are unsuitable for irrigation according on the EC and Wilcox diagram. The groundwater of the investigated area presents two types of water; Ca-Mg-HCO3 and Ca-Mg-HCO3. The study of the mineralization process of water using the Gibbs diagram and binary diagrams and the indices of saturation showed that the mineralization of water is controlled by the dissolution of evaporites and carbonates, silicate weathering and cation exchange. The participation of anthropic contributions is also noted in the Mio-Pliocene aquifer.

Opis:
Groundwater is vital for all living beings and the socio-economic development of arid regions. The present study evaluated the pertinence of groundwater of the continental intercalary (CI) aquifer in the Ouargla region for domestic and agricultural purposes. Sixteen (16) water samples were collected and analyzed for physical parameters, major cations and anions. The appreciation of groundwater potability was compared with the WHO (2017) standards. Agricultural water quality was evaluated using the Irrigation Water Quality Index (IWQI) method and the study of irrigation parameters: EC, SAR, SSP, PI, KR, PS and MAR. The results show that the CI waters are dominated by mixed Ca-Mg-Cl type (56.3%) and Ca-Cl type (43.7%). Natural rock-water interactions, including silicate weathering, evaporite dissolution and cation exchange, were the dominant processes controlling the mineralization of CI waters. According to WHO (2017), EC (100%), T (100%), TDS (100%), Na+ (87.5%), K+ (100%), Ca2+ (12.5%), Mg2+ (18.75%), SO42- (100%), and TH (100%), samples exceed the permissible limit, indicating that most of the groundwater samples do not have good quality for drinking purposes. The calculated IWQI showed that 31.25% of the water samples were in the good category and 68.75% in the doubtful category.

The field experiment was carried out in 2004-2006 in Chlebówko localized 20 km from Stargard Szczeciński and 5 km north-east from Stara Dąbrowa commune - 53°27’N and 15°10’E. The area is elevated 62-72 m above mean se level (ASL). The influence of irrigation, tillage system, and NPK mineral nutrition on weed infestation of faba bean variety ‘Titus’ with determined development rate, was evaluated. The weed infestation degree in the faba bean plantation depended on moisture conditions, fertilization rates, and tillage system. Irrigation increased the number, fresh weight, and dry matter of weeds, respectively by 92%, 130%, and 138%. Likewise, increasing nutrition elevated values of these parameters by 46%, 80%, and 95%. The tillage simplifications enhanced the weed population, particularly on irrigated and fertilized objects. Irrigation, mineral nutrition, and simplified tillage caused compensation of spring, winter and perennial weed species on plantation of faba bean ‘Titus’. Chenopodium album, Stellaria media, and Polygonum convolvulus predominated on studied plots.

Opis:
Polska jest największym producentem jabłek w Europie. Opady atmosferyczne są podstawowym źródłem wody dla roślin. Klimat Polski charakteryzuje przestrzenna i czasowa zmienność, co utrudnia szacowanie potrzeb nawodnieniowych roślin oraz prognozowanie bilansu wodnego. Celem podjętych badań była ocena potrzeb wodnych jabłoni oraz wysokości opadów efektywnych co pozwoli na określenie potrzeb nawadniania. Dane pomiarowe obejmowały okresy wegetacyjne od V do IX za lata 2011-2016. Analizując dane średnie dla lat i lokalizacji badań stwierdzono, że w naszych warunkach klimatyczny bilans wodny (KBW) tylko w czerwcu dokładnie odzwierciedla bilans potrzeb wodnych jabłoni. W maju wartości KBW są wyraźnie zawyżone w odniesieniu do bilansu potrzeb wodnych jabłoni (BPW-jabłoni), a w VII, VIII i IX zaniżone.
Poland is the biggest producer of apple in Europe. Rainfalls are basic source of water for plants. The climate of Poland is characterized by high temporal and spatial variation that makes estimation of plant water requirements and forecasting of water balance difficult. The aim of the study was assessment of water needs of apple trees as well as amount of effective precipitation, enabling estimation of irrigation requirements. Data was collected during vegetative periods (May - Sep.) of 2011-2016. Analysis of data from different years and locations revealed that in Polish conditions climatic water balance accurately reflects balance of water requirements of apple trees only in June. In May values of climatic water balance were significantly higher, whereas in July, August and September lower compared to balance of apple water requirements.

