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.

Spring Rape

In the continental climate of the southern Urals, rapeseed compares favorably with many forage and traditional silage crops with a high protein content and adaptive properties. The cultivation of rapeseed guarantees the production of its own seeds, up to 40 percent of oil, 60 percent of cake and 98 percent of rapeseed flour. (The research purpose) The research purpose is in improving the efficiency of rapeseed cultivation and rational use of rapeseed seeds, rapeseed flour and oil in the agricultural production in the Chelyabinsk region. (Materials and methods) The influence of various forecrops on the productivity and quality of spring rape seeds in the links of grain-pair crop rotations in the Northern forest-steppe of the Chelyabinsk region were studied. Authors have analyzed the chemical composition of the soil and seeds of spring rape after various forecrops. (Results and discussion) The article proposes to reduce energy costs during pressing and reduce residual oil in the cake after pre-grinding of rapeseed by cutting method using a centrifugal-rotary shredder. The article shows that rapeseed flour has a good flowability and is easily mixed with other feeds. It was found that partial replacement of concentrates with rapeseed flour in the amount of 8-12 percent of the total weight in the diet of lactating cows contributes to an increase in milk productivity by 1.1-1.8 kilograms in terms of milk of 4 percent fat content. (Conclusions) It has been revealed that in order to increase the yield and quality of spring rape seeds, it is necessary to place them on the best forecrops. It was found that when 75 percent of rapeseed oil is mixed with 25 percent of diesel fuel, the obtained biodiesel is not inferior to diesel in terms of energy indicators. The article proves that when cultivating rapeseed for seeds on an area of 100 hectares, it is possible to produce 94.5 tons of biodiesel fuel, 106.0 tons of cake with an oil content of 5 percent and 8.4 tons of oil sludge, the estimated economic effect after sale is of 3,813,325 rubles.

The research purpose was to identify high-quality variety features of formation of yield capacity and quality of soybean seeds when applying seniccation and desiccation in the Left-bank forest-steppe of Ukraine. The research subject is Anna, Romance, Vasilkovskaya varieties of soybean, the elements of technology of cultivation (desiccation and seniccation), yield capacity and quality of seeds. The experiment was carried out according to the two-factor scheme in a 4-times repeat at the Institute of Agriculture of the Northeast of NAAS of Ukraine. The research results showed that the duration of vegetation was influenced both by varietal characteristics and the application of desiccation and seniccation. On average, the smallest period from the growing phase to the full ripeness was stated on the variant with Reglon Super 2.0 l/ga and Basta 2.0 l/ga desiccation (36-37 days). The maximum level of yield capacity on the average in 2007-2009 was obtained from Vasilkovskaya variety – 2.50 t/ga. Annushka variety provided significantly lower yields (2.0 t/ha), as it was proved by the calculated NSR05. In terms of yield capacity Romantika variety took an intermediate position of 2.38 t/ga. On the variants with the application of seniccation and desiccation a positive trend of their influence on the yield capacity of soybean seeds in all studied varieties was stated. So, on average, an increase of yield capacity was stated when applying: seniccation 5.0% solution of ammonium nitrate per 0.38 t/ga; 8.0% solution of urea per 0.45 t/ga; Reglon Super 2.0 l/ga per 0.24 t/ga; Basta 2.0 l/ga 0.3 t/ga as compared to the control. Application of seniccation favored the increase of protein content: urea solution by 0.7%; solution of ammonium nitrate by 0.5% compared to the control. On the variants of desiccation the protein content was at (33.9-34.1%). Oil content of the seed of studied varieties ranged from 20.0 to 24.1%.

Purpose. The aim of the research conducted during 2016-2019 was to determine the impact of technological methods on the indicators of corn grain quality to optimize the elements of growing technology depending on the directions of use in conditions of the Forest-Steppe natural zone of Ukraine. Methods – field, quantitative and weight, chemical, comparative and calculation, mathematical and statistical. Results. On the results of the research, dependences of formation of quality of grain on the content of protein, starch, fat in it and correlation dependencies between these indicators and yield of corn have been revealed. The best quality of grain of a forage and food direction is formed when applying high doses of mineral fertilizers, and for processing on bioethanol the optimal content of starch and protein is guaranteed at optimum and raised level of fertilizing. It was established that the content of protein, starch and fat had less effect on their yield from 1 hectare than the general yield level. The technologies of cultivation of different intensity as to their possible application for the production of grain of different directions of use with the given quality parameters, the yield of protein, starch, fat and bioethanol have been evaluated. Conclusions. The technology of corn growing with complex application of intensification elements in conditions of the Forest-Steppe zone, which includes introduction of N240P120K240 on the background of by-products of its predecessor, application of the soil and insurance herbicide, plant growth and micro-fertilizers is suitable for fodder and food purposes and ensured the yield of 12.1 t/ha of grain with protein content and yield – 10.56% and 1.28 t/ha, fat – 4.29% and 0.52 t/ha, starch – 71.27% and 8.62 t/ha. For processing on bioethanol effective is the technology of corn growing with the introduction of N180P120K180, by-products of the predecessor, soil herbicide and bio-stimulants, which provided a yield of 9.76 t/ha of grain with a starch content of 72.26% for the yield of 7.05 t/ha and yield of bioethanol at the level of 3982 l/ha.

