In the conditions of the Stavropol Krai arid region the single nutrient fertilizer treatment of winter wheat does not always justify the costs expended due to the moisture deficit during the growing season. In this regard, one of current promising areas is the additional combined use of chemical fertilizers, growth-stimulating agents and micronutrients intended for seed and vegetative plant treatment. In 2018–2020 a research was conducted into the effect of the VL 77 growth stimulants and the Orakul Semena, Orakul Multikompleks, and Orakul Sera Activ micronutrient complexes at different growth and development stages during winter wheat cultivation in the volatile weather conditions of the Stavropol Krai arid region. The research establishes the effectiveness of the combined use of the next-generation stimulants during winter wheat cultivation on chestnut soils in the conditions of the Stavropol Krai arid region. The highest yield of the Idilliya winter wheat variety (4.68 t/ha) was achieved by initially dressing the seeds with the VL 77 growth stimulants combined with the Orakul Semena micronutrient complex and treating the seeds with the VL 77 growth stimulants in combination with the Orakul Multikompleks micronutrient complex during the spring growth resumption period. The second treatment of vegetative plants during the flag leaf stage stimulated their growth, but moisture deficit reduced the yields by 2.3%. Still, the yields obtained exceeded the test yields by 4.3%. On average, during the three years of research the growth stimulant and micronutrient complex treatment boosted the yielding capacity in moisture deficit conditions by 4.6–5.1%. The cost effectiveness concurrently increased from 66.0% to 89.0%.

The research was carried out in order to study the effect of the use of biological preparations and micronutrients (separately and in combination with each other) on the growth and development of winter wheat grown according to the sunflower precursor in the zone of unstable moisture. The experience was laid in 2020-2021 on leached chernozem. Two factors were studied in the experiment: drugs and the timing of their use. The classical technology of winter wheat cultivation adopted for the zone was used as a control. The scheme of the experiment included options with the use of biological preparations, micro-fertilizers separately and in combination with each other when etching seeds and during the growing season of winter wheat. The combined use of biological preparations and micronutrients provides an increase in yield by 10.2%, whereas with a separate application the increase was 4.5-5.7%.

Winter wheat is currently the main grain field crop in the European part of Russia. However, to increase the cultivation efficiency, it is necessary to improve cultivation technology. The purpose of the work is to identify new promising varieties and improve the winter bread wheat cultivation technology for the arid conditions of the Povolzhie. In 2015–2019 there was conducted an agroecological testing for 17 winter wheat varieties, which were most widespread and had the prospects for their introduction in the Povolzhie. During 2011–2018 there were studied five cultivation technologies (options) of the winter wheat variety ‘Svetoch’ in the six crop rotation sequences. The study has established that when cultivating winter wheat in the blackearth (chernozem) steppe of the Povolzhie, the varieties ‘Marafon’, ‘Novoershovskaya’, ‘Zhemchuzhina Povolzhiya’, ‘Severodonetskaya yubileynaya’ and ‘Svetoch’ were the most promising varieties. Under favorable moisture conditions, it was most profitable to cultivated the varieties ‘Rostovchanka 7’, ‘Izyuminka’, ‘Marafon’, ‘Bazis’, ‘Severodonetskaya yubileynaya’, ‘Skipetr’. When cultivating winter wheat in ‘black’ fallow, it is more rational to use early fallow, which begins to be cultivated in the spring when the soil is physically matured. The early spring additional fertilizing with ammonium nitrate increases winter wheat productivity on 0.28 t/ha (9.3%). In order to obtain the maximum net income (11324.8 rubles/ha) and profitability (115.0%), it is most expedient to use the biological product ‘Bionex Kemi’ (3 l/ha) on commercial wheat crops.

Abstract During the period 2019 - 2020, a study was conducted on soil type calcic chernozem with Venka 1 common winter wheat variety. The experiment is based on the block method, in four replications with a size of the experimental plot of 10 m2. Sowing was carried out in October with a sowing rate of 500 sprouts/m2 after the predecessor sugar beet. In the appropriate periods, treatments were made in 4 variants: 1) Control - untreated variant, 2) Treatment with biodynamic preparations: 500 + Fladen preparation + preparation 501, 3) Treatment with biological preparations: Heliosulfur + Free N. 4) Combined treatment with the same biodynamic and biological preparations. Preparation 500 was applied in the phase of autumn and spring wheat tillering - 5% solution. Preparation 501 was applied in the phase ear formation - 1.5 g for 30 l of water/da. Fladen preparation is applied in the phase of autumn and spring tillering - 1.5% solution. Heliosulfur was applied in the ear formation phase - flowering at a dose of 50 ml/da, at an appropriate date on the biodynamic calendar. Free N was applied to the soil in the phase of autumn and spring tillering at a dose of 50 ml/da, at an appropriate date on the biodynamic calendar. The analysis of the technological qualities is made according to the respective ISO methodology. The statistical data processing was performed with the STATGRAPH program. The application of biodynamic and biological preparations and their joint use leads to an increase in the yield of wet gluten, as well as an increase in the content of N, P, K and protein in wheat grain. It has been proven that the combined use of biodynamic and biological preparations increases the content of dry matter, organic matter and the content of nitrogen-free extracts in wheat grain. The content of crude proteins has been shown to increase only in the varieties treated with biodynamic and biological preparations.

