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 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 results of assessing the effect of biological preparations and a seed disinfectant on the technological qualities of grain of soft spring wheat Novosibirskaya 31 are presented. The effectiveness of the use of biological plant protection products was studied in the field experiment, laid down in 2020 in the forest-steppe conditions of the Ob region. Pre-sowing seed treatment included the following options: control (without treatment); Trichodermin, P (Trichoderma viride, titer more than 6 billion spores/g), consumption rate – 15 kg/t seed; Sporobacterin, SP (Bacillus subtilis + Trichoderma viride, strain 4097), consumption rate – 0.5 kg/ton of seeds; Scarlet, ME, chemical standard (imazalil (100 g/l) + tebuconazole (60 g/l), consumption rate – 0.3 l/t of seeds. The use of the preparations contributed to an increase in yield by 0.40 and 0.52 t/ha when using Trichodermin and Sporobacterin, respectively, and by 0.08 t/ha when using fungicide Scarlet. In this case, the mass of 1000 grains increased by 0.84, 0.80 and 0.96 g, respectively, relative to the control. The preparations Trichodermin and Sporobacterin had a significant effect on the growth of grain in length and width relative to the control – by 5.4-6.9 and 9.6%, Scarlet – by 10.6 and 13.9%, respectively. Pre-sowing seed treatment contributed to the growth of such indicators of the caryopsis as volume (by 19.6–29.3%), surface area (by 12.1–19.2%), and sphericity (by 6.3–7.8%). To a greater extent, they increased with the use of fungicide Scarlet. Getting larger grain led to an increase in the endosperm content by 0.76–1.14%. A close correlation has been shown between the indicators of the mass of 1000 grains and the linear grain sizes (r = 0.92–0.98), as well as with the grain volume, sphericity and endosperm content (r = 0.98–0.99). Pre-sowing treatment of spring wheat seeds provides grain with improved technological properties.

The microbiota of winter wheat seeds from the North-East of Ukraine was studied by a biological method. Its considerable variability is established over three years (2017–2019). The effect of the treatment agents on most microorganisms of wheat seed microbiota in Ukraine, rather than on its genera and species, is shown. It has been proven that fungicides deleted some species and did not affect the development of others. Chemicals replaced some species or genera of fungi with others or even other microorganisms. Biological seed treatment (Phytosporin-M) has caused less microbiota change than chemical treatment (Maxim 0.25 FS, Rostock, Kinto Duo). Fungicides have replaced the dominance of Alternaria spp. (2017 – 57.8%, 2018 – 63.5%) for the dominance of yeast (Rostock – 54%) and Aureobasidium pullulans (Maxim 0.25 FS – 84.2%) in 2017, bacteria (Maxim 0.25 FS – 72.3%, Rostock – 53.8%) – in 2018. A. pullulans dominated in the microbiota of winter wheat seeds in 2019. The highest amount of A. pullulans was noted for the treatment of seeds by Phytosporin-M (85.9%). The biological seed treatment reduced the amount of Nigrospora spp. and Alternaria spp. Several times (3 and 5, respectively), chemical agents did not give Nigrospora spp. germination reduced the amount of A. pullulans, Alternaria spp. in 2019. Maxim 0.25 FS, Rostock 50%, and Kinto Duo delayed seed germination and seedling development on agar medium and soil, whereas Phytosporin-M – on the contrary, promoted the growth of seedlings and significantly exceeded control.

The results of studies of scientifically grounded use of microelements in sweet pepper crops, as an important factor in increasing the yield of vegetable crops and improving the quality of products, are presented. The purpose of our research was to substantiate the influence of the use of trace elements in the technology of sweet pepper cultivation on the growth and development of plants, the productivity and quality of the products of this culture. The experimental part of the work was carried out in 2014-2019 in the subzone of light chestnut soils of the Volgograd region. Experiments on the study of trace elements were carried out by pre-sowing seed treatment and foliar feeding of plants. Chemically pure compounds of manganese sulfate, zinc sulfate, copper sulfate, ammonium molybdate, boric acid were used as microelements. The use of trace elements in the dry-steppe zone of the Lower Volga region is an important agricultural technique that helps to accelerate growth, development, increase productivity and improve the quality of pepper fruits. It is recommended to carry out pre-sowing treatment of seeds with solutions of boric acid (0.29 g / 1 l of water), copper sulfate (0.20 g / 1 l of water) and manganese sulfate (0.16 g / 1 l of water) (the ratio of the weight of seeds to the solution 1: 2) as a way to increase seed vitality, speed up yield and improve seedling quality. In order to increase the yield and improve the quality during the budding period of peppers, it is necessary to carry out foliar dressing, first of all, with solutions of boric acid (0.29 g / 1 l of water), ammonium molybdenum (0.10 g / 1 l of water), water consumption 1 l / 10 m2. Due to its high efficiency, simplicity and availability, pre-sowing seed treatment and foliar feeding of plants with microelements will find wide application in vegetable growing.

The Magnetic Field

The purpose of the research was to establish the mechanism of the magnetic field impact on seeds to determine the most effective mode of pre-sowing treatment of seeds in a magnetic field and design parameters of the device for magnetic treatment of seeds. It is established that under the influence of a magnetic field the rate of chemical reactions occurring in plant cells is accelerated, solubility of salts and acids increases, and permeability of cell membranes accelerates the diffusion of molecules and ions through them. This leads to an increase in the concentration of ions in the cell and oxygen molecules and the growth of water absorption of seeds. Pre-sowing seed treatment promotes increased germination by 25-40%, and germination by 30 - 35%. The most effective pre-sowing treatment of seeds in a magnetic field is a magnetic induction of 0.065 Tl with four reversal magnetization, a pole division of 0.23 m and a seed movement speed of 0.4 m/s. With this mode of treatment, crop yields increase by 20–25%.