In 2019-2020, the quality of lawn-type grass mixtures based on creeping clover (Trifolium repens L.), meadow fescue (Festuca pratensis), pasture ryegrass (Lolium perenne) and meadow bluegrass (Poa pratensis) was evaluated in the conditions of the forest-steppe of the Middle Volga region (Penza region). The studied factors are the composition of the mixtures (creeping clover + bluegrass component), the seeding rates of the components (40 + 70 %; 55 + 55 %; 70 + 40 %) and the background of mineral nutrition (without fertilizers, P45K45, N30P45K45). The growing season during the years of research was characterized by arid conditions, the hydrothermal coefficient (HTC) for the period May-September in 2019 was 0.79, in 2020 - 0.76. On average, over two years of grass mixtures of creeping clover with meadow bluegrass at a seeding rate of 40 + 70 % and 70 + 40 % (from the seeding rate in pure form), creeping clover with meadow fescue with a seeding rate of 70 + 40 % components at all doses of mineral fertilizers had the highest comprehensive assessment of the quality of the lawn. The grass mixtures of creeping clover with meadow bluegrass (70 + 40 %) and creeping clover with meadow fescue (70 + 40 %) against the background of application of N30P45K45 had the maximum indicators in terms of herbage density (1425 and 1475 pcs/m2), which significantly exceeded the control and the variant with the introduction of Р45К45. In these variants, the highest indicators of projective cover (97.5 %) and a comprehensive assessment of "excellent" and "highest quality". According to weediness, the crops were estimated at 1 point (slightly weedy), per 1 m2 of annual and biennial weeds there were 24-27 pcs., rhizome weeds - less than 10 pcs. per 1 m2, the area of weed projective cover did not exceed 5 %.

In the Siberian District, including the Tyumen region, a great contribution into production of foodgrain has been made by valuable and strong varieties of spring soft wheat Iren, Omskaya 36, Novosibirskaya 31. It should be noted that elements of cultivation technology of these varieties for seeds have been developed insufficiently. In the article, the 2016-2018 data have been analyzed according to the productivity and quality of seeds of the chosen wheat varieties in dependence to the level of mineral nutrition (for planned productivity of 4.5 and 6 t/ha). It has been established that in the conditions of the northern forest-steppe of the Tyumen region the level of mineral nutrition for productivity of 4-5 t/ha provided high quality of seeds. In the variant with NPK of 4 t/ha the yield of seeds of the general productivity was 73.0-77.8%, the mass of 1000 grains – 33.9-38.5, the protein content – 15.3-16.8%, the energy of germination – 58.0-67.3%, the laboratory viability – 94.3-96.5%. The main part of seeds (67-74%) sprouted in 5-6 seminal roots and when resowing in 2017-2018 it gave dense, strong shoots. Seeds from the chosen variant had advantage before the control without fertilizers and before variants with higher level of mineral nutrition in many quality indicators.  It has been established that germination energy of seeds closely correlated with protein content (r = 0.72…0.82) and insignificantly – with the mass of 1000 grains (r = 0.27…0.28). Between productivity and energy of germination of seeds the correlation was negative(r = -0,32…-0,40)

Spring Rape

One of the most dangerous pests of rape is a complex of the undulating flea beetles that can do harm to the plants from the phase of sprouting and until the harvest ripening. According to our research, all six species of the undulating flea beetles are spread in the Eastern Forest–Steppe of Ukraine. The most numerous species are Phyllotreta atra F. (about 71%) and Phyllotreta nigripes F., the latter is less numerous (about 16%). The rest 4 species make up from 0.4 to 8.8% in the population structure. The damage of spring rape sprouts caused by the leaf beetles both against the background with the fertilizers (N30P30K30) and against the background without the fertilizers significantly affects a weight of 1000 seeds. Against the background without the fertilizers it is a little less and R²=0.875 while against the background with the fertilizers R²=0.9986. The yield capacity of spring rape both against the background with the fertilizers (N30P30K30) and against the background without the fertilizers depends on the degree of the sprouts damaged by the leaf–eating pests largely. It is a little higher against the background without the fertilizers and R²=0.9995 while against the background with the fertilizers R²=0.9911. The presowing toxicity of spring rapeseeds with the subsequent spraying of the crops in the phase of sprouting, namely the toxicity of two pairs of true leaves, provides a reduction in the density of the undulating flea beetles population 7.5–10.0 times below the level of the economic threshold of harmfulness. The best field germination of rape seeds both against the background without the fertilizers and against the background with the fertilizers is noted. The applied insecticide and fungicide seed treatment agents have a negative affect on the laboratory germination of spring rape seed material. The worst indices of germination were noted in the variants when applying Royal FLO, 48% of water and suspension concentrate in the dose 5.0 L/t and Royal FLO, 48% of water and suspension concentrate+Taboo, 50% of suspension concentrate in the dose of 5.0+6.0 L/t and on the 9th day these indices were 77.0% and 76.5% respectively.

Objective of the research: to study the influence of the norms of mineral fertilizers on the yield and quality of seeds of oil flax varieties in the conditions of the northern forest-steppe of the Tyumen region. The studies were carried out on the experimental field of the State Agrarian University of the Northern Trans-Urals in 2019-2020. The soil of the experimental field is leached chernozem, thin, heavy loamy. Experimental options included: control, without fertilizers; NPK based on seed yield 2 t/ha; NPK based on seed yield of 3 t/ha. Increases in yield from the use of fertilizers in the studied varieties August and Sokol were obtained in 2019, the growing season of which was characterized by the amount of precipitation close to the long-term level. In 2020, when there was a shortage of precipitation, only the Sokol variety showed a positive reaction to fertilizers. Under the influence of fertilizers, the seed oil content of the August variety decreased, while the Sokol variety was at the same level in all variants.
