The article presents the results of the study of the influence of mineral fertilizers, green manure,seed treatment with biopreparations and spraying of crops with Biocomplex-BTU on the parameters ofproductivity and affection of two varieties of wheat by the mildew of plants. It has been established thatpre-seeding bacterization contributes to the increase of yield by 0.09-0.34 t/ha, depending on thebiopreparation and fertilization. Under the action of mineral fertilizers alone or in combination withgreen manure, the yield increased by 1.74-2.21 t/ha, compared with the variant without fertilizers andwithout inoculation. The treatment of winter wheat crops by Biocomplex-BTU promotes yield increase by0.19-0.34 t/ha, depending on the fertilization and inoculation of seeds. Under inoculation of seeds andtreatment of crops with biopreparation, the number of productive stems and grains in the spike increases,while the weight of 1000 grains is predominantly reduced.Under use of fertilizers, specified parameters increase significantly. The most effective is the use ofbiopreparations without fertilizers.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

Treatment of the triticale phytomass with the complex biological preparation KBP-5M before incorporation into the soil contributed to the activation of microbiological processes in the 0-30 cm layer. In the variants when the plant was in the phenological stage of spike emergence, we noted an increase in the content of N-NO3 by 0.19-0.46 mg per 100 g of soil; Р2О5 – up to 2.97; K2О – up to mg/100 g. The reason for that was the maximum accumulation of organic matter in the phytomass of triticale at the aforementioned stage of development (8.25-8.52 t/ha). The use of KBP-5M had a positive effect on the development of winter wheat when green manure was the preceding crop. There is a tendency to increase the density of the stalk by 13.3 %, including productive stems – by 3.9 % and the number of grains from 10 plants – by 1.7 % compared to the use of triticale plants as an organic fertilizer without the treatment with biological preparation. Despite the trend of increasing yields from 4.32 to 4.43 t/ha, no reliable yield increase was obtained. When applying KBP-5M on triticale plant residues, there was an increase in protein content by 0.3 % and gluten – by 1.1 % compared to variants without the biological preparation. According to the indicators of 1000-grain weight and hectolitre weight, there were no significant differences between the studied variants. The use of KBP-5M has been justified from an economic point of view since 277 to 1535 rubles per ha of contingent net income was obtained and the payback ratio for the use of the biological product was 1.05–5.79.

Дослідження, проведені протягом 2005–2017 рр., свідчать про ефективність використання гуматів у технології вирощування пшениці озимої, зокрема препаратів «1R Seed Treatment» та стимулятора росту «4R Foliar Concentrate». Поєднання передпосівної обробки насіння та листової аплікації посівів дає змогу збільшити врожайність пшениці озимої на 11,8–27 %, а проведення лише позакореневого підживлення сприяє формуванню приросту врожаю в межах 7,4–13,8 %. Диференційоване застосування стимулятора росту «4R Foliar Concentrate» у різні фази розвитку рослин пшениці озимої має кращий господарський і економічний ефект, порівняно з одноразовим. У варіантах досліду, де разом із передпосівною обробкою насіння використовувалося і позакореневе внесення «4R Foliar Concentrate», прибавка врожайності становила 0,76 т/га, або 20,9 %. Застосування «4R Foliar Concentrate» 2 кг/га у фазу виходу в трубку сприяло подальшому підвищенню врожайності, розмір приросту якої становив 23,1 %. Найкращий ефект забезпечила передпосівна обробка насіння гуматом, яка поєднувалася з позакореневим підживленням посівів, а листова аплікація проводилася в два прийоми по 1 кг/га «4R Foliar Concentrate». Прибавка врожайності становила 0,98 т/га, або 27 %. In the presented studies, pre-planting seed treatment increased the yield of grain by 0.43 t/ha, which is almost 12 %. Taking into account the high grazing rate for seed of cereal crops with a continuous sowing method, the cost of using the full recommended standard for the seed treatment would be about 25 % of the total production costs of the cultivation technology. So it is a significant additional production costs, which, in the current financial situation, the vast majority of agribusinesses are not able to invest in crop growing technology. In this regard, we have chosen the minimum rate of application of the drug 1.0 l/ton of seeds. Although calculations show that even the maximum rate of use of «1R Seed Treatment» for reaching an increase in winter wheat yield of 0.5 t/ha will be economically feasible. In the variants of the experiment, in which the seeds of the pre-planting treatment were used for root crop fertilization with «4R Foliar Concentrate», the yield increase of winter wheat grain was 0.76 t/ha or almost 21 % compared with the control. Application of 2 kg/ha «4R Foliar Concentrate» to the phase of the tube led to a further increase in yield, which was 23.1 %. The most effective in the described experiment was the variant, where the pre-sowing treatment of seeds with humate was combined with fecal application, but the leaf application was carried out in two receptions of 1 kg/ha «4R Foliar Concentrate». The yield increase was 27 %, which confirms the recommendations of the manufacturer of these drugs and the leading European companies regarding the use of their own products for a multiple entry. In the experiment block, which used only leaf application, the effectiveness of the drug «4R Foliar Concentrate» was significant. Only one treatment of the crop with the drug in the phase of release into the tube contributed to an increase in yield of 0.27 t/ha or 7.4 %. An increase in the rate of use of the drug up to 2 kg/ha has a stronger effect and increased the yield of winter wheat grain, compared with the control, by 0.38 t/ha or 10.5 %. A fractional introduction of the same norm into different phases of the development of culture is accompanied by an increase in yields by 0.50 t/ha, compared with the option without fertilization and increases additional profits, compared with the single use of the entire drug norm. Thus, differentiated use of drugs was more effective than single use. Studies have shown the effectiveness of the use of humates in winter wheat cultivation technology, in particular, «1R Seed Treatment» and growth stimulator «4R Foliar Concentrate». The combination of pre-sowing seed treatment and leaf application of crops enables to increase the yield of winter wheat by 11.8–27 %, and the use of sheet-laying applications only provides grain growth within the range of 7.4–13.8 %. The differentiated application of growth promoter «4R Foliar Concentrate» has a better economic and economic effect than a one-time use.

