In ex-post rate of return analysis was conducted to estimate the economic impacts of saline tolerant rice varieties developed and released by the Bangladesh Institute of Nuclear Agriculture (BINA). The main objectives were to estimate: a) the aggregate economic benefits associated with BINA-developed saline-tolerant rice varieties and b) the productivity and profitability of saline-tolerant rice varieties by location and variety. An economic surplus approach was used in the analysis. There were two distinct parts: one was to calculate the research costs and the other part was to calculate the total benefits. The costs were calculated yearly from the beginning of the project in2005until2014. The benefits were calculated from the first year of release in year 2010until2025. The average per hectare BCR, net return, and yield were calculated as 1.71, $429and 4.84 tons, respectively. The estimated cumulative net present value (NPV) of benefits of adoption of the saline tolerant rice variety (discounted at 5%) were calculated as $220 million and the internal rate of return (IRR) of saline tolerant rice research and extension was estimated as 170 percent.
