Topicality. Nowadays, the main purpose of agro-industrial complex and renewable energy is to increase the productivity of corn for grain and silage. For biogas production the proper selection of maize hybrids and energy assessment of their cultivation technology is needed. Issues. Optimization of technological methods and increasing the yield per area unit is one of the ways to improve the energy efficiency of crop production, including for the purposes of bioenergy. Energy analysis assists to compare energy consumption for growing crop and energy content in the obtained yield. Aim. To determine the influence of macro- and microfertilizers on the energy efficiency of growing maize hybrids for biogas production. Materials and Methods. The research was conducted in 2019–2021 in the “Poultry Farm Korobivsky" Andrushivka district of Zhytomyr region. In a three-factor experiment, it was studied maize hybrids: Amaroc, Bogatyr, KWS 381, Karifols; macrofertilizers, kg/ha: without fertilizers, N90Р60К60, N120Р90К90; microfertilizers: without application, YaraVita Teprosyn NP + Zn seed treatment (5 l/t) and spraying maize in the 3–5 leaves stage with YaraVita Maize Boost (4 l/ha), seed treatment (0.15 kg/t) with YaraTera Tenso Cocktail and spraying maize in the 3–5 leaves with Yara Vita Kombiphos (3 l/ha). Results. It was found that the biogas output for the mid-early maize hybrids Amaroc and Bogatyr was 9062.0–13716.3 m3/ha, and for the mid-ripening KWS 381 and Karifols was higher by 9.8–36.5 % (11635.3–15589.5 m3/ha). Biogas output was higher by 15.2–30.9 % and 1.8–3.6 % due to using macrofertilizers and microfertilizers compared to the variants without their application. There was no significant difference in biogas output between the second and third variants with microfertilizers. It was identified that energy efficiency ratio (Ke) increased for studied maize hybrids when N90Р60К60 and N120Р90К90 were applied. Conclusions. The highest biogas and energy output was 15589,5 m3/ha and 333,6 GJ/ha was obtained for the mid-ripening hybrid Karifols when pre-sowing seed treatment with YaraTera Tenso Cocktail (0.15 kg/t) and spraying maize in the 3–5 leaves stage with YaraVita Kombiphos (3 l/ha) were carried out on the background of N120Р90К90. In our opinion, for biogas production, the cultivation of Amaros, Bogatyr, KVS 381 and Carifols hybrids is more efficient when used pre-sowing seed treatment with Yara Tera Tenso Cocktail (0.15 kg/t) and spraying maize with YaraVita Kombiphos (3 l/ha) in the 3–5 leaves stage without macrofertilizer application that provides the highest energy factor in the range of 7.7–9.3. Key words: biogas output, pre-sowing seed treatment, energy output, energy consumption, energy efficiency ratio.

Abstract The study results on using macro- and micronutrients in the cultivation of white lupine (Lupinusalbus L.) in the soil and climatic conditions of the Central Black Earth region of Russia are presented. Field trials were carried out in 2018-2020 at the Department of Plant Growing, Breeding and Vegetable Growing in Belgorod State Agrarian University. The object of research is a high-intensity variety of white lupine Degas. The subject of research is the Aquamix microfertilizer of two brands – Aquamix-T (for seed treatment) and Aquamix-TV (for foliar dressing), macrofertilizers – potassium sulphate (K2SO4) and potassium monophosphate (KH2PO4). The weather conditions during the years of the experiments were unfavorable for the growth and development of lupine, since during the entire growing season of the plants an increased temperature regime was observed with a deficit of precipitation. The soil cover of the experimental field is represented by typical chernozem with an average content of basic nutrients. The accounting area of the plot is 18 m2, the replication is fourfold, the placement is systematic. The experiment included seven options: 1) control (without fertilizers), 2) seed treatment with Aquamix-T micronutrient fertilizer, 3) seed treatment with Aquamix-T micronutrient fertilizer and foliar fertilization with Aquamix-TV micronutrient fertilizer, 4) seed treatment with Aquamix-Tilist micronutrient fertilizer solution potassium sulphate, 5) seed treatment with microfertilizer Aquamix-Tilist feeding with potassium monophosphate solution, 6) seed treatment with micronutrient Aquamix-Tilist fertilizer with a mixture of Aquamix-TV + potassium sulphate, 7) seed treatment with micronutrient fertilizer Aquamix-Tilist fertilization with potassium monophosphate mixture. Analysis of the data obtained showed that the highest yield of white lupine seeds was obtained on the variants with seed treatment with Aquamix-T micronutrient fertilizer together with foliar dressing with Aquamix-TV micronutrient fertilizer in combination with K2SO4 or KH2PO4 macrofertilizers, which was 3.64 and 3.62 t/ha, respectively, which is 0.64 and 0.62 t/ha or 21.3 and 20.5% above the control variant.