The aim of this study was to investigate the effects that supplemental irrigation (SI) has on the Kale (Brassica Oleracea) crop yields as compared to the wholly rain-fed crop. The experiments were conducted in Kieni, Central Kenya where the rainfall pattern was bimodal. The planting for rain-fed crops was done in three blocks, each measuring 10×1 m with a spacing of 30 cm between plants and 45 cm between the rows of plants; the procedure was repeated for the crops receiving SI. The average weekly yields were computed for both crops for each season comprised of 14 weeks. The average weekly yields were subjected to Analysis of Variance (ANOVA) to determine whether the average yields from the rain-fed and supplemental irrigated crops were statistically different. This was done with MS Excel 2016 spread sheets by setting a statistical level of significance of 5%. The F value was 17.94 higher than the critical value of 4.01 while the P-value of 9×10–5 was lower than the 5% level of confidence meaning that there was a significant difference in the yield means of the rain-fed and SI crops. The total rain-fed crop yields for the period was 147.0 Kgs and that of the one under SI was 238 Kgs, an increase of about 62%. Therefore, supplemental irrigation can be adopted in the areas where rainfall trends are declining to increase the crop yields when all other factors remain constant for farmers – to increase resilience.

На основании данных статистических ежегодников за 1983-1985 г. охватывающих урожаи 4-х хлебов, картофеля и сахарной свёклы в пересчете на зерновые культуры, а также разработанных Институтом агротехники, удобрени и почвоведения показателей валоризации сельскохозяйственной производственной площади, были сравнены, с помощью расчетных показателей использования естественной производственности четырёх выбранных макрорайонов: северного, средне-западного, средне-южного и средне-восточного. Разницы использования естественной производственности между сравниваемыми макрорайонами достигают 21,1%, а в заготовке сельскохозяйственных продуктов - 50%. О том решают организационные и техническо-ресурсные факторы. В условиях небольшого использования естественной производственности дождевальные установки могут быть заменены другими, неинвестиционными и более дешевыми средствами. Капиталовложения, понесённые на оросительную инвестицию, были бы тогда нерентабельными. Таким образом районирование орошений не может основываться исключительно на естественно-почвенных и климатических критериях. Должна быть проверена верность оценки использования сельскохозяйственной производственной площади, как в макро, так и микромасштабе.
The natural productivity of four selected regions, viz.: northern, central-western, central-southern and central-eastern one, was compared on the basis of the data of statistical yearbooks for the period 1983-1985 comprising the yields of 4 cereals, potatoes and sugar beets as well as of the indices of valuation rate of particular agriculture production areas worked out by the Institute of Soil Science and Cultivation of Plants. The differences in the natural productivity utilization between the macroregions compared reached 21,1% and in the purchase of agricultur products - 50%. This depended on the factors of organization and technical resources. The sprinkler irrigation systems can be replaced under conditions of low natural productivity by other, smaller and cheaper production means. Expenditures for the irrigation investments would be unprofitable in this case. The irrigation regionalization cannot thus be based exclusively on natural soil and climate conditions. The estimation correctness of the agricultural production area should be verified both in macro- and microscale.

