The paper presents results of studying the effectiveness of a complex of organic fertilizers (straw, green manure, biological product) in the technology of winter wheat cultivation. Experimental field studies were carried out on the experimental field of Ulyanovsk State Agrarian University in 2018 - 2020 in a five-field grain-green manure crop rotation: green manure fallow - winter wheat - millet - spring wheat - barley. The experiment scheme included 6 variants: 1. Control, 2. Forecrop straw (barley) + green manure (vetch-oat mixture), 3. Straw + 10 kg N / t straw + green manure, 4. Straw + biological product + green manure, 5. Biological product + green manure, 6.N64P32K54 (NPK). The experiment was carried out in a 4-fold repetition with a randomized placement of plots, the record area of which was 72 m2 (4x18), total - 120 m2 (6x20). Mineral fertilizers are calculated for the planned yield of winter wheat of 4.5 t / ha. “Biocomposite-correct” product produced by AO Shchelkovo Agrokhim was used as a biological fertilizer. The experiment focused on the change of soil agrochemical parameters (typical medium-thick medium-loamy black soil) depending on application of fertilizers, grain yield, its quality and environmental safety; economic assessment of winter wheat cultivation technology with application of fertilizers was conducted. A significant improvement of the soil nutrient regime was found in case of application of a complex of organic methods, which was slightly inferior to the variant with full fertilization. The yield increase of winter wheat grain in case of combined usage of straw, green manure and a biological product was 0.67 t / ha (control - 5.83 t / ha). The usage of a complex 80 of biological techniques for winter wheat cultivation is environmentally safe and cost effective.

Целью исследований являлось совершенствование элементов технологии возделывания озимой пшеницы в лесостепи Среднего Поволжья, позволяющих оптимизировать условия роста и развития. Исследованиями установлено, что вид пара не оказывал существенного влияния на плотность почвы. После сидерального пара запасы продуктивной влаги метрового слоя перед посевом снижались, в среднем, на 6,4 мм. Размещение озимой пшеницы после сидерального пара приводило к несущественному уменьшению площади листьев на 0,14 тыс. м2/га, по сравнению с черным паром. Наибольший вклад в формирование продуктивности озимой пшеницы оказало удобрение Гумостим, которое способствовало увеличению площади листовой поверхности на 5,1 тыс. м2/га, урожайности на 0,46 т/га по отношению к контролю. The aim of the research was to improve the elements of winter wheat cultivation technology in the forest-steppe zone of the Middle Volga region, which allow to optimize the conditions for growth and development. The studies found that the type of fallow did not significantly affect the density of the soil. After green-manured fallow, the reserves of productive moisture in the meter layer decreased before sowing, on average, by 6.4 mm. Winter wheat placing after green manure fallow led to an insignificant decrease in leaf area by 0.14 thousand m2/ha, compared to black fallow. The greatest contribution to the formation of the productivity of winter wheat was made by the fertilizer Gumostim, which contributed to an increase in the leaf area by 5.1 thousand m2/ha, in yield - by 0.46 t/ha in relation to the control.

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.

The article considers the results of observation of the growth, development and formation of winter wheat grain yield depending on the methods of basic soil treatment, applied fertilizers and biofungicide  Phytotrix. It was found out that the options with shallow and surface treatment were not inferior to the control in terms of yield (plowing by 20-22cm). Mineral fertilizers in a dose of N30P30K30 provided an increase in the productivity of winter wheat relative to the non-fertilized background by an average of 0.54 t / ha. Treatment of plants with phytotrix increased grain production on a non-fertilized background by 0.33 t / ha, on the background of N30P30K30 by 0.76 t / ha. The maximum yield of winter wheat-5.03 t / ha was achieved with the use of combing on the background of N30P30K30 + Phytotrix. The greatest responsiveness in collecting grain from fertilizers was observed in the variants of comb-back processing and surface disking, where the increase was 0.68-0.89 t / ha against the background of N30P30K30 application, and 1.05 t/ha against the background of N30P30K30 + Phytotrix relative to the natural background of the corresponding treatments.Apply mineral fertilizers in a dose of N30P30K30, with the application of biofungicide treatment on the vegetation of the crop, which will increase the yield by 0.76 t / ha, compared to the non-fertilized background.