Substantiation and development of technology elements for obtaining a sustainable productivity of lupine grain is an important and urgent task for expanding the area under this grain crop. There have been considered the study results of the effect of fertilizers ‘Aquamix ST’, ‘Metaborat Kaliya’, ‘Tiaton’ on productivity and grain quality of white lupine. The study was carried out at the All-Russian Research Institute of Lupine – a branch of the FWRC FPA, in the soil and climatic conditions of the southwestern part of the Non-Chernozem zone in 2018-2019. The purpose of the current study was to estimate the efficiency of these innovative micro- and macrofertilizers and the methods of their application on a number of indicators that improve productivity and grain quality of white lupine. The application of fertilizers ‘Aquamix ST’ and ‘Metaborat Kaliya’ contributed to an increase of white lupine grain productivity on 37.5 and 35.4%. There has been determined protein increase from 5.0 to 5.8% in grain of the white lupine variety ‘Piligrim’ in all application variants of ‘Aquamix ST’. The use of ‘Aquamix ST’ and ‘Metaborat Kaliya’ in the vegetation period of plants reduced alkaloid content of lupine grain on 24.7-34.6%. Application of ‘Aquamix ST’ and ‘Metaborat Kaliya’ in white lupine budding stage increased carotene content in grain on 34.3 and 25.0%, respectively. The analysis of the data showed that the variant including pre-seeding treatment with ‘Aquamix ST’ and subsequent treatment in the budding stage of plants was characterized by the maximum amount of lysine and carotene. There was noted that the application of micro- and macrofertilizers resulted in an increase in feed units and digestible protein. Application of ‘Aquamix ST’, including pre-seeding treatment and two treatments in the vegetation period of plants provided the largest yield of digestible protein (1.26 t/ha), 6.0 t/h of feed units, and 54.8 GJ/ha of exchangeable energy. ‘Metaborat Kaliya’, used in the treatment of plants in their budding phase, showed almost the same results. The options that combined high productivity with high grain quality were more valuable according their feed value.

Исследования проводились в 2019–2021 годах на опытном поле Тверской ГСХА. Целью данной научной работы было установить роль макроэлементов минеральных удобрений и микроудобрений в хелатной форме («Аквамикс СТ», «Акварин 5») в формировании урожая клевера и определить их влияние на качество получаемых кормов и плодородие дерново-подзолистых почв в короткоротационном трёхпольном кормовом севообороте в условиях Нечернозёмной зоны. Задачи исследования: изучить роль фона питания в формировании урожая клевера; определить влияние внесённых макро- и микроудобрений на качество полученных кормов. Структура посевных площадей: зерновые — 33%, занятый пар (вико-овёс) — 33%, травы (клевер луговой) — 33%. Сорта культур в севообороте: овёс посевной Кречет, клевер луговой Трио, вика яровая Льговская 22. Фактор A — минеральные макроудобрения (без внесения удобрений (контроль); внесение 1/2 рассчитанной нормы (N25P25K25); внесение полной нормы (N50P50K50). Фактор B — внекорневая подкормка физиологически активными веществами (без внесения микроэлементов; обработка посевов препаратом «Аквамикс СТ»; обработка посевов препаратом «Акварин 5»).Установлено, что внесение физиологически активных веществ в чистом виде позволило получить статистически значимую прибавку урожайности зелёной массы клевера лугового при благоприятных агроклиматических условиях на бедных микроэлементами почвах. Самая высокая урожайность за один укос (+19 т/га зелёной массы) была отмечена на делянках с клевером, обработанным препаратом «Акварин 5» в чистом виде. Применение препарата «Аквамикс СТ» повышало урожайность клевера на 22,2–48,8%, а по фону минеральных удобрений в полной дозе (N50P50K50) — на 4,8–24,3%. Лучшие по качеству корма получены при обработке клевера лугового препаратом «Акварин 5» (8,36 т/га сырой клетчатки и 4,6 т/га сырого протеина), использование его в сочетании с комплексными минеральными удобрениями увеличивало урожайность, но снижало качество получаемой продукции. This research was conducted at the Tver State Agricultural Academy in 2019–2021. Its aim was to test the effect of macronutrients of mineral fertilizers and the chelated forms of microfertilizers (“Akvamiks ST”, “Akvarin 5”) on clover productivity, feed quality and the fertility of sod-podzolic soil in a short three-field crop rotation in the Non-Chernozem region. The objectives were: to determine the correlation between the nutritional background and clover yield; to analyze the impact of macro- and microfertilizers on feed quality. Gramineous occupied 33% of the cultivated area, the mixture of vetch and oats — 33%, other grasses (red clover) — 33%. Crop varieties used in the rotation: “Krechet” (oat), “Trio” (red clover), “Lgovskaya 22” (spring vetch). Factor A — mineral macrofertilizers (no fertilizers, control); the application of 1/2 of N25P25K25; the fertilization with N50P50K50. Factor B — topdressing with physiologically active substances (without micronutrient application; the treatments with the “Akvamiks ST” or “Akvarin 5” preparations). The application of physiologically active substances significantly increased the production of green mass of red clover on the micronutrient-poor soil under favorable conditions. Clover treated with “Akvarin 5” provided the highest yield for one cut (+19 t ha-1 of green mass). “Akvamiks ST” improved clover productivity by 22.2–48.8%, on the background of N50P50K50 — by 4.8–24.3%. Red clover treated by “Akvarin 5” provided the feed of the best quality (8.36 t ha-1 of crude fiber and 4.6 t ha-1 of crude protein). The application of “Akvarin 5” in combination with complex mineral fertilizers increased crop productivity but reduced the quality of the product obtained.

