An ex-post rate of return analysis was considered to estimate the internal rate of return (IRR) to BARI - released improved varieties of mungbean that have been replaced the local varieties. The growth rate of area, production and yield before the release of mungbean varieties were 18.99, 20.85 and 1.86 %, respectively. After the release of improved varieties of mungbean, the area and production were increased dramatically but their growth rates were not satisfactory for various reasons, which should be studied. The internal rate of return to total investment in both mungbean research and extension was calculated at 34 %. It was found that in 1997-98, about 19% more mungbean production was made available because of the farmersþ adoption of the BARI - released mungbean varieties. The potential relative yield of BARI Mung-2 over the local varieties was found 43 % higher. The cost of production of high yielding varieties of mungbean was 49 % higher than the local varieties. Under various assumptions about the magnitude of the benefits and the research and extension expenditures, the IRR ranged between 18 and 50 %. This indicates that the funding of mungbean research and extension is a good investment.