W pracy zaprezentowano ocenę ekonomiczno-finansowej efektywności kroplowego nawadniania wiśni w trzech gospodarstwach sadowniczych, z których dwa położone są w powiecie grójeckim (woj. mazowieckie), a jedno w powiecie Lipno (woj. kujawsko-pomorskie). Badania polegały na rejestracji danych o plonach na polu nawadnianym i bez nawodnień, przychodów z ich sprzedaży oraz kosztach nawodnień. Na podstawie zgromadzonych informacji obliczono zwyżki plonów na skutek nawodnień oraz obliczono wskaźniki ekonomiczno-finansowej efektywności nawadniania. Wskaźniki efektywności zostały obliczone metodą zdyskontowanych przepływów pieniężnych. Badania wykazały, że średnia zwyżka plonów na skutek nawodnień wyniosła 2,07 t∙ha-1 (20%), a w poszczególnych gospodarstwach w granicach 1,6‒2,6 t∙ha-1 (11‒29%). Nawodnienia wiśni były ekonomicznie uzasadnione, ponieważ finansowa aktualna wartość netto przedsięwzięcia w poszczególnych gospodarstwach (FNPV), w warunkach stopy dyskontowej r = 6%, wynosiła w granicach 7,91‒35,36 tys. zł, a finansowa wewnętrzna stopa zwrotu z inwestycji (FRR) od 15,2%, do 51,3%. Wskaźniki FRR są zdecydowanie wyższe niż stopa inflacji i oprocentowanie lokat bankowych w okresie badań, jednak niższe niż uzyskane w innych badaniach dotyczących nawadniania sadów jabłoniowych, truskawek, warzyw i ziemniaków jadalnych.
The paper presents an assessment of the economic and financial efficiency of drip irrigation cherry orchard in the three farms. Two of which are located in the district of Grójec (Mazowieckie province) and one in the district of Lipno (Kujawsko-Pomorskie province). The study relied on data relating to the yield on a field irrigated and without irrigation, revenues from the sale and irrigation costs. On the basis of collected data, the crop yields increases and indicators of economic and financial efficiency due to irrigation was calculated. Indicators of economic and financial efficiency were calculated using the discounted cash flow method. Studies have shown that the average increases yields through irrigation was 2.07 t∙ha-1 (20%) and individual farms within 1.6–2.6 t∙ha-1 (11–29%). It should be noted that the irrigation of cherries orchard have been economically justified because the financial net present value of the project on individual holdings (FNPV), under the conditions of the discount rate r = 6%, was in the range 7.91–35.36 thousand zł, a financial internal rate of return (FRR) from 15.2% to 51.3%. Indicators FRR much higher than the rate of inflation and interest rates on bank deposits during the study period, but lower than those obtained in other studies on the irrigation of apple orchards, strawberries, vegetables and potatoes.

Opis:
Polish water resources depend on precipitations, which are variable in time and space. In dry years the water balance is negative in central parts of Poland but sudden thaws and downfalls may result in periodical water excess and dangerous floods almost in the entire country. The retention capacity of artificial reservoirs in Poland permits to store only 6% of the average annual runoff, which is commonly considered insufficient. Another method to increase retention is soil water control. About fifty percent of soils in Poland consist of light and very light sandy soils with low water capacity. Loams and organogenic soils cover approximately 25% and 8.5% area of the country, respectively. Almost half of agricultural lands (48%) have relatively good water conditions, but the rest requires soil water control measures. An increase of the soil water content could be achieved by changes of soil properties, water table control and soil water management. Modernization and reconstruction of drainage and irrigation systems, which were built mainly in the period 1960-1980, is needed.
W pracy scharakteryzowano główne problemy związane z zasobami wodnymi w Polsce oraz koniecznością regulacji stosunków wodnych na obszarach rolniczych i leśnych. Problemy ilościowe gospodarki wodnej w Polsce, związane z występowaniem trwałych lub okresowych deficytów względnie nadmiarów wody, są skutkiem zmienności czasowo-przestrzennej opadów atmosferycznych oraz stanu infrastruktury wodnej. Opady charakteryzują się dużą zmiennością zarówno w okresach wieloletnich, jak i w ciągu roku. Sumy średnich opadów rocznych w latach mokrych mogą być ponad 2-krotnie większe od opadów w latach suchych. Częstym zjawiskiem jest występowanie susz, powodujących klęski nieurodzaju, wzrost zagrożenia pożarowego lasów, wysychanie studni itp. Zróżnicowanie przestrzenne opadów natomiast sprawia, że w centralnej części Polski bilans wodny, zwłaszcza w latach suchszych, jest ujemny. Z drugiej zaś strony gwałtowne roztopy i zjawiska ekstremalne w postaci opadów nawalnych powodują okresowe nadmiary wód i powodzie. Z tych niekorzystnych zjawisk wynikają podstawowe zadania gospodarki wodnej na terenach niezurbanizowanych, do których należą: zapewnienie zaopatrzenia w wodę ludności i poszczególnych gałęzi gospodarki narodowej, ochrona przed powodzią, regulacja stosunków wodnych na obszarach użytkowanych rolniczo, zapewnienie trwałości ekosystemów przyrodniczych, w tym lasów. Wyrównanie okresowych braków lub nadmiarów wody osiąga się w różny sposób, generalnie poprzez zmagazynowanie wody w zbiornikach powierzchniowych naturalnych i sztucznych, a także w glebie i w podziemnych warstwach wodonośnych. Pojemność retencyjna sztucznych zbiorników wodnych w Polsce umożliwia zmagazynowanie jedynie 6% średniego rocznego odpływu i jest powszechnie uznawana za niewystarczającą. Obieg wody w zlewniach, zdolności produkcyjne gleb, a także szkody erozyjne zależą w dużej mierze od urządzeń melioracji szczegółowych. Obecnie ponad 20% wykonanych urządzeń w okresie powojennym uległo dekapitalizacji i przy obecnym poziomie inwestycji w najbliższych 10 latach osiągnie wielkość około 30%. Oznacza to znaczne ograniczenie wykorzystania potencjalnych zdolności produkcyjnych gleb oraz powiększanie strat w okresach ekstremalnych, zarówno susz, jak i powodzi. Jest to jedno z większych zagrożeń racjonalnej gospodarki wodnej na obszarach rolnych i leśnych. W dużym stopniu, zarówno na terenach rolniczych, jak i leśnych, są one zużyte i wymagają odbudowy, a najczęściej modernizacji. W pracy podkreślono konieczność uwzględniania wymogów ochrony zasobów wodnych i pozostałych elementów środowiska i to zarówno w fazie projektowania urządzeń melioracyjnych, jak i ich eksploatacji.

