HDPS impact and policy implication of Special Project on Cotton

Though farmers earn a net income of ₹ 1,36,555/ha under HDPS, 78% more than ₹ 76,820/ha achieved under the conventional planting system, an increased expenditure of ₹15,475/ha will be a deterrent for the resource-constrained rainfed farmers to adopt HDPS without any funding support. Hence, it was felt necessary to establish a permanent Institutional mechanism to incentivize farmers for adopting HDPS. In this regard, NABARD has accepted ICAR-CICR’s cost estimates of HDPS cotton cultivation under rainfed conditions and the Public Sector Banks of Maharashtra have announced a scale of finance of ₹92,000/ha for HDPS cotton cultivation during kharif 2025, in addition to the existing scale of finance of ₹75,000/ha for rainfed cotton and ₹85,000/ha for irrigated cotton.

Stakeholder workshop as a part of the research project “Impact of Pradhan Mantri Fasal Bima Yojana on the socio-economic development of farmers: A study of select districts of Bihar and Maharashtra” funded by ICSSR and implemented by Dr. Sneha Kumari, Assistant Professor, Symbiosis School of Economics, Pune held on 28th December 2023 at Sakhar Sankul, Shivajinagar, Pune.
