Abstract
Nine rhizobial strains isolated from the root nodules of <em>Cicer arietinum, Vigna radiata, V. mungo, Samania saman, Sesbania sesban, Leucinia</em> sp., <em>Prosopis cineraria</em> and <em>Medicago sativa</em> were used to study their effects on root-infecting fungi viz., <em>Macrophomina phaseolina, Fusarium solani</em> and <em>Rhizoctonia solani</em>. In dual culture plate assay, strains of Bradyrhizobium sp., and R. meliloti were found to inhibit radial growth of <em>M. phaseolina, F. solani</em> and <em>R. solani</em> producing zones of inhibition. <em>Bradyrhizobium</em> sp., and <em>R. meliloti</em> either used as seed dressing or as soil drench significantly suppressed root-rot infection caused by <em>M. phaseolina, F. solani</em> and <em>R. solani</em> in okra, a non-1eguminous crop under greenhouse conditions. Biomass of plants was also higher in the presence of rhizobia.
