Through the period of 1977–2018, studies were conducted on three experimental fields of the Samara State Agricultural Academy with the purpose of studying the influence of the basic elements of the farming system on the weediness and the yield of winter wheat. Experimental schemes included the following options: the type of fallow in the crop rotation (black, seeded and green-manured), fertilizer systems (organic-mineral recommended, organic-mineral intensive and organic) and various methods and depths of soil tillage of fallow lands. Observations and surveys were carried out according to generally accepted methods. The soil of the plots was ordinary chernozem and typical medium-thick loamy chernozem (humus content was from 6.0 to 8.3 %, mobile phosphorus was from 90 to 155 mg/kg, exchange potassium was from 129 to 190 mg/kg, pHsalt was from 6.3 to 6.8). Replacing black fallow with seeded or green-manured fallow increased the weediness of crops 1.4–1.6 times and reduces the yield of winter wheat by 0.29–1.03 t/ha. Organic fertilizer systems significantly changed the weed species compositions and contributed to an increase in the number of perennials by a factor of 3.0, and their masses by a factor of 1.3–1.4 in comparison with organic-mineral fertilizer system. Organic-mineral fertilizer systems did not have a significant effect on the yield of winter wheat. The organic fertilizer system led to a slight (0.26–0.31 t/ha) grain shortage compared with organic-mineral. The methods and depths of soil tillage did not have a practically significant effect on the weediness and yield of winter wheat.

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

Agrarian science has faced the problem of is the humanity provision with food, the major part of which is provided by grain crops. Winter wheat the most fully uses the existing bioclimatic potential of the Ukrainian regions. The highest productivity of this crop can be obtained with the use of modern adapted varieties with high genetic potential of productivity taking into account the soil-climatic conditions of the zone, improvement and development of highly effi cient, scientifi cally grounded systems of nutrition and plants protection against harmful organisms. The article presents the results of the research conducted in 2017–2019 on dark brown medium-loam low-saline soils under the conditions of the experimental fi eld of State Enterprise Experimental Farm “Kopani” of the Institute of Irrigated Agriculture of NAAS of Bilozersky district of Kherson region. The infl uence of varietal characteristics, mineral and organic-mineral fertilizer system, biological and chemical methods of disease protection on the productivity of winter wheat plants was investigated. The fi eld, laboratory, mathematical and statistical methods were used in the experiment according to the generally accepted methods and guidelines in Ukraine. It was found out that the highest level of productivity was formed by wheat plants of Maria winter variety on the background of application of pre-sowing cultivation of mineral fertilizers at a N30P30 dose with the use of foliar fertilization with organic-mineral fertilizer ROST, solution (2.0 l/ha) at the beginning of the restoration of spring vegetation and in a stage of the fl ag leaf and chemical protection of plants using fungicide – Colossal, emulsion concentrate (1.0 l/ha). Thus, on average during the years of research, the grain yield in this variant was 4.96 t/ha, the number of productive stems – 411 pieces/m2, the number of grains in the ear – 27.6 pieces, the mass of 1000 grains – 51.5g. When using the chemical method of protection to control dark brown spotting (Drechslera sorociniana Subram) of winter wheat, the rate of development of the disease ranged 2.0–3.1 %, and the eff ectiveness ranged 83.1 – 89.4 %.

The studies were conducted at the experimental base of the Tatar Scientific Research Institute of Agriculture in 1996–2014 to adapt fertilizer systems and basic tillage to achieve yields of 3–5 t/ha. The article cited data on winter wheat – the second crop of the third rotation of the eight-field grain-grass-crop rotation for 2013–2014. We studied the effect of organomineral, organic, mineral fertilizer systems on the winter wheat yield using a differentiated approach to their use in combination with different primary tillage systems (dump plowing to the depth of the arable layer, multi-depth loosening and loosening to a depth of 15–16). The organomineral fertilizer system differed with the saturation with organic fertilizers of 7 t/ha of arable land per year + N36P32K60 according to the balance sheet for receiving 4 t/ha of grain with spring fertilizing using ammonium nitrate, where the yield was 4. 03 t/ha, and the saving on mineral fertilizers, depending on crop rotation and soil saturation with organic matter, was 25–35 %. The yield of winter wheat by the water-saving technology amounted to 4.03 t/ha with a planned level of 4.0 t/ha. At the same time, at the purchase price of 7 rubles/kg, the level of profitability rose to 195.85 %, the cost of 1 center of grain amounted to 236.6 rubles.

