abstract
Sericulture, an important agro-based rural enterprise in India, particularly in Karnataka, not only supports livelihoods but also generates significant organic waste such as leaf litter, silkworm litter, pierced cocoons and rearing bed residues. If left unmanaged, this waste poses environmental and health challenges; however, it holds potential for conversion into valuable products like compost, contributing to sustainable agriculture and improved farm economics. This study was conducted to assess the economics of efficient waste management in moriculture and sericulture through composting, with primary data collected from 30 farmers in Maddur and Malavalli taluks of Mandya district, Karnataka. Using the enterprise budgeting technique, the study estimated costs and returns associated with composting sericulture waste. Results showed that the average total cost incurred per acre per year was Rs. 25,472.20, of which variable costs dominated at Rs. 24,692.20, primarily due to human labour and cow dung inputs. The process yielded 19.55 tonnes of compost annually, generating gross returns of Rs. 36,167.50 and net returns of Rs. 10,695.30 per acre per year. The findings demonstrate that composting is economically viable and enhances income while reducing reliance on chemical fertilizers and improving soil fertility. The study supports the hypothesis that efficient waste management in sericulture can transform a disposal problem into a revenue-generating opportunity. With proper extension support, training and policy incentives, composting can play a strategic role in promoting sustainable practices and inclusive growth in the sericulture sector.
