Abstract. The goal is to study the influence of the predecessor and fertilizers on the yield and quality of winter wheat grain. Methods. The studies were carried out in a long-term stationary field experiment on a gray forest medium loamy soil. Field experience, observations, accounting and generalization of research results were carried out in accordance with the methodological recommendations of B.A. Dospekhov. Statistical processing of the research results was performed using Microsoft Excel 2007 with a 95 % significance level of the results. Results. As a result of the studies, it was noted that the studied predecessors had an insignificant effect on the development of winter wheat plants in the initial phases of growth. The density of winter wheat plants during the germination period varied within the range of 314–323 psc/m2 without the use of fertilizers and 317–328 psc/m2 against the background of their application. Further growth and development of plants took place in close relationship with the studied factors. At the end of the growing season, the number of productive stems was higher on the plots, where the clover of the first year of use was used as a predecessor, both in the control (without fertilizers) and when applying mineral fertilizers. Accordingly, the yield of winter wheat grain was higher for this predecessor, averaging 35.7 c/ha for 2014–2019. Without fertilization, depending on the predecessor, 25.2–32.8 c/ha were obtained, against the background of fertilization – 34.2–39.6 c/ha of winter wheat grain. On average, over the years of research, winter wheat grain contained 10.7–14.0 % protein. Depending on the year, this indicator varied from 8.8 % to 16.8 %. At the same time, the lowest values for the protein content were obtained for the variants without the use of fertilizers. In general, the content of protein and gluten in winter wheat grain largely depended on the application of mineral fertilizers and to a small extent on the predecessor. The weight of 1000 grains, depending on these factors, changed insignificantly.

This study evaluated how organic manures and mineral fertilizers affect winter wheat grain and straw yields and grain quality properties. The analysed period of the long-term fertilizer experiment was established in Čáslav, Czech Republic, in 1955 and covers the seasons 2011–2014. The fertilizer treatments were: control; farmyard manure (FYM); FYM + P; FYM + K; FYM + PK; FYM + N<sub>1</sub>; FYM + N<sub>2</sub>; FYM + N<sub>1</sub>PK; FYM + N<sub>2</sub>PK and FYM + N<sub>3</sub>PK. The highest grain yields were recorded in the FYM + P and FYM + N<sub>3</sub>PK treatments (8.9 t/ha). The highest straw yields were recorded in the FYM + N<sub>3</sub>PK treatment (6.52 t/ha). The lowest yields were provided in the unfertilized control and FYM treatments. Qualitative parameters were evaluated in the control, FYM and FYM + N<sub>3</sub>PK treatments between the years 2011 and 2013. The best quality of wheat grain was provided by the FYM + N<sub>3</sub>PK treatment. Combination of the farmyard manure with NPK is the best way to achieve high grain yields with good quality and leads to sustainable food production.

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.

Direct Sowing

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 research was carried out on the experimental field of FSBEI HE Ulyanovsk SAU in 2017-2019. The purpose of the research was to identify the influence of agroclimatic conditions in the region on the formation of yield and quality of winter wheat grain Saratovskaya 17 against various doses of mineral fertilizers. The experience scheme provided 4 options: 1. Control (without fertilizers); 2. N20P20K20; 3. N40P40K40; 4. N60P60K60. It was found that precipitation during the resumption of vegetation-flowering had a significant impact on the yield of winter wheat grain (R2=0,78). To characterize the humidification of the territory, hydrothermal coefficient was calculated according to G. T. Selyaninov. In 2019, it was 0.21, which characterizes the period as very dry. In 2017 and 2018 weather conditions for winter wheat were more favorable (SCC 0.92 and 0.75-insufficiently moist). An increase in yield was observed at a SCC of 0.92 (2017) in all variants of the experiment. The correlation coefficient between the yield of the studied crop and the SCC indicator was 0.84, which indicates a significant dependence of winter wheat productivity on hydrothermal conditions that develop during the period from the resumption of vegetation to flowering of the crop. It is important to note that the main factor affecting the accumulation of gluten in winter wheat grain Saratovskaya 17 and changes in its elastic-elastic properties are the conditions of mineral nutrition of plants. The coefficient of determination shows that 60% of the gluten quality was determined by the conditions of plant nutrition and did not depend on the prevailing weather conditions.

