The purpose of the study is to identify the effectiveness of various types of fertilizers and biologics Bisolbifit on the yield and quality indicators of spring barley grain. Experiments were conducted in 2015-2017 in Ulyanovsk region. The soil of the experimental site is represented by leached Chernozem, heavy loam. The scheme of experience included two factors. Factor A-control; pre-sowing seed treatment with Bisolbifit; NPK in pure form at a dose of 15 kg of active substance per hectare; modified NPK (NPKm) at a dose of 15 kg of active substance per hectare; modified NPK (1/2 NPKm) at a dose of 7.5 kg of active substance per hectare. Factor B (background): zero-without fertilizers; pure ammonium nitrate (NH4NO3) at a dose of 40 kg of active substance per hectare; modified ammonium nitrate (1/2 NH4NO3m) at a dose of 20 kg of active substance per hectare. Inoculation of seeds with a biological preparation was performed by semi-dry etching 1...2 days before sowing at a dose of 400...600 g per hectare of seeds. For the preparation of modified NPK and ammonium nitrate, the biological preparation Bisolbifit was used in a dose of 4 kg per 1 ton of fertilizers. The drug was applied to mineral fertilizer granules on the day of sowing. All types of fertilizers and biologics studied led to an increase in yield. The use of mineral fertilizers in pure form (untreated with biologics) increased the yield by 0.26...0.41 t/ha, modified – by 0.38...0.54 t/ha, biologics – by 0.06...0.19 t/ha, compared with the control (2.67 t/ha). The use of fertilizers and biologics increased the weight of 1000 grains – the best options were with modified NPK at a dose of 15 kg d. V./ha-49.4...53.0 g. the quality indicators of the studied agricultural practices did not have a significant impact. The highest payback of fertilizers by increasing the yield was recorded in the variant with pre-sowing treatment of seeds with Bisolbifit biologics and amounted to 7.7...11.4 kg/kg

Grain Protein

Providing the brewing industry with locally produced raw materials is important both from an economic point of view and in terms of import substitution. Breeders create brewing barley varieties with a reduced protein content, however, in production they often use universal varieties that combine high yields with an average protein content of 11–12%. For such varieties, it is necessary to develop technological methods for obtaining a crop with specified properties, depending on the purposes of using the products. The quality indicators of barley grain and the efficiency of its production are significantly influenced by mineral fertilizers and the minimization of soil cultivation. In this regard, the authors studied the effect of minimal tillage on the yield and grain quality of spring barley of the Vladimir variety at two levels of mineral nutrition (without fertilizers 26 and with full supply oif mineral fertilizer – N35P40K135) in a two-factor field experiment carried out in 2018–2019 on the medium-loamy light gray forest soil. The experiment helped determine the yield and structure of the crop, the content of protein, starch, and grain hoodness (hull content). It was found that the lack of precipitation during the barley tillering – heading period leads to a decrease in grain yield by 40.0–54.8% as compared with the conditions of increased moisturizing. At the same time, there was an increase in the grain protein content by 1.4–1.7% and the grain filminess by 0.5–0.9%. The use of moderate rates of complete mineral fertilizer (N35P40K85) led to an increase in the barley yield by an average of 13.2% and the grain protein content by an average of 0.2%. On the other hand, it led to a decrease in the grain filminess by 0.2% and starch content by 0.4–0.6%. The positive effect of nitrogen fertilizers on the increase in protein content in barley grain was higher under minimal tillage. Under minimal tillage, regardless of the level of moisture supply and mineral nutrition, there was a tendency towards a decrease in the barley yield by an average of 3.9%, mainly due to a decrease in the density of the productive stalk. There was also a tendency towards a decrease in the protein content in the barley grain – by 0.3% – when no complete mineral fertilizer was used.

The research purpose is to study the effect of systematic application of various doses of mineral fertilizers on productivity, grain quality, value of spring barley productivity elements, determine an optimal doses of nitrogen, phosphorus and potassium in the arid conditions of the Middle Volga region. Improving nutrition with the use of fertilizers contributed to an increase in productivity values. The average yield was 0.18–0.76 t/ha. The use of maximum doses of nitrogen, phosphorus and potassium did not increase productivity in arid conditions. Nitrogen plays a leading role in increasing barley productivity. The agronomic effectiveness of fertilizers depended on the doses of active substances. An increase was 2.1–5.8 kg of barley grain per 1 kg of active substances. The most stable increase was observed when applying N60Р0-60К0-30. Rational doses are as follows: nitrogen 60–90 kg a.e./ha when applying P60K30, phosphorus 30–60 kg a.e./ha when applying N60K30, potassium 30 kg a.e./ha when applying N60Р60. The best option is N60Р0-60К0-30.

