The results of  a three-year field experiment to study the effect of mineral fertilizers and biopreparations with active strains of associative nitrogen-fixing microorganisms on the yield and quality of corn on the ordinary chernozem of the Lower Don are presented. The application of a combination of mineral fertilizers in a dose of N60P40K40 ensured high efficiency. The increase in grain yield compared to the control option was 1.85 t / ha, or 61.3%. The increase in yield after a bacterial preparation application with a strain of associative nitrogen-fixing microorganisms 2P-7 without mineral fertilizers was 40.1%,  after application of the biopreparation 2P-9 with nitrogen-phosphorus fertilizers in a dose of N30P40 - 55.3%. The greatest effect in protein harvesting was after application of N60P40K40 - 81.6%, after application of 2P-7 and 2P-9 - 51.9 and 55.6%, respectively. After their combined application with  nitrogen-phosphorus fertilizers it increased by  20.9 and 22.2%. The level of profitability varied from 17% after application of full mineral fertilizer to 69% under the influence of biological products of associative nitrogen-fixing microorganisms.

В статье приведены результаты исследований по изучению влияния минеральных удобрений и куриного помета на продуктивность клубней картофеля отечественной и зарубежной селекции. В исследованиях, проведенных в 2017-2019 гг. на черноземе выщелоченном в условиях Пензенской области, установлено, что при внесении куриного помета и минеральных удобрений повышается урожайность и качество клубней, что непосредственно связано с обеспеченностью растений питательными веществами. Применение куриного помета в дозе 2 т/га позволило повысить общую урожайность клубней исследуемых сортов картофеля на 22,6-29,5, товарных клубней на 24,3-35,5 по сравнению с вариантом без удобрений. Наибольшую урожайность наблюдали на вариантах с совместным применением мочевины в дозе N30 и сульфата калия в дозе К60 и на вариантах с совместным применением аммофоски в дозе N30Р30К30 и сульфата калия в дозе К30. Применение умеренных доз минеральных удобрений и куриного помета в дозе 2 т/га увеличивает не только урожайность клубней картофеля, но и содержание в клубнях сухого вещества, крахмала и нитратов, не превышающих значения ПДК. Совместное применение азотно-калийных и азотно-фосфорно-калийных удобрений с добавлением сульфата калия в дозах К60 и К30 позволяют улучшить качественные показатели клубней по всем изучаемым сортам.The article presents the results of studies on the influence of mineral fertilizers and chicken manure on the productivity of potato tubers of domestic and foreign selection. In the studies conducted in 2017-2019 on leached chernozem under the conditions of the Penza region, it was found that when chicken manure and mineral fertilizers are applied, the yield and quality of tubers increases, which is directly related to the supply of plants with nutrients. The use of chicken manure at a dose of 2 t/ha allowed to increase the total yield of tubers of the studied varieties of potatoes by 22.6-29.5, marketable tubers by 24.3-35.5 compared with the variant without fertilizers. The highest yields were observed in variants with the combined use of carbamide in a dose of N30 and potassium sulfate at a dose K60 and in variants with a combined use of ammophos at a dose N30P30K30 and potassium sulfate at a dose K30.The use of moderate doses of mineral fertilizers and chicken manure at a dose of 2 t/ha increases not only the productivity of potato tubers, but also the content of dry matter, starch and nitrates in the tubers, not exceeding the MAC value. The combined use of nitrogen-potassium and nitrogen-phosphorus-potassium fertilizers with the addition of potassium sulfate at doses of K60 and K30 can improve the quality indicators of tubers for all studied varieties.

The problem of reducing crop yields during the transition from classical technology of cultivation to the technology without tillage (no-till) can be solved by the most effective use of fertilizers. The purpose of the research was to study the influence of mineral fertilizers on the yield and quality of winter wheat grain under direct sowing in the Stavropol Territory. Studies were carried out in 2015-2019 on the experimental field of the North Caucasus Federal Agricultural Research Centre. Winter wheat was sown using two cultivation techniques for growing crops with and without disturbing the soil through tillage. Preceding crops – pea and sunflower. Fertilizers were added to the rows simultaneously with the Triticum vulgare L. sowing; topsoil dressing was carried out using N52 according to the method of splitting dividers. Options (amount of fertilizers added to the rows): 1. Without fertilizers; 2. N6Р26; 3. N12Р52; 4. N24Р104; 5. N52Р52; 6. N52Р52К52; 7. N52; 8. N104Р52К52. In the third year of direct sowing (2017–2019), winter wheat showed high responsiveness to the addition of all doses of fertilizers in rows. The yield increase in case of pea being preceding crop varied between 0.76-3.06 t/ha; sunflower – 0.51–2.75 t/ha. N104P52K5 contributed to the highest and most stable yield – 6.89 t/ha and 5.92 t/ha after pea and sunflower, respectively. The increase from 1 kg of the active substance of the fertilizer was 14.7 and 13.2 kg of grain. The use of this dose of fertilizer minimized crop losses compared to the first year of wheat cultivation using no-till farming and classical agricultural technique. At the same time, the 3rd and 4th class grain was formed. Higher content of raw gluten compared to other doses of fertilizers was noted likewise: 1.6–9.8 % (preceding crop – pea) and 1.1–11.5 % (preceding crop – sunflower) more. Nitrogen fertilization played a significant role in increasing yields only after sunflower (the average increase was 0.21–0.86 t/ha).

The article presents the results of research performed in a field stationary experiment on leached chernozem. In soy sowings of the Mageva variety, studied was the effectiveness of joint and separate application of various doses of mineral fertilizers and chelated form of microfertilizers (ZhUSS-2) in variants with soil previously limed in 0.5 and 1.0 h.a. The analysis of crop yield showed that the value of this indicator was significantly influenced only by mineral fertilizers, which provided an increase from 0.05 to 0.37 t/ha. as compared to the variant without fertilizers (0.89 t/ha, LSD05 0.05 t/ha). An increase in the level of nitrogen nutrition from 45 to 60 kg a. i. / ha did not contribute to a significant increase in soybean productivity and reduced the payback of 1 kg of a. i. nitrogen by grain from 7.11 to 5.44 kg. The content of crude protein in soybean grain significantly increased as the result of the aftereffect of liming of the soil in 0.5 h.a. by 0.79 % (LSD05 0.33 %), of ZhUSS-2 preparation use ˗ by 0.19 % (LSD05 0.16 %) and of mineral fertilizers use – by 0.26-4.02 % (LSD05 0.22%). When full mineral fertilizer was applied, the concentration of crude fat decreased by 0.53-0.62 abs. %. Considering unfavorable weather conditions for sowing soybean crops on leached chernozem it is possible to recommend the application of mineral fertilizers in doses of N30P50K80 and N45P50K80 together with treatment of crops with ZhUSS-2 preparation.

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.
