The current study was carried out in the southern part of the Rostov region at the FSBSI “Agricultural Research Center “Donskoy” in 2018–2020. The purpose of the study was to investigate the combined effect of mineral fertilizers and treatments with the growth retardant ‘Moddus’ on productivity of the barley variety ‘Marusya’. In the course of the study, there was identified high responsiveness of the facultative barley variety ‘Marusya’ to the use of mineral fertilizers. Without fertilization, the productivity was 3.46–3.59 t/ha, and 0.87–1.57 t/ha when using the fertilizers. The maximum productivity and protein percentage were established in the variants with the introduction of N79P82K57 according to the active ingredient, with 5.81 t/ha and 0.55 t/ha, respectively. The treatment of plants with the growth retardant ‘Moddus’ contributed to productivity increase on 0.13–0.22 t/ha on average over the years of study. Under the effect of the growth retardant ‘Moddus’, the number of productive heads increased on 5–19 pieces/m2 , there was also a tendency to an increase in the number of grains per head and grain weight per head. The growth retardant ‘Moddus’ contributed to a decrease in plant height on 3.6–5.6 cm, at the same time there was a tendency to increase length of head on 0.2–0.5 cm in comparison with the control variant. Mineral fertilizers effectively increased nature weight of the facultative barley variety ‘Marusya’. Without fertilization, nature weight of grain was 579 g/l and 584 g/l, and when using fertilizers, it increased on 16–27 g/l or 2.7–4.6%. Productivity increase in the variant when treating with the growth retardant ‘Moddus’ resulted in an increase of the indicator of conditional net income over the control variant on 745–1884 rubles/ha.

The field trials were conducted in 2017–2019 in the laboratory for cultivation technologies of row crops in the FSBSI “Agricultural Research Center “Donskoy”. The experimental plots were located in the southern soil-climatic zone of the Rostov region characterized with insufficient and unstable moisture. The soil of the experimental plots was heavy-loamy ordinary blackearth (chernozem) on forestry loams with 3.2% of humus, fertilized with 18.5 – 20.0 mg/kg of P2O5 and 342 – 360 mg/kg of K2O. The current paper has presented the study results of the effect of herbicides on middle ripening maize hybrid “Zernogradsky 354 MV”, included in the State List of RF in 2010. The used herbicides had a positive effect on reducing the contamination of maize sowings with monocotyledonous and dicotyledonous weeds (90% decrease), which contributed to an improvement of grain crop productivity. In the phase of full ripeness, the number of weeds in the experimental variants was 2.7–3.1 times less than in the control variant. The productivity increase in the control variant was 0.55–0.83 t/ha. The largest net income (22 545 rub/ha) was obtained due to the use of the herbicide “Elumis”. The high cost of the preparations negatively affected the cost of production, which exceeded the control variant on 436–519 rubles per ton. The profitability of the applied herbicides was lower than the control variant on 30 and 39%. The grain productivity increase obtained in the trials has paid for the costs of herbicides’ use; the payback amount was 1.15–1.57 rubles.

The current paper has presented the results of three years’ study (2012–2014) of the application of various terms and methods of nitrogen additional fertilizing for the winter bread wheat variety “Stanichnaya”. There has been studied efficiency of various terms and methods of nitrogen additional fertilizing with various forecrops. There has been identified an effect of these additional fertilizing on winter bread wheat productivity according to the forecrops. In the control variant, the productivity of the variety according to the forecrop depended greatly on the forecrops: 5.52 t/ha (weedfree fallow), 5.26 t/ha (peas), 4.29 t/ha (maize for grains) and 3.57 t/ha (winter wheat). There has been identified large productivity in the autumn ammonium nitrate fertilizing by the scattering method (in all variants of the forecrops), the productivity raised on 0.38–0.73 t/ha. The study has shown that the economic effect of the ammonium nitrate fertilizing in the autumn was also at maximum profitability, 76–154%, and the conditional net income was 10 675–22 955 rubles/ha. The efficiency of ammonium nitrate fertilizing by the scattering method in the spring on thawed/frozen soil was lower, the productivity increase ranged from 0.21 t/ha sown after peas to 0.65 t/ha sown after maize. Root additional fertilizing with a seeder gave a positive effect only when the variety was sown after for winter wheat and maize, in that case the productivity increase was 0.52 t/ha and 0.46 t/ha, respectively. The conditional net income in these variants exceeded the control variant on 1574–2123 rubles/ha. Carbamide (urea) additional fertilizing was only effective for the variety sown after maize, where the productivity increase was 0.40 t/ha, but profitability (100%) and conditional net income (16 593 rubles/ha) were lower than with ammonium nitrate fertilizing by the scattering method in the spring (112% and 18 080 rubles/ha respectively).

