An exponential increase in the human population has drastically reduced length of fallow period (<5 years) widely spread shifting cultivation (Jhum). This increased invasion weeds and decreased soil fertility crop productivity, consequently raised concern food security for local farming communities. The present study was conducted two jhum fallows (FL-10 FL-15) to understand response applications indigenous microbes rock phosphate on levels productivity. results showed greater physicochemical properties FL-15 compared FL-10. Burning significantly pH, avail P, N soil, whereas, same C, MBC SM both sites. Among treatments, synergistic effect microbial inocula improvement biochemical properties, a climactic over control productivity rice yield all Maximum grain recorded followed by concludes that mixture from rhizosphere early regenerating plant is effective increasing can be used as an important tool sustain region.
