Abstract:
A study was conducted to assess the long term effects of inorganic fertilizers and organic manures on physical properties and crop productivity after 31th cycle of rice-rice cropping system as 62th crop during kharif 2017 and 63th crop during Rabi-hot weather 2017-18 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) in Typic Haplusteps. The particle size distribution, textural class, bulk density, particle density and water holding capacity did not change significantly due to continuous application of inorganic fertilizers alone or organic manures plus inorganic fertilizers. Application of 50 per cent recommended NPK dose through fertilizers and 50 per cent N through FYM, paddy straw or glyricidia green leaf manuring (GGLM) during kharif season and 100 per cent recommended NPK dose through fertilizers during rabi season significantly reduced the bulk density and particle density while increased maximum water holding capacity of the soil. Long term application of Integrated Nutrient Management (INM) increase grain yield (25.07, 22.87 to 57.52, 57.87 q ha-1) and straw yield (30.65, 28.14 to 68.36, 67.94 q ha-1) in Kharif rice and Rabi-hot weather Rice respectively. Adoption of INM practices improved physical properties of soil alongwith yield under rice-rice cropping system in long run.
