Study was conducted to evaluate the effect of different fertilizer regimes on fungal to bacterial ratio and correlation between the carbon related microbial community and enzyme activities. Result showed that application of bioinoculant with green manure significantly decreased F/B biomass ratio (0.441) which is significantly lower than treatment having sole application of inorganic fertilizer. Application of green manure and bioinoculant has significant positive effect on population of cellulose utilizing bacteria and amylolytic bacteria indicated by significant positive correlation of these microbial groups with enzyme activities. Correlation analysis revealed that amylolytic bacteria were dominant C-related microbial group as they showed significant positive correlation with all microbial communities and enzymatic activities irrespective of fertilizer applications. However, treatment T4 having application of green manure and bioinoculant significantly enhanced the correlation coefficient of amylolytic bacteria with amylase activity. Invertase activity was positively correlated with all enzyme activities in treatment having either single or combined application of green manure and bioinoculant. High significant positive correlation (r=0.874 @p=0.01) was recorded in treatment having bioinoculant application indicated positive impact of bioinoculant on organic matter decomposition in soil. So, it can be concluded that combined application of green manure and bioinoculant directly influenced relative number of bacterial population and interrelationship between enzymatic activities in kharifrhizospheric soil.
