Abstract
The plant production without mineral fertilizers and pesticides application, and the ability of microorganisms to provide the plants with all essential nutrients, anticipate that the microbial fertilizers will take up significant place in agricultural production (Tyler et al.,2008). The aim of this paper was to investigate the effect of Rhizobium leguminosarum bv. phaseoli and Azotobacter chroococcum inoculation, individually and in the mixture with Streptomyces sp., on the yield parameters of common bean and microbial activity in rhizosphere. Microbial analysis were done by standard CFU method and total number of bacteria, number of actinomycetes and azotobacter were determinated. Dehydrogenase activity was estimated spectrophotometricaly. In the stage of full maturation of common bean number of legume per plant and grain mass per plant were enumerated as basic yield parameters. Total number of bacteria and number of azotobacter were greater on variant with azotobacter inoculation. Dehydrogenase activity was greater on the variant with polyvalent inoculum, while the number of actinomycetes was greater on the variant with rizobium. Number of pods per plant was significantly increased where rhzobium and azotobacter were applied, but mixture of inoculants did not provide statistically significant resultates. Inoculation positively influenced the grain mass per plant. Where the rhizobium and mixture of inoculants were applied increase of grain mass was statistically significant. .