An increase in spring barley acreage requires a detailed study of the interaction of agronomic and climatic factors, as well as the selection of a modern set of new varieties. The use of mineral fertilizers is one of the most important methods to improve the productivity of grain crops and maintain a deficit-free balance of mineral nutrients in arable soils. The current study of the effective use of various doses of mineral fertilizers (NPK) on the new spring barley variety ‘Znatny’ was carried out on dark-gray forest heavy loamy soil in 2018–2020 by the Institute of Seed production and Agrotechnologies, a branch of the Federal Budgetary Scientific Institution “Federal Research Agro-Engineering Center VIM”. There has been established that the date of the phenological phases and the length of interphase periods did not depend on fertilizer rates, but had a close correlation with weather conditions (r = +0.68). The analysis of the obtained data has shown that an increase in the rates of applied fertilizers increases the aboveground biomass, which, in turn, negatively affects productivity of the barley variety ‘Znatny’ (r = -0.77). The analysis of the yield structure and rates of fertilizers NPK has shown that in the trial, the spring barley productivity was influenced by 1000-grain weight (r = +0.60). There was found a high inverse correlation between productivity and length of head (r = -0.85). When length of head ranged from 7.5 to 8.4 cm, grain weight per head remained practically at the same level in all variants (1.1–1.2). This indicated that at a rate of N90P90K90 and N120P120K120, the variety ‘Znatny’ formed a not very dense head. Protein percentage at these rates also greatly reduced. According to the obtained data, an increase in the doses of applied fertilizers (N90Р90К90–N120Р120К120) resulted in the intensified development of most leaf diseases and a decrease in lodging resistance. Thus, the optimal dose of application of azophoska fertilizer on dark-gray forest soil is the norm N45P45K45, since on this option there was obtained maximum productivity and net income. the increase in the recom[1]mended norms of mineral fertilizers, sharply reduces profitability of crop cultivation.

The results of the research were obtained in 2019-2020 on sod-podzolic middle-loam soil in the conditions of EuroNorth-East of the Russian Federation. There were studied 18 variants of increasing doses of mineral fertilizers in the range from 30 to 150 kg of active ingredient per hectare. Under the conditions of 2019 growing season, nitrogen fertilizers influenced the value of yield of Novichok barley variety to a greater extent (Y = 0.67 - 0. 11x2 + 1.33x, R2 = 0.92), in 2020 - phosphorus fertilizers (Y = 1.48 - 0.02x2 + 0.48x, R2 = 0.99). On average, over 2 years of research, the yield in the control variant without the use of fertilizers was 0.87 t/ha. Yield increase of barley grains because of enlarged fertilizer doses ranged from 1.38 to 3.90 t/ha. The payback of 1 kg of active ingredient of fertilizers with increase of barley yield decreased due to enlarged doses: from 15.3 (N30P30K30) to 8.3 kg (N150P150K150). On average for two years of the research the increasing doses and ratios of mineral fertilizers had no significant effect on technological properties of spring barley seeds. The content of crude protein in grain grew with increase in fertilizer doses (r = 0.55). To obtain grain of the 2nd class of quality it is necessary to apply not less than 90 kg of active ingredient/hectare of ammonium nitrate. According to the content of crude cellulose, the 1st class of grain quality has been obtained, and this indicator did not depend on the application of fertilizers. High profitability of cultivation of the Novichok spring barley variety (from 54.2 to 59.1 %) has been recorded by application of mineral fertilizers in doses N60P60N120, N60P60K60 and N120P120K120.