Zinc Application

To improve the technology of winter wheat cultivation it becomes more relevant to discuss the issue of enhancing crop microelement nutrition, which is very important when mineral fertilizers are applied at a higher rate than the one accepted in the zone. Chornozem (black) soils in general, and southern ones in particular, have a neutral or slight alkaline response, i.e. most of the microelements are slow movable and in fact are not available for the plants. The efficiency of the microelement application uppermost affected by the form they are in. Recent experiments prove that the most efficient form of microelement transportation to the plants is complex compounds of metals with organic ligands – chelates. The most common chelators are organic acids with carboxyl groups: ethylendiamintetraacetic (EDTA), diethylentryaminpentaacetic (DTPA), dihydroxybutylendiamintetraacetic (DBTA), ethylendiamindisuccinic (EDDA); phosphonic acids – oxyethylendendiphosphonic (OEDF) and nitryltrymethylenphosphonic (NTF). The research aims to study the effect of forms and ways of zinc application on the yield formation and grain quality of soft winter wheat on the southern chornozems (black soils). The experiments were carried out on southern chornozems, low-humus heavy loamy well-cultivated. The size of a sown plot is 120 m2, that of a record one is 50 m2, replication is fourfold. Fertilizers were applied in a form of ammonium nitrate, granulated superphosphate and potassium salt, and also superphosphate with zinc complexonate (0.75 %). Vegetative winter wheat fields were treated with the solutions of zinc salts with help of a manual sprayer. An experiment scheme was given when the results were presented. Black fallow was the predecessor of winter wheat, cv. Knopa. The efficiency of microelement was studied when it was applied in the form of zinc sulfate, chelate form, where oxyethylendendiphosphonic (OEDF) oxyethylendendiphosphonic (OEDF), superphosphate with zinc chelate on OEDF basis were used as ligand (0.75 %) Monitoring and analyzing were done according to the conventional methods in compliance with a standard technique. Statistical processing of the received results was done using a package of applied software Excel and Statistika, the methods of dispersive, correlative and regressive analyses. When N90P60K40, which contained superphosphate modified with zinc complexonate based on OEDF, was applied, the yield increase was 20.2 % as compared with the variant without fertilizers, including 6.4 % – due to zinc. It is advisable to apply zinc in the form of its complexonate with OEDF, the yield increase is 0.15 cwt/ha, as compared with zinc sulfate, and a share of the effect of this factor is 14.0 %. The application of zinc complexonate under pre-sowing cultivation at a rate of 2.0 kg/ha had no benefit over one-time treatment of the plants at the phase of tillering at a rate 250 g/ha, but doing this treatment at a phase of shooting resulted in a serious yield increase (0.20 t/ha at SSD 0.95 = 0.18). Foliar application with the solution of zinc complexonate (250 g/ha) increases the grain yield of winter wheat with the highest effect from a two-time treatment at tillering and shooting phases; the increase ranges from 0.20 to 0.54 t/ha. The efficiency of Zn application by 75.7-96.0% in arid conditions of the south of Ukraine is defined by hydrothermal conditions of spring vegetation, and a microelement helps winter wheat plants develop resistance to a temperature stress. A grain zinc concentration in the experimental variants ranged from 18.4 to 22.1 mg/kg (in the control it was 14.5 mg/kg).

