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. | Long term effect organic inorganic and integrated nutrient management on rice-wheat cropping system
