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 %. Key words: fertilizers, biologicals, fungicide, yield, foliar feeding, plant protection.

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).

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.

In this article, the reaction of winter wheat varieties to fertilizers in irrigated soils in the varietal-soil-fertilizer system was studied and a feeding system was developed and recommended for each soil-climatic conditions and varieties. Appropriate fertilizer standards have been developed for each wheat variety, which have increased the germination, weeding, accumulation, tuberization, spike formation, dry mass accumulation, grain quality, and yield structure and yield of winter wheat. N250P200K200 kg/ha was obtained from Polovchanka variety of winter wheat at the rate of N250P200K200 kg/ha used in irrigated brown meadow soils, while in typical irrigated gray soils the yield of winter wheat was higher than N250P200K200 kg/ha of pure wheat with N250P200K200 kg/ha. Grain yield was 80.18 tons/ha from Tanya variety, 76.38 tons/ha from Krasnodar-99 variety and 82.32 tons/ha from Polovchanka variety under N200P150K150 kg/ha. Under the influence of the same optimal fertilizer standards, the growth and development of winter wheat, nutrient accumulation, and grain yield and grain quality are improved, and the efficiency of fertilizers is increased.

The problem to provide the livestock industry of the North-West of Russia with forage grain has sharply escalated since 2010. Its successful solution is connected with the level and validity of the use of mineral and organic fertilizers. The purpose of the study, started by the Menkovsky Branch of the AFI in 2012, was to find effective options for the use of new organic-mineral fertilizer (OMF) which provides maximum agronomic effect and can produce grain of high quality. The methodological basis was the micro trials in polyethylene vessels without bottoms of 1 × 1 × 0.4 m in size with an artificially formed upper part of the profile of degraded sandy sod-podzolic soil. The soil was of 4.75 рНKCl, 3.46 mmol (eq) of Ng per100g, 3.20 mmol (eq) of Sch per100g, 1.83% of humus, 217 mg / kg of mobile compounds of phosphorus and 92 mg / kg of potassium. In the course of research, there was high agronomic efficiency of its use for winter wheat and satisfactory agronomic efficiency of its use for barley. When the winter wheat variety ‘Moskovskaya 56’ was fertilized with 5 t/ha of organic-mineral fertilizer containing 2.46% of Ng, 4.51% of P₂O₅ and 3.36% of K₂O, grain yield increased in 2.6 times. Fertilized with N75P50K50 the productivity improved in 3.8 times with a payback of 1 kg of NPK 7.4 and 5.6 grain units, respectively. It has been established that the combination of OMF with mineral fertilizers is accompanied by a significant yield increase with a decrease in its relative contribution from 153% to 59% and from 143% to 105% and a payback of 1 kg of NPK from 3.8 to 2.6 and from 6.9 to 4.7 of barley grain units and winter wheat grain units, respectively. The best indicators of the agronomic efficiency of OMF, both when applied in pure form and when fertilized with N75P50K50, corresponded to a dose of 4 t / ha. It has been found that the addition of 10 kg of potassium (К₂О) per 1 ton to OMF provided yield increase on 15% and the payback period of 1 kg NPK increased from 6.4 to 8.4 grain units. Qualitative indicators of wheat and barley grain fertilized with OMF improved due to the rise of raw protein percentage on 8–27% and a number of ash elements, such as CaO (from 0.07 to 0.11 mg/kg), MgO (from 0.16 to 0.21 mg/kg), Zn (from 21.5 to 23.6 mg/kg).

The paper presents the results of research on the efficiency of technologies for cultivating spring wheat at various levels of intensity (extensive, intensive, resource-saving) under the conditions of chernozem soils of Kursk Region. It was found that higher reserves of available moisture and nitrate nitrogen in the arable layer of the soil before sowing spring wheat were provided by technologies with moldboard plowing. Replacing plowing with subsurface methods of tillage led to a decrease in the available moisture and nitrate nitrogen reserves in the soil for all fertilizer systems. The lowest weediness of spring wheat was observed when it was cultivated using technologies with moldboard plowing 52.3-58.3 PCs/m2, depending on the fertilizer system. The replacement of plowing with subsurface and surface tillage increased the weediness of crops to 61.7 and 73.7 PCs / m2, respectively. Application of mineral fertilizers had almost no significant effect on the number of weeds in spring wheat. The highest yield of spring wheat in all the years of studies (4,27 t/ha) was obtained in the intensive cultivation technology involving plowing at 20-22 cm, fertilization at a rate of N60Р60К60, treatment of crops with pesticides based on economic threshold of harmfulness. Yield of spring wheat, cultivated by resource-saving technologies with organic-mineral system of fertilization 0.86-4.25 t/ha depending on the methods of primary tillage. Moldboard plowing of the soil against the background of the organic-mineral fertilizer system increased the yield of spring wheat by 0.18 t/ha in comparison with subsurface tillage and by 0.39 t/ha in comparison with surface tillage. However, due to higher production costs, the best economic indicators were obtained when spring wheat was cultivated using resourcesaving technologies with an organic-mineral fertilizer system and non-moldboard methods of primary tillage.

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

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.

Висвітлено результати екологічної експертизи технологій вирощування пшениці озимої у північному Лісостепу за впливом на процеси міграції міді в генетичних горизонтах темно-сірого опідзоленого ґрунту та накопичення її у веґетативних і генеративних органах рослин. Результати екотоксикологічних досліджень дали змогу виявити, що мінеральна система удобрення та інтенсивний захист рослин можуть бути причиною нагромадження потенційно небезпечних шкідливих речовин у верхніх горизонтах ґрунту, а також сприяти їх міграції вниз за ґрунтовим профілем і створювати потенційну загрозу забруднення ґрунтових вод. The research was carried out on the basis of the Institute of Agroecology of the UAAS and the NSC «Institute of Agriculture of UAAS». Winter wheat variety – Lada Odes’ka. The soil of the experimental field is dark gray podzolized. The scheme of the experiment involved the study of fertilizer variants against the background of the minimal and intensive system of plant protection: control (without fertilizers), N60N30, P135K135 + N80 + N55, by-products, P90K90 + N60 + N30. The results of ecological examination of technologies of winter wheat growing in the Northern Forest-Steppe for the influence on the processes of copper migration in the genetic horizons of dark gray podzolized soil and its accumulation in vegetative and generative organs of plants are highlighted. The results of ecotoxicological studies have revealed that the mineral fertilizer system and intensive plant protection can cause the accumulation of potentially hazardous substances in the upper horizons of the soil. As well as promote their migration down the soil profile and create a potential threat to groundwater contamination. It was established that under the influence of mineral fertilizers (P135K135 + N80 + N55, P90K90N60 + N30, N45P45K45) intensive protection was carried out more active accumulation of potentially dangerous substances by vegetative (stem, leaves) by the organs of wheat. The use of by-products led to a decrease in the activity of these processes. Fertilizer systems, and especially plant protection, have had a significant impact on the redistribution of harmful substances between vegetative and generative organs of wheat. The amount of copper in winter wheat grains with intensive plant protection increased significantly. Prospects for scientific work in the future will be aimed at studying the influence of the transition of the transition of nickel, zinc from the soil into vegetative and generative organs of winter wheat and conducting an environmental assessment of technologies for growing winter wheat according to toxicological indicators.

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.
