Response of centrosema to inoculation with local Bradyrhizobium sp. strains

Abstract

Five plant genotypes of centrosema (Centrosema sp.) were tested against local Bradyrhizobium sp. strains with regard to symbiotic nitrogen fixation in sand-nutritive solution in a greenhouse trial. The response to inoculation was positive. The amount of nitrogen fixed was a function of plant genotype, strain inoculated and plant genotype x strain interaction.
