Abstract: The field experimental was conducted at the Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during Kharif 2018-2019. The soil sample was collected at 0-15cm and 15-30cm soil depth. The treatments consisted of organic and inorganic combination of T1[Control(N0P0K0), T2 [100% N through Organic Source (1/3 FYM, 1/3 vermicompost, 1/3 Neem cake)], T3 (75% N through Organic Source + 10% foliar spray of Vermiwash and Cow Urine at 25 – 30 DAS and 50-60 DAS), T4 (50% N through Inorganic + 50% N through Organic), T5 (75% N through Organic + 25% N through Inorganic), T6 (100% N through Inorganic). The highest BD was recorded in T1 and T6 treatments (1.33Mgm-3) at 0-15 cm and at 15-30cm T4, T5, T6 (1.42Mgm-3). Lowest BD was recorded in T2 treated plot at both depth of the soil the value was 1.31 Mgm-3 (0-15 cm) and 1.40 Mg m-3 (15- 30 cm). The maximum pH was recorded in the treatment plot of T4 and T6 that was 7.74 in surface soil, while the maximum value (7.78) of sub-surface soil pH was recorded in the T1 and T4. Similarly, the minimum soil pH was recorded in the treatment of T2 at 0-15cm depth and T6 at 15-30cm depth, the value was (7.71) and (7.75) respectively. The EC observed in T4 at both depth of soil compare with other treatments the value was 0-15cm (0.245dSm-1) and 15-30cm (0.183 dSm-1). The soil organic carbon was maximum observed in T2 at both 0-15cm (6.97 g kg-1) and 15-30cm (6.71g kg-1) depth. The available N higher in T3 (258.64 kg ha-1) at 0-15 cm and T4 (247.49 kg ha-1) at 15-30 cm. The available P was maximum in treatment T2 at 0- 15cm (20.82 kg ha-1) available Phosphorous at 15-30cm treatment T3 recorded maximum which was (19.27 kg ha-1). The value of available potassium was maximum recorded in treatment T4 (378.86kg ha-1) at surface soil and T2 at subsurface soil (349.05 kg ha-1).