The purpose of research is to identify the influence of the fertilizers aftereffect and ameliorator for yield formation and quality of winter wheat grain Bezostaya 1after predecessor (potatoes) in the unirrigated soils of the Askeran region of NKR in 2011-2014. It should be noted that the winter wheat in the region is an advanced crop, but due to lack of irrigation water and the lack of rainfall is often collected by low yields. Research has established that the aftereffect of fertilizers and meliorants noticeable effect for growth, grain quality and yield formation, the amount of which depends from the application of the system of fertilizer. It is proved that more weak effect preserved when under a precursor have been made only mineral fertilizers (N90P90K90), where as potassium fertilizer was used potash (N90P90K90 option), and when on the same background was used gypsum or bentonite. If in the system N90P90K90 fertilizer (KCl) instead of KCl was used treated dacitic tuff (OTD) or on the same MM backdrop bio-fertilizer, as well as an option manure 30 t/ha + N90P90K90 (KCl), the consequence was significant. In these embodiments, the yield increase compared to control 1 (no fertilizer) was 30.2-57.2%, as compared to the control 2 (N90P90K90 option (KCl) – 10.8-30.6%. In these embodiments, the content of NPK was high in the grain: 1.90-2.15% N; 0.93-0.97% P2O5 and 0.77-0.85% K2O, whereas in the control 1 1.78% nitrogen, phosphorus – 0.69%, 0.53% potassium, and in control 2, accordingly – 1.80%, 0.81%, 0.65%.

The problem to provide the livestock industry of the North-West of Russia with forage grain has sharply escalated since 2010. Its successful solution is connected with the level and validity of the use of mineral and organic fertilizers. The purpose of the study, started by the Menkovsky Branch of the AFI in 2012, was to find effective options for the use of new organic-mineral fertilizer (OMF) which provides maximum agronomic effect and can produce grain of high quality. The methodological basis was the micro trials in polyethylene vessels without bottoms of 1 × 1 × 0.4 m in size with an artificially formed upper part of the profile of degraded sandy sod-podzolic soil. The soil was of 4.75 рНKCl, 3.46 mmol (eq) of Ng per100g, 3.20 mmol (eq) of Sch per100g, 1.83% of humus, 217 mg / kg of mobile compounds of phosphorus and 92 mg / kg of potassium. In the course of research, there was high agronomic efficiency of its use for winter wheat and satisfactory agronomic efficiency of its use for barley. When the winter wheat variety ‘Moskovskaya 56’ was fertilized with 5 t/ha of organic-mineral fertilizer containing 2.46% of Ng, 4.51% of P₂O₅ and 3.36% of K₂O, grain yield increased in 2.6 times. Fertilized with N75P50K50 the productivity improved in 3.8 times with a payback of 1 kg of NPK 7.4 and 5.6 grain units, respectively. It has been established that the combination of OMF with mineral fertilizers is accompanied by a significant yield increase with a decrease in its relative contribution from 153% to 59% and from 143% to 105% and a payback of 1 kg of NPK from 3.8 to 2.6 and from 6.9 to 4.7 of barley grain units and winter wheat grain units, respectively. The best indicators of the agronomic efficiency of OMF, both when applied in pure form and when fertilized with N75P50K50, corresponded to a dose of 4 t / ha. It has been found that the addition of 10 kg of potassium (К₂О) per 1 ton to OMF provided yield increase on 15% and the payback period of 1 kg NPK increased from 6.4 to 8.4 grain units. Qualitative indicators of wheat and barley grain fertilized with OMF improved due to the rise of raw protein percentage on 8–27% and a number of ash elements, such as CaO (from 0.07 to 0.11 mg/kg), MgO (from 0.16 to 0.21 mg/kg), Zn (from 21.5 to 23.6 mg/kg).

