The article presents the results of field studies conducted in 2018-2020 on the leached chernozem of the Volga foreststeppe. The objects of the research are the varieties of spring wheat Tulaykovskaya 10 (control), Yoldyz and Tulaykovskaya 108. At seeding rates of 5.0 and 5.5 million viable seeds per 1 ha the effect of mineral fertilizers was studied. The fertilizers were represented by a complete NPK mineral fertilizer of 16 kg a.i. and by top-dressing with mineral nitrogen fertilizer in the tillering phase at the doses of 30, 60 and 90 kg a.i./ha against this background. An increase in the seeding rate of seeds from 5.0 to 5.5 million seeds per 1 ha led to a significant increase in the yield of spring wheat in all years of study (by 0.11-0.26 t/ha), the weight of 1000 seeds – by 1.44 g (LSD05 = 1.14), the nature of grain - by 8 g/l (LSD05 = 5). The effect of top-dressing with nitrogen fertilizers has been proved – the increase in yield ranged from 0.15 to 0.28 t/ha over three years on the average, the maximum from a dose of 60 kg a.i. A statistically significant increase in the weight of 1000 seeds was provided by nitrogen fertilization in doses of 60 and 90 kg a.i./ha – by 2.79 and 1.87 g, respectively (LSD05 = 1.47), grain nature increased at doses of 30, 60 and 90 kg a.i./ha by 34, 23 and 16 g/l, respectively (LSD05 = 2). The average yield of spring wheat varieties with the selected combination of factors (5.5 million seeds/ha, N60) was in the range of 2.64-2.70 t/ha with a mass of 1000 grains 44.03-44.56 g, the nature of grain 765-783 g/l. The studied varieties differed in responsiveness to nitrogen fertilization (N60 against the NPK background): Tulaykovskaya 10 (+0.43 t/ha), Tulaykovskaya 108 (+0.39 t/ha), Yoldyz (+0.24 t/ha). Increases in yield from an increase in the seeding rate were 0.20 (Yoldyz), 0.25 (Tulaykovskaya 108) and 0.26 t/ha (Tulaykovskaya 10). In general, according to the experiment relative to the control variety Tulaykovskaya 10, the variety Yoldyz stood out with a stable increase in yield over the years of research (+0.08 t/ha), statistically significant in years with insufficient moisture. The Yoldyz variety was distinguished by an increased profitability of cultivation – up to 59.4 % at a seeding rate of 5.5 million viable seeds/ha against the background of applying mineral fertilizers N16P16K16 for pre-sowing soil cultivation.

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.

The study of the effect of the chelate complex “Akvarin 5” on grain productivity and quality was conducted on sodpodzolic soil in 2017-2019. The objects of the study were the spring wheat varieties ‘Daria’ (a standard), ‘Sudarynya’, ‘Ladya’, ‘Kamenka’. The purpose of the study was to determine the efficiency of the water-soluble mineral fertilizer with a complex of microelements “Akvarin 5”, produced by the local industry, on grain productivity and quality of various spring wheat varieties. The highest grain productivity was obtained with the use of mineral fertilizers in combination with additional fertilizing of 3 kg/ha of “Akvarin 5”. The productivity increase was 0.53–0.64 t/ha with 0.19–0.24 t/ha of НСР0.5 in comparison with the control. Spring wheat additional fertilizing with water-soluble fertilizer in its pure form increased protein in grain on 0.27–0.94% in comparison with the control, and when fertilizing “Akvarin 5” according to the N26P38K38 background, this indicator increased to 9.69–11.09%. When treating sowings with 1.5 and 3.0 kg/ha of “Akvarin 5” in its pure form, gluten content in grain increased to 18.71–20.30% in all varieties (in the control it was 17.71–18.91%). Treating of growing plants with “Akvarin 5” against the background of mineral fertilizers promoted the varieties to form grain with 19.89–21.26% of gluten. When treating spring wheat sowings with the water-soluble complex “Akvarin 5”, the cost of grain reduced by 14.4–17.5%, profitability raised on 17.7–22.6 in comparison with the control.