Influence of prolonged application of various fertilizer systems and periodic liming on the dynamics of redox potential (ROP) of light grey forest surface-gleyed soils under different crop rotations is presented in the research results. The obtained ROP indexes showed significant variability in variants of experiment depending on the fertilizer, lime and terms of determination in both fields of winter wheat and spring barley. The highest ROP values in variants with organo-mineral and mineral fertilizer systems with background of liming were observed in spring. They decreased during the period of maximum growth and development of winter wheat and spring barley together with the growth of microbiological activity and the intensity of CO2 release, and slightly increased before harvesting. It was established that the application of organo-mineral and mineral fertilizer systems with the background of liming with CaCO3 dose, calculated according to hydrolytic acidity, to the greatest extent increase ROP, especially during the period of intensive growth and development of plants. Compared to similar fertilizer system with the background of liming with a CaCO3 dose, calculated according to the pH- buffer capacity, it contributes to one-sided growth of oxidation processes and additional mineralization of humus. Thus, the organo-mineral fertilizer system with the application of 10 tons of manure per hectare of crop rotation and one norm of mineral fertilizers (N65P68K68) with the background of liming with CaCO3 dose, calculated according to the pH-buffer capacity (2.5 t/ha), contributes to rational use, preservation and fertility protection of light grey forest surface-gleyed soils, optimizing the redox potential during whole growing season of crops, and provides high yields. Studies have shown that during whole growing season of winter wheat and spring barley the lowest values of oxidation were obtained with the long-term use (for 50 years) of mineral fertilizer system with the introduction of one norm of mineral fertilizers only. It led to a decrease in the actual soil acidity to 4,03 pHKCl units and the increase of hydrolytic acidity to 5.11 mg-eq/100 g of soil. This once again emphasizes the importance of periodic liming of acid light grey forest surface-gleyed soils as a factor weakening the negative influence of mineral fertilizers. Key words: light grey forest surface-gleyed soils, redox potential, mineral fertilizers, manure, lime.

Under the conditions of the south-western part of the Central Black-soil region in the grain-and-plant crop rotation on the black-soil the typical maximum yield of winter wheat was 5.52 t/ha when using the organic-mineral fertilizer system as part of mineral fertilizers in the dose of N60P60K60 and manure in the dose of 40 t/ha according to the third level of plant protection (seed etching of herbicide fungicide insecticide growth substances) with maximum payback of 1 kg of mineral fertilizers with grain harvest increase – 15.5 kg. Yield increase at the 1st level of plant protection (seed etching) was 1.86 t/ha (68.1%), at the 2nd level of protection (seed etching of herbicide fungicide) – 2.55 t/ha (93.4%) and at the 3rd level of protection – 2.79 t/ha (102.2%). The highest increase from pesticides was 0.69 and 0.93 t/ha (15.0 and 20.3%), respectively. The use of such a fertilizer system is justified, in which the energy coefficient was 1.03 and 1.05. The design of an organic fertilizer system using manure does not meet the requirements of bioenergy efficiency at all levels of plant protection (Кee = 0.79-0.87).

Relevance of the research. Winter wheat is considered to be a leading cereal crop. One of the area of stabilizing this crop production is to intensify its cultivation on the drained soils of Polissya. Due to the changes in external factors (global and regional climate change, soils, etc.) and technology, the question of modeling the process of crop productivity formation remains relevant. Objective of the research was to evaluate the impact of climate change (increase of average air temperature) on the winter wheat yield on the drained lands of Western Polissya when applying different fertilizer systems. Research methodology. The research was conducted in a stationary long-term field experiment of the Volyn State Agricultural Research Station of NAAS. The following fertilizer systems were investigated: control (without fertilizers); organic fertilizer – green manure crop; mineral fertilizer - N60P60K60 + lime; organic-mineral fertilizer - N60P60K60 + green manure crop + lime. In the course of the study, a systematic analysis of long-term results of field experiments and meteorological observations using mathematical and statistical methods, correlation and regression analysis were used. Research results. The coefficient of yield variation over the years of research on a variant without fertilizers reached 27%, against 19% for the organic-mineral fertilizer system. Applying the fertilizers helped to reduce the variability of winter wheat yield by 19 - 23%. Correlation analysis of winter wheat yields in view of the average air temperature of the early spring period (from the second decade of February to the first decade of April) was 0.85. Low air temperatures in this period indicate the late dates of the beginning of spring crop vegetation, which negatively affected wheat productivity. Relatively high temperatures contribute to earlier spring processes and, accordingly, positively affected the yield formation. The correlation coefficient of the average air temperature and wheat yield in the spring-summer period (second decade of April - the second decade of July) was - 0.71. Conclusions. The highest efficiency on sod-podzoliс drained soils is provided by applying organic-mineral fertilizer system. The average wheat grain yield when applying this fertilizer system was 5,7 ton per hectare (+ 38% over control). The application of balanced fertilizer systems reduces the amplitude of grain yield fluctuations from 27% to 19%. The temperature regime in the period from the 2nd decade of February – till the 1t decade of April has a significant effect on the yield of winter wheat grains. Having the average temperatures over 5оC, yields increased by 1-1,5 ton per hectare, and on the contrary, rise of average temperatures in the spring-summer period more than 16оC significantly reduced this index. The established mathematical dependences enabled to estimate the projected winter wheat yield by the analysis of the temperature regime over the years. The conducted research and established features make it possible to calculate the projected winter wheat yields by the temperature regime of the period from the end of February till the beginning of April. The study of the interrelation between the crop productivity and the combined action of temperature and water regime is supposed to be the next stage of the research.
