Opis:: The effect of foliar feeding with four biostimulants with active substances (Ecklonia maxima algae extract, titanium, humic substances, plant hormones: auxin and cytokinin) on the chlorophyll content and plant height of three Solanum tuberosum cultivars was investigated. A field experiment was carried out in 2015–2017 in eastern Poland in three growing seasons using the split-plot method. The cultivated varieties significantly differentiated the chlorophyll content (SPAD index) and plant height. The research showed the influence of varieties and many years of research on the height of potato plants. The biostimulants increased the value of the SPAD coefficient and the height of the potato plants.

Opis:: 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.

Opis:: This research examines the eutrophication process mainly by considering the chlorophyll-a concentration. A simple linear model was used to determine the correlation between Chlorophyll-a and dissolved inorganic phosphate (DIP). The research was carried out on river mouths in the north coast of Central Java. The results of the linear model show that the relationship between chlorophyll-a and DIP follows the logarithmic model with the log [Chloa] = 1.52 + 1.60 log [DIP], R² = 0.55. The model suggests that the high concentration of chlorophyll-a is related to dissolved inorganic phosphate concentrations. On the basis of the sufficient of conclusive evidence for these variables, the study sites with high stresses from several anthropogenic sources had higher chlorophyll-a than the sites that are relatively far from river mouths and lands.

Opis:: This study investigates the concentration of chlorophyll-a (chl-a) using the data of field observation and MODISAqua imagery. The field observation data were retrieved by using a conventional method and processed using spectrometric analysis. This study covers the coastal and near land areas which have different levels of anthropogenic activity. The results showed that the coastal waters of Semarang with a high level of anthropogenic activity persistently show a concentration of chlorophyll a (chl-a) twice as large as Jepara coastal waters. This comparison value is obtained based on imagery and field data. Meanwhile, the ratio of chl-a field data in each region shows a value of ±5 times greater than the MODIS data. Field observation data shows a higher value than the MODISAqua imagery data. The use of imagery data can be employed as a method of monitoring the eutrophication process on the coast. On the basis of the chlorophyll a classification and field observations, the coastal water of Semarang are classified as eutropic waters and Jepara is categorized as mesotropic category. The classification results will be different if monitoring is carried out using the image data with a location far from the mainland, the Semarang waters are included in the mesotropic category (> 2 mg•m-3) and Jepara is included in the oligotropic water category (< 2 mg•m-3).

Opis:: The paper presents the evaluation of trophic status of Lake Niepruszewskie in the years 1994–2013. This is the first lake in the Samica Stęszewska river, flowing dis-tally through the lakes of the Wielkopolski National Park. Source part of the Samica Stęszewska river basin was, in the years 2004–2012, included to the nitrate vulnerable zone (NVZ), and Niepruszewskie Lake was considered to be threatened by eutrophication. The evaluation of trophic status of the lake was made based on the concentration of nutrients (nitrogen and phosphorus) and indicators of eutrophication (chlorophyll a, water transparency Secchi disk marked) by referring them to the limit values for the eutrophication of surface waters as defined in the Regulation of the Minister of Environment of 23 December 2002 and other criteria used for the classification of the eutrophication of surface waters. Detailed and synthetic indexes of the trophic status (TSI) using the formula Carlson and the ratio of N:P were also made. Concentrations of the nutrients in Lake Niepruszewskie and eutrophication indexes reached high values, indicating a eutrophic or hypertrophic state of the lake. Detailed values of the trophic status index (TSI), on average over the period, corresponded to eutrophic, while in subsequent years they were varied – from mesotrophic to hypertrophic. The worst trophic status was recorded in 2003–2006, after the lowering of the lake dam-ming. The high value of N: P ratio indicates that the lake has huge surplus of nitrogen, and phosphorus is a productivity limiting factor.

Opis:: The chlorophyll-a (chl) abundances on the Fisheries Management Area of Indonesia Republic (WPP-RI 572), as fishery resources over the western coast of Sumatera (WSC) and Sunda Strait, were examined in this study. The extensive investigation on the mechanism ocean dynamics on chl variability along WSC was observed by using remotely sensed data on the surface. The spatial analysis was conducted using the Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua Ocean colour data for a period of January 2003 to December 2015. On seasonal time scale, the surface chlorophyll-a (schl) concentration in the southern tip of Sumatra is higher than the schl in the northern tip of Sumatra. The obtained results showed that the schl concentration in the southern tip of Sumatra increases (decreases) during the southeast (northwest) monsoons. Interestingly, its interactions with the southeast monsoon wind result in intensified coastal upwelling along the monsoon trough in July – August. It triggered a large bloom of the schl concentration from the upwelling region of southern tip Sumatra. Moreover, the schl in the center region followed the peak of the equatorial wind during the period transition in the Indian Ocean which is controlling the dynamics ocean such as upwelling event. Meanwhile, the opposite situation of the schl concentration observed low along the western coast of Sumatra during the northwest monsoon. At the same time, strong upwelling observed at the northern tip of Sumatra was associated with intense cooling on the sea surface temperature. It triggered a large bloom of high schl water from the upwelling region of northern Sumatra Island.

