Abstract At the present stage, soybean is one of the most popular crops in crop production. To increase the production of soyabean products, it is necessary to significantly increase its yield, which can be realized in the application of fertilizers. Nowadays preference is given to preparations made on the basis of natural raw materials. Therefore, the study of microbial agents Agat-25K and Phytosporin-M on individual physiological parameters of soybean in the main phases of ontogeny and its productivity is an actual problem of the present. It was established that the preparation Phytosporin-M in the phase of formation of the trigeminal layer effectively stimulated the length of the head and lateral roots. In the flowering phase, Phytosporin-M and Agat-25K have increased the length of the stem, exceeding the control index by 126,3% and 71,2% respectively. The mentioned fertilizers in this phase also had a positive effect on the parameters of the length of the main, lateral soybean roots and on the number of tubers on the roots. In the ripening phase, Phytosporin-M stimulated the plant height and height of attachment most effectively, exceeding the control parameters by 66,3% and 34,7% respectively. The application of these biopreparates also had a positive effect on the number of fetal nodes and the formation of beans. Thus, in the control, the number of fetal nodes per plant was on average 8,0 pieces. During the treatment, the highest rates were noted with Phytosporin-M and amounted to 13,5 units, which exceeded the control indicators by 68.8%. At the same time, the number of fetal nodes on soybeans for processing with Agat-25K was 11,2 pieces, which exceeded control by 40%. The highest yield of soyabean was observed in the processing of seeds by Phytosporin-M and amounted to 2.99 tons/hа, exceeding the control indicators by 39.1%, respectively. Then, as the yield of soybeans for treatment with the Agat-25K drug was 2,59 t/ha, which exceeded the control rate by 20,5%. Thus, Phytosporin-M and Agat-25K may be promising biological products for growing leguminous crops.
Key words length of the stem, length of lateral roots, number of lateral roots, number of tubers, height of plants, height of attachment of the lower beans, number of fruits bearing nodes per one soyabean plant.
