The results of a study of the effectiveness of the joint application of potato mineral and organic fertilizers are presented. The studies were carried out in 2017–2018. on the drained lands of the Tver region. Objects of research - potatoes of the Scarb variety, mineral and organic fertilizers in various doses. Organic fertilizers are products of the processing of organic raw materials based on fermentation processes - multipurpose compost (KMN) and BiGuEM. Mineral fertilizers - ammonium nitrate, double superphosphate and potassium chloride. In the work we used experimental methods - field experiments and theoretical research methods - mathematical statistics. Evaluation of the optimal fertilizer doses showed that BiHuEM organic fertilizer at a dose of 3 t / ha, when used together with mineral fertilizers at a dose equivalent to 3 t BiGuEM, provided potato resistance to late blight compared to the version where KMN was used - almost 8% in 2017 and 12% - in 2018, and compared with the option without the use of fertilizers (control) - by 61% and 23%, respectively. This combination of fertilizers provided the maximum yield (both general and marketable) in comparison with the control by 45% when calculating both types of yield in 2017, and in 2018 by 38% of the total and 53% of the commodity yield. A greater increase in potato yield was also revealed in the variant with BiGueM in comparison with the variant of using KMN - by 4.5% and 5.7% in 2017 and in 2018 by 6.1% and 10%, respectively. An increase in the quality of potatoes was noted, which is confirmed by the low content of nitrates in them, as well as by the increased content of starch, which was especially noted in 2017 - 34.3 g / kg and 15.99%, respectively.

Barley is a crop, requires the availability of available nutrients in the soil, especially at the be-ginning of the growing season. The aim of the research was to determine the effectiveness of the aftereffect of using vermicompost when growing spring barley on different backgrounds in the Donetsk region. The studies were carried out according to the methodology of the field experiment of B. A. Dospehova. Research methods: field, supplemented by analytical studies, measurements, calculations and observations. The studies were conducted in 2017–2019 by laboratory-field method in field crop rotation in the experimental sections of the Donetsk SSES NAAS. The repetition in the experiments is 3-fold. The location of the plots is systematic. The soil is alkaline-chernozemic carbonate, having an average supply of mineral nitrogen and mobile phosphorus, low – potassium. The humus content of 4,2 % indicates a high potential soil fertility, but to realize the potential of the culture, additional application of phosphorus-potassium fertilizers is necessary. The technology for growing crops is generally accepted for the farms of the region, with the ex- ception of the factors studied. Variety of barley spring Avers. The experience scheme provides for: control (without fertilizers); background – saturation of crop rotation with vermicompost granular 2 t/ha; background + N30P30K30; background + N60P60K60; N30P30K30. The use of organic fertilizers under the predecessor in crop rotation provided improve nutriti-on conditions for plants, which positively affected the growth and development of spring barley plants. So, on the variants with the use of mineral fertilizers, the highest indices of the number of productive stems and the structure of the crop were noted in the background. The variant where N60P60K60 was added in the background produced the largest mass of 1000 grains – 49,8 g, which is 4,6 % higher than the control. Analysis of the study indicates the positive effect of the aftereffect of organic fertilizer (ver-micompost) on the yield of spring barley. The maximum yield of spring barley was obtained against the background of aftereffect of vermicompost 2 t/ha and the application of mineral fertilizers N60P60K60 – 5,05 t/ha, but due to high production costs, the profitability level is 114,9 %. The application of organic fertilizers under the background provides a yield of 3,67 t/ha and the highest level of profitability of 140,6 %. The optimal technological option provides for the introduction of mineral fertilizers in the norm N30P30K30 amid predecessor saturation with vermicompost. This allows increasing the yield up to 4,90 t/ha (by 1,46 t/ha or 42,4 % to the control) and obtaining a profitability level of 136,1 %. The use only of mineral fertilizer N30P30K30 in severely arid weather conditions of the steppe zone allows increasing the yield by 0,70 t/ha compared to the control but, due to the high cost of pro-duction, leads to a low production profitability of 99,6 %. Key words: spring barley, background, vermicompost, mineral fertilizers, yield, economic effici-ency.

