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.

The Impact

The article presents findings of the influence of different levels of mineral nutrition on plant growth and development, the impact of fertilizers on the botanical composition, on the productivity and forage benefits of cereal-bean agrocenoses in the forest-steppe zone of the Baikal region. The objects of research were mixed crops of oats with peas and millet with vetch, peas, and Austrian winter pea. Legumes are the main source of protein increase in feed. In the field, the most widespread, among legumes, were vetch, sowing peas, field peas (Austrian winter pea). As a result of phenological observations, it was found that the growth and development of plants depended on the biological characteristics of crops, weather conditions and directly on the mineral nutrition level. The millet reacted most effectively to the application of mineral fertilizers, starting from the exit phase into the tube. The introduction of mineral fertilizers in pre-sowing tillage contributed to an increase in the proportion of legume components in the total green mass yield and a decrease in cereals. The highest competition in agrocenoses of millet with legume components was vetch, its share in the mixture increased, compared to the unfertilized background, by 6 and 14.5%, depending on the background of fertilizers. It was found that, compared with the unfertilized background, mineral fertilizers increased the yield of green mass from 1.5 to 4.9 tons per hectare, the collection of dry matter from 0.4 to 2.0 tons per hectare and the collection of feed units from 0.3 to 1.3 tons per hectare. Digestible protein content in 1 unit increased with the introduction of nitrogen fertilizer (N45), depending on the type of components in the mixture, from 3.2 to 6.6 g, and with the introduction of complex mineral fertilizer (N45P30K30) from 2.5 to 9.6 g. All are millet-bean mixtures at all levels of mineral nutrition comply with zootechnical standards.

In the results of research are presented the regularities of the formation of cenoses of segetal vegetation in field crops, in particular, corn for grain and soybeans, with adaptive tillage systems in the Forest-Steppe zone of Ukraine in order to develop effective, environmentally safe, resource-and energy-saving agrotechnological measures to control the level of contamination of agricultural land. The research was carried out during 2016-2020 in a stationary two – factor field experiment, which includes 5 alternative tillage systems (plowing, flat – cutting processing, differentiated – chiseling, shallow and surface – disking) and 3 fertilizer systems (without fertilizers; earning in the soil by – products of the predecessor; by-products + mineral fertilizers) in a short-term grain crop rotation (winter wheat-corn for grain-spring barley-soy) on gray large-sawn-light loamy forest soils.It was found that in agrocenoses of corn for grain and soybeans during the growing season, a small-year type of contamination is formed with a predominance of representatives of the Poaceae family, the monocotyledonous class, in particular Echinochloa crus-galli L. and Setaria glauca L.The best results in controlling of the development of segetal vegetation on experimental variants were provided by varieties of deep tillage (plow, flat-cut or chisel) against the background of an organic-mineral fertilizer system with the introduction of by-products of the predecessor into the soil and the introduction of mineral fertilizers. Such fertilizer systems decreased the contamination of crops by 38.9%.When cultivating the soil without turning the soil chunk – flat-cut and disking, against the background without fertilizers, the development of segetal vegetation was poorly controlled.Systems of minimized–shallow and surface disk treatments significantly (up to 88%) increased the abundance and (up to 91%) weight indicators of crop weed contamination in the pre-harvest period compared to multi-depth plowing and differentiated system of basic soil tilling.

Winter Wheat Varieties

The article shows the research on grain quality which was conducted at North- Caucasus Scientific Agricultural Center 2015-2017. The research explored the grain quality of new soft winter wheat varieties. The grain belongs to own selections of soft winter wheat, particularly to Sekletiya, Zernetko 1, Tsaritsa and Liniya 1517. The authors focus on indicating the impact of certain factors on high-quality grain. Batko variety was applied as a standard. The soil of the experimental plot was black soil; the climate was moderate continental. The forecrop was pure steam. Before sowing, the authors applied complex mineral fertilizers dosed N40P60K40; in spring the researchers fertilized them with ammonium nitrate dosed26 kgof ammonium nitrate per hectare. The authors observed positive correlation between nature and flour strength qualities of grain (0,7-0,8); inverse relationship between the value of natural mass and IIR values (-0,79); dough elasticity to dough extensibility (-0,88); and baking absorption parameter (-0,85). Flour strength depends on protein quantity and quality (r = 0.79). The wheat varieties have shown different values of flour strength: Liniya 1517 and Zernetko 1 correspond to good filler (282-294 a.), Sekletiya, Tsaritsa and Batko (standard) correspond to satisfactory improver (312, 332,345 a.). Tsaritsa variety formed gluten of the first group during three years under different temperatures. This indicates the prevalence of protein glutenin fraction and capacity of strong wheat improver. The authors found out high correlation coefficient of sedimentation with the amount of gluten (r = 0.81) was found. The quality of winter wheat grain was affected by the arid conditions of grain loading in 2015 and overwetting in 2017. This prevented the varieties from showing up their capacities.

