The results of research on the study of the impact of agents of biochemical and microbiological origin of production LLP R&D Enterprise "5 Element" on the production process, the structure of yield and yield of corn under drip irrigation are highlighted. It is determined, that the highest yield of corn can be obtained by holding the pre-sowing treatment of seeds with nanobiostimulator of plant growth "V-Agro. Seeds" and the double treatment of vegetative plants with a solution of concentrate of products of vital activity of nitrogen-fixing soil algae. The combined use of the agent "V-Agro. Seeds" and the solution of concentrate of products of vital activity nitrogen-fixing soil algae provides a corn yield of 16,1 t/ha, which is by 5,5 t/ha, or 51,9 % more than in the absolute control (without seed treatment and foliar treatment of plants).  It is also established that the separate use of agents both for seed treatment and plant treatment during the growing season is also an effective measure. The single seed treatment with nanobiostimulator of plant growth "V-Agro. "Seeds" helps to increase the yield of corn by 1,6 t/ha, or by 15,1 %. A similar effect was obtained using for processing seeds of the biological product Soil Algae (live culture in powder form), where the increase in yield was 14,1 % (1,5 t/ha). It is determined that the use of agents for foliar application is more effective than pre-sowing seed treatment. The double spraying of corn plants, with respectively, 2 % and 4 % solution of concentrate of products of vital activity of nitrogen-fixing soil algae provides crop yields by 3,2 t/ha, or 30,2 % compared to the control. The use of nanobiostimulator of growth plants "V-Agro. Leaf processing" for foliar application provides the yield increase up to 2,8 t/ha, or 26,4 %. The biggest average weight of one cob corn was obtained due to the agricultural measure, which involves pre-sowing seed treatment nanobiostimulator of plant growth "V-Agro. Seeds" and the double treatment of vegetative plants with a solution of concentrate of  products of vital activity of nitrogen-fixing soil algae made it possible to get a cob with an average weight of 248,4 g, whereas in absolute control (without seed treatment and foliar treatment of plants) – 174,5 g.

The study of the dynamics of plant growth and yield of vegetable crops (carrot variety Absheron winter (Daucus carota subsp. sativus (Hoffm.) Schьbl.) and radish variety Virovsky white (Raphanus sativus var.radicula Pers.)) was conducted in the field conditions after presowing exposure to different temperatures: I option – sowing of seeds exposed to low temperatures (for 15 days the swollen for 24 hours seeds were kept at a temperature of 0±1°С); Option II - sowing of seeds exposed to variable temperatures (for 5 days, the swollen for 24 hours seeds were exposed to variable temperatures of + 20°C (8 hours) and 0±1°C (16 hours) and then 10 days at a temperature of 0±1°C; K1 – sowing dry seeds; K2 – sowing soaked seeds. The impact on the seeds of low and variable temperatures caused an increase in growth processes, both in radish and carrot. Both studied crops showed a tendency to increase the yield to a greater extent when exposed to swollen seeds with variable temperatures. Thus, the average weight of radish crops exceeded the control variant by 47.1% and carrots by 27.6%. The yield of root crops per m2increased by 36.4% for radish and 30.0% for carrot. To increase the productivity of vegetable crops, we recommend using the studied methods of pre-sowing seed treatment in practice.

Soybean is an important crop in Brazil. Nonetheless, there are no reports on the use of plant growth regulator potential in relation to this crop in the national literature. To better understand the role of these compounds, a pot experiment was carried out to study effects of GA3 and cytokinin on the vegetative growth of the soybean. GA3 (50 mg L-1) was applied as seed treatment, leaving plants with water application as control. GA3 (100 mg L-1) and cytokinin (30 mg L-1) were sprayed on leaves at the physiological stage V3/V4, and 15 days after, cytokinin (30 mg L-1), also as foliar spray. Seed treatment decreased plant emergence and initial soybean root growth, but as the season progressed, differences in root growth disappeared; plants were shorter, and presented a decrease in the number of nodes, in stem diameter, in leaf area and in dry matter yield. Conversely, foliar application of GA3 led to an increase in plant height, first node height and stem diameter. Leaf area and dry matter production also increased as a result of GA3 foliar application. There was no effect of exogenous gibberellin and cytokinin on the number of soybean leaves, number of stem branches and root dry matter. Joint application of gibberellin and cytokinin tended to inhibit gibberellin effects. Cytokinin applied to leaves during soybean vegetative growth was not effective in modifying any of the evaluated plant growth variables.

In order to improve soil fertility, increase the productivity of agricultural crops, including alfalfa, and to make the best use of mineral fertilizers it is expedient to carry out liming in the range of 1.0-1.5 under hydrolytic acidity. It provides an increase in the amount of 1.2-1.8 tons of feed units per hectare of rotation area. The mobility of toxic elements of aluminum and manganese decreases in the limed soil. These processes contribute to nodule formation and an increase in the nitrogen fixation of alfalfa. The intensified activity of nitrogen fixation processes occurring in the root zone of plants can be achieved with the use of physiologically active substances characterized by auxin-cytokine activity. Both associative and symbiotic nitrogen fixation processes are enhanced by virtue of plant growth stimulants. These preparations are the analogs of exogenous phytohormones of cytokine, gibberellin and auxin effect, and unsaturated fatty acids, carbohydrates, amino acids. They are used for pre-sowing seed treatment and top dressing of plants. The conceptual direction of the development of biotechnologies and biological nitrogen fixation in agriculture is the development of preparations in order to stimulate growth, increase the production of legumes. Creation is important the original complex compositions of multifactorial action, which combine the properties of plant growth regulators, fertilizer elements, means of plant resistance to stress and diseases. In light of this, the study of agrobiological methods of growing forage crops. Including alfalfa, with the use of plant growth regulators, as well as their combination with biological preparations based on active strains of nodule bacteria. It aims to improve the nitrogen nutrition of plants in the monoculture. Important is also a significant increase in the level of the biological conversion of atmospheric nitrogen into organic nitrogen-containing compounds. Is particularly relevant for the creation of sustainable production of feed raw materials and maximization of the biological potential of plants under the unstable soil and climatic conditions. When growing agricultural crops, biologically fixed nitrogen is extremely important for legumes since this reduces the use of mineral fertilizers and the cost of production. Perennial legumes, in particular, alfalfa, are not only a source of high-protein feed, but they are the best precursors, especially for grains, cereals, and industrial crops. They not only increase their yields but also improve the soil structure and fertility. According to the results of our research, under the conditions of Right-Bank Forest-Steppe, the best conditions for the symbiotic activity of alfalfa seedlings were created under the conditions: Non-perishable growing method. The introduction of the herbicide in the year of sowing. Conduct calcining the full norm. Use of pre-sowing seed treatment with bacterial preparation risobofit with plant growth regulator Emistim S. Under these conditions, the maximum indicator of biologically fixed nitrogen is formed-236.1 kg/ha. Key words: alfalfa sowing, liming of soil, inoculation, growth promoter, biological nitrogen.