The role of macro– and micronutrients for corn plants is great. They increase the intensity of photosynthesis, participate in biological processes. The work is devoted to the development of science–based methods for increasing the yield and quality of corn. Field experiments were conducted in the northwestern zone of Azerbaijan. Test sites were laid in 4-fold repetition, in 6 versions. Used: ammonium nitrate, simple superphosphate, potassium sulfate, manure, compost of various waste products. All agricultural activities were carried out according to the developed technology. Before ploughing, the entire rate of manure, phosphorus and potassium was introduced, in early spring before tillage. As a result, it was revealed that with the introduction of 20 t/ha of compost — the yield of corn was 85.1 c/ha, i.e. an increase of 15.9 c/ha. It can be concluded that mineral fertilizers in combination with manure in the proportions chosen by the authors effectively affect not only the growth and development of plants, corn productivity also increases.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

In the development of vegetable farming by the community, there are fundamental problems which are generally carried out conventionally with the use of synthetic fertilizers and pesticides to determine the success of their farming. With the farming system, the community suffers a lot of losses because the inputs used are relatively expensive and on the other hand the products become cheap because the quality is not guaranteed. The solution to this problem is to develop bio-culture organic fertilizers and bio-urine whose raw materials are available in the region. The partner village development program aims to conduct training on the making and development of liquid organic fertilizer bio-culture and biourine to support the cultivation of organic vegetables. The method of approach applied is technology transfer (TT) and entrepreneurship capacity building (ECB) which is carried out with the Participatory Rural Approach (PRA) approach ) which in its implementation uses the method of lecture/discussion, training, making demo plotting, and assistance. The results achieved in the implementation of this program were that participants were able to make and develop liquid organic bioculture fertilizers and biourin and apply it to their farms as an alternative to chemical fertilizers

Annotation Purpose. Summarize the regulatory and technological requirements for the production of organic (organo-mineral) fertilizers on the base of sewage sludge. Methods. Analysis and generalization of the requirements of regulatory documents on the management of organic waste and their use as raw materials for the production of organic fertilizers and soil improvers. Results. The current legislative, departmental and regulatory documentary base in Ukraine concerning the treatment of sediment resulting from biological sewage treatment at municipal wastewater treatment plants for its further use in agriculture as fertilizers is analysed. Indicators are identified and analysed to determine the possibility, feasibility, efficiency and scope of organic fertilizers produced using sewage sludge. The analysis of changes in the content of organic matter and total nitrogen in the sewage sludge during its storage at the sewage treatment plant sites is presented. The technological feasibility of using sludge of different shelf life in composting production has been determined. Conclusions 1. The regulatory framework of Ukraine contains a sufficiently complete list of indicators that should be met by organic raw materials (sewage sludge) for further use as organic fertilizers. Some of these indicators – bio security and heavy metals content – can be improved in the composting process of fertilizers. 2. Fresh sediment, as well as sediment accumulated in the last late autumn and winter periods, is of main value for use as a raw material in the production of organic fertilizers. 3. The use in the production of compost sludge stored on sludge sites for a period of half a year or more requires special control of the process of decontamination. In this case, it is advisable to use additional means of wastewater decontamination. Keywords: heavy metals, manure, humus, decontamination, composting, organic fertilizers, sewage sludge.