Studies to determine the effect of mineral, biomineral fertilizers and biological products on the content of nutrients (nitrogen, phosphorus and potassium) during the growing season in spring barley plants were carried out in 2015-2017 on leached heavy loam chernozem of Ulyanovsk region. The soil of the experimental site contained: humus 6.43...6.62 % (according to Tyurin), total nitrogen-0.26 % (according to Kjeldahl), mobile phosphorus and potassium-214 ... 228 and 101...117 mg/kg of soil, respectively (according to Chirikov), pHKCl – 6.3...6.8 (GOST 26483-85), hydrolytic acidity – 1.20...1.29 mmol/100 g of soil (according to Kappen). The scheme of the experiment included the following options: without fertilizers (control); Bisolbiphite (seed inoculation); N15P15K15 (regular azofoska); N15P15K15m (azofoska modified with BisolbiPhite); N7,5P7,5K7,5m (azofoska modified with BisolbiPhite in a half dose). We used a complex mineral fertilizer-azofoska in a dose of 15 kg d. v. per 1 ha of nitrogen, phosphorus and potassium and a microbiological preparation BisolbiFit, which serves as a modifier of seeds and mineral fertilizers. The drug is based on a strain of bacteria of the rhizosphere Bacillus subtilis H-13, isolated from chernozem soil. Inoculation of spring barley seeds with a biological preparation was carried out 1...2 days before sowing (400...600 g/t of seeds), mineral fertilizer was treated on the day of its application to the soil (4 kg/t of fertilizers). As the studied crop, the variety of spring barley Nutans 553, zoned in Ulyanovsk region, was sown on experimental plots. Mineral fertilizers and biological preparation had a positive effect on the nutrient content of spring barley plants. Under the influence of the studied fertilizer, the nitrogen content in the green mass of barley increased by 0.09...0.30%, phosphorus − by 0.09...0.18%, potassium-by 0.25...1.10 %, in relation to the variant where mineral fertilizer and microbiological preparation were not used. As a result of the correlation analysis, a positive relationship was established between the yield of barley and the content of nutrients in plants during the tillering, tubing and flowering phases: with nitrogen (r = 0.78; 0.83; 0.75), phosphorus (r = 0.80; 0.42; 0.71) and potassium (r = 0.66; 0.59; 0.91). As a result of this research work, it was found that the use of the studied fertilizers and the biological product BisolbiFit positively affected the content of the main nutrients (nitrogen, phosphorus and potassium) in spring barley plants in all phases of its development.