The purpose of the study was to scientifically substantiate the effectiveness of polishans and Macroshans as elements of the technology of winter wheat cultivation in the conditions of the Central forest-steppe, their effect on productivity and product quality. Experiments, observations, records, and analyses were carried out using the field experience methodology [6]. Statistical processing of the results was performed using methods of analysis of variance. Treatment of seeds with Polishans at a dose of 0.2 l / t promoted the growth and development of winter wheat plants on all backgrounds of fertilizer application - N45P45K45 and N90P90K90, and without applying the main fertilizer. Seed treatment with Palisander and processing plants Microsensor plant height of winter wheat increased on the background without fertilizers by 3.2 cm (4,5%), against making N90P90K90 - 2.7 cm (3.5%), and in the background making N45P45K45 - 4.2 cm (5.5 %). When treating seeds with Polishance, the coefficient of productive bushiness of plants was 1.94 on the background without fertilizers and tended to increase on the studied backgrounds of fertilizer 1.97-2.01. The yield of winter wheat in the studies was affected by the lack of available moisture for the formation of reproductive organs. At the same time, the effect of both macrofertilizers and microfertilizers, depending on the time of their application, on the yield of winter wheat was very clearly traced. The highest productivity of winter wheat was obtained with the following complex of studied agricultural methods: seed treatment with Polishans (0.2 l / t) + treatment of crops with Macrochance (0.25 l / ha) twice during the growing season-tillering and earing and all this against the background of the main fertilizer N90P90K90. The use of the Macrochance polymicrobial increased the gluten content by 2-4% while increasing the IDC index to 65-74 units, which corresponded to the I quality group.

Bocconia is an evergreen plant belonging to the poppy family, and has been used in folk medicine since ancient times. The unique feature of plume poppy to cure various diseases can be explained by the alkaloids, sanguinarin and heleritrin, available in its green component. In the period of 2019 – 2021 in the Belgorod branch of the federal state budgetary scientific institution «All-Russian Institute of medicinal and aromatic plants» field studies were carried out to study the effect of AgroMaster complex fertilizer of grade 13-40-13 with microelements on the productivity of plume poppy. Complex fertilizers are an important reserve for increasing the productivity of crops, including medicinal and aromatic plants [4, p. 273]. Along with the main application of mineral fertilizers, a significant role belongs to plant fertilization, especially complex fertilizers with trace elements. The main components of complex fertilizers are macrofertilizers (nitrogen, phosphorus, potassium, and others), which are necessary for proper growth and development of any crops. Auxiliary composition of complex fertilizers includes such important chemical elements as zinc, copper, manganese, and others. All of the above makes the use of complex fertilizers an indispensable method of increasing the productivity of cultivated crops [6, p. 194; 7, p. 138; 11, p. 55]. The objectives of the study are to study the peculiarities of adaptation, growth processes and yields of bocconia in specific agro-ecological conditions. Variants of field study included different doses of AgroMaster 13-40-13 fertilizer (from 2 to 5 kg/ha) with single and double treatment of plants to identify the optimal value. The greatest intensity of growth processes, as well as the growth of leafy mass has been found in the double treatment of plants at a dose of 2.0 + 2.0 kg/ha. Variant with maximum dose of fertilizer is 5,0 kg/ha at double treatment provided insignificant yield increase – 0,1 t/ ha against the background of the best variant.

