Abstract:
Nutrient management in French bean has been a major concern under organic farming systems. Therefore, to determine the most effective compost sources for organic French bean cultivation, promoting sustainable agriculture, enhancing crop yield, and ensuring economic viability for farmers while reducing the environmental impact of farming, the present investigation was carried out in rabi season of 2020-2021 at certified organic field of College of Agriculture, Pune with ten treatment combinations including various levels of FYM, mushroom compost and vermicompost and replicated thrice. Assessment of various growth parameters, yield attributes and economics was carried out. The results showed that the treatment of 125% RDN through vermicompost resulted in longer vegetative stages, higher nodulation and dry matter of plant. It also resulted in higher yield attributes and seed yield (14.93 q ha^-1) as compared to all other treatments. The application of 125% RDN through vermicompost gave the maximum gross monetary returns (Rs 149591 ha^-1) and net returns (Rs 75431 ha^-1) than all other compost sources but maximum B:C ratio (2.30) was obtained in 100% RDN through mushroom compost. Thus, the farmers can adopt the application of 125% RDN through vermicompost to get the maximum net returns under organic French bean cultivation.
