Abstract: A field experiment was conducted during 2010-11 to 2012-13 at Jabalpur, Madhya Pradesh (India) to study the effect of nutrient management and cropping system on productivity and soil microbial growth under different rice based cropping systems in Madhya Pradesh. The 4 different cropping systems (CS1 Green manuring sunhemp-Rice-Wheat, CS2-Rice-Chickpea- Sesame, CS3-Rice-Berseem, CS4-Rice-Veg. pea-Sorghum) and three nutrient managements M1- 100% Organic(1/3 N through each of FYM, Vermicompost and Neem oil cake), M2 -100% Inorganic (100% NPK through fertilizers), M3-INM (50% NPK through fertilizer + 50% N through organic sources) with 3 replications in Strip plot design. The soil of the experimental field was sandy clay loam in texture, neutral in reaction (7.3), normal EC (0.52), low in OC (0.72%), medium in available N (264.05kg/ ha) and P(12.8 kg/ha) and high in K (285.2 kg/ha). The growth of bacteria (48.80 × 105), fungi (41.65 × 103), azatobacter (25.67 × 103), actinomycetes (13.55 × 103) and phosphorous solublizing bacteria (16.65 × 103) cfu g-1 soil was maximum in 100% inorganic nutrient management in rice berseem cropping system during the experiment and improved the rice equivalent yield of this cropping system