In the article presented the features of application and adaptation of the calculation method for determination of evapotranspiration Penman–Monteith. With the purpose of effective use of this method in the practice of a drip irrigation in the steppe zone of Ukraine, on the base of the field’s experiments results were conducted correlation of Kc with a taking into account deviations from standard conditions (on the example of grain corn).
Celem badań prezentowanych w pracy była analiza specyfiki ewapotranspiracji i adaptacja obliczeniowej metody Penmana-Monteitha do określania tego parametru w warunkach stepu Ukrainy. Prowadzono krótkotrwałe doświadczenia polowe, wykorzystując ogólnie stosowane analizy statystyczne: dyspersji, korelacji, regresji i wariancji. W pracy określono wartość ewapotranspiracji obliczeniowej ЕТо i rzeczywistej ЕТс, wykorzystując do tego nowoczesne narzędzia (internetowa stacja meteo iMetos® i stacja pomiaru wilgotności gruntu iMetos® SM/ECHO/TNS/ECOD2). Na podstawie eksperymentu polowego skorygowano współczynnik roślinny Kс w zależności od fazy rozwoju roślin kukurydzy. Ustalono, że wartości rzeczywistego współczynnika roślinnego Kс kukurydzy uprawianej na ziarno w warunkach nawadniania kroplowego na stepach Ukrainy różnią się od Kc podawanego przez FAO. W początkowych i końcowych fazach rozwoju kukurydzy wartość Kc (FAO) zawyża wartość ewapotranspiracji rzeczywistej od 20 do 225%, a w połowie sezonu – zaniża o 10–15%. Ze względu na wyraźną korelację Kc (FАО) і Kc(ac.) do wyznaczenia ewapotranspiracji rzeczywistej (ЕТс) kukurydzy autorzy rekomendują stosowanie skorygowanej wartości Kс.

Opis:
Drought is characterised as a recurring climatic phenomenon with prolonged duration, affecting land through below-average rainfall and often accompanied by high temperatures. When the available water falls below the optimum level, water deficit or water stress arises, disrupting normal plant processes. This condition poses challenges for plant growth and development as it hampers the internal water transport, induces stomatal closure, and limits access to photosynthetic resources. The study employed the annual sunflower as the experimental plant. The plants were cultivated in a controlled environment with a temperature ranging from 20 to 25°C and a humidity level of 55 to 60%, supplemented by MARS HYDRO artificial LED lighting set to a 12-h photoperiod. Radial changes in the plant stems were monitored using a DD-S type dendrometric sensor to measure radial fluctuations. The collected data were recorded in a dendrometric data logger DL 18. Data collection occurred at hourly intervals from February 20 to March 9, 2023. The nine plants were divided into three groups, each comprising three plants. All plants from groups 1 and 2 received irrigation at one-day intervals (group 1 - 80 cm3 per plant, group 2 - 40 cm3 per plant) and group 3 was not irrigated. Based on these findings, visible water stress was evident in the plants under experimental conditions. Consequently, continuous monitoring throughout the growing season will be essential to adjust the irrigation rate to meet the requirements of the plants.

