A field experiment was conducted during kharif season 2015 in alluvial soil at farmer field, in village Loharapur, Varanasi, to study the soil microbial biomass, dynamics and selected enzyme activities as influenced by farm yard manure and inorganic fertilizer. The soil microbial biomass carbon; nitrogen and phosphorous was improved significantly with the different treatments. Highest soil biomass carbons, nitrogen, phosphorous were recorded with the combined application of inorganic nutrients and farm yard manure (T7) over the remaining other treatments. The highest soil biomass were recorded in treatment T7 and lowest in T1. Maximum soil enzymatic activity such as urease 227.38μg UH g-1 soil h-1, dehydrogenase 175.12μg TPF g-1 soil/day and phosphatase 112.25ìg p-NP g-1 soil/h were observed with T7 (NPK+2 t ha-1). Enzymatic activities were positively and significantly correlated with content of organic carbon. As a consequence application of NPK and FYM combination was more effective on increasing rice productivity targeted to 40 q/ha and 50 q/ha and soil nutrient status than single application of FYM or chemical fertilizer.

Keywords: SMBC,SMBP, SMBN, Dehydrogenase, Phosphatase and Urease activities.
