Green manuring - A cost effective and farmer friendly alternative for farm yard manure

Long-term fertilizer experiments are an integral tool for comprehending how intensive cropping and continuous fertilizer application affect soil characteristics and crop performance. It paves the way for the evaluation of sustainable agriculture practices. The aim of the current study was to monitor how fertilizers and manures consistently affected the productivity of a rice-rice cropping system in a lateritic soil. In situ green manuring was identified as a practical and affordable technology. Integrated nutrient management with FYM and in situ green manuring with daincha (Sesbania) recorded higher grain and straw yields across years. In comparison to the plot receiving solely inorganic nutrients, the soil's organic carbon content and biological properties were higher in the 100% NPK+ FYM plot and the 100% NPK+ In situ green manured (daincha) plot. The economic analysis of the demonstrations in farmers field during 2019-22 indicates the cost effectiveness of the technology.
