Sweet potatoes are generally an easy crop to farm due to their low capital intensity and applicability on small tracts of land. There are two broad categories of sweet potatoes which are as follows: 1. The staple type with white flesh and white or purple skin with a high starch and dry matter content. 2. The desert flesh and orange skin with a high sugar and beta-carotene content. Commonly three distinct types of sweet potatoes are available for commercial production: 1. Orange/copper skin with orange flesh e.g. Beauregard, Hernandez, Beerwah Gold, NC-3, LO-323, Centennial, Darby and Jewel. Zimbabwean orange cultivators such as Beauregard have long, cylindrical to heavy elliptic tubers. They have high beta-carotene content and are fairly quick growers. It may become too big with long growing period. 2. White/cream skin with white/cream flesh colour, has a high yield and a good storage life. It can produce good yield in a relatively short growing period (4 months