Opis:: The study presents scientific substantiation and determination of the dependence of leaf area formation and photosynthetic activity of sunflower plants under the influence of fertilizers and growth regulators. The field research was conducted in 2015-2017 in the fields of the Voznesensk district in the Mykolaiv region, Ukraine (GPS: 47.630518, 32.078974). The soil of the research field is common black soil with little humus accumulation and the content of hydrolyzed nitrogen – 1.5-1.8; the content of highly absorbable phosphorous – 4.5-7.0 and the content of exchangeable potassium – 12-15 mg/100 g of soil. The research was carried out by a two-factor scheme, where Factor A – the rate of mineral nutrition (the test plot without fertilizers; N30P45; N60P90); and Factor В – foliar feeding with the Wuxal Microplant, Khelafit Combi and Fitomare preparations. The weather conditions in the years of the research were typical for this growing zone. It was established that the year 2017 was the least favorable with excessively low soil moisture and high temperature regime for growing the crop, and the weather conditions of 2015 and 2016 were the most favorable for cultivating sunflower. The research made it possible to determine that fertilizers combined with multifunctional preparations had a considerable impact on the leaf area and photosynthetic potential of agrocenosis. It proves that foliar feeding of sunflower plants at the stage of 6-8 true leaves with growth regulators contributed not only to a change in the total chlorophyll content, but also to its fractional composition. In all the cases there was a major increase in the content of the fraction "а". In particular, the maximal increase in this fraction was 90%, whereas the difference did not exceed 76% in the fraction "b". Under nonfertilized conditions these indices were 48 and 13%, respectively.

A three-year experiment was conducted to examine the following factors: factor I – three potato cultivars: Bartek, Gawin, Honorata; factor II – five methods of an application of herbicides and biostimulants: 1. control unit without chemical control, 2. the Harrier 295 ZC herbicide (linuron + clomazone), 3. the Harrier 295 ZC herbicide (linuron + clomazone) and the Kelpak SL biostimulant (Ecklonia maxima), 4. the Sencor 70 WG herbicide (metribuzin), 5. the Sencor 70 WG herbicide (metribuzin) and the Asahi SL biostimulant (sodium para-nitrophenol, sodium ortho-nitrophenol, sodium 5-nitroguaiacol). The cultivars investigated in the experiment significantly affected the leaf greenness index SPAD, plant height, yield of large tubers and the vitamin C content. The herbicides and biostimulants enhanced the values of the examined potato characteristics. Linear correlation coefficients confirm a strong, significant, positive correlation between the SPAD index and plant height, yield of large tubers and vitamin C content.

Opis:: The Kendal Regency area is one of the areas on the northern coast of Central Java that has been experiencing rapid industrial development. The high human activity in this area will impact the quality of water in these surrounding areas and affect the fertility of the waters. The concentrations of chlorophyll-a (Chl-a) and total suspended matter (TSM) are major water quality parameters that can be retrieved using remotely sensed data. The retrieval satellite of the 3 OLCI chosen in this study has a 300 m spatial resolution. This study aimed to see the distribution and effect of total suspended matter (TSM) on chlorophyll-a based on measurement and retrieval of Sentinel 3 imagery using the linear regression method. The results show the chlorophyll-a distribution and the value from retrieval satellite are higher and occur over larger surface area compared to chlorophyll-a measurements. The linear regression model of chlorophyll-a by retrieval satellite imagery and measurement is y = 0.65x + 4.65 with R2 = 0.54. The presence of high amounts of suspended solids in the waters causes disturbances in the reflectance values, which are recorded by the retrieval of satellite. The model regression chlorophyll-a with TSM accuracy from retrieval satellite results in the equation y = -0.0416x + 5.14 (R2 = 0.45, p = 0.05, n = 13). The determination (R2) coefficient value is 0.445, which means that suspended solids have a 44.5% effect on chlorophyll-a and 55.5% is influenced by other factors and not examined in this study. The results show that TSM has an influence on the accuracy of chlorophyll-a and retrieval satellite recording can be disrupted if waters have high turbidity.