The present study aims at evaluating the quality of shallow groundwater (SGW) and its suitability for irrigation purpose in the most urbanised part of Johannesburg city, South Africa. The SGW samples were collected in three consecutive years and analysed for 20 selected physicochemical parameters, and heavy metals. The results were compared with the South African water quality, and Food and Agricultural Organization irrigation water quality guidelines, and standard indices derived from laboratory outputs. The results of the study show that all physiochemical parameters and heavy metals were within the limits set by both guidelines for irrigation purposes, except for potassium (3.58 mg∙dm-3) and manganese levels (3.152 mg∙dm-3). The calculated irrigation parameter values of sodium adsorption ratio (SAR), sodium percentage (Na%), residual sodium carbonate (RSC), magnesium hazard (MH), Kelly’s ratio (KR) and permeability index (PI) were within the permissible range of irrigation water quality standards. The findings of this study provide helpful information for decision-makers such as utilisation of the studied groundwater for irrigation uses.

Opis:
Water is a sensitive and limited resource, mainly in intensively used agricultural areas in Austria , where groundwater is used as drinking water as well as for irrigation purposes. In order to guarantee a sustainable use of irrigation water, soil water measurement devices can be used to optimise irrigation, which means that controlling the soil water content in the entire root system may prevent water stress due to water deficiency on the one hand, and over wetting on the other hand. Furthermore, losses of nutrients due to leaching can be avoided. Several research studies on that topic were initiated during the last few years. The soil water status on selected fields planted with different crops (onions, carrots, sugar beets, sweet maize, zucchini) was monitored continuously by FDR (Frequency Domain Reflectometry) soil water measurement devices. Sensors in different depths measure the plant water uptake in the root zone under standard irrigation practices on different sites and different soils, respectively. The deepest sensor is installed to avoid deep percolation caused by over irrigation. By means of these data, irrigation could be regulated based on the actual plant water requirements to keep the soil water content within an ideal range for crop development.
W pracy omówiono tematykę ciągłego pomiaru uwilgotnienia gleby z wykorzystaniem najnowszej technologii informatycznej. Podano zarówno podstawy teoretyczne, jak też zagadnienia praktyczne. Opisana technologia polega na zastosowaniu reflektometrów w domenie częstotliwości FDR - wilgotnościomierzy wykorzystujących pomiar pojemności elektrycznej. Urządzenie to umożliwia sterowanie nawodnieniami oraz ciągłe monitorowanie ilości wody magazynowanej w danym czasie w profilu glebowym na określonej głębokości (zasięg 0-80 cm). Przedstawiono wieloletnie wyniki doświadczeń polowych w Austrii, uzyskane na obiektach, na których stosowano metodę sterowania nawodnieniami upraw polowych oraz warzyw w latach 2001-2006. Omówiono dwa różne systemy monitorowania wilgotności gleby w celu sterowania nawodnieniami: Sentek EnviroScan: dane mogą być ładowane w trybie odbioru (do własnego komputera) lub przez modem GSM - ten system wykorzystano w uprawie cebuli, cukinii, kukurydzy pastewnej, marchwi oraz buraków cukrowych; Przekaźnik typu Adcon - zastosowany w uprawie ziemniaków, buraków cukrowych, cebuli, marchwi drobnej oraz fasoli, z czujnikami EasyAG-Sentek umieszczonymi na głębokości 10, 20, 30 i 50 cm. Badania udowodniły, że można zmniejszyć straty wody w nawodnieniach rolniczych dzięki ciągłemu monitorowaniu uwilgotnienia gleby na kilku głębokościach.

Efforts on the management of water resources, especially irrigation and drainage, in arid-semiarid areas are extremely important for the sustainability of irrigated agriculture. Groundwater level should be constantly monitored and kept at the desired level in the project which is achieve the expected benefits from investments made for this goal. The research was done in right bank irrigation area which is located in Southeast Turkey, Suruc Plain in 2017. The spatial and temporal fluctuations of the groundwater table depth and groundwater salinity were measured in the course of five-month-periods; from July to October. The results of depth (m) and salinity (µmhos cm-1) of the groundwater observation wells were mapped using geographical information system (GIS). The results showed that groundwater was not found in many observation wells, while groundwater depth reached to a critical threshold level (2 m (risk free for drainage) from July to October in the study area. The groundwater salinity was found to be less than 2250 µmhos cm-1 at the research area. Depending on the research findings, it was noted that there were not any waterlogging, drainage and salinity problems stemming from the rise of groundwater table due to short-term irrigated agriculture in the plain.

