Decisions regarding when to harvest and when to sell sweet potatoes are more complex than for other crops because yields continue to increase after the crop is initially ready for harvest, and sweet potatoes can either be sold at harvest or cured and stored for later sale. The optimum marketing decision, based on expected net revenue, is dependent on yield and prices and their variability, and on costs of storage. A marketing strategy is developed using Target MOTAD and data covering 21 years.
