SYMBIOSIS OF NODULE BACTERIA BRADYRHIZOBIUM JAPONICUM AND SINORHIZOBIUM FREDII WITH SOYBEAN PLANTS ISOLATED FROM SOILS OF UZBEKISTAN

The slow and fast-growing Rhizobia bacteria Bradyrhizobium japonicum and Sinorhizobium fredii were isolated from the experimental fields of Uzbekistan, where rice and soybeans are grown, from the soil and from the nodules of soy roots upon repeated inoculation of these bacteria with local soybean varieties, it has been demonstrated that these bacteria form nitrogen-fixing nodules in plant roots and enter into symbiotic activity.