Opis:
Spring frost in the blooming time can be a significant factor decreasing the fruit production and affects the cultivation profitability in the years with unfavourable weather conditions. In Poland, the fruit trees especially susceptible to damage are peach and apricot trees. Among the popular methods of protecting the trees against spring frost damage there are three kinds of treatment: sprinkling irrigation, fogging, smoking and using fans for mixing the layers of air. The costs of applying the particular methods differ, as well as their efficiency. The side effect of using them can be also orchard pollution. The experiment was conducted on selected peach tree cultivars, on two rootstocks. Two methods of spring frost protection were applied: sprinkling irrigation and fogging with the use of glycerin mixed with tap water in proportion 1:10. Sprinkling irrigation proved to be more effective, it protected 98% of blooms. Using the fogging device also brought a satisfying effect. The cultivars that were easily damaged by spring frost were ‘Early Redhaven’ and ‘Cresthaven’. The greatest resistance to bloom damage was observed in the case of the ‘Suncrest’ and ‘Saturn’ trees. The yielding of the ‘Inka’ and ‘Early Redhaven’ trees protected by sprinkling irrigation was significantly better, as compared with the fogged trees. The mean fruit weight was determined mainly by the cultivar.

Opis:
The margins of the oases of the Mendoza province have acquired in the last two decades special relevance as a focus of investment of the so-called “agribusiness model.”  The latter has been the protagonist of a real conquest in peripheral areas of the oasis, expanding the agricultural frontier based on the acquisition of land selected for its edaphic characteristics, the exploitation of groundwater, and the application of modern irrigation systems. Starting with the so-called new vitiviniculture –characterized by the production of high-quality wine destined for export–this dynamic was also evident in other fruit or horticultural sectors. In this article, from a vertical and multidimensional perspective, we analyze the processes that enable control over certain rural spaces and their water resources by agribusiness corporations located on the margins of the Uco Valley oasis. We argue that a singular logic of production-consumption underlies these grabbing processes. Firstly, we argue that this logic works in several practices of precision agriculture, and we will give an account of the relationship between the expanding of peripheral lands for agro-productive purposes, the implementation of technologies to irrigate and put them into production, and the targeted markets. We will focus more specifically on vitivinicultural projects and agro-industrial potatoes production. Secondly, we argue that this logic also operates in relation to the growing conversion of new productive rural spaces into enclaves of tourist and real estate consumption, related to viticulture.
Los márgenes de los oasis de la provincia de Mendoza adquirieron estas últimas décadas especial relevancia como focos de inversiones del modelo de agronegocios. Éste se destacó como el protagonista de una verdadera conquista en zonas periféricas de los oasis, expandiendo la frontera agrícola en base la adquisición de terrenos seleccionados por sus características edáficas, la explotación de aguas subterráneas y la aplicación de modernos sistemas de riego. Protagonizada por la llamada nueva vitivinicultura -caracterizada por la producción de vinos de alta calidad enológica y orientada al mercado internacional- esta dinámica se evidenció también en otros sectores frutícolas u hortícolas. En este artículo indagamos, desde una mirada vertical y pluridimensional, acerca de los procesos que rigen el control sobre determinados espacios rurales y sus recursos hídricos por parte de organizaciones empresariales, ubicadas en los márgenes del oasis del Valle de Uco. Argumentamos que una singular lógica de producción-consumo subyace en estos procesos de acaparamiento. Por un lado, defendemos que esta lógica opera en varias prácticas de agricultura de precisión y buscaremos dar cuenta de la relación que se establece entre los acaparamientos de tierras periféricas con fines agro-productivos, la implementación de tecnologías para irrigarlas y ponerlas en producción, y los mercados de destino. Nos centraremos más específicamente sobre proyectos vitivinícolas y paperos agroindustriales. Por otro lado, defendemos que esta lógica opera también en relación a la creciente conversión de nuevos espacios rurales productivos en enclaves de consumo turístico e inmobiliario, relacionados a la vitivinicultura.

