The study was conducted in five intensive Binamoog-8 (a mungbean variety developed by BINA) growing areas of Bangladesh, namely Pabna, Magura, Natore, Jessore and Rajshahi district to estimate the profitability and technical efficiency of the variety. A total of 200 farmers, 50 from each district were randomly selected as sample size for conducting the study. In the study, costs and return analysis were done on both cash cost and full cost basis for estimating profitability. The study found that the variety was profitable. The benefit cost ratio (BCR) was 1.87 and 2.95 on full cost and cash cost basis, respectively. The stochastic Cobb-Douglas production frontier model was used for estimating technical efficiency of Binamoog-8 producer in the study areas. The mean efficiency of the Binamoog-8 producers was 88.5%, which indicates that they were made a production loss of 11.5% due to inefficiency factors. Farmers faced some constraints in cultivating of the variety. Out of them the major constraints were lack of high-quality seed, disease and pest infestation, pod maturity in different times, high price of insecticides, lack of capital, lack of training and rainfall during germination period.
