Abstract
The economic impact of the KRH-4 paddy hybrid, developed by the University of Agricultural Sciences, Bangalore, was evaluated in the Southern Dry Zone of Karnataka. The Economic Surplus Model and Total Factor Productivity were employed to assess productivity and economic returns. The KRH-4 paddy generated a total economic surplus of ?65.45 crores during 2012–2020. A significant share (90.7 per cent) of the surplus accrued to consumers, while producers received only 9.3 per cent, indicating a marked disparity due to non-remunerative market prices for paddy. The Net Present Value of research benefits, discounted at 7 per cent, was estimated at ?25.97 crores, with an Internal Rate of Return (IRR) of 59 per cent, reflecting robust returns on research investment. The number of processing mills and the nitrogen-to-phosphorus ratio had a significant positive impact on productivity. These findings underscored the importance of policy measures to improve productivity.
