Gram-positive rod shaped aerobic bacteria related to the genus Rhizobium sp was isolated from the root nodules of cowpea plant and mass multiplied. The cell count was characterized periodically and the cell suspension was mixed with vermicompost at 1×108 cells per ml for 1 gram of vermicompost and the mixture was tested in pot culture studies. Higher productivity of cowpea (Vigna unguiculata) was observed.
