Abstract: Field experiment was conducted in Rabi season of 2016-17 at Research Farm of at AICRP on Integrated farming System. Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani entitled “Enzyme activity and Soil Biological Properties influenced by application of Different Nutrient sources in Onion under Vertisols of Maharashtra”. The experiment was laid out on Vertisols with eight treatment combination, replicated three times in randomized block design. The treatment consists of T1- (50% recommended NPK + 50% N through FYM + Inorganic sources of micronutrient as per soil test), T2- (Different organic sources each equivalent to 1/3 recommended N (FYM + Vermi-compost + non edible oil cake), T3- (T2 + Intercropping of trap crop), T4- (T2 + Agronomic practices for weed and pest control (No chemical, pesticide and herbicide), T5- (50% N as FYM + Bio-fertilizer for N + Rock phosphate to substitute the P requirement of crops + Phosphate solubilizing bacterial culture), T6- (T2 + bio-fertilizer containing N and P carriers), T7- (100% NPK + Secondary and micronutrient based on soil test (ZnSO4 10 kg + S 25 kg), T8- (Absolute control). The results reneged out from the experiment field stated that the maximum population of bacteria 348.33 x 107 cfu g -1 soil, fungi 20.00 x 104 cfu g-1 soil and Actinomycetes 105.33 x 105 cfu g-1 soil was recorded by treatments T6- (T2 + bio-fertilizer containing N and P carriers), than all other treatments. The dehydrogenase enzyme activity 343.33 µg TPF 24 h-1 g-1 soil and microbial biomass carbon 345.66 µg g-1 soil was recorded by treatments T1- (50% recommended NPK + 50% N through FYM + inorganic sources of micronutrient as per soil test) at harvest of onion crop. The onion yield was recorded maximum by application of treatment T6, T2 and biofertiilizers enter N and P carries.
