The experiment on long term effect organic, inorganic and integrated nutrient management on performance of rice-wheat cropping system was conducted from 2004-05 to 2016-17 at IFS sub centre Rewa (M.P.). The study reveals that the application of 100% NPK (N 120 kg, P2O5 60 kg and 40 kg K2O/ha) + 25 kg Zinc sulfate/ha based on soil test value for both crops gave rice yield 38.43q/ha and wheat yield 40.15 q/ha. The rate of increase in grain yield was 10.52% in rice and 17.98% in wheat as compared to conversion period. The integrated use of 50% NPK and 50% N through FYM gave maximum rice yield 38.09 q/ha and wheat yield 33.51 q/ha which were 36.09% and 21.93% higher than conversion period. Among different organic farming packages grain yield of rice and wheat was increased over conversion period. The organic carbon status has been found to increase under different organic sources of nutrient management as compared to initial status. Available potash status was found to decrease under different organic, inorganic and integrated nutrient management practices as compared to initial status.
