Abstract: The present investigation was carried out at the research farm of JNKVV under AICRP on STCR, Department of Soil Science and Agricultural Chemistry, College of Agriculture, JNKVV, Jabalpur (MP). The experiment was undertaken on Typic Haplustert soil on the field of soil science Department JNKVV Research Farm, Jabalpur. The experiment was taken under the ongoing project of AICRP on STCR, taking six different treatments based on targeted yield of rice and wheat cropping sequence. During kharif season in rice crop with 6 treatments as RT₁ (Control), RT₂ (GRD @ 80:50:30 NPK kgha^-1), RT₃ (Targeted Yield 5 t ha^-1), RT₄ (Targeted Yield, 6 t ha^-1), RT₅ (Targeted Yield,5 t ha^-1 with 5 t FYM ha^-1) and RT₆ (Targeted Yield 6 t ha^-1 with 5 t FYM ha^-1,) .During rabi season in wheat crop, 6 treatments as WT₁ (Control), WT₂ (GRD @ 120:80:60 NPK kgha^-1 ),WT₃ (Targeted Yield 4.5 t ha^-1), WT₄ (Targeted Yield, 6 t ha^-1), WT₅ (Targeted Yield,4.5 t ha^-1 with 5 t FYM ha^-1) and WT₆ (Targeted Yield 6 t ha^-1 with 5 t FYM ha^-1) were tested under randomized block design with four replications. The pH value recorded at 0-20 cm soil depth in rice crop at 30, 60, 90 DAS and at harvest under different treatments was slightly decreased than the initial soil pH value of 7.78. In case of wheat, different treatments did not give significant influence on pH of surface (0-20 cm) soils at different time interval. In case of rice, EC values at 0-20 cm depth showed increasing trend over passage of time of growth as compared to initial value. Wheat crop showed increasing trend of EC at 30 and 60 DAS and then decreasing trend there after again. Application of nutrient in integrated manner increased organic carbon at 0-20 cm at different time intervals in both rice and wheat. Maximum plant height, tillers/hills and penicle length were recorded under RT₆. The highest yield of grain and straw was recorded in treatment RT₆ having higher target yield 5.57 t ha^-1 and 8.53 t ha^-1respectively. Maximum protein content was also recorded under RT₆
