The viable count of free-living diazotrophic bacteria in different crop rhizospheres varied from 1.11 x 10(4) to 8.5 x 10(5) CFU/g of soil. The majority of the diazotrophs phenotypically belong to either Azotobacter chroococcum, non-A. chroococcum type and to a heterogenous group tentatively named putative nitrogen-fixing (PNF) bacteria. In this study, 25 isolates of the PNF group were screened for their multiple plant growth-promoting (PGP) traits and grouped into 5 PGP types. An isolate, PNF(11) showed promising PGP potential in vitro and was characterized as a species of Achromobacter by 16S rRNA analysis. The isolate PNF(11) along with three other previously isolated PGP bacteria, Azotobacter sp. (AZS(3)), fluorescent pseudomonas (Ps(5)), Bacillus sp. (Bc(1)) were selected for crop inoculation response in green house experiment on Vigna radiata var.T44. Plants from inoculated and control pots were sampled and analyzed at 30, 45 and 60 days after sowing for various vegetative, nodule-related data and yield parameters. The findings indicated that selected isolate of PNF bacteria, and other PGP isolates with multiple activities significantly improve the plant growth parameters, yield parameters of Vigna radiata T44 over control and also show good compatibility with Bradyrhizobium inoculation.
