Abstract:
This field experiment was established during rabi season of 2020-21 at Research Farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur in an on-going research experiment of AICRP on STCR (Soil test and crop response) initiated during 2008, to assess the vertical variability in properties of post-harvest soil under rice-wheat cropping system. This study was consisted of six treatments of nutrient management based on STCR (T₁: Control; T₂: RDF; T₃: TY- 50 and 45 q ha^-1 for rice and wheat; T₄: TY- 60 q ha^-1; T₅: TY- 50 and 45 q with FYM 5 t ha^-1 for rice and wheat and T₆: TY- 60 q with 5 t FYM ha^-1) at different soil depths (0-15, 15-30 and 30-45 cm). Results revealed that STCR based nutrient management practices significantly affected the variability of physico-chemical properties of soil at different soil depths except soil pH. Highest values of EC, OC, available N, P, K and S and CEC were obtained under treatment T₆, while content in calcium carbonate of soil was obtained highest under control. It was also revealed that the values of different soil properties were decreased with increased in soil depths except soil pH, calcium carbonate and CEC of soil.
