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 paper presents results of a controlled field experiment with sprinkler irrigation of winter oilseed rape (Latin name) cv. Arsenal F1 Linagrain and winter wheat (Latin name) cv. 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:
Cucumber is one of the most popular vegetables in Poland. This vegetable species is characterised by high requirements in terms of soil temperature and moisture. The utilization of polyethylene mulch in combination with drip irrigation has played a major role in the increases in production of cucumber. The benefits associated with the use of this cultivation method include earlier and higher yields, reduced soil evaporation, reduced weed populations, reduced fertilizer leaching, greater water use efficiency, reduced soil compaction, control of certain pests, and cleaner harvested product. In years 2002, 2003 and 2005 experiments were conducted to study the impact of soil mulching with black polyethylene on Akord F1 cucumber yields. Plants were cultivated on sandy loam soil using irrigation and fertigation applied with the assistance of drip lines. No significant differences were observed in levels of total and marketable yields of fruits as well as in dry matter and total carbohydrate contents in fruits obtained from plants cultivated in mulched and unmulched soils. Irrigation efficiency, on the soil mulched with black polyethylene was higher than on the soil without mulching.
Ogórek jest jednym z najbardziej popularnych warzyw w Polsce. Gatunek ten charakteryzuje się między innymi wysokimi wymaganiami w stosunku do temperatury i wilgotności gleby. Ściółkowanie gleby w połączeniu z nawadnianiem kroplowym może być dobrym rozwiązaniem dla spełnienia tych wymagań. Korzyści wynikające z takiego sposobu uprawy to: wcześniejszy i większy plon, zmniejszone parowanie gleby i wymywanie składników pokarmowych, a co za tym idzie – większa efektywność nawadniania i nawożenia, mniej chwastów na plantacji, mniejsze zbicie gleby, możliwość zmniejszenia stosowania pestycydów i czystsze produkty. W latach 2002, 2003 i 2005 przeprowadzono badania dotyczące wpływu ściółkowania gleby czarną folią polietylenową na plonowanie ogórka gruntowego odmiany Akord F1. Rośliny były uprawiane na glebie piaszczysto-gliniastej, z zastosowaniem nawadniania i fertygacji, prowadzonych przy użyciu linii kroplujących. Nie stwierdzono istotnych różnic w wielkości plonu ogólnego i handlowego owoców oraz zawartości suchej masy i cukrów w owocach z roślin uprawianych na glebie ściółkowanej i bez ściółki. Efektywność nawadniania na glebie ściółkowanej czarną folią była większa niż na glebie nieściółkowanej.

Opis:
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.

Opis:
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.

Opis:
In the Red River Delta (RRD) of Vietnam, small-pumping systems are one of main systems for paddy irrigation. It is imperative to analyze the operation and maintenance performance of irrigation systems by using the input factors when applying pricing mechanisms in the irrigation sector in Vietnam. In this study, based on the data of 48 irrigation systems managed by teams under irrigation companies, the non-parametric program, Data Envelopment Analysis, was used to measure the technical efficiency and scale efficiency for small-pumping scale irrigation systems in the Red River Delta. The seven input factors were the annual direct and indirect labor, materials, electricity, recurrent maintenance, overhead, and depreciation cost, and an output factor was the paddy areas irrigated by the systems. The results demonstrated that the average technical efficiency scores under constant returns to scale and variable returns to scale were 0.924 and 0.946, respectively. Thus, the wasted inputs were suggested to be 7.6% and 5.4% of the current input level, respectively. The average scale efficiency score was 0.977 and therefore, some 72.9% of the Decision-Making Units should adjust their input scales to achieve the efficiency in input factors.

Opis:
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:
In furrow irrigation, the maximum lateral movement of water in ridges is more desirable than the vertical downward movement. This can be achieved by compacting the furrows. Thus, the study examines the impact on furrow soil compaction by tractor wheel trafficking during mechanical operations in the different soil types. In this experiment, the three-wheel tractor compaction includes: 1) control (no soil compaction), 2) compaction through 3-wheel tractor passes, and 3) compaction through 6-wheel passes under three different soil textural classes such as: clay loam, silty clay loam and silty loam soils. The impact of various treatments on clay loam, silty clay loam, and silty loam under 3- and 6-wheel passes showed increased bulk density (7–12%), field capacity (9–19%), ridge storage efficiency (35–38%), water use efficiency (16–20.5%) and decreased soil porosity (7–16%), infiltration (8–20%), and furrow storage efficiency (28–41%) over the control. This study shows comparable results of 6-passes with other studies in which more than 6-passes were used to compact the soil. This study suggested that farmers can maximise water use efficiency by compacting their furrows using 6-passes tractor trafficking.

