Long Term Effect of INM on Yield and Nutrient Uptake of Rice-Rice Cropping System in North Konkan

Present investigation is a part of long term experiment which was started in 1986 87 at Model Agronomic Experimental Farm, Regional Agricultural Research Station, Karjat, Dist. Raigad, Maharashtra 18.920 N latitude, 73.330 E longitude and 52.0 m altitude on yield and uptake of nutrients in rice rice cropping system. For present investigation 31thcycle rice crop was grown as 62th crop during kharif and 63th crop during Rabi hot weather. Long term application of Integrated Nutrient Management INM increase grain yield 25.07, 22.87 to 57.52, 57.87q ha 1 and straw yield 30.65, 28.14 to68.36, 67.94q ha 1 in Kharifrice and Rabi hot weather Rice respectively. Higher rice grain yields were observed in T6 receiving50 per cent RDF 50 per cent RDN through FYM to Kharif rice and 100 per cent RDF through inorganic fertilizers during Rabi , while least was obtained in control during both kharif season and Rabi season. The uptake pattern of nutrients in both of the rice variety Palghr 1 during Kharif and KJT 3 in Rabi season followed the same trend. Adoption of INM practices saved 50 per cent of recommended dose of nitrogen with incorporation of FYM as organic source of nutrient in rice rice cropping system in long run. S. S. Bhosale | D. G.
