Cowpea, Inoculation, Carriers, Rhizobium


Rhizobium survival in bagasse and soil carriers was examined at 4 and 30oC. Only short-term storage (three days) was possible at 30°C but good survival was observed up to 9 days at 4°C with both carriers. In field studies, little difference was evident between carriers in root representation by homologous strains. The inoculant comprising two strains isolated from the experimental area gave the highest strain representation in the nodules.
