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.

The article presents the results of the experiment on the efficiency of different rates of herbicide Prima Forte 195 (0.5; 0.6 and 0.7 l/ha) under different application methods of plant growth regulator of a natural origin Wuxal BIO Vita (1.0 l/ha, 1.0 l/t) (spraying of vegetative plants, pre-sowing seed treatment) on weed infestation of emmer wheat. The objects of the research were emmer wheat plants (Triticum dicoccum (Schrank) Schuebl.) of the cultivar Holikovska (originator – the Plant Production Institute named after V.Ya. Yuryev, Ukraine), herbicide Prima Forte 195, с.е. (Syngenta) (active substances: florasulam 5 g/l, aminopyralid 10 g/1, 2- ethylhexyl alcohol 2.4-D 180 g/l), and plant growth regulator Wuxal BIO Vita (Unifer) (active substance – extract from seaweed Ascophyllum nodosum, nitrogen (N) – 52 g/l, manganese (Mn) – 38 g/l, sulphur (S) – 29 g/l, iron (Fe) – 6.4 g/l, zinc (Zn) – 6.4 g/l). Experiments were performed in the conditions of the crop rotation of the Department of Biology on the experimental field of Uman National University of Horticulture during 2017–2018 according to the scheme: without the use of preparations (control I), without the use of preparations + manual weeding during the growing season (control II), Prima Forte 195 at the rates of 0.5; 0.6 and 0.7 l / ha applied separately and together with Wuxal BIO Vita at the rate of 1.0 l/ha, applied separately and at the background of pre-sowing seed treatment with Wuxal BIO Vita 1.0 l/t. It was found that the herbicide Prima Forte 195 had the highest efficiency when it was applied at the rates of 0.5; 0.6 and 0.7 l/ha in combination with the plant growth regulator (PGR) Wuxal BIO Vita at the rate of 1.0 l/ha at the background of pre-sowing seed treatment with the same PGR at the rate of 1.0 l/t. Thus, the technical effectiveness against dicotyledonous weeds was on average within 86-88 % depending on the rate of the herbicide and the method of using PGR. Therefore, there is every reason to state that the herbicide Prima Forte 195 (0.5-0.7 l/ha) is effective in destroying the vast majority of dicotyledonous weeds in emmer wheat

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.

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.
