A field experiment was conducted in 2006-07 and 2007-08 to assess the effect of FYM, biofertilizers and zinc on microbial biomass and enzyme activities in soil at 30 DAS of maize. Bio-fertilizers like Azotobacter and VAM were utilized. Application of FYM alone and in combination with biofertilizers resulted into increase in the microbial biomass (carbon, nitrogen and phosphorus) and enzyme activity (Dehydrogenase, alkaline and acid phosphatase) in soil. Application of zinc failed to affect microbial biomass and enzyme activity in soil.
