Abstract


To sustain higher level of soil fertility and productivity, integrated use of bio- fertilizers and chemical fertilizers along with
organic amendments is advocated because added carbon substrate significantly increases the microbial biomass, leading to
enrichment of soil fertility. All the inoculated treatments were significantly increased the total bacterial population over control
at 40 DAS, 60DAS and post harvest soil. The highest bacterial population was obtained due to BRh. BM1 +CDM. Each of
Bradyrhizobium+CDM or sludge significantly increased the fungal and actinomycetes population over the control (NI).
Maximum actinomycetes population was obtained due to BRh. BM 1+ sludge. Each of Bradyrhizobium strains + PSM gave
highly significant increase in PSM over the remaining treatments at all growth stages of moongbean crop. The soil microflora
ranked in order of total bacteria > actinomicetes > fungi > PSB.