The field experiment with three species of grasses in different water conditions was carried out in 2005-2008 in the experimental fields in Złotniki near Poznan, a subsidiary of Experimental- Educational Laboratory for Soil and Plant Cultivation, University of Life Sciences in Poznan. The aim of the study was to elaborate a nitrogen balance, using common indicators of uptake and based on laboratory confirmed nitrogen content in plant material. On this basis, both developed balances were confronted. In conducted study it was found that the calculation of the amount of nitrogen taken with the use of generally accepted factors was understated in relation to the actual uptake. In the option with sprinkling irrigation, regardless of species, the applied dose of 180 kg of nitrogen was almost entirely used by plants, but in the option without sprinkling irrigation, nitrogen balance was obtained after the application of about 120 kg N ha-1.
Doświadczenie polowe, z trzema gatunkami traw w zróżnicowanych warunkach wodnych: w wariancie deszczowanym i niedeszczowanym, przeprowadzono w latach 2005-2008 na polach doświadczalnych w Złotnikach koło Poznania, filii Zakładu Doświadczalno-Dydaktycznego Uprawy Roli i Roślin Uniwersytetu Przyrodniczego w Poznaniu. Celem przeprowadzonych badań było opracowanie bilansu azotu, z wykorzystaniem powszechnie stosowanych wskaźników pobrania oraz na podstawie zawartości azotu w materiale roślinnym oznaczonej laboratoryjnie. Na tej podstawie skonfrontowano obydwa opracowywane bilanse. W przeprowadzonych badaniach stwierdzono, że obliczenie ilości pobranego azotu przy pomocy powszechnie przyjętych współczynników było zaniżone w stosunku do pobrania rzeczywistego. W wariancie deszczowanym, niezależnie od gatunku, zastosowana dawka 180 kg azotu, praktycznie w całości została wykorzystana przez rośliny, natomiast w niedeszczowanym, zbilansowanie azotu uzyskiwano po zastosowaniu około 120 kg N ha-1.

Opis:
Ściółkowanie gleby, dość często stosowane w uprawie polowej różnych gatunków warzyw, jest korzystnym zabiegiem produkcyjnym, gdyż stwarza odpowiednie warunki glebowe dla wzrostu uprawianego gatunku. Celem badań przeprowadzonych w latach 2011-2012 było ustalenie wpływu kilku rodzajów ściółek oraz nawadniania kroplowego na plonowanie selera korzeniowego. Doświadczenia zostały przeprowadzone na certyfikowanym polu ekologicznym Instytutu Ogrodnictwa. W doświadczeniu stosowano ściółkowanie włókniną biodegradowalną, włókniną biodegradowalną z dodatkiem suszu z koniczyny, włókniną polipropylenową (w 2012 roku ściółkę z czarnej włókniny zamieniono na ściółkę biodegradowalną z dodatkiem suszu z lucerny) oraz świeżą koniczyną. Kontrolę dla stosowanych ściółek stanowiły poletka bez okrycia gleby. Badania prowadzono w warunkach nawadniania kroplowego oraz bez nawadniania. W obu latach badań na obiektach nawadnianych kroplowo plon handlowy był większy w porównaniu do obiektów nienawadnianych odpowiednio o 15,5% w 2011 roku i o około 13,7% w 2012 roku. Największy wpływ na plonowanie w obu latach badań miała ściółka ze świeżej koniczyny. Plon handlowy uzyskany z poletek ściółkowanych koniczyną czerwoną był wyższy w stosunku do poletek kontrolnych o około 21% w 2011 r. i o około 18,2% w 2012 r. Różnic statystycznych pomiędzy pozostałymi ściółkami nie wykazano. Stwierdzono natomiast istotny wpływ każdej z zastosowanych ściółek na plonowanie względem kontroli. W obydwu latach badań nie stwierdzono istotnego współdziałania pomiędzy zastosowaną ściółkowaniem a nawadnianiem. Zarówno w 2011, jak i 2012 roku udział korzeni o średnicy >13 cm w plonie handlowym był wyższy na poletkach nawadnianych w porównaniu do kombinacji nie nawadnianej. Zwiększony udział korzeni o średnicy >13 cm w plonie handlowym w porównaniu do kontroli stwierdzono również po zastosowaniu każdej ze ściółek.
Mulching the soil, is often used in the field production of vegetables, as it creates the right conditions for the growth of soil cultivated species. The aim of the experiment carried out in 2011-2012 was to determine the impact of several types of mulches and drip irrigation on the yield of celeriac. Experiments were conducted on certified organic field of the Institute of Horticulture. In the experiment biodegradable fleece, biodegradable fleece with dried clover, black polypropylene fleece (in 2012, a black polypropylene turned into biodegradable fleece with the addition of dried alfalfa) and fresh clover mulches were used. Plots without cover soil were control for use mulches. The study was conducted in a drip irrigation and without irrigation. In the two years of research the drip irrigation increased marketable yield compared to non-irrigated, by 15.5% in 2011 and about 13.7% in 2012. The highest influence on yield in both years of the study showed a mulch of fresh clover. Marketable yield obtained from plots mulched with red clover was higher in comparison to control plots by about 21% in 2011 and about 18.2% in 2012.The statistical differences between the other mulches not occur. However there was a significant effect of each of the applied mulches on the yield increase in relation to the control treatment. In both years of the study there was no significant interaction between mulching and irrigation applied. Both in 2011 and 2012 share of roots with diameter > 13 cm in the marketable yield was higher on irrigated plots, in comparison to a combination of not irrigated. Increased share of root with diameter > 13 cm in the marketable yield in comparison to the control was also found after the application of each mulch.

