Cost-effectiveness and Resource Use Efficiency of Sweet Potato in Bangladesh
In Bangladesh sweet potato is the 4th most important source of carbohydrate after rice, wheat and potato. The study was conducted to determine the profitability and resources use efficiency of sweet potato (Ipomoea batatas Poir) in Bangladesh. This study also aimed to find the factors affecting gross return of sweet potato production. A total of 100 farmers were selected from the study area through stratified random sampling technique and face to face interview was conducted to collect primary data. The cost and return analysis indicated that per hectare net return from sweet potato was 82,758.93 BDT (Bangladesh Taka). Benefit cost ratio (BCR) was found 1.97. Labor and vine cost accounted for the 48% and 28% of the total cost, respectively. Cobb-Douglas production function was used to determine the factors affecting gross return of sweet potato. The result showed that farm size, cost of vine, cost of land preparation and cost of labor have positive impact on gross return. Sweet potato cultivation is more sensitive to the output price which can be compensated by increasing yield. Resource use efficiency analysis revealed that farmers are not efficient in using resources in sweet potato production. Vine, land preparation, fertilizer and labor were underused and therefore increase the use of these resources can maximize profit in sweet potato production in Bangladesh.
