Testing rhizobium strains of soybean of Bradyrhizobium japonicum and Sinorhizobium fredii species
Presented the study results of high active Rhizobia strains (BB-49, TB-643 of fast growing species Sinorhizobium fredii and 648a of the slow growing species Bradyrhizobium japonicum) in the conditions of monsoon climate of Primorsky krai. The most effective was the bacterial preparation, created on the basis of S. fredii, which is applied while planting soybeans. It provided a higher seed yield due to the accumulation of biological nitrogen from atmosphere in plants and increased resistance to fungal diseases during the vegetation.