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.

Abstract The formation of spring wheat biomass on sod-podzolic soil is carried out mainly due to soil nitrogen, the share of which reaches 1/3 of the total removal of the element when using mineral fertilizers. Inoculation of spring wheat seeds with biologics of rhizosphere microorganisms increases the nitrogen content of fertilizers to 7.3%, increases its immobilization by 5.9-6.7% and reduces losses by 7.4-13.9%. The stability of the agroecosystem is characterized by nitrogen flows. During the growing season of spring wheat with a hydrothermal coefficient of 1.55-1.72, the amount of mineralized nitrogen (mineralization (M)), depending on fertilizers, reaches 9.4-11.1 g/m2, while the reimobilized nitrogen (reimobilization (RI)) – 2.2-3.1 g/m2, net-mineralized (net-mineralization (N-M)) – 6.8 - 8.0 g/m2. The use of nitrogen fertilizers and biological products leads the agroecosystem to the resistance mode (the maximum permissible level of exposure) (RI : M = 27-28%, N-M : RI = 2.5-2.7).

Abstract The most effective doses of the modified organic-mineral fertilizer (MOF), produced from non-contact pig manure in the conditions of the Rostov region for the purpose of soil reclamation, were determined. Experimental studies were carried out to determine the most effective dose of MOF based on non-contact pig manure. The dependence of the spring wheat yield on the use of a modified organic-mineral fertilizer based on liquid waste from pig farms fermented bird droppings and mineral fertilizers is determined. The equivalence of the effect of a modified organic-mineral fertilizer based on liquid waste from pig farms and fermented bird droppings, introduced in an equivalent dose, on plant biomass was established. When comparing the effects of different types of fertilizers, their toxicity was not established. The introduction of a modified organic-mineral fertilizer based on liquid waste from pig farms at a dose of 2 t / ha provided the highest biomass yield of 34-day-old plants of spring wheat of the “Zlata” variety, which reached 0.9 g/vessel and was 28.5% higher than the control value. A new organic mineral fertilizer with a pH of 8-10, with an organic content of up to 73% per dry weight, can be used for supporting the quality of liming and improving soil.

The article presents the effectiveness of the influence of certain agrotechnical components of the technology of growing wheat wheat in the conditions of the Right Bank Forest-steppe of Ukraine. The positive influence of application of foliar fertilization of crops is shown. The prospects of using the complex application of intensification elements are determined. It has been established that the optimization of the mode of power provides a more complete disclosure of the resource potential of plants, which increases yields. Reindeer nutrition should be considered as an element of supplementation to the soil nutrition system, primarily due to the fact that plants are able to absorb nutrients through the leaf surface only in limited quantities, with excess concentration of which possible burns or intoxication of plants. The use of foliar feeding on the background of the main fertilizer has been found to have a positive effect on productivity and quality. The role of the plant nutrition system, which allows to control the formation of grain productivity of spring wheat crops, is substantiated. It has been found that the optimization of the nutrition regime provides a fuller disclosure of the resource potential of the plants, thereby increasing the yield. Nutrition optimization provides more complete disclosure of plant resource potential, thereby increasing yields. It is determined that under the conditions of the Forest-Steppe of Ukraine the level of spring wheat yield is largely determined by the amount of rainfall that has fallen during the growing season. By optimizing the wheat's nutritional conditions, its productivity increases substantially, regardless of weather and climatic conditions. The use of mineral fertilizers, especially nitrogen in combination with phosphorus and potassium, can significantly improve the nutritional regime of the soil. The available nutrients of the plant are provided as a result of the mineralization of organic compounds by soil microorganisms and the transition of soluble mineral substances into solubility. This creates a more favorable environment for the growth and development of plants and for maintaining high soil fertility. At the end of the spring wheat vegetation, there was a redistribution of nitric and ammoniacal forms of nitrogen. It is advisable to continue research in this area and to deepen in connection with the emergence of new varieties, preparations and changes in climatic and soil conditions. Key words: spring wheat, yield, variety, sowing dates, seeding rate.
