Abstract
There is considerable interest in improving nitrogen fixation in legumes to increase soil fertility, particularly in the developing countries. The effect of inoculation of peanut (Arachis hypogaea L.) seed with Bradyrhizobium sp. USDA 3187 was examined under field conditions. In order to determine nodule occupancy, bacterial cells from surface-sterilized nodules of inoculated plants were isolated and characterized by their intrinsic antibiotic resistance and by agglutination test. Results obtained revealed that peanut roots were nodulated by native strain rather than the introduced one, indicating that strain USDA 3187 was not as competitive as naturalized peanut rhizobia. Data also showed that there were no significant differences in nodule dry weight, plant dry biomass, nitrogenase activity and seed yield between uninoculated and inoculated treatments.
