[Competing ability of Rhizobium trifolii strains and efficiency of clover nitraginization on spent peat mosses].
The competing ability of active strains of clover nodule bacteria was assayed in vegetation and field experiments. The competing ability of the industrial strains 311a and 347a was found to be sufficiently high. These strains increased the yield of clover on exhausted turf peats of the Kirovsk Region by 26--29%. The stimulating effect was observed also with new strains 313b and 329b. The optimal dose for inoculation of clover seeds in these conditions is 50,000 nodule bacteria per one seed. Inoculation should be conducted by a strain with a high competing ability.
