The field experiment was undertaken to investigate the long-term application of manures and fertilizers on soil microbial communities and their biological activities in the rhizosphere and bulk soil. The research was conducted at ZARS, GKVK, Bangalore. There were 10 treatments and three replications in an RCBD design. Soil enzyme activities viz., dehydrogenases, acid and alkaline phosphatases and urease activities were found to be significantly higher in the treatment with application of 20t of FYM ha-1 compared to recommended NPK alone.