The current paper has presented the study results of the effect of different dosages of the herbicide ‘Ballerina SE’ on the weediness of sorghum sowing, as well as the economic efficiency of the application. The purpose of the study was to estimate the efficiency of the use of the herbicide ‘Ballerina’ on grain sorghum and its effect on the weediness of the sowing and the amount of productivity. The field trials were carried out in 2017–2019 in the laboratory for cultivation technology of row crops of the FSBSI Agricultural Research Center “Donskoy” (Zernograd). The experimental plot is located in the southern agricultural zone of the Rostov region (with insufficient and unstable moisture). The soil of the experimental plot was ordinary heavy loamy blackearth (chernozem) on forestry loams, with 3.2% of humus, 18.5–20.0 mg of P2O5 and 342–360 mg of K2O per kg of soil. The hydrothermal coefficient during the years of study ranged from 0.32 to 0.89, which characterized the insufficient moisture supply of the growing season. There was presented the information on the varietal composition of grain sorghum in the southern zone of the Rostov region. The applied dosages of the herbicide had a significant effect on the reduction of the weediness of grain sorghum after their application (the decrease ranged from 78.3 to 96.7%). The greatest decrease in weediness was noted for dicotyledonous weeds. When using 0.5–l of the herbicide ‘Ballerina SE’ per ha, there was obtained the highest conditional net income of 22,230 rubles/ha, with the lowest production cost of 4,329 rubles/ha and the highest profitability level of 163%.

The current study was carried out on ordinary blackearth (chernozem) in the southern part of the Rostov region in the FSBSI “ARC “Donskoy” (2017–2020 agricultural years). The purpose of the work was to identify the effect of autumn and spring sowing periods on grain productivity and quality of the facultative barley variety ‘Marusya’ according to various forecrops. There has been considered the dynamics of the productivity of the variety ‘Marusya’ depending on the sowing time when sown after maize for grain and sunflower. There has been established high adaptability of the variety ‘Marusya’ after nonfallow forecrops. It has formed a high productivity when sown in autumn at various times. There has been found out a positive reaction of the variety to sowing on September 10, 20 and 30, where the maximum productivity when sown after maize for grain was 6.76–6.91 t/ha. When sowing at later time, there was a slight decrease in productivity. When sown in spring, the highest protein percentage in grain was 11.0 and 11.6%. However, due to the highest productivity, the maximum protein yield was when sowing in autumn, up to 0.71 t/ha. The calculation of the economic efficiency of grain production showed that the highest profitability (214.1 and 214.4%) was obtained when the variety ‘Marusya’ was sown on September 10 and 20 after maize for grain. On average, over the years of study, the maximum conditional net income according to the forecrop, depending on the sowing time, was from 59658 to 84261 rubles/ha when sown in winter and from 48881 to 59170 rubles/ha in spring. The minimum profitability 62.1–75.2% was identified when sown in spring in 10 days after the soil was physically mature.

Annual and perennial grasses are important not only as a source of green fodder, hay, silage, grass meal and haylage in feed production, but also as good forecrops, due to the ability to accumulate biological nitrogen in the soil (since it decreases the cost of mineral fertilizers), to disinfect the soil from micro zoo pests, to improve the physical condition of the soil (since it decreases soil density). Perennial grasses are also an important component of biologized crop rotations, since the amount of crop residues remaining in the soil after harvesting is several times greater than after winter crops. The field trials were conducted in 2009–2016 by the staff of the laboratory of row crop cultivation technology of the FSBSI “Agricultural Research Center “Donskoy”. The experimental plot is located in the southern soil-climatic zone of the Rostov region (with insufficient and unstable moisture). The soil of the experimental plot is ordinary heavy loamy chernozem on loesslike loams, with 3.2% humus, neutral pH, and a high content of movable phosphorus and exchange potassium according to Machigin. The current paper has presented a bioenergetic estimation of grain (4-crop rotation sequence with annual grasses included) and biologized (8-crop rotation sequence with 25% perennial grasses) crop rotations. It has been established that nutrients’ amount per 1 ha of crop rotation area of biologized crop rotation is higher than in grain crop rotation on 22% of dry matter, on 40% of raw protein and on 39% of metabolic energy. Energy consumption per 1 kg of raw protein is lower on 27%.

