Abstract

This paper is aims at studying the economics of scale of sweet potato cultivation. Sweet potato is one of the decreasing crop. Its cultivated areas has been decreasing more rapidly than soybean or corn. In this paper 23 farmers were surveyed, including 8 families with less than 1 ha, 7 families with 1-5 ha, and 8 families with more than 5 ha. The results are as follows; First, sweet potato cultivation is good for specialization, considering the high income per acre. Second, there is no good evidence explaining for the economy of scale of sweet potato cultivation, but there is an evidence for the profit of specialization. Large scale farmers have more incomes per acre, lather than more production or less management costs, by means of good sales methods. Third, mechanization of sweet potato cultivation is one of the key factor for successful large scale sweet potato cultivations.
