Aim. To study the features of phosphorus nutrition of winter wheat under the infl uence of different doses of mineral fertilizers and microbial preparation Polimiksobakteryn. Methods. The phosphatase activity in rhizo- sphere soil of winter wheat was determined photocolorimetrically by the method of Geller and Ginsburg, the phosphorus content in plants – as described by Denizhe in the modifi cation of Bouvatier. Results. The phos- phatase activity in the rhizosphere soil of winter wheat plants increases due to the application of a microbial preparation and mineral fertilizers in low doses. This increases both the absorption of phosphorus by plants and their yield. Conclusions. Growing winter wheat on the leached black soil with dose-relevant introduction of mineral fertilizers in doses, not exceeding N[60] P[60] K[60] , and the use of Polimiksobakteryn improve phosphorus nutrition of wheat plants and promote the increase in the yield of crops.

The changes in labile phosphorus compounds content during germination of wheat were investigated. These compounds were determined in acid-soluble germ extracts separated into fractions according to the solubility of their barium salts. Low germination temperature was found to raise the labile phosphorus content in the fraction of insoluble barium salts. If we assume that labile P of this fraction consisted mainly of adenosinedi- and triphosphates, it would seem that the rise, in the ATP and ADP level under the influence of low temperature may be essential for initiating flowering in winter varieties.

The paper depicts the study of mineral nitrogen and pre-sowing seeds bacteryzation on the development of nitrogen fixing bacteria and the activity of autotrophic and heterotrophic nitrification. It was revealed that nitrification activity in the root zone of winter rye plants rises together with the increase of mineral nitrogen doses. Heterotrophic nitrification plays a significant role in the formation of nitrate pool in the root zone, especially during the early stages of plants organogenesis. Application of the microbial preparation Diazobakteryn had enhanced the activity autotrophic and heterotrophic nitrification processes in the rhizosphere soil of plants in the spring, during the early stages of their development while during the next organogenesis phases the reduction of nitrification processes was observed. In plants-free soil the contribution of heterotrophic nitrification to biological transformation of nitrogen was negligible.

Aim. Verification of scientific concepts regarding the spatial heterogeneity of field agrocenoses. Identification of the variability of phytometric and structural crop ndicators and determination of the degree of their influence on the yield and quality of winter wheat grain in the steppe zone of the Orenburg Urals.Material and Methods. Establishment of field experiments, related observations and counts in accordance with the methodology of state variety crops testing and B.A.Dospekhov's guidelin. Monitoring of winter wheat crops was carried by measuring the vegetation index (NDVI) with a Green Seeker Handheld Crop Sensor, Model HCS‐100 (Trimble, USA). Determination of grain quality indicators was conducted according to GOST 9353‐2016 Wheat – Technical Conditions. Microsoft Office Excel was employed for the correlation and regression analysis of experimental data. Results. Analysis of the intra‐field heterogeneity of winter wheat agrocenoses in terms of yield and grain quality was conducted. The dependences of yield and grain quality on the principal crop phytometric and structural parameters were defined and expressed in the form of regression equations.Сonclusion. The results of the studies attest to the growth of reserves of grain yield to 3.0 t/ha and grain quality to class I‐II class in zonal climatic conditions of optimization of environmental factors to the level of the best basic plots by levelling out field soil heterogeneity. This is possible by restoring the fertility of anthropogenically‐degraded soil through the introduction of landscape‐adaptive and resource saving farming systems, soil protective and soil restorative crop rotation, differentiated application of organic and mineral fertilizers and selection of the most adaptive varieties. We also advise the introduction of intelligent ‘digital technologies’ aimed at fuller implementation of the genetic potential of cultivated varieties with careful consideration of natural resources and the preservation of biological diversity.

Field experiments were conducted in 2017-2020 on the southern black soil in the conditions of the Lower Don. The Doneko winter wheat variety was sown. The predecessor of wheat is corn for grain. Mineral fertilizers were represented by ammonium nitrate (34.4%), nitroammophosk (16-16-16) and carbamide (46%), which acted as a background option in the scheme of the ex-periment. Organomineral fertilizers were preceded by the following agrochemicals: Ruther, Leyli 2000, Alga 1000/Turbo, Siamino Pro, Gumiful Pro, Soft Garden (Master Green Mix) and Double Vine (Monocaliphosphate). In the experiment, options for the joint use of non-root application and pre-sowing seed treatment with organomineral fertilizers were also studied. It was found that the use of organomineral fertilizers Ruther (0.5 or 0.25 l/ton) and Leyli (0.25 l/ton) for seed treatment before sowing, the use of Soft Guard (0.2 l/ha) and Humiful Pro (0.2 l/ha) in spring tillering and in the flag leaf phase against the background of a starter treatment mineral fertilizer in the form of azofoska at a dose of N32P32K32, fertilizing on frozen-thawed soil with ammonium nitrate at a dose of N40 and non-root topdressing with carbamide in the phase, earing at a dose of N20 increased the increase in grain yield on average for 3 years compared to the control variant (farm fertilizer system) by 0.73 t/ha or by 23.0%. The greatest increase in yield from the Router root-forming agent used for seed treatment was 0.36 t/ha or 11.3%. Keywords: WINTER WHEAT, MINERAL FERTILIZERS, ORGANOMINERAL FERTILIZERS, YIELD

Purpose: to reveal the effect of different doses of mineral fertilizers (MF) on the growth, development and productivity of soybeans on meadow-chernozem soils of Rostov region. Materials and methods. The studies were carried out on meadow-chernozem soils of Oktyabrsky district Rostov region in 2019–2020. Observations of the effect of different doses of MF on the growth, development of plants, yield records, statistical processing of the results were carried out according to generally accepted methods of conducting field experiments. Results. It was found that, on average for 2 years, the greatest plant growth was observed in the variant with the calculated MF dose for the planned yield of 5.0 t/ha. The height of plants in this variant in the branching phase averaged 24.8 cm for 2 years, in the flowering phase – 54.7 cm, and in the phase of bean filling – 117.6 cm. This is, respectively, 23, 21 and 13 % higher than the control. The largest increases in leaf surface area in this variant were revealed: on average for 2 years, they amounted to 13% in the phases of branching and filling of beans and 18 % in the flowering phase. At the same time, in the variant with the MF dose for the yield of 4.0 t/ha, the increments to the control were respectively equal to 9, 16, 13 %, and in the variant with the MF for the yield of 3.5 t/ha – 6, 12, 8 %, respectively. Similar changes were revealed in the accumulation of dry aboveground biomass. Conclusions. The greatest impact on the height of soybean plants was exerted by the application of MF with a dose calculated for the planned yield of 5.0 t/ha. On average, for 2 years, the height of plants in this variant was 117.6 cm in the phase of filling the beans, which is 13 % higher than in the variant without fertilizers. The same tendency can be traced when determining the leaf surface area and accumulation of dry biomass according to the options in the observation phases. Thus, the best conditions for the yield formation were formed in the variant with the calculated dose for the planned yield of 5.0 t/ha. As a result, on average for 2 years, the soybean yield in this variant is 109 % higher than the control.

We studied the cellulolytic activity of the winter wheat rhizosphere soil in a stationary field experiment with the application of mineral nitrogen-phosphorus fertilizers (N15P23 per hectare of crop rotation area), straw, and seed inoculation. We estimated the crop yield depending on the intensity of cellulose decomposition in the soil. We established that the intensity of cellulose decomposition in the rhizosphere of winter wheat was most affected by the application of mineral fertilizers, as well as the combination of the application of mineral fertilizers, straw, and seed inoculation with the biopreparation rhizoagrin before sowing.