Little attention has been paid to the effect of long-term fertilizer application on concentrations of elements in grain of barley produced on the metal non-contaminated agricultural soil. In 2010, we analyzed yield and concentrations of elements in grain of spring barley in unfertilized control, mineral fertilizer application (N<sub>4</sub>P<sub>2</sub>K<sub>2</sub> &ndash; 70, 60 and<br />100 kg N, P and K per ha) and combinations of farmyard manure or poultry litter with mineral fertilizer (FMN<sub>4</sub>P<sub>2</sub>K<sub>2</sub> and PLN<sub>4</sub>P<sub>2</sub>K<sub>2</sub>) treatments in the Ruzyně Fertilizer Experiment established on Luvisol in 1955 in Prague (Czech Republic). The yield of grain ranged from 4.03 to 9.74 t/ha in the control and FMN<sub>4</sub>P<sub>2</sub>K<sub>2</sub> treatment. There was a positive effect of fertilizer application on concentrations of nitrogen, phosphorusand potassium, but no effect on concentrations of calcium and magnesium. With the exception of iron, concentrations of micro (copper and zinc) and risk elements (arsenic, cadmium, chromium, lead, manganese and nickel) were not significantly affected by the fertilizer treatments. Long-term use of organic and mineral fertilizers with appropriate application rates does not represent any risk for contamination of barley grain by risk elements on mineral rich and metal non-contaminated agricultural soils.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The research was conducted in 2017-2018 in the Nizhny Novgorod region on light-gray forest soil in the link of “spring wheat-pea” crop rotation. The article presents the results of study of the influence of soil tillage systems (traditional moldboard tillage with moldboard plow; non-moldboard “deep” tillage with boardless plow; non-moldboard “shallow” tillage with chisel cultivator Pottinger Synkro 5030 K; minimum tillage with disc harrow XM 44660 NOTHAD; zero tillage (No-till) with grain drill Sunflower 9421-20, mineral fertilizers (N60P60K60 kg of active ingredient) and straw destructors (ammonium nitrate in the dose of N10 kg of active ingredient per 1 t of straw and biological preparation  Stimix®Niva 2 ltr/ha) on the change in the indicator of biological activity of the soil and the yield of pea variety Krasivy. In the conditions of insufficient precipitation of the growing season of 2018, No-till technology resulted in a decrease in the average biological activity of the soil  by the tillage systems under study in pea plantings of Krasivy variety: by 6.3 % (from 18.6 to 12.3 %) compared to the traditional moldboard tillage system with moldboard plow; by 4.7 % (from 17.0 to 12.3 %) compared to the non-moldboard “deep” tillage with boardless plow; by 3.5 % (from 15.8 to 12.3 %) compared to the non-moldboard "shallow" tillage with a chisel cultivator; by 4.9 % (from 17.2 to 12.3 %) compared to the minimum processing with disk harrow. The use of the biological preparation Stimix®Niva as a straw destructor in arid conditions of 2018 was more effective than the use of ammonium nitrate in field test variants without application of mineral fertilizers (N60P60K60). The biological activity of the soil increased on fall plowing with moldboard plow by 3.8 % (20.8 and 17.0% respectively); on fall plowing with boardless plow by 5.3 % (18. 8 and 13.5 %); on minimum tillage with a disc harrow by 4.8 % (18.9 and 14.1 %). Under the weather conditions of 2018, the highest yield of Krasivy pea variety was obtained in the variant of field experiment where fall plowing with soil overturning to the depth of 20-22 cm with the use of ammonium nitrate as a straw destructor in a dose of 10 kg of active ingredient per 1 ton of straw was used as basic cultivation. The use of mineral fertilizers (N60P60K60) by this system of soil tillage in dry conditions did not affect the yield of Krasivy pea variety (2.70-of 2.76 t/ha). When using the No-till technology of pea production, the obtained yield in the conditions of the Nizhny Novgorod region in 2018 ranged from 0.74 to 2.24 t/ha.