Field experiments were conducted in 2017-2020 on the southern black soil in the conditions of the Lower Don. The Doneko winter wheat variety was sown. The predecessor of wheat is corn for grain. Mineral fertilizers were represented by ammonium nitrate (34.4%), nitroammophosk (16-16-16) and carbamide (46%), which acted as a background option in the scheme of the ex-periment. Organomineral fertilizers were preceded by the following agrochemicals: Ruther, Leyli 2000, Alga 1000/Turbo, Siamino Pro, Gumiful Pro, Soft Garden (Master Green Mix) and Double Vine (Monocaliphosphate). In the experiment, options for the joint use of non-root application and pre-sowing seed treatment with organomineral fertilizers were also studied. It was found that the use of organomineral fertilizers Ruther (0.5 or 0.25 l/ton) and Leyli (0.25 l/ton) for seed treatment before sowing, the use of Soft Guard (0.2 l/ha) and Humiful Pro (0.2 l/ha) in spring tillering and in the flag leaf phase against the background of a starter treatment mineral fertilizer in the form of azofoska at a dose of N32P32K32, fertilizing on frozen-thawed soil with ammonium nitrate at a dose of N40 and non-root topdressing with carbamide in the phase, earing at a dose of N20 increased the increase in grain yield on average for 3 years compared to the control variant (farm fertilizer system) by 0.73 t/ha or by 23.0%. The greatest increase in yield from the Router root-forming agent used for seed treatment was 0.36 t/ha or 11.3%. Keywords: WINTER WHEAT, MINERAL FERTILIZERS, ORGANOMINERAL FERTILIZERS, YIELD

Objective. Develop a fertilization system for spring wheat based on the use of effective compositions of nitrogen-fixing and phosphorus-mobilizing bacteria, which will help to reduce the spreadof disease and increase the productivity of agrocenoses. Methods. Field, measuring- and weightbased, calculation, mathematical and statistical. Results. The influence of mineral fertilizers, aftereffects of green manure, treatment of seeds with biopreparations and spraying of crops with Biocomplex-BTU on the parameters of productivity and exposure of spring wheat to powdery mildewhas been shown. It was found that pre-sowing bacterization of seeds increases yields by 3.3–12.4 %, depending on the biopreparations and fertilization background. Under the action of mineral fertilizers both separately and against the background of the after-effect of green manure, theyield increased by 31.7–41.2 %, compared with the variant without fertilizers and without inoculation. Treatment of spring wheat leaf with Biocomplex-BTU increased yield by 3.6–7.2 %, dependingon fertilizer and pre-sowing bacterization of seeds. Inoculation of seeds and treatment of crops withbiopreparations results in increase in the number and length of productive stems and grains inthe ear, although the use of fertilizers increases these parameters more significantly. Conclusion. Treatment of wheat seeds with bacterial preparations has a higher percentage efficiency in areas without fertilizers compared with fertilized ones, as well as in less favourable years for thegrowth of spring cereals, compared with more favourable. Seed inoculation with Polimiksobakterynin combination with the treatment of crops with Biocomplex-BTU, which, depending on the fertilizer, increases the crop yield by 0.54 to 0.73 t/ha, is the most effective. Crop treatment with Biocomplex-BTU significantly reduces exposure to powdery mildew.

The article presents the results of a field experiment on the different fertilizers effect (green manure, manure, straw, mineral fertilizers) on the soil agrochemical properties under the Terek-Sulak plain of the Republic of Dagestan irrigation conditions. At the experimental Kirov station, of the Khasavyurt District on a total area of 1505 m2 in 2015-2019 were studied the content of the main nutrients in cattle manure, the phytomass of green manure crops and the dynamics of fertilizers for nutrients in the arable layer. Green manure crops (seed peas, spring rape, and amaranth) were sown during the stubble period after harvesting winter wheat. The plowing under of green manures herbage was carried out in the initial phase of budding, winter wheat straw – 2 t / ha, cattle manure – 30 t / ha, mineral fertilizers – N150P75K75. Then water-charging irrigation was used 1000-1200 m3 / ha. Soil studies revealed that in the areas of the experiment where the sowing peas grew, nitrate nitrogen for the entire growing season next year contained 37.8-54.1 mg / kg, mobile phosphorus under crops of spring grain crops – 33.0-34.84 mg / kg of soil was noted in spring and to autumn its amount in the topsoil was gradually decreased (23.5-24.9 mg / kg). The exchangeable potassium amount in the meadow chestnut soil (control without fertilizers) was varied slightly. The manure application by its positive effect on the specified soil regime approaches to the spring rape and amaranth green mass plowing under. The most favorable soil regime under irrigated conditions were formed during plowing of the sowing peas green mass.
