The estimation of two methods of soybean inoculation with nodule bacteria - seed inoculation and introduction into soil of an adequate amount of inoculation suspension at the time of presowing cultivation - has shown the benefits of the last of the above methods. One is confirmed by more number of root nodules, more intensity of atmospheric molecular nitrogen fixation, and highest grain yield of soybean formation. It is noted, that on the areas, where soybean was sown in previous year and was inoculated with active rhizobia strains, symbiotic properties of the microorganisms - virulence and nitrogen fixing activity - are stored in the following year. The estimation of efficiency of three perspective transposone mutants B.japonicum 646 demonstrated the benefits of two (T66 and 3-11) over the standard strain 634b.
