In Uganda, sweet potato (SP) on-farm production has at least tripled as a result of many (93% in 3 sampled districts) farmers adopting improved varieties. The major bottleneck now is low market prices and hence low income for the farmers. Farmers are risk-averse and will not produce more SP for a commercial outlet without a guaranteed market. Efforts now are geared to linking SP farmers to markets hence this study of simulating sea freighting of SP under controlled temperature and relative humidity conditions. The objectives of the study were two-fold, to assess the performance of sweet potato under simulated sea freight conditions and give an estimated cost of sea freighting sweet potato.