Opis:
The paper includes a detailed water need forecasting analysis of fruit plants: apple trees, pear trees, cherry trees and plum trees, for the area of Poland with particular water deficits. The assessment was carried out for the multiannual period of 1989-2018, using three methods developed by Press, Grabarczyk and Rzekanowski, and Treder. The greatest water needs in the multiannual period (1989-2018) were demonstrated by apple and plum trees. The average water needs of apple trees in the multiannual period were 485 mm (Press method), 599 mm (Rzekanowski and Grabarczyk) and 558 mm (Treder), respectively. The average amount of water needs of plum trees was 506 mm (according to Press), 590 mm (Rzekanowski and Grabarczyk) and 548 mm (Treder). In practice, each of the methods presented should be used to forecast the water needs of fruit plants. This will minimise the risk of water shortages and will also enable determination of irrigation doses.

Opis:
The final success and outcomes of patients treatment undergoing Functional Endoscopic Sinus Surgery depends on the correct preparation for surgery, perioperative and postoperative care. Proceedings before FESS in case of chronic rhinosinusitis arise from „European position paper on rhinosinusitis and nasal polyps 2012” and includes pretreatment with local nasal and systemic steroids, sinus irrigation, as well as in some cases antibiotic therapy. Reduction of intra- and post-operative bleeding is possible by intraoperative use of gauze local vasoconstricting inserts, reverse Trendelenburg position, reduction of blood pressure and application of tranexamic acid. After the surgery the use of nasal packing is often recommended. Moreover postoperative care has been largely transferred to the patient and therefore we are highlighting how important is education of patient, providing accurate information and training in the appropriate use of prescribed preparations for na-posal irrigation and nasal steroids. The use of steroids was proved to reduce the risk of recurrence of the disease and it is reasonable when we are sure that they have an opportunity to reach physically to whole mucous membrane of the nose. The effectiveness of nasal irrigation can be enhanced by use of the containers enabling the appropriate application (the exact adherence to the nasal vestibule , at an angle 45° ) and generating sufficient pressure ( rinse of the entire nasal cavity –120 mbar) and the use of appropriate fluid composition accelerates healing and reduce pain. Use of in vitro studies and computational fluid dynamics simulations allow to predict the effectiveness of rinsing different paranasal sinuses.

Opis:
The aim of the research was to evaluate the effect and interaction of sprinkler irrigation and nitrogen fertilisation on the grain yield and baking value of ‘Monsun’ spring wheat cultivar grown in light compacted soil. A field experiment was performed in 2013-2014 in an experimental field of the Department of Land Improvement and Agrometeorology, the UTP University of Science and Technology, at Mochełek, in the vicinity of Bydgoszcz. It was found that sprinkler irrigation significantly increased the spring wheat grain yield. The grain from sprinkler-irrigated stands demonstrated greater plumpness; it contained significantly less protein and gluten and showed a lower sedimentation value, as compared with the grain of non-sprinkler-irrigated plants. However, the protein yield produced under sprinkler irrigation conditions was on average 11% higher, compared to the control conditions. The effect of nitrogen fertilisation on the spring wheat grain yield and quality corre¬spond to earlier findings. Similarly to other research reports, a regular yield increase and enhanced quality of baking features along with an increase in the nitrogen rate were identified. Considering the quantitative and baking features of the grain yield, it was found that the optima nitrogen fertilisation rate in ‘Monsun’ spring wheat, in both water variants, was 180 kg.ha-1 (pre-sowing 120 kg .ha-1 and top dressing 60 kg ha-1).