Surge flow irrigation is one of the irrigation techniques for controlling furrow irrigation. The aim of this study was to investigate the effect of surge furrow irrigation on water management compared with continuous irrigation for different tillage systems. An experimental field was treated with various tillage systems (mouldboard plough, chisel plough and rotary plough) and water irrigation application methods (continuous flow, control) in which irrigation water was applied continuously, and surge flow (3-surges, 4-surges and 5-surges) in which irrigation water was applied intermittently until it reached the tail end of the furrow. The results showed that water savings obtained using the surge technique were 18.58, 11.84 and 18.93% lower water use than with continuous flow, for the mouldboard, chisel and rotary ploughs, respectively. The 3-surges treatment with the rotary plough reduced the advance time by 25.36% from that for continuous irrigation. The 4-surges treatment with the mouldboard plough had the highest water application efficiency (88.13%). The 3-surges treatment with the rotary plough had the highest distribution uniformity (85.01%). The rotary plough did not cause as much soil aeration around the root system as the other tillage systems. The field research provided information about surge flow, aimed at reducing advance times and increasing irrigation efficiency.

Opis:
The article reviews one of the important problems of water usage – operational management of irrigation. The article discusses a methodological approach to the estimation of economic efficiency of water usage in the conditions of climate change in the territory concerned. So far, there has not been a simple method to determine this indicator. When assessing climatic conditions, taking into account their influence on the productivity of agricultural crops, it is necessary to take into account meteorological factors that have a decisive influence on the development of agricultural crops and, accordingly, determine their yield. These include primarily heat and moisture. Moreover, it is necessary to take into account their possible negative influence on the development of plants, considering that for each crop a certain optimum regime of temperature and soil moisture is required in different phases of its growth. To assess climatic conditions taking into account the potential crop productivity, we can use the CPA formula. Calculations have shown a close relationship between the CPA and the yield of agricultural crops. Correlation coefficients of the obtained bonds vary from 0.85 to 0.98 depending on the culture and the territory.

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 aim of the research was the evaluation of sprinkler irrigation and nitrogen fertilization on some selected features of the quality of malt and wort from ‘Marthe’ and ‘Mauritia’ malting barley grains. The field experiment was carried out in the years 2010-2012 at the Research Station of the University of Science and Technology in Mochełek near Bydgoszcz. As a result of 3-year field experiment and laboratory test of grain, malt and wort, it was found that introducing sprinkler irrigation into the production process of malting barley is a step justified by the obtained quality effects. It was found that in the case of irrigated malting barley cultivations nitrogen fertilization at the rate of 30 kg·ha-1 provides (in relation to control, non-irrigated treatment) the highest values of such parameters as weight of the technical barley crops, content of protein, extractivity of Pilsen type malt, amount of obtained wort and simplified mashing efficiency. The combination of sprinkler irrigation of malting barley plants with their nitrogen fertilization at the increased rates of 60 and 90 kg·ha-1, resulted in the following effect – high mass of the usable grain of crops remained but their quality deteriorated. Malt produced from malting barley fertilized with nitrogen at the rates of 60 and 90 kg·ha-1, in spite of applied sprinkler irrigation, was characterized by unacceptable – from the technological point of view - increased content of protein in malt in the amount of over 11.5% d.m., as well as huge decrease in malt extractivity (even by 2%) and lower, simplified mashing efficiency (below 70%).

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:
The work presents the research results of impact and effects of applying irrigation by sprinkling machine on the yield of medium-early potatoes. The research and observation conducted in growing seasons 2011, 2012 and 2013, on the private agricultural and production farm, in Kurów, located in the Ostrów Wielkopolski district, in the borough of Nowe Skalmierzyce, in the Wielkopolska Province. The area of the farm was 31 ha and 4 ha of potatoes were irrigated. The study confirmed that by using interventional irrigation in periods of water deficits, the medium-early potato yield increased by 30%, against the non-irrigated area. The evaluation of the research results also showed that patchy distribution of precipitation, in the analyzed growing season had an adverse influence on the crop. Frequent and long dry periods contributed to losses and decrease in potato yield.

Opis:
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.
