Rhizobia are known to have specificity for their leguminous host. Bambara groundnut although a legume has shown promiscuous ability by nodulating with many Species of Rhizobia. Bradhyrhizobium spp. were recovered from selected Nigerian soils by trapping them in the nodules of Bambara groundnut (BG) using pot hose experiments.
