Abstract
Sweet Potato Farming as Sources for Food Alternative and Carbohydrate Diversification.
Nani Zuraida and Yati Supriati. Food diversification is an urgent issue and its successful
application is very much expected to support the government program to fulfill the increasing national food due to the fast growth of people population. The lack of watershed supply due to the global climate and environmental changes had also called for the needs of food diversification. Sweet potato is an important crop, particularly as a carbohydrate source. The crop is easy to cultivate and its product is relatively cheap as an alternative food source beside rice. It can be grown on both dry land and irrigated land during the dry season. Besides, the crop also contained higher vitamins (A and C), and mineral (Ca) than rice. Swoet potato consumption pattern by people is still limited to alternative food or supplement traditional food. The sweet potato consumption per capita by the people is also relatively limited. This was due to the fact that food diversity is lacking, since sweet potato utilization as raw materials in food processing industry is not developed yet. In the other hand, yield of sweet potato can be significantly increased, from 9 t/ha to 15-20 t/ha, by growing on irrigated land in the dry season. The utilization of sweet potato as competitive carbohydrate source in food need to be promoted further.
