Relevance. Among the main problems of modern agriculture, the problem of reducing the biological yield of agricultural crops is particularly prominent. One of the most cost-effective solutions to this issue may be the use of organic fertilizers. Zoo compost is a type of organic fertilizer that is a product of the vital activity of fly larvae. To confirm the results of the suitability of zoo compost as an organic fertilizer, a field experiment was conducted.Results. It has been experimentally established that the zoo compost of Black lion fly larvae increases the survival rate of tomato plants, positively affects the growth of tomato plants, and accelerates fruit maturation. It has a positive effect on the formation of tomato fruits and yield. Analyzing the data obtained from the accounting area of the plot, we can conclude that the yield increase in relation to the control was in the range of 1.859–2.375 kg. It should be noted that the maximum yield increase was obtained by applying a double dose of zoo compost (2 tons per ha).

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 authors studied the influence of different methods of using micronutrient fertilizers on the yield of spring wheat grain and established standard agrochemical indicators of mineral nutrition on the grassland-chernozem soil of the Omsk region. Use was made of helated micronutrient fertilizers (zinc and copper). Chelated micronutrient fertilizers are an organic complex of a microelement with a chelating agent, in which the microelement is freely absorbed by the plant. The advantages of chelated micronutrient fertilizers are an increase in the availability of trace elements, because these compounds are entirely supplied to the leaf during foliar feeding or during pre-sowing treatment of seeds, protection against the formation of insoluble, inaccessible, economical consumption. The experiment established that the use of zinc and copper chelates in the cultivation of spring wheat in the forest-steppe conditions of the Omsk region is effective. The best rate of zinc and copper for pre-sowing seed treatment is 200 g/t. For foliar top dressing in the tillering phase, the best rate of zinc chelate is 20 g/ha, the most effective top dressing is copper chelate at a rate of 10 g/ha, as it is less expensive in terms of the amount of the applied product. Optimizing spring wheat nutrition by using zinc and copper chelates by foliar feeding of plants in the phase of stemming provided an average increase in yield from 0.03 to 0.16 t/ha of grain (1.4–7.3% compared to control). Experiments revealed a positive effect of zinc chelate in this phase of the yield development, when zinc was used at a rate of 20 g/ha, the greatest yield increase was obtained 0.14 t/ha (2.20 t/ha in control), when using copper chelate the maximum yield was obtained at a rate of 20 g/ha. To obtain a ton of yield in the best version of Zn200, spring wheat required: N – 35.7 kg, P2О5 – 21.9 kg, K2О – 22.6 kg, Zn – 47.56 g, Cu – 5.91 kg. When treating Cu200, the removal of nutrients amounted to: N – 33.9 kg, P2О5 – 21.8 kg, K2О – 22.1 kg, Zn – 54.03 g, Cu – 4.80 g. When carrying out foliar top dressing in the tillering phase of Zn20, the removal of nutrients from a ton of crop yield amounted to: N – 35.4 kg, P2О5 – 23.4 kg, K2O – 23.4 kg, Zn – 49.7 g, Cu – 4.87 g; in the Cu10 variant it was required: N – 34.3 kg, P2O5 – 22.5 kg, K2O – 23.6 kg, Zn – 52.9 g, Cu – 4.36 g. Foliar dressing in the booting phase at a rate of Zn20 was characterized by the following per-ton removal: N – 34.6 kg, P2О5 – 25.3 kg, K2О – 24.9 kg, Zn – 65.0 g, Cu – 5.13 g, treatment with copper chelates Cu20, the removal of nutrients amounted to: N – 34.7 kg, P2О5 – 24.4 kg, K2O – 25.9 kg, Zn – 61.1 g, Cu – 6.4 g. The element utilization coefficients from the soil (EUC) accounted for: nitrogen – 87%, phosphorus – 8.0%, potassium – 6.0%, zinc – 7.0%, copper – 2.0%.

The results of a study of the effectiveness of the joint application of potato mineral and organic fertilizers are presented. The studies were carried out in 2017–2018. on the drained lands of the Tver region. Objects of research - potatoes of the Scarb variety, mineral and organic fertilizers in various doses. Organic fertilizers are products of the processing of organic raw materials based on fermentation processes - multipurpose compost (KMN) and BiGuEM. Mineral fertilizers - ammonium nitrate, double superphosphate and potassium chloride. In the work we used experimental methods - field experiments and theoretical research methods - mathematical statistics. Evaluation of the optimal fertilizer doses showed that BiHuEM organic fertilizer at a dose of 3 t / ha, when used together with mineral fertilizers at a dose equivalent to 3 t BiGuEM, provided potato resistance to late blight compared to the version where KMN was used - almost 8% in 2017 and 12% - in 2018, and compared with the option without the use of fertilizers (control) - by 61% and 23%, respectively. This combination of fertilizers provided the maximum yield (both general and marketable) in comparison with the control by 45% when calculating both types of yield in 2017, and in 2018 by 38% of the total and 53% of the commodity yield. A greater increase in potato yield was also revealed in the variant with BiGueM in comparison with the variant of using KMN - by 4.5% and 5.7% in 2017 and in 2018 by 6.1% and 10%, respectively. An increase in the quality of potatoes was noted, which is confirmed by the low content of nitrates in them, as well as by the increased content of starch, which was especially noted in 2017 - 34.3 g / kg and 15.99%, respectively.
