The study was conducted in seven agricultural regions of Bangladesh to compare the profitability of BINA developed mutant rice variety Binadhan-7 growers and non-growers by location. The objectives were: i) to determine the profitability of mutant rice growers and non growers; ii) to assess the impact of Binadhan-7 production on livelihood pattern of the growers and iii) to identify the preferences and constraints of the variety cultivation. A total of 280 farmers were randomly selected to fulfill the objectives. A pre-designed interview schedule was used to collect the necessary data. Descriptive statistics, profit function and livelihood assets were used to analyzed the collected data. The study revealed that total variable cost of rice cultivation was BDT. 46408.22 & BDT. 48382.22 for mutant & non mutant, respectively, per hectare which was 76% of total cost of production (Table 1.). On an average, the total cost of production was BDT. 63772.5 per hectare, where 24% was fixed costs and 76% was variable cost. For Binadhan-7 cultivation per hectare average net return were found in the highest in Dinajpur BDT. 70918.66 and the lowest in Jashore BDT. 33703.45. BCR on total cost basis was found 1.87 which was the highest in Sylhet 2.56 and the lowest in 1.51 in Jashore for Binadhan-7 production. In case of non growers BCR on total cost basis was found 1.40 which was lower than Binadhan-7 production in the study areas indicating Binadhan-7 growers earn much than the non growers. The asset pentagon approach showed that there is a noteworthy improvement based on different capitals (namely, human capital, social capital, natural capital, physical capital and financial capital) of farm households adopting mutant rice variety in comparison to nonmutant variety. Increases in capitals of sampled farm households were the highest for financial capital that was 10.60 % and the lowest was for natural capital i. e 2.79%.Among the preferences and constraints of the variety cultivation the highest preferences was 96.43% for short duration and it was ranked I, the lowest was high yielding i.e 84.29% which was ranked as V. Among the constraints, the highest constraint reported by the farmer was labour crisis as well as high price of labour (75.71%) and it was ranked I and the lowest ranked V was marketing problem including low price of paddy, high transportation cost, market distance i.e. 53.57 % in Binadhan-7 cultivation.