Развитие органического земледелия, в первую очередь, зависит от наличия органических удобрений и биопрепаратов. Цель исследований – на основе утилизации органических отходов и сырья разработать полифункциональные биопрепараты из компонентов животного и растительного происхождения и изучить их влияние на показатели агрофитоценозов и урожайность полевых и садовых культур. В работе использованы результаты исследований по разработке полифункциональных биопрепаратов, а также их эффективности на опытном поле Самарского ГАУ в 2017-2019 гг. В результате была разработана ассортиментная линейка биопрепаратов «АгроТоник» с функциями удобрения и биостимулятора роста: «Цветовод», «Садовод», «Овощевод», «Полевод», «Лесовод» и «Универсальный». «АгроТоник», в отличие от многих органических и минеральных удобрений, содержит все необходимые для растений компоненты: макро-, мезо- и микроэлементы в легкодоступной форме, микроорганизмы, стимуляторы роста – биоактивные фитогормоны, аминокислоты растительного происхождения, витамины, комплекс целлюлозолитических ферментов, почвенные антибиотики, гуминовые вещества, биоприлипатель. Многокомпонентный биопрепарат с функциями удобрения, фунгицида и бактерицида снижал пораженность растений озимой пшеницы на 16,7-27,1 %, по отношению к контролю, и на 17,4-22,6 %, по сравнению с минеральными удобрениями. Биопрепарат повышал урожайность озимой пшеницы на 7,7-25,4 % по сравнению с контролем, тогда как применение пестицида только на 5,3-11,5 %, при стоимости однократно внесенного гербицида в среднем 500,00 руб./га, а биопрепарата – 300,00 руб./га при двукратной обработке. The development of organic farming primarily depends on the availability of organic fertilizers and biological products. The goal of the research is to develop multifunctional biological products from components of animal and plant origin based on the utilization of organic waste and raw materials and to study their impact on the indicators of agrophytocenoses and the yield of field and horticultural crops. The work uses the results of research on the development of multifunctional biological products, as well as their effectiveness in the experimental field of the Samara State Agrarian University in 2017-2019. As a result, the line of "AgroTonik" biological products with the functions of fertilizer and the growth biostimulator was developed: «Tsvetovod», «Sadovod», «Ovoshchevod», «Polevod», «Lesovod» and «Universal'niy». "AgroTonik", unlike many organic and mineral fertilizers, contains all the components necessary for plants: macro -, meso- and microelements in an easily available form, microorganisms, growth stimulators – bioactive phytohormones, amino acids of plant origin, vitamins, a complex of cellulosolytic enzymes, soil antibiotics, humic substances, bio-sticking agent. The multicomponent biological product with the functions of fertilizer, fungicide and bactericide reduced the affection of winter wheat plants by 16.7-27.1 % concerning the control, and by 17.4-22.6 %, in comparison with mineral fertilizers. The biological product increased the yield of winter wheat by 7.7-25.4% compared to the control, while the use of a pesticide only by 5.3-11.5 %, with the cost of a single herbicide on average 500 rubles/ha, and a biological product – 300 rubles/ha with double treatment.

Inland valley wetlands with higher soil moisture than surrounding uplands offer a yet unexplored opportunity for increasing maize production in East Africa. For three consecutive years, we conducted field experiments to assess the potential of an inland valley in Central Uganda for producing dry season maize. A randomized complete block design was used with six treatments including farmer’s practice, unfertilized control, organic and inorganic fertilizer applications at high and low rates. These were repeated four times at each of the three hydrological positions of the inland valley (fringe, middle, and center). The maize grain yield of 3.4 t ha–1 (mean across treatments and years) exceeded the national yield average by 42%. High and sustained soil moisture in the center position of the inland valley was associated with the highest grain yields irrespective of the year. Due to soil moisture deficit in the fringe and middle hydrological positions, grain yields were not only lower but also highly variable. Intensive manuring with a combination of green and poultry manure produced high yields that were comparable to those with mineral fertilizers (both at 120 kg N ha–1). Lower amounts of either mineral or organic fertilizer (60 kg N ha–1) provided no yield gain over the unfertilized control. Inland valley wetlands, thus, offer promise for farmers to harvest an additional maize crop during the dry season, thus contributing to farm income and regional food security.

The experiment assessed the influence of various biofertilizers and biostimulants on the growth characteristics of the root system, its colonization by arbuscular mycorrhizal fungi and the yielding of sweet cherry trees in field conditions. The experiment, conducted in Pomological Orchard of Research Institute of Horticulture located in Skierniewice during 2011–2014, involved the use of a mycorrhizal substrate, organic fertilizers and biostimulant in randomised block design. The control combination consisted of plants fertilized with mineral fertilizers (NPK). The use of the organic fertilizer BF Ekomix in dose 100 g per tree each year in the spring significantly increased the number of root tips in comparison with the control trees. There was also a tendency for the roots to lengthen and increase their surface area under the influence of this biofertilizer. In addition, the inoculation of roots with the mycorrhizal substrate in dose 200 g per tree per year stimulated the colonization of the roots of sweet cherry trees by arbuscular mycorrhizal fungi, which in turn led to improved root growth parameters.
