PECULIARITIES OF FORMATION AND FUNCTIONING OF SOYBEAN-RHIZOBIAL SYMBIOSIS UNDER THE USE OF NEW B. JAPONICUM CULTURES
Journal Title: Сільськогосподарська мікробіологія - Year 2018, Vol 27, Issue
Abstract
In field conditions, the nodulation and nitrogen-fixing activity of new analytically-selected cultures of B. japonicum AC-15, AC512, PC-18, as well as the productivity of two varieties of soybeans Almaz and Vasylkivska under inoculation by these strains was studied. It has been proved that B. japonicum AC512 strain is the most effective in the formation of symbiosis with soybean, it provides a significant increase in grain yield (10.7-11.5 %) compared with the production strain 634b. The selected strain is a highly competitive (92 %) and technologically advanced, and accordingly, promising biological agent for the production of bacterial fertilizers for soybean.