Wheat Cultivation

In modern agriculture, resource-saving technologies for cultivating grain crops and their optimization are becoming more and more relevant. The use of scientifically-based crop rotations, tillage methods and doses of mineral fertilizers allow increasing economic efficiency of winter wheat cultivation. The purpose of the research was to assess the yield and quality of winter wheat grain depending on different doses of mineral fertilizers under non-moldboard soil tillage in the crop rotations of the Central Chernozem Region. The research was carried out in 2012-2020 in a stationary multifactorial field experiment in Federal Agricultural Kursk Research Center. The experimental design included the following options: Factor A – crop rotations (grain-fallow-row, grain-grass-row, grain-grass); Factor B – mineral fertilizers (without fertilizers, N20P40K40, N40P80K80 kg ha-1). The soil of the experimental site is represented by typical, medium-loamy chernozem. The paper shows that the yield of winter wheat grain in the context of non-moldboard soil tillage was higher in the grain-fallow-row crop rotation and amounted to 3.34 t ha-1. In the grain-grass-row and grain-grass crop rotations, yield decreased by 6.6 % and 10.2 %, respectively. The maximum grain yield (3.98 t/ha-1) was obtained in grain-fallow-row crop rotation with N40P80K80. An increase in fertilizers doses led to protein and gluten content increment from 12.6 to 13.3 % and from 22.8 to 25.6 %, respectively; however, the differences in crop rotations were within the limits of experimental error. The grain nature varied according to the studied factors from 708 to 735 g/l-1 and was higher in the grain-fallow-row crop rotation with a dose of mineral fertilizers N40P80K80. Despite more significant net income after increased fertilizers dose (N40P80K80), the increase in the winter wheat grain yield did not allow obtaining a higher level of profitability compared to N20P40K40. Winter wheat cultivation in grain-grass-row crop rotation with N20P40K40 was the most cost-effective. In this variant, the cost of grain was the lowest (4.92 thousand rubles t-1); the profitability, on the contrary, was the highest (103.4 %).

Assimilation of basic nutrients from soil and mineral fertilizers of grain wheat on the black grain of the podzolized sand of the Right-bank Forest-steppe of Ukraine The effect results of prolonged use of different doses and ratios of fertilizers on chernozem podzolized in a field crop rotation under the conditions of Right-Bank Forest-steppe of Ukraine on the content of essential nutrients in winter wheat grain and straw, the precursor of which was soybean, were shown. It has been found that, due to different doses, ratios and types of fertilizers, the nitrogen content of winter wheat grain increased by 13–49%, phosphorus by 3–19%, and potassium by 6–14%. With grain, winter wheat absorbs nitrogen most – 49.4–147.8 kg/ha and phosphorus – 22.1–51.9 kg Р2О5/ha, and potassium – only 15.0–32.6 kg K2О/ha, depending on yield and quality. It is estimated that 27–33% of nitrogen, 35–36% – of phosphorus and 74–76% of potassium are returned to the soil with winter wheat straw from economic removal depending on fertilizer doses. Keywords: winter wheat, podzolic heavy clay loam chernozem, content of nitrogen, phosphorus and potassium, economic removal.

The research aims to establish the eff ectiveness of granular chalk use produced by «Slavuta-Calcium» Ltd. under growing Poliska–90 winter wheat variety, changing the physicochemical properties of grey forest soil and the wheat productivity. It also aims to establish optimal dosis of «Slavuta-Calcium» granular chalk as the meliorant and mineral fertilizer for grey forest soil in the system of winter wheat fertilization. In the temporary fi eld studies, various doses of nutrients N60–90–120P30–45–60K60–90–120 combined with «Slavuta–Calcium» granular chalk in a dose of Ca230–460–690 kg/ha of the active substance were studied against the background of secondary plowing of rotation products – soybean biomass that averaged 2.34 t/ha. Granular chalk is a modern complex highly eff ective meliorant with the content of Ca – 37.7 and Mg – 0.2 %, the mass fraction of carbonates (CaCO3 + MgCO3) makes at least 95 %. It is characterized by a high level of solubility when interacting with moisture in soil. It has a form of white granules, the mass fraction of 4.0–6.0 mm in size granules makes not less than 90 % and the one of 1.0 mm in size makes less than 5 %. Reactivity – 97 %. The granular chalk is advisable to apply on acidic soils, as a highly concentrated calcium-magnesium fertilizer, with the former as the dominant fertilizer, to optimize the physicochemical properties of the soil, as well as the plant nutrition system, in particular, increasing the availability of an element for assimilation by plants and as long-term ameliorants. The eff ectiveness of the use of mineral fertilizers, in particular acidic nitrogen on highly and medium acidic soils, after chemical reclamation is increased by 30–50 %, and slightly acidic by 15–20 %. The increase in productivity of crops from the combined eff ects of nutrients and chalk granulated is usually higher than when separately applied. The eff ectiveness of the integrated action of these elements is manifested in the growth of plant productivity and the quality of the resulting products, as well as the optimization of physical chemical properties and soil buff ering in the long term. In order to optimize the physicochemical properties of the arable layer of gray forest soil and the productive nutrition of agricultural crops, winter wheat, in particular, biogenic elements should be used in doses N60-90-120P30-45- 60K60-90-120 with granulated chalk «Slavuta-Calcium» in doses of Ca230-460-690 kg/ha of active substance. Granulated chalk obtained as a result of industrial grinding of solid sedimentary carbonate rocks of natural origin, subsequently under the infl uence of the granulation process of the starting material contains Ca and Mg carbonates of at least 95 %, dense granules which facilitates convenient mechanized application, as well as chalk suitable for accurate metered application on the quest map. Key words: granular chalk, gray forest soil, chemical reclamation, crop productivity.
