Summary: The results of our research showed that the use of biological preparations significantly increases the green mass of legumes. The use of preparations contributes to the better development of the plants of alfalfa and clover that is evidenced by the obtained results. It is studied the question of application of biological preparations while growing legumes and the role of nitrogen-fixing microorganisms in increasing the plant productivity. The expediency of using such preparations as Gumat Universal, Azohran, Biocomplex BTU and Emochka on the crops of alfalfa and clover is shown. The purpose of the research is to justify the expediency of using biological preparations as a factor in increasing the green mass of leguminous plants and a source of growing rhizobia on the root system of legumes. The obtained results indicate that the use of bacterial preparations contributes to the increase in the yield of green mass of plants. When analyzing the results of the use of microbiological preparations we see that the increase of green mass on the crops of alfalfa is 1.9 t/ha for Azohran and 3.1 t/ha for Emochka compared to the control option. The use of the preparation Azohran on the crops of clover provided the increase of 1.9 t/ha in the yield of green mass on the unfertilized soil. The increase in the yield of green mass was 2.8 t/ha on the unfertilized soil where the preparation Emochka was applied. The alfalfa rhizosphere has a positive effect on increasing the number and weight of tubers when using biological preparations. The obtained data show that the maximum indicators of the rhizobia increase are noted in the flowering phase of the studied crops. It is studied the question of application of biological preparations while growing legumes and the role of nitrogenfixing microorganisms for soils. The value and importance of legumes as predecessors in the accumulation of atmospheric nitrogen is shown. The effect of application of microbial preparations such as Azohran and Emochka on the crops of alfalfa is examined. It is shown that the use of fertilizers significantly increases the weight of root and crop residues of alfalfa. The use of fertilizers contributes to the development of the root system of crops that is evidenced by the results. The comparison of fertilization systems of the crop shows that the use of the recommended norms of fertilizers not only increases the yield of alfalfa, but also enhances its value as a predecessor by accumulating the organic matter. The evaluation of fertilizers as an important factor positively impacting on relationship between rhizobia and crop nutrient is done. It ultimately determines the bottom line of their symbiosis. As we see the environmentally appropriate crop production has a fairly large arsenal of microbiological benefits that will help a lot to reduce the amount of used expensive and environmentally unfavorable nitrogen and phosphate fertilizers. Thus, fertilization is one of the important factors that largely changes the relationship between rhizobia and crop nutrient that ultimately determines the bottom line of their symbiosis. The best results in the accumulation of atmospheric nitrogen have been obtained in the option with the use of the preparation Emochka and N30P60K60.
