    Aim: This study was carried out to evaluate the long-term impact of manuring, fertilization and liming on soil resilience, enzyme activities and system productivity under changing climate scenarios. Methodology: The soil samples were collected from 67 year old long-term experiment going on, at Birsa Agricultural University, Jharkhand during 2022- 23 under maize-wheat cropping system from seven treatments, viz. T : control, T : 100 % N, T : 100 % FYM, T : ½ (N+FYM) + P + K , T : 100 % NPK,1 2 3 4 X/2 Y/2 5 T : Lime + NPK, T : Lime + FYM +P + K . To assess soil resistance and resilience, surface samples were subjected to with and without heat stress6 7 (A-X) (B-Y) -1 (48±2°C for 80 hrs) and substrate addition (0.02 g glucose g soil). Results: Application of FYM/lime with NPK significantly improved bulk density, pH, SOC and system productivity. The highest enzyme activities and cumulative respiration were observed in lime + FYM + P + K treatment. It exhibited the highest resistance index (0.92) and resilience index (0.34).(A-X) (B-Y) Interpretation: The integrated use of inorganic, organic along with liming proved to be a useful management strategy for maintaining soil quality, resistance and resilience, and crop productivity in acid soil of Jharkhand