The aim of the research was to study the effect of the inclusion of different types of perennial leguminous plants as winter wheat precursors in the crop rotation on the rate of accumulation of heavy metals in the soil compared to traditional winter wheat predecessors. The objectives of the research are to develop measures to reduce the accumulation of heavy metals in agricultural soils under conditions of modern crop rotation, limited by the number of crops grown and winter wheat. The accumulations of heavy metals in soils were calculated during the cultivation of the main crops of crop rotation with intensive fertilizer. The concentration of heavy metals in the soil was determined before and after the cultivation of legume precursors. Field studies were carried out during 2013-2017. On gray podzolized medium loamy soils of the Agronomichesky Research Institute of Vinnytsia National Agrarian University. We calculated the volumes of heavy metals with optimal rates of mineral fertilizer application for the most common types of crops grown in crop rotation. Four types of perennial grasses were sown: sowing alfalfa, meadow clover, horned lamb, sainfoin and eastern goatskin. After their four years of use, winter wheat was sown. The control was the predecessors in the following sequence: winter wheat - sunflower - winter wheat - corn. Laboratory studies of the content of mobile forms of heavy metals in soil were carried out in the Vinnytsia branch of the State Center for the Protection of Soil Fertility. Analysis of soil contamination with heavy metals during fertilization of major cereals showed that the amount of mineral fertilizers is from 257 kg/ha to 571 kg/ha for ammonium nitrate, from 175 to 225 kg/ha for double superphosphate and from 58 to 75 kg/ha on potassium chloride. According to the volume of mineral fertilizers used in the cultivation of winter wheat, 1944 mg / ha of lead and 339 mg / ha of cadmium enter the soil. Of these, with ammonium nitrate - 51.4% and 7.4%, respectively, with double superphosphate - 39.6% and 41.3% and with potassium chloride - 9.0% and 51.3%. When growing corn per 1 ha with mineral fertilizers, 2357 mg of lead and 434 mg of cadmium are applied, of which with ammonium nitrate - 48.4% and 6.7%, respectively, with double superphosphate - 42% and 41% and with potassium chloride. - 9.6% and 51.8%. Cultivation of spring barley leads to the receipt of mineral fertilizers to soils 1458 mg/ha of lead and 327 mg/ha of cadmium, of which with ammonium nitrate - respectively 35.2% and 4.0%, with double superphosphate - 52.8% and 42.8% and with potassium chloride - 12.0% and 53.2%. Mineral fertilization of winter rape leads to the entry into the soil per 1 ha of 2223 mg of lead and 390 mg of cadmium, of which with ammonium nitrate - respectively 51.4% and 7.4%, with double superphosphate - 39.6% and 41% and with potassium chloride - 9.0% and 51.5%. With mineral fertilizers for growing sunflower in the soil per 1 ha gets 2073 mg of lead and 427 mg of cadmium, of which with ammonium nitrate - respectively 41.4% and 5.2%, double superphosphate - 47.8% and 42.2 % and potassium chloride - 10.8% and 52.6%. The positive effect of growing leguminous perennial herbs on the decrease in the concentration of heavy metals in the soil and grain of winter wheat has been established. Under the conditions of intensive farming by Vinnitskaya, lead and cadmium fall into the soil for the use of mineral fertilizers in accordance with 1944 mg/ha and 339 mg/ha for growing winter wheat, 2357 mg/ha and 434 mg/ha for growing corn, 1458 mg/ha and 327 mg/ha when growing spring barley, 2223 mg/ha and 390 mg/ha when growing sunflower. The four-year cultivation of perennial leguminous grasses under intensive farming reduced the concentration of lead in the soil from 1.33 to 3.2 times and cadmium from 37 to 54 times compared with cereal crops, which contributed to improving the quality of winter wheat grain by reducing the concentration of lead from 1 7 to 2.4 times and cadmium from 1.4 times to 2.1 times.

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 %.

The article presents the results of field research conducted in 2018-2019 on leached Chernozem of the Volga forest-steppe. The objects of research are varieties of spring wheat-Tulaykovskaya 10, Yoldyz and Tulaykovskaya 108. At different seeding rates of 5.0 and 5.5 million germinating seeds per ha, the effect of mineral fertilizers on 1 ha was studied. They were represented by a complete mineral fertilizer (azofoska) and fertilizing with a mineral nitrogen fertilizer in the tillering phase at doses of 30, 60 and 90 kg of AD/ha against this background. Analysis of the yield of spring wheat varieties indicates that the harvest of grain variety Yoldyz in variants with a seeding rate of 5.5 million germinating seeds per ha against the background of the application of ammonium nitrate at a dose of 60 kg of DA (2.52 t/ha) was superior to other varieties Tulaykovskaya 10 and Tulaykovskaya 108 (2.51 and 2.46 t/ha). The maximum increase in seed productivity when adding ammonium nitrate in the tillage phase of the crop was in Tulaykovskaya 10 variety (0.34 t/ha), the lowest in the Yoldyz variety (0.06 t/ha) compared to the variant with amofoska application in the pre-sowing cultivation. When increasing the doses of nitrogen fertilizers there was an increase in the water content of all the studied varieties by 1-3 PCs. While increasing the seeding rate from 5.0 to 5.5 million germinating seeds per 1 ha the number of grains in the ear changed on average for varieties by 1-2 PCs. Of all the studied varieties, the largest mass of 1,000 grains was in the Yoldyz variety (40.56 g) after azofoska application in the presowing cultivation + N60 during tillering at a seeding rate of 5.0 million germinating seeds per 1 ha, the smallest in the Tulaykovskaya 108 variety (37.87 g) after azofoska application at a dose of 0.15 t/ha at a seeding rate of 5.0 million   germinating seeds per 1 ha.
