Use of environmentally safe strains of nitrogen-ﬁxing microorganisms in cultivation of alfalfa in Central Yakutia
The paper presents the results of tests of nodule bacteria and associative rhizobacteria strains on alfalfa variety Yakutskaya zholtaya. The indexes were increased: the green fodder yield by 11 %, the content of crude protein in the green fodder by 1,7 %, the humus content in the soil by 0,4 % due to the inoculation of alfalfa seeds by the strains of nodule bacteria. The inoculation of alfalfa seeds by the strains of associative rhizobacteria Serratia and Pseudomonas favorably inﬂuences on improvement of the forage quality of alfalfa.
