Impact of Green Manuring on Health of Low Fertility Calcareous Soils

This study was conducted in a rice-based cropping scheme to investigate the impact of green manuring on soil health, considering physicochemical properties and sustainable crop production. A field experiment started 2 November 2015 completed 15 April 2018 under rice–berseem (Trifolium alexandrinum) system calcareous soil. Two patterns, rice–wheat–sesbania (rostrata), were compared with commonly practiced rice–wheat (Oryza sativa-Triticumaestivum) pattern. Green berseem (last cutting) along 50, 75, 100% recommended fertilizer doses nitrogen, phosphorus, potassium (NPK) NPK fertilization control (no fertilizer). The plant growth parameters rice, including height, tillers per at maturity, yield data, recorded harvest. pre-sowing analysis revealed that experimental low salts, nutrient status very low. results indicated substantially enhanced grain straw rice crops. combined 75% produced highest (5.83 t ha−1 year III) other treatments. showed bulk density reduced while porosity, organic carbon, N, K, P contents significantly improved. From this study, it is conditions, regular use can improve growth, yield, and, therefore, should be adopted by farmers.
