Inoculation of seeds with Rhizobium tropici and foliar spraying of Azospirillum brasilense, either alone or in combination, resulted in an additive effect that increased shoot biomass, nitrogen accumulation, thousand-grain weight, and grain yield of common bean.
Association of rhizobia with other plant growth-promoting bacteria (PGPB), such as Azospirillum, have the potential to increase crop yields. This work aimed to assess how Rhizobium tropici and Azospirillum brasilense alone or in combination, affect the growth and yields of common bean grains (Phaseolus vulgaris L.). In a field experiment, R. tropici and A. brasilense were inoculated on seeds, alone or in combination, associated or not with foliar spraying of A. brasilense. Shoot biomass, nitrogen accumulation, thousand-grain weight, and grain yield were evaluated. Application of A. brasilense, on seed or by foliar spraying, and seed inoculation of R. tropici, had an additive effect, increasing biomass and accumulated nitrogen, thousand-grain weight, and grain yield.