Opis:: Obecnie dostępne metody oceny stopnia eutrofizacji są kosztowne, czasochłonne i wymagają posiadania zaawansowanej aparatury laboratoryjnej oraz wiedzy. Celem niniejszej pracy było określenie prostej i uzasadnionej ekonomicznie metody monitorowania skutków eutrofizacji wody na obszarze rolniczym oraz powiązanie wyników monitorowania parametrów fizykochemicznych wody z fluorescencją chlorofilu jako potencjalnego zagrożenia dla zdrowia na podstawie ustalonych poziomów alarmowych. Badania prowadzono w zbiornikach wodnych zlokalizowanych na obszarze wiejskim, różniących się intensywnością eksploatowania terenów przyległych: znajdujących się w otoczeniu obszarów intensywnie uprawianych rolniczo oraz w obszarze chronionym rezerwatu przyrody. W pracy określono wydajność aparatu fotosyntetycznego glonów oraz właściwości fizykochemiczne wody. Badania wykazały, że wzrost intensywności fluorescencji chlorofilu związany jest ze zwiększonym ładunkiem substancji biogennych oraz ze wzmożonym wzrostem mikroogranizmow zawierających chlorofil. Wyniki wskazują, na możliwość zastosowana pomiarów fluorescencji chlorofilu do oceny stopnia eutrofizacji wód. Zaprezentowana metoda ma szanse na nieinwazyjną, szybką i precyzyjną ocenę stanu fizjologicznego ekosystemów wodnych na obszarach wiejskich, szczególnie narażonych na procesy eutrofizacji.
The currently available methods for the assessment of the eutrophication degree are expensive, time-consuming and require advanced laboratory equipment and knowledge. The aim of this work was to determine a simple and economically justified method of monitoring the effects of eutrophication of water in the agricultural area and linking the results of monitoring physicochemical parameters of water with chlorophyll fluorescence as a potential health risk on the basis of established alarm levels. The research was conducted in water reservoirs located in the rural area, differing in the intensity of exploitation of adjacent areas: located in the vicinity of intensively cultivated areas and in the protected area of the nature reserve. The work determined the efficiency of the photosynthetic apparatus of algae and physicochemical properties of water. The studies have shown that the increase in the chlorophyll fluorescence intensity is associated with an raised biogenic load and an increased occurrence of chlorophyll-containing micro-fractions. The results indicate the possibility of using chlorophyll fluorescence measurements to assess the degree of water eutrophication. The presented method can be used for a non-invasive, quick and precise assessment of the physiological status of water ecosystems in rural areas, particularly vulnerable to the eutrophication processes.

Opis:: In order to understand the effects of ultraviolet-B (UV-B) radiation and salinity stress on the visual quality and morphological parameters, one-year-old seedlings of rosemary (Rosmarinus officinalis L.) were grown under three UV-B levels (0, 4.32, 6.05 kJ m-2 d-1) and four salinity regimes (Control, 50, 100 and 150 mM NaCl) under greenhouse conditions. The results showed that enhanced UV-B radiation increased visual quality, growth index, plant biomass, shoot/root ratio, number of branches and leaves, leaf fresh and dry weight, leaf area index, specific leaf area, leaf thickness. The UV-B radiation had no significant effect on root length; however, shoot height, length of axillary shoots, length of inter node, leaf area, leaf length and width and concentration of chlorophyll b were negatively impacted by the UV-B radiation. On the other hand, salinity caused a significant decrease in plant biomass, root length, shoot height, shoot/root ratio, length of axillary shoots, length of inter node, number of branches and leaf area, leaf area index, leaf length and width, leaf fresh and dry weight, specific leaf area and concentration of Photosynthetic pigments. However, the number leaves and leaf thickness significantly increased under NaCl salinity treatments. Visual quality and growth index were hardly affected by increasing salinity until 100 mM, but declined clearly at 150 mM NaCl salinity. The interaction between UV-B irradiation and salinity showed that pre-treatment with UV-B irradiation alleviated the harmful effects of NaCl and improved the visual quality rosemary plants.

Opis:: Adding humic acid to soil can improve soil structure and fertility, which can lead to better plant growth and higher crop yields. Extracting humic acid from compost is a sustainable and environmentally friendly way to obtain a valuable organic material. Humic acid (HA) can be extracted from compost relatively easily and at a low cost, making it an attractive option for farmers. In this study, we investigated the use of sugarcane bagasse (SB) and immature horse manure (IHM) as bulking agents for the composting of separated municipal solid waste (SMSW) and the extraction and characterization of humic acid from the mature composts produced. Fertilizing solutions containing different concentrations of humic acid were prepared and used to evaluate their effects on turnip crop growth and various biochemical parameters during cultivation. The results showed that the humic acid extracted from the composts had high yields and were rich in elemental carbon. The application of humic acid at both low and high concentrations resulted in a significant improvement in all the parameters measured except for the total protein in the roots, which did not differ significantly between the humic acid concentrations. The yield, root diameter and fresh weight increased significantly, and the leaf area was proportional to the humic acid concentration of the solution used. The highest increase in chlorophyll a content was observed in the treatment of humic acid extracted from composts C2 and C3 at a concentration of 0.1 gL-1, with an increase of 31% and 37%, respectively, compared to the control. The use of humic acid provided by co-compost can be considered a successful management strategy for degraded sandy soils and sustainable agriculture production in sandy poor soils worldwide.

Opis:: The research on the effect of sulfur oxides (SO₂), nitrogen oxides (N_xO_y) and phosphorus oxides (P₂O₅) on carbon dioxide (CO₂) uptake dynamics of chlorophyll synthesizing microalgae was conducted. The analytic dependences of microalgae growth rates under their CO₂ uptake, SO₂, N_xO_y and P₂O₅ concentrations were obtained. Mathematical models enabling to predict the maximum values of SO₂, N_xO_y and P₂O₅ oxides concentrations without inhibiting the CO₂ uptake dynamics of chlorophyll synthesizing microalgae were built based on the obtained experimental research results.
