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%.

The paper discusses the issues of fertilizers effect on germination, plant productivity and overwintering of Kazanskaya 560 variety winter wheat. The results showed that pre-sowing seed treatment by Humate fertilizer “Bioplant Floro” calculated 0.5 liters per ton increases the seed germination to 4-5%, the accumulation of sugars in the tillering nodes of winter wheat to 10-11%, and the safety of overwintering plants to cleaning to 5-10%. The calculated fertilizer norms allow to get close to planned levels of crop during favorable weather conditions. Treating the seeds by “Bioplant Flora”, the yield exceeded the target level (4.1 tons per hectare instead of planned 4 tons per hectare of grain). An application NPK and ammonium nitrate as an ordinal fertilizer at planting provides almost the same level of productivity of the main fertilizers, calculated to produce 3 tons per hectare. It is undesirable to use ammonium nitrate fertilizer on winter wheat as ordinal, especially after steam cleaner with a high nitrogen content. This can reduce its winter hardiness quality. Good results are obtained by using nitrate in the doze 1 centner per hectare in bulk

The purpose of the study was to scientifically substantiate the effectiveness of polishans and Macroshans as elements of the technology of winter wheat cultivation in the conditions of the Central forest-steppe, their effect on productivity and product quality. Experiments, observations, records, and analyses were carried out using the field experience methodology [6]. Statistical processing of the results was performed using methods of analysis of variance. Treatment of seeds with Polishans at a dose of 0.2 l / t promoted the growth and development of winter wheat plants on all backgrounds of fertilizer application - N45P45K45 and N90P90K90, and without applying the main fertilizer. Seed treatment with Palisander and processing plants Microsensor plant height of winter wheat increased on the background without fertilizers by 3.2 cm (4,5%), against making N90P90K90 - 2.7 cm (3.5%), and in the background making N45P45K45 - 4.2 cm (5.5 %). When treating seeds with Polishance, the coefficient of productive bushiness of plants was 1.94 on the background without fertilizers and tended to increase on the studied backgrounds of fertilizer 1.97-2.01. The yield of winter wheat in the studies was affected by the lack of available moisture for the formation of reproductive organs. At the same time, the effect of both macrofertilizers and microfertilizers, depending on the time of their application, on the yield of winter wheat was very clearly traced. The highest productivity of winter wheat was obtained with the following complex of studied agricultural methods: seed treatment with Polishans (0.2 l / t) + treatment of crops with Macrochance (0.25 l / ha) twice during the growing season-tillering and earing and all this against the background of the main fertilizer N90P90K90. The use of the Macrochance polymicrobial increased the gluten content by 2-4% while increasing the IDC index to 65-74 units, which corresponded to the I quality group.

Specificneed in manganese is a characteristic feature of all plants. At present time, participation of this element in functioning in a number of processes and structures in the plant organism is proved. Indispensabilityof manganese as a component of plant metabolism is evidenced by death of plants aged 2–4 weeks at absolute exclusion of manganese nutrient medium, and symptoms of disorders at all levels of metabolism due to lack of this element. As opposed to symptoms of deficiency which are specific for every element, the signs of excess are more or less the same. In conditions of gradual increase of the concentration of ions as factors of influence, gradual manifestation of plant organism depression is observed: growth inhibition, root dying and leaf chlorosis, etc. Foliar feeding of grain crops including winter wheat with manganese is very important because they have a great need for such elements as manganese and copper. Efficiencyof the types of foliar feeding is connected with the mechanisms of penetration of manganese into the plant cells. Unlike other metals, manganese can be mobilized by sprouts from seed integument: metal absorption from wheat seeds lasts till the seventh day. That’s why, the aim of our work was to investigate the influence of pre-sowing processing of winter wheat seeds with solutions of different concentrations of manganese sulfate for detection of the optimal concentration and studying of phytotoxic influence of the excess manganese action. Vegetation tests were carried out in the laboratory conditions for performing the studies. Winter wheat seeds were steeped into solutions of manganese sulfate in such concentrations as 0.001%, 0.01%, 0.1%, 0.5% and 1%. After that they were couched in multi-component environment (sod-podzol soil). As a control variant, an experiment without treatment was used. The influence of different concentrations on the growth processes such as seed germination, length of the sprout, weight of the plants and their root system was estimated. It was determined that the optimal concentration of manganese sulfate for the pre-sowing processing was equal to 0.001–0.01%. The critical one, at which the phytotoxic action is manifested in growth depression and decrease of sprout biomass, is the use of 0.5–1.0% solution of manganese sulfate for the pre-sowing seed treatment.

The article presents the production experience of winter wheat cultivation using experimental preparations based on nanotechnologies for pre-sowing seed treatment and plant nutrition. Reasonable conclusions of positive influence on biometric indicators of plants of the variant with the use of experimental nanopreparation in pre-sowing treatment of seeds and in two leaf top-dressing (for the phases of tillering and earing) were obtained. As a result, it was found that the biological yield (68.76 C / ha) is higher than the reference value by 3.48 C/ha or 5.3%.
