The efficiency of the presowing soybean inoculation with nodule bacteria at direct seeds bacterization or introduction of inoculum to the soil at presowing cultivation as well as the ability of rhizobia remained in the soil to the next year to form active symbioses with soybean plants was studied. The liquid bacterial cultures of production strain Bradyrhizobium japonicum 634b and three perspective Tn5-mutants of B. japonicum 646 were used. The introduction of the inoculum to soil was shown to be more efficient during both years of investigations as compared with the seeds inoculation which resulted in higher number of nodules formed, their nitrogenase activity and greater soybean seeds yield. Two of three studied Tn5-mutants had surpassed the standard strain by the efficiency indices.
