The dynamics of root nodules formation, accumulation of their mass, growth processes, seed production and productivity of soybean cultural, inoculated with Tn5-mutants of bacteria of species Bradyrhizobium japonicum was studied in field experiments. It was investigated that presowing treatment of seeds with the help of nodule bacteria of these strains stimulated formation of symbiotic system, growth and development of plants. The most effective bacterization was with Tn5-mutants D1 that was manifested in increasing productivity of seeds of this variant at 44,87% in comparison with control and at 25,68% in comparison with production strain 634b.
