Abstract
The present investigation was conducted during two consecutive year of 2019-20 and 2020-21 entitled effect of rice-based cropping system on available nutrient like N2o, P2o5 and K2o of soil under various nutrient management sources. The maximum available nutrient (273.95, 14.10, 296.86 kg ha-1NPK) was found in 100% organically based nutrient management practices than after 75% organic nutrient management followed by rest of treatments respectively. The available nutrient of soil was slightly changed by nutrient management practices, whereas available NPK was found not significant under rice-based cropping systems. During the research work, available nutrient gradually changed by initial status value but it was not significantly affected by rice-based cropping system.