In recent years, significant advances in nanotechnology have increased the ability to produce nanoparticles of physiologically important metals on a large scale, which are now used to improve fertilizer formulations to increase uptake by plant cells and minimize nutrient losses. Fertilizers with nanostructure can increase the efficiency of nutrient use through mechanisms such as targeted delivery, slow or controlled release. The aim of the research is to substantiate a compensatory scheme for the use of biodynamic nanofertilizers (nanocomplex micronutrient fertilizers with organic acids) by partially replacing the main macrofertilizers in the spring wheat fertilization system. The research was conducted on the basis of the educational and scientific laboratory Department of Plant Industry of the National University of Life and Environmental Sciences of Ukraine. In research, there were used the methods of field experiments of A.O. Rozhkov, notching method and scanning method for determination of leaf surface area. The studies showed that it is possible to replace within 30-40% of the recommended amount of mineral fertilizers with biodynamic nanofertilizers in the spring wheat fertilization system. In general, the use of nanofertilizers increased wheat growth and improved yield and yield components. Substitution of mineral fertilizers, Innoparmis Agroscience Biodynamic fertilizers, provides a more favourable 86-88% survival rate of spring wheat plants during the growing season. By replacing 34% of the recommended rate of mineral fertilizers, the content of photosynthetic pigments in wheat leaves increases by 5% and the leaf surface area increases by 7%. The created compensatory schemes for the use of biodynamic nanofertilizers by partial (34% in the wheat fertilization system) replacement of the main macronutrients can increase the yield of spring wheat by 9.9%. The proven possibility of replacing mineral fertilizers with biodynamic nanofertilizers in the fertilization system of agricultural crops will reduce environmental pollution and the economic dependency of using mineral fertilizers against the background of their rapid increase in price in recent years

The main directions of research on chemical means of protecting fodder crops from diseases, pests and weeds in the field fodder production of the All-Russian Fodder Research Institute are given. Studies on toxicological assessment of feed and soil are given. Plant Protection Department included three laboratories: the Herbicide Laboratory, the Plant Protection Laboratory and the Feed Toxicological Evaluation Laboratory. The Laboratory of Herbicides was established in 1967 to conduct research on the chemical method of controlling weeds on fodder crops, hayfields and pastures. Research on the study of pests of fodder crops was started in 1939 in the newly created laboratory for the protection of fodder crops from pests and diseases. The Feed Toxicology Assessment Laboratory was established in 1980 to assess pesticide residues in crop and soil. As a result of the studies, a system of measures for clover from pests has been developed; alfalfa diseases and pests and measures to combat them in the Non-Chernozem zone were studied. Pests and pathogens of corn, root crops, peas, lupine and other fodder crops were identified; their biology, ecology and harmfulness have been studied. A set of protective measures has been developed to combat the main pests and diseases of fodder crops, including soil cultivation techniques, early sowing dates, the use of resistant varieties, micro- and macrofertilizers, pre-sowing treatment of seeds with combined preparations, etc. Plant Protection Department carried out work with herbicides. As a result of research begun in 1950, a method was developed to clean the meadows from weedy herbaceous vegetation with the help of preparations 2,4-D and 2M-4X. A chemical method for the destruction of woody and shrubby vegetation with the help of the same preparations in the Non-Chernozem zone of the European part of the USSR has been developed. Methods of using herbicides on crops of almost all fodder crops have been developed: perennial and annual legumes and cereal grasses for green mass and seeds, corn, fodder beets, rapeseed, etc. The theoretical issues of the mutual influence of fodder crops and weeds are studied, the substantiation of the effectiveness of the use of herbicides on different types of soils is given.

