Abstract: The experiment was conducted during 2016-17 at Nagarjun medicinal plants garden Akola, Dr. PDKV, Akola. The experiment was laid out in Randomized Block Design with nine treatments replicated three times. The integrated nutrient management influenced the soil fertility status under kawach beej. Based on the observations as defined in programme of research work significantly higher organic carbon (6.63 g kg^-1), available N (190.56 kg ha^-1), P (28.56 kg ha^-1) and K (342.70 kg ha^-1) were recorded with 5 t FYM ha^-1 + N:P @ 25.0 : 50 kg ha^-1 followed by 5 t FYM ha^-1 with N:P @ 12.5: 25.0 kg ha^-1. The maximum availability of micronutrients viz., Fe (4.96 mg kg^-1), Mn(3.04 mg kg^-1), Zn (0.73 mg kg^-1) and Cu (2.39 mg kg^-1) were recorded with 5 t FYM ha^-1 + N:P @ 25.0 : 50 kg ha^-1 followed by 5 t FYM ha^-1+N:P @ 12.5: 25.0 kg ha^-1. Similarly use of 5 t FYM ha^-1 with N: P @ 25.0: 50 kg ha^-1recorded higher microbial biomass carbon (185.19 mg kg^-1) as compared to other treatments indicating the importance of organics for enriching soil quality. The use of organics <em>viz.</em>, FYM with chemical fertilizers (N and P) resulted improvement in chemical and biological properties which ultimately helps in soil health and crop productivity. The results revealed that the integrated nutrient management not only improved the soil properties like pH, EC, calcium carbonate and organic carbon but also improved the soil fertility.
