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.

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 most important task at all stages of modern agriculture development is to increase the yield and quality of grain. Plant growth regulators can play a big role in this. The paper considers an impact of Polaris fungicide on winter wheat seeds and the use of growth regulator Melafen in winter wheat crops in Ufa region of the Republic of Bashkortostan are considered. The soil and climatic conditions of the growing season 2017-2018 years have influenced on formation of the yield and quality of winter wheat grain. Seed treatment with Polaris fungicide in combination with the crop care products provided productivity of 41.8-61.5 centner per hectare. The use of growth regulator Melafen in Ufa region of the Republic of Bashkortostan ensured an increase in crop yield up to 59.2-63.7 centner per hectare or 30.3-40.4%, depending on the processing scheme used. Determining the number of falls in the experience showed that this indicator fluctuated within 215-314 sec., which corresponds to the indicators for higher, first and second class of grain - a state of emergency more than 200 sec. In the experiment, the indicators of the nature of the grain had a value of from 671 to 758 g/l. The use of Polaris in the experiment contributed to the enhancement of the grain nature and reaching the level of the highest, 1.2 grade of grain. Due to the fact that in terms of quality group - all the options corresponded to group 2 of quality or grain of grade 3-5, the assessment of the quality of winter wheat grain shows that in the experience the quality of grain of all options corresponds to class 3.

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 %).

In winter wheat crops, the fight against weeds, together with the use of mineral fertilizers, which increase the yield and quality of the crop by reducing the removal of nutrients from the soil, is an urgent production task. The purpose of the research is to develop methods for increasing the yield of winter wheat with the combined use of herbicides and mineral fertilizers. Field experiments were carried out in the steppe zone of the Republic of North Ossetia – Alania in 2017–2019. The soil of the plot is chestnut calcareous. Weather conditions during the years of the research were favorable. The object of research is the high-yielding winter wheat variety Utrish. Mineral fertilizers stimulate the vital activity of soil microorganisms and enhance the cycle of biological transformation of plant nutrients, and herbicides have an inhibitory effect on cellulose-decomposing microorganisms, which ultimately reduces the rate of cellulose decomposition. Cellulose decomposed most intensively on backgrounds where mineral fertilizers were used. In control variant 3, the determination period, cellulose decomposed by 29.8%, against an average background (N60P60K60) by 40.2%, and against an increased background (N90P90K90) – 43.6%. Herbicide Grench at a dose of 10 g/ha on backgrounds without fertilizers and with fertilizers in different doses ensured the death of weeds during the growing season by 76.6 ... 89.2%. The herbicide Luvaram (1.6 l/ha) also provided high weed death – 56.4–62.6%. The application of a tank mixture (Grench 5 g/ha + Luvaram 0.8 l/ha) reduced weed infestation of winter wheat crops by 85.3–89.2% on different backgrounds of fertilization. The highest yield and profitability in the experiment were noted in the variant of the combined use of mineral fertilizers and herbicides. The level of profitability against the background of medium doses of mineral fertilizers (N60P60K60) was 130–150%, and against an increased background (N90P90K90) – 149–169%.

In the years 1999 to 2001 in conditions of small-plot field experiments was carried out on loamy degraded chernozems at the Plant Breeding Station of Sládkovičovo-Nový Dvor to solve the problems of topdressing winter wheat (Triticum aestivum, L.), variety Astella, with different forms of nitrogenous fertilizers. Nitrogenous fertilizers were applied at the growth phase of the 6th leaf (Zadoks = 29). Four various forms of fertilizers were exemined: urea solution, DAM-390, DAM-390 + Dumag, DASA. Different weather conditions statistically highly significantly influenced grain yield in respective experimental years. Topdressing with nitrogen (30 kg N.ha–1) caused statistically highly significant increase of grain yield in all fertilized variants ranging from +0.29 t.ha–1 (applied of DAM-390) to +0.69 t.ha–1 (applied of DASA) according to respective treatments. Average grain yield in unfertilized control variant represented 7.23 t.ha–1. Nitrogen nutrition showed positive effect on the main macroelements offtake (N, P, K, Ca, Mg, S) by winter wheat grain in all fertilized variants. Nitrogen fertilizing positively influenced formation of wet gluten and crude protein with highest increment in variant with DASA and variant with DAM-390 + Dumag.

The purpose of research: to improve the technology of growing flax in the Western region of Ukraine on the basis of the introduction of systems for minimizing tillage, which will increase the yield of trusts and seeds. Research methods: field, laboratory, visual and comparative calculation method. Research results: Field experiments included the study of three tillage systems (traditional, canning and mulching) and determining their impact on growth and development and yields of trusts and flax seeds. The traditional tillage system included the following operations: plowing with a reversible plow to a depth of 27 cm, cultivation with simultaneous harrowing and pre-sowing tillage. The conservation system is based on deep shelfless loosening of the soil and provided for chiseling to a depth of 40 cm, disking to a depth of 15 cm, cultivation with simultaneous harrowing, pre-sowing tillage. During the implementation of the mulching system, disking to a depth of 15 cm, cultivation with simultaneous harrowing and pre-sowing tillage with a combined unit was carried out. Tillage implements and machines were used to perform tillage operations: disc harrow BDVP-3,6, reversible plow PON-5/4, chisel PCh-3, cultivator KPSP-4, pre-sowing tillage unit LK-4. The SZ-3,6 ASTPA grain seeder was used for sowing long flax of the Kamenyar variety. Simultaneously with the sowing of flax seeds, local application of mineral fertilizers (nitroammophoska 2 c/ha) was carried out. The application of conservation tillage allows to obtain the yield of flax trust at the level of 3,5 t/ha, which is 0,4 t/ha (12.9 %) more than from the area of traditional tillage and 0,7 t/ha (25 %) in comparison with mulching. In the area with canning treatment, the seed yield was the highest and amounted to 0,64 t/ha. The difference between this option and traditional and mulching tillage reaches 0,06 t/ha (10,3 %) and 0.10 t/ha (18.5 %), respectively. Conclusions. Preservation tillage, which is based on shelf-free tillage to a depth of 40 cm and disking to a depth of 15 cm has a positive effect on plant growth and development, yield and quality of flax.

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.
