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 use of biological products based on effective strains of microorganisms with a range of useful properties is one of the aspects of biological farming. The long-term field experiments were conducted in the soil and climatic conditions of the Crimea. А positive effect of the combined use of mineral fertilizers (NPK calculated at P30) and pre-sown inoculation of seeds (biopreparation based on L. nimipressuralis CCM 32-3) on the yield and quality of winter wheat grain was shown. The increase in grain productivity of winter wheat by 31 % compared to control (on average for 3 years) and grain quality indicators: protein and gluten – up to 12.5% and 28.0 % (in the control 9.9% and 19.2%, respectively) was revealed.

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.

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 %).

Purpose: to study the influence of methods and rates of mineral fertilizers on the winter wheat yield and grain quality by direct sowing on corn on ordinary chernozem under conditions of unstable moisture in Stavropol Territory. Materials and methods. The studies were carried out in 2014–2019 in a three-factor experiment in the fields of the North Caucasus Federal Scientific Agrarian Center. We studied the effect of pre-sowing fertilization and nitrogen fertilization (N52) on wheat productivity with two tillage technologies: with the recommended tillage system and with direct sowing (No-Till). Pre-sowing fertilization options: 1) without fertilizers; 2) N6P26; 3) N12P52; 4) N24P104; 5) N52P52; 6) N52P52K52; 7) N52; 8) N104P52K52. Results. Direct sowing had an advantage over the recommended technology in the reserves of productive moisture in the soil layer of 0–100 cm during the sowing period. In the No-Till technology, the average yield increase from pre-sowing fertilizer was within 0.78–3.02 t/ha (28–109 %), from nitrogen fertilization it was 0.55–1.85 t/ha (15–48 %) and when both methods of application are combined – 1.47–4.02 t/ha (53–145 %). The highest and most stable increments over the years (3.07–4.56 t/ha, or 101–219 % to the control) were obtained when using the maximum rate of pre-sowing fertilizer with nitrogen fertilization – N104P52K52 + N52. The increase in grain yield per unit of active fertilizer substance was 15.5 kg. Mass fraction of crude gluten in grain exceeded the control by 3.0–7.9 %. The application of this fertilizer dose helped to equalize the yield between technologies. Conclusions. The results showed that in order to obtain the greatest agronomic effect in the third year of direct sowing of winter wheat on maize, the predominant application of nitrogen fertilizer in a total dose exceeding the dose of phosphorus and potassium by 2–3 times is required. Correctly selected methods of application and fertilizers rates prevent a decrease in wheat yield when switching from the recommended tillage technology to direct sowing.

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.

Aim. To study the specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, yield and quality of winter wheat grain compared to granular nitrogen fertilizers in order to elaborate intensive produc- tion technologies. Methods. The content of mineral nitrogen in the soil was determined according to DSTU 4729-2007, the content of movable phosphorus and potassium forms − by Chirikov’s method (DSTU 4115- 2002). The abundance of the main ecological and trophic groups was registered after sowing the soil suspen- sion on dense nutrient media. The concentration of total nitrogen, phosphorus, and potassium in plant samples was determined according to the measurement procedure 31-497058-019-2005. The quality indices of grain, i.e. protein and crude fi ber content as well as general glassiness were determined using Inframatic 8600 NIR analyzer, Perten Instruments AB (Sweden). Results. The specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, the use of nutrients from fertilizers and soil, the yield and quality of winter wheat grain were demonstrated. Conclusions. The advantages of anhydrous ammonia application prior to sowing compared to the use of ammonia nitrate, traditional for Ukrainian agriculture after the growing season, were established.
