Abstract: Objective of this study was to assess the inoculation effect of actinobacterial, rhizobium and plant growth promoting rhizobacteria consortium on rhizosphere soil properties in the soybean. For this study, two isolates of each Actinobacteria, Rhizobium and PGPR microbial inoculants as mono-inoculation and their combination as co-inoculation which proved to be highly efficient in initial screenings under controlled conditions in soybean under glass house conditions were further used for evaluation under field conditions having Vertisol type of soil. Actinobacteria, Rhizobium and PGPR Consortium showed significant difference in improving plant growth attributes and yield components of soybean at different growth stages. Among the microbial inoculants tested Actinobacteria, Rhizobium and PGPR Consortium inoculated plants showed higher N, P and K uptake (206, 13 and 101 kg /ha, respectively) and there was no significant difference with respect to soil pH, EC and organic carbon content in soils after crop harvest of soybean. In soils after crop harvest actinobacteria, Rhizobium and PGPR consortium recorded the highest available N, P and K 239, 16.6 and 302 kg /ha, respectively). This inoculants also recorded higher population of bacteria (36.5 x 105cfu g /soil) fungi (20.6 x 103cfu g /soil) and Actinomycetes (Bacillus sp.) (15.4 x105cfu g /soil). Among the mono and co-inoculation, co-inoculation of Actinobacteria, Rhizobium and PGPR Consortium were found best for improving the yield of soybean and also soil health.