Field experiments to study the effectiveness of the use of mineral fertilizers and biological products with strains of associative nitrogen fixers were conducted in 2016-2018 on dark brown soil in LLC "Zarya" of the Oblivsky district, which is located in the north-eastern zone of the Rostov region. The objects of research were: the variety of safflower Zavolzhsky 1, bacterial preparations Mizorin, Flavobacterin, KL-10, made at the All-Russian Institute of Agricul-tural Microbiology in St. Petersburg. They were mixed immediately before sowing with seeds at a rate of 300 g/ha. Mineral fertilizers were represented by ammonium nitrate (34.4%), ammophos (12:52) and potassium chloride (65%). Safflower was cultivated according to traditional technology. The sowing of safflower was carried out with the SZ-3,6 seeder. The predecessor of safflower is winter wheat. The application of mineral fertilizers was carried out simulta-neously with sowing, as well as manually spreading for pre-sowing cultivation. The yield of safflower seeds in the control variant (without the use of agro-chemicals) was the highest in 2017, which was favorable for moisture-1.11 t / ha, and almost the same in 2016 and 2018 – 0.92-0.94 t/ha, respectively. Av-erage for 2018-2020 the yield of safflower seeds in the control variant was 0.99 t / ha. The highest yield of oilseeds was obtained on the variant with a dose of mineral fertilizers N48P52 1. 22 t / ha, but on the variant with the use of the biological product Flavobacterin, the yield was only 0.05 t / ha less. The oil content in safflower seeds on average for 3 years of research on all variants of the experiment differed slightly. Its content varied from 35.7–36.3% and did not depend on the studied agrochemical techniques. The most optimal indica-tors of economic efficiency in the experiment were obtained from the use of a strain of the associative biological product Flavobacterin on a natural back-ground of fertility. The level of profitability is higher than in the control ver-sion by 28%, with a reduction in the cost of 1.42 rubles/kg. Keywords: SAFFLOWER, MINERAL FERTILIZERS, BACTERIAL PREP-ARATIONS, YIELD

The use of biological stimulants promotes plant metabolism, which improves the utilization of mineral fertilizers and plant defense mechanisms against the effect of unfavorable factors. The paper discusses the results of winter wheat seed treatment with ‘Agrimitin’ and a fungicide disinfectant ‘Vintsit Forte’. It has been determined that seed treatment with the preparations promoted the increase of winter wheat productivity. In 2017–2018 after seed treatment with ‘Agrimitin’, the average productivity increase was 0.18 t/ha for the winter soft wheat variety ‘Lydia’ and 0.25 t/ ha for the winter durum wheat variety ‘Lazurit’ compared with the productivity of the control variety. The combined use of preparations promoted the productivity increase on 0.37 t / ha for the winter soft wheat and on 0.44 t /ha for the winter durum wheat. The structural analysis of productivity showed that the use of preparations increased the number of productive stems to 580–648 pcs/ m2 in comparison with 564–621 pcs/m2 of the control variety. A number of kernels per ear and mass of kernels per ear of winter soft wheat after seed treatment had no significant increase. Winter durum wheat showed better effect of seed treatment: ‘number of kernels per ear’ increased from 30.6 pcs. to 32.8 pcs., and ‘mass of kernels per ear’ raised from 1.38 g to 1.55 g. The maximum profitability of winter soft and durum wheat production was identified in the variant with a combined use of the preparations ‘Agrimitin’ + ‘Protravitel’ (184.2% and 208.6% respectively). At the same time, the net income rate of winter soft wheat increased on 3,136 rubles/ha and that of winter durum wheat increased on 4,624 rubles/ha, compared to the the net income rate of the control variety (58145 rubles/ ha and 64796 rubles/ha, respectively).
