Abstract

A field experiment was conducted during 2014-15 to investigate the Effect of integrated nutrient management (INM) on soil properties and performance of rice crop (Oryza sativa L.). The treatments were Control ( T1) , 50%NPK through inorganic fertilizer+50% N through FYM (T2), 50% NPK through inorganic fertilizer( T3), 75% NPK through inorganic fertilizer + 25 % N through FYM ( T4), 75% NPK through inorganic fertilizer( T5) and 100% NPK through inorganic fertilizer( T6). Application of 50%NPK through inorganic fertilizer+50% N through FYM recorded significantly higher organic carbon content, available N, P, K, S and soil physical properties as well as higher growth rate in terms of plant height, number of tillers and also yield as compared to other treatments. Effect of 50%NPK through inorganic fertilizer+50% N through FYM on availability of nutrients and growth and yield of rice was significantly superior. Integration of organic and inorganic fertilizers increased soil available nutrients (N, P, K and S) status in comparision to chemical fertilizer alone. Application of 2 50%NPK through inorganic fertilizer+50% N through FYM recorded significantly higher nutrients (N,P,K,S) uptake by crop as compared to other treatments.
