A pot experiment was conducted under green house conditions to study the influence of microbial consortia on rhizospheric soil enzymatic activities at different intervals of sorghum growth. Microbial consortia along with different doses of chemical fertilizers and FYM were added to sorghum (CSV-27). Different soil enzymes viz., acid phosphatase, alkaline phosphatase, dehydrogenase enzyme and urease enzyme activity were monitored at zero DAS, 45 DAS, 90DAS and 120DAS in potculture. Treatment T10 (75% RDF + Microbial consortium-2 +FYM) showed significantly highest enzymatic activity of all the enzymes at all intervals of crop growth compared to other treatments. While, except urease all the other three soil enzymes like dehydrogenase, acid phosphatase and alkaline phosphatase activities were significantly lowest in T11 (100% RDF). Microbial consortium-2 showed maximum enzymatic activity compared to microbial consortium-1.