Abstract Agriculture continues to move forward confidently. Before our eyes, the agrarian industry is reviving, becoming stronger, taking a strong position at the forefront of the Russian economy. The most important achievement of 2017 was a record grain harvest of 130 million tons. This result was achieved not only by increasing the cultivated areas, which increased by 620 thousand hectares in 2017, but also thanks to the record yield, which amounted to 28 kg / ha, which is 80% higher than in 2000. The maximum harvest in the history of new and Soviet Russia, which will ensure our country a strong leadership in the world wheat market. Russian agriculture remains a driver of the country’s economic development. For the second year in a row, we get a record harvest of not only grain, but also sugar beets and sunflowers, the production of soybeans, rapeseed and greenhouse vegetables is growing. In the new season, grain exports will reach 45 million tons, including more than 35 million tons of wheat. Russia is expanding the geography of its presence, having mastered new directions for the supply of agricultural products. At the end of 10 months of 2017, grain exports increased by 22% compared to the same period in 2016 and amounted to 32 million tons. During the same time, the export of Russian wheat exceeded 24 million tons, which is 23% more than a year earlier. … In Russia, over 17 years, the volume of grain production increased 2 times, sugar beet and sunflower - 2-3 times, soybeans and rapeseed - 10, greenhouse vegetables - 1.8, poultry meat - 6, pork - 2. Fish - 2 times. Greenhouse vegetable growing and horticulture are developing intensively. Progress is being made in the development of animal husbandry and aquaculture. The dairy industry is undergoing a significant transformation, and production volumes on farms are growing. These are new growth points for the agro-industrial complex. Thanks to the achievements of domestic scientists, grain production of agricultural crops can be increased due to many factors. One of the factors is foliar dressing with liquid micro- and macro-fertilizers. Therefore, we studied various combinations of liquid micro-, macrofertilizers, as well as the bio-logical product Albit, in order to identify the best option and recommend it for produc-tion.

Based on the results of the research, the orientation of the processes of forming the optimal nutrient regime on drained organic soils under corn for grain was determined by establishing scientifcally based doses of mineral fertilizers, depending on the methods that take into account the characteristics of these soils and methodological approaches to determine the doses of mineral fertilizers in the conditions of feld stationary experiment on drained organic soils of the floodplain of the Supii River. It was established that the application of mineral fertilizers leads to the strengthening of mineralization processes, which rises with increasing doses of fertilizers, which, in turn, leads to the accumulation of nutrients that affect the yield of cultivated crops and their migration into drainage waters. The increase in the content of nitrogen (N-NO3, N-НН4) and phosphorus (P2O5) compounds in drained organic soil are caused by both organic matter mineralization and mixing of vivianite and freshwater shells layers with peat soil, which causes an intensive oxidation process in the combined with CaСО 3 compounds, and as a result, organic matter decomposes into a partially humic complex of organic and mineral substances. Available for corn consumption nutrients further accumulate in the soil. The highest yield of corn per grain (8.34 t/ha) was obtained with the application of fertilizer doses based on the data of long-term studies (P45K120 with the addition of 2.0 l/ha of the combined preparation with the growth stimulator "Organic Balance"). The introduction of such doses of mineral fertilizers provides the greatest increase in yield per unit of applied fertilizers, and their leaching into drainage waters did not exceed the maximum permissible concentrations of water management objects for economic and cultural and domestic use. The use of justifed doses of fertilizers in corn crops ensures the highest yield with cost-effective costs per unit of production. It also takes into account the environmental aspects of mineral fertilizers, which prevent excessive leaching of biogenic substances into drainage waters, and, as a result, reduces the pollution of river waters. Key words: macrofertilizers, growth stimulator, calculation methods, fertilizers, organic soils, corn, ecology, productivity.

Relevance. At present, the issues of mineral nutrition of medicinal plants with essential elements remain unstudied, and the lack of certain microelements in soils is an underestimated agroecological factor. This necessitates the study of the effect of different doses of zinc and copper fertilizers on the content of mobile forms of zinc and copper in the meadow-chernozem soil when cultivating Achillea millefolium L. and Tanacetum vulgare L. in the southern forest-steppe conditions of Western Siberia.Methods. The research objects were meadow-chernozem soil, Achillea millefolium L., Tanacetum vulgare L. The field experiment was conducted during 2012–2015 on the experimental field of the Omsk State Agrarian University. Microfertilizers in the experiments were applied once in the year of planting medicinal plants. Zinc fertilizers (CH3COOH)2Zn) were applied in doses of 20, 40, 60, 80 kg/ha, copper (CH3COOH)2Cu) in doses of 2.4, 4.9, 7.2, 9.7 kg/ha against macrofertilizer (N135P45K45). Soil samples were collected and analyzed annually in the growing phase.Results. The research revealed that zinc and copper fertilizers on optimal macroelement background at low zinc (< 2,0 mg/kg) and copper content in soil (< 1,5 mg/kg) provided increase of zinc and copper mobile forms content in soil by 108,3% and 54,5% (Achillea millefolium L.) and 672,7% and 61,5% (Tanacetum vulgare L.), respectively, when applied in soil in acetate form. Optimal levels of the content of mobile forms of zinc and copper in the soil were 2.5 mg/kg and 0.17 mg/kg for Achillea millefolium L. respectively, 8.5 mg/kg and 0.21 mg/kg for Tanacetum vulgare L.