The study deals with organic, mineral and organo-mineral systems of winter wheat fertilization in the conditions of the Volga forest-steppe. According to the organic fertilization system, straw of the predecessor, green manure and Biocomposite-correct were introduced into the soil (typical medium-thick medium loamy chernozem) for green manure mass (vetch-oat mixture). The organo-mineral system included two options: straw applied together with nitrogen in a dose of 10 kg per 1 ton of straw and zeolite enriched with amino acids. The mineral fertilizers were nitrogene phosphorus with the NPK content of 16 kg ai/ha, carbamide and potassium chloride. In addition, highly siliceous rock zeolite was applied as a fertilizer. It was found that the use of organic and organomineral fertilizers improves the nutrient regime of the soil; in terms of the content of nitrogen, phosphorus and potassium in the arable layer, these options were not inferior to the option with the use of mineral fertilizers. When introducing zeolite enriched with amino acids, the yield of winter wheat exceeded the option with the use of mineral fertilizers by 0.59 t/ha. The use of organic and organo-mineral fertilizers contributes to the production of environmentally friendly products

The experimental studies were carried out on the fields of the Sumy NAU Training Research and Production Complex (TRPC) during 2016–2018.The soil of the experimental plot is typical deep-medium humus, large-dusty and medium-loam black soil on forest trees. The subject of the research was a white mustard variety of Oslava created at the Institute of Feed and Agriculture of the Podillya NAASU, entered in the Register of varieties suitable for cultivation in Ukraine in 2010. The aim of the research is to optimize the nutrition of the white mustard variety of Oslava through the complex application of mineral fertilizers and foliar fertilization under the conditions of the northeastern forest-steppe of Ukraine. The analysis of weather conditions, in particular the hydrothermal coefficient of Selyaninov (HTC), established that 2016 season was wet (HTC = 1.60), 2017 and 2018 were dry (HTC = 0.59 and 0.46). During the research, the cultivation technology was generally accepted in the experimental area, except for the elements studied. The results of the three-year study on the influence of foliar fertilizing under different mineral nutrition backgrounds on the yield of the white mustard variety Oslava are presented. It was found that the application of mineral fertilizers and complex fertilizers for the foliar feeding had a positive effect on the morphometric parameters of the white mustard, in particular, increased the plant height and the number of branches of the first order. The use of mineral fertilizers at the rate of N30P30K30 provided an increase in the yield by 0.34 t/ha, N60P60K60 – by 0.55 t/ha, N90P90K90 – by 0.61 t/ha on an average compared to the control. Therefore, for the maximum yield (2.14–2.21 t/ha) with a mass of 1000 seeds (5.39–5.54 g) of the white mustard under the conditions of the Northeastern Forest-Steppe of Ukraine, foliar fertilizing of Vuxal boron (3.0 l/ha) + Vuxal bioaminoplant 3.0 l/ha) and Spectrum B + Mo (2.0 l/ha) + Spectrum Ascorist (3.0 l/ha) should be applied on the background of N60-90P60-90K60-90, what provided an increase in the yield compared to the control of 0.58-0.65 t/ha.

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%.

The Borisovsky district of the Belgorod region, located in the south-west of the forest-steppe zone of the Central Forest Region, was chosen for the study. The study covered an 11-year period, during which 3 cycles of agrochemical soil survey were conducted in the district - in 2010, 2016 and 2020. Analyzing the use of mineral and organic fertilizers, an increase in crop yield indicators was noted. Thus, an increase in the dose of organic fertilizers (up to 1.96 t/ha) and mineral fertilizers (up to 127.2 kg/ha) made it possible to obtain 5.13 t/ha of winter wheat, 4.19 t/ha of spring barley, 7.9 t/ha of corn for grain and 3.29 t/ha of sunflower seeds. In addition, the content of macro and microelements in the soil has changed. The active fight against soil acidity affected the content of available forms of phosphorus and zinc, the indicators of which decreased slightly.