The purpose of the current study was to determine the amount of moisture consumed by winter wheat to produce yields with the use of biological products and fertilizers. Under the conditions of insufficient and unstable moisture in theRostovregion, the granular mineral fertilizers applied in winter wheat cultivation caused by a moisture deficit do not always give a positive effect. In this case, in our opinion, the use of new biological products and fertilizers in a liquid form for the pre-sowing treatment of seeds and vegetative plants is a very promising direction. Thus, there have been carried out field trials to study the effect of various water-soluble fertilizers and biological products on the moisture consumption and productivity of winter wheat variety “Niva Stavropoliya” sown in fallow lands. The field trials were conducted in 2016–2018 at the AFC (SA) “Rus” of the Salsky district, located in the southern part of theRostovregion. There have been studied such biological products as “Extrasol”, “Rostok”, “Aquamix” and water-soluble fertilizers “Aquarin5”and “Aquarin9”when using optimal doses of fertilizers. The trials have shown that the combined use of biological products and water-soluble fertilizers was the most effective, when used 0.1 kg/t “Aquamix” for seed treatment + 2 kg/ha “Aquarin5”during a period of tillering + 2 kg/ha “Aquarin9”during a period of head formation together with the use of mineral fertilizers. As a result, productivity increase was 36% compared with that of the control.

Abstract. The article presents the results of research of the South-Ukrainian branch of UkrNDIPVT L. Pogoriloho on the adaptation of winter wheat cultivation technologies in grain and steam crop rotations to increase the aridity of the climate by optimizing the density of standing plants, methods and depth of basic tillage. The purpose of research is to adjust the seeding rate by changing the width of the rows when growing winter wheat, as an agro-technological measure of accumulation and rational use of soil moisture (agro-technological direction of adaptation to climate change). Determining the influence of sowing rate, with different methods of tillage, on the productivity and economic efficiency of growing winter wheat in crop rotations on non-irrigated lands of southern Ukraine. Methods and Materials: field, quantitative-weight, visual and laboratory methods. Mathematical and statistical methods were used to systematize and generalize the obtained results. Research results. It has been experimentally established that the replacement of plowing to a depth of 28-30 cm for winter wheat crops with shallow (10-12 cm) disc tillage and reduction of the sowing rate of winter wheat variety «Kherson-99» to 2.25 million pieces similar seeds per hectare, by increasing the width between rows, provided an increase in grain yield by 16.7 % in 2020 and 7.7% in 2021. The profit per 1 hectare with this technology amounted to UAH 13280,5 in 2020 and UAH 28484,9 in 2021, which is 18.4 % and 9.3 % more than similar indicators in deep plowing and 31.3 % and 8.9 % more than the classic sowing rate (4.5 million units/ha). Conclusions. The efficiency of replacing deep plowing with shallow disc loosening and reducing the sowing rate to 2.25 million units/ha in the cultivation of winter wheat Kherson-99 in grain and steam crop rotation of the South of Ukraine was confirmed. A regularity in the size of the effect of reducing the seeding rate under drier conditions of the growing season was revealed.

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%.

At present winter wheat is the leading grain crop in the Volga region and Russia. However, it’s necessary to improve its cultivation technologies to increase its efficiency. The purpose of the work is to identify the optimum sowing methods and rates of winter soft wheat with the application of disinfectant ‘Stsenik Kombi’ in the climatic conditions of the Middle Zavolzhie. In 2015–2018 there was estimated the influence of two sowing methods (row and wide-row) and five sowing rates of the winter wheat variety ‘Svetoch’ when applying disinfectant ‘Stsenik Kombi’ in comparison with the control variety. It has been established that the highest net income (12251.5–12498.3 rubles/ha) and level of profitability (107.7–121.5%) were obtained on options with the sowing rate of 2.0–4.0 million/ha. The highest breeding rate was found in the usual ordinary sowing rate of 1 million/ha to 100 (in 2016), which is in 2–4 times higher than when sown with the rate of 2.0–5.0 million/ha. The obtained regularity indicates the prospects of this sowing rate when cultivating seeds of high reproductions for seed production purposes, both in ordinary row sowing (the width of the spacing is 15 cm), and in wide-row sowing (30 cm). When sowing 2.0 million/ha or more, there was established a prevalence of ordinary row sowing over wide-row sowing on 0.4 t/ha (or 16.9%). The application of disinfectant ‘Stsenik Kombi’ is recommended in winter wheat cultivation.

Set Up

The influence of different fertilizer doses on the yield and quality of winter wheat was studied on meadow soil in the crop-year 2016-2017 in Hódmezővásárhely. The experiment was set up on the area of the SZTE Tangazdaság Ltd, in three replications. The forecrop was sunflower. Six fertilizer setups were applied besides the control: N80PK30, N100PK30, N130PK30, N150PK30, N170PK0, and N170PK50 kg/ha active ingredients. The year 2016-2017 was unfavourable for winter wheat production. The amount of precipitation in the vegetative period of winter wheat was lower than the average. The obtained data were processed by single factor ANOVA. In the control treatment, the yield was 4.20 t/ha. The maximum yield of 5.60 t/ha was reached with N130PK30 kg/ha fertilizer treatment. The yield difference between the two treatments was statistically justified. The nutrient doses higher than N130PK30 did not increase the yield of wheat. A crude protein content of 17.60% was measured in the N0PK0 treatment. The highest content of crude protein (18.70%) was in the N100PK30 and N130PK30 treatments. The Zeleny number was 70.40 ml in the control treatment. In the N130PK30 treatment, it reached the maximum value of 76.0 ml. In our experiment, the N130PK30 kg/ha fertilizer dose was the most favourable concerning the yield and quality parameters of the examined winter wheat variety.
