Proceeding of A Symposium on Root Crop Yield Improvement, Processing and Utilization in Taiwan
Factors affecting the yield and quality of sweet potato can be classified into two groups; those factors originated from the nature include climate, soil productivety and fertility, and the prevalence of insects and diseases. Impacts from the human beings include varietal performance, cultural practices, and other measures such as capital investment and consumers¡¦ preference. The enhancement in yield and quality of any crop can be achieved by developing varieties capable of matching the environmental conditions under appropriate cultural practices. For sweet potato, major concerns related to cultural practices include the selection of high quality vine cuttings and the optimum decision in planting time, planting method, planting density, fertilization, irrigation, soil banking, and insect and disease management. Due to the shortage of farm labor, the development of mechanization, especially for planting and harvesting, is also essential to the successful production of sweet potato. In order to increase farmers’ profit, the adjustment of harvest time to meet market demand should be considered. Sweet potato is a better diet as compared to rice in terms of its higher nutritional value and dietary fiber content and lower calorie content. Studies are needed to expand its utilization and to develop modern processing techniques in order to facilitate the production of this important food crop.