The study was conducted to assess the impact of mineral fertilizers applied to the soil on the potassium level in the components of the “soil-plant” system of the sour cherry orchard. The experiment was conducted in the forest-steppe zone of the Central Russian Upland (Orel region) on loamy Haplic Luvisol during 2018-2020. The seasonal dynamics of exchangeable potassiumin the soil, the potassium status and productivity of sour cherry trees cv. ‘Turgenevka’ on the rootstock V-2-180 were studied in the orchard of 2015 planting. Fertilizers in the form of (NH2)2CO and K2SO4 were applied annually in early spring in doses of N30K40, N60K80, N90K120 and N120K160. It was found that a significant decrease in the level of potassium in the soil occurred during the period of intensive growth and crop formation, or after heavy precipitation. The use of fertilizers increased the content of exchangeable potassium in the soil (by 1.2-2.2 times), while the features of the potassium dynamics observed in unfertilized plots were preserved. Fertilizers contributed to the annual improvement of the potassium status of the leaves (by 0.05-0.24 % DW). The positive effect of fertilizers on the potassium content in fruits and the productivity of trees was manifested only in a year with prolonged intense precipitation (2020). The potassium content in fruits was 1.12-1.16 times higher than the control when applying N30K40, N60K80 and N90K120. A significant increase of tree productivity was found when applying N60K80 and N120K160 (by 54 and 69%, respectively).

Abstract The aim of the research is to study the effect of different backgrounds of mineral nutrition on the yield and quality of oilseeds of winter false flax in different regions of cultivation. The research was conducted in two contrasting regions: the forest-steppe of the Middle Volga region (Penza Research Institute of Agriculture) and the Central steppe zone of Crimea (Crimean Research Institute of Agriculture) in 2018-2020. The object of the research was the winter false flax varietal Baron. In the experiment, the effect of nitrogen fertilizer fertilization on the productivity of winter false flax at a dose of 0 to 60 kg of active substance per hectare with a step of 15 kg has been studied. Ammonium nitrate was used as nitrogen fertilizer. In the experiments of Penza Research Institute of Agriculture, the yield increase with nitrogen fertilizer was 0.07-0.19 t/ha. The highest yield of winter false flax was obtained in the variant with the introduction of nitrogen at a dose of N30, which was 1.61 t/ha, which significantly (0.19 t/ha) exceeded the variant without fertilizers. In the conditions of the Crimea, the yield of winter false flax in the average three years was not high and ranged from 0.95-1.16 t/ha. Fertilizing false flax with nitrogen at a dose of N30 led to an increase in yield by 0.21 t/ha, the productivity of the crop was 1.16 t/ha. Nitrogen fertilizer fertilization led to a slight decrease in the oil content of the seeds. In both regions, the fat content was greatest in the variant without fertilizer and was 39.9 and 40.9 %.

In 2014-2017  In the northern forest-steppe zone of the Chelyabinsk region The influence of planting dates and the depth of seed placement of potatoes on the size and quality of tubers was studied. During the study period, physical soil maturity in the first decade of May was observed twice in 2014 and 2017. The early planting of potatoes (May 5) was accompanied by an increase in the harmfulness of rhizoctoniosis (in the Rosara variety - by 22.8%, Kuzovok - by 63.7%) and the Colorado potato beetle (by 26 and 43%, respectively) compared with the May 12-15 planting. . The seedlings of the early variety of Rosara potato on May 30 in 2014 were damaged by frost (–1.0 ° C). From meteorological and phytosanitary positions, the optimum term for planting potatoes in this is the beginning of the second decade of May. Planting potatoes on May 12-15 with embedding of seed material to a depth of 5-6 cm ensured the formation of the planned yield of 40 t / ha with a planting scheme of 70x19 cm (Rosara - 41.4 t / ha, Kuzovok - 44.6 t / ha), and in the variety Kuzovok - additionally with the scheme 75x27 cm (38.3 t / ha). The planting of potatoes on May 25-29 provided a predetermined level of productivity (40 t / ha) of the Kuzovok variety in all variants of the experiment, and the Rosara variety in the variant of thickened planting. However, the starch content in Rosara tubers decreased by 1.60%, Kuzovok - by 1.26%, starch collection from 1 ha decreased by 0.60 and 0.37 t / ha, respectively, and the accumulation of nitrates in tubers increased by 25.8 and 52.5% compared with the optimal landing period. The advantage here was a deep embedment of seed tubers: an increase in the yield of the Rosara variety averaged 0.88 t / ha, Kuzovok - 1.23 t / ha. During the late planting period (June 5–12), there was a significant decrease in productivity (Rosara - by 3.49 t / ha, Kuzovok - by 5.18 t / ha) and the quality of potato tubers compared to planting from May 12-15. The starchy content of tubers decreased by 1.87 and 2.11%, the collection of starch from 1 ha to 1.10 and 1.45 t / ha, respectively, and the accumulation of nitrates increased 2.05 and 2.19 times. The planned yield of 40 t / ha was achieved only in the variety Kuzovok in thickened planting variants. At the same time, deep seeding of seed material increased the yield of the Rosara variety on average by 1.39 t / ha, and the Kuzovok variety - by 1.90 t / ha. Early landing (May 5) in 2014 and 2017. did not lead to an increase in potato productivity compared to planting in the second decade of May. At the same time, the yield decrease of the Rosara variety was 5.82 t / ha, Kuzovok - 2.75 t / ha. The planned yield of 40 t / ha was noted only in the variant of the thickened planting of the variety Kuzovok.
