Selection and Storage Methods for Sweet Potato Seed Tubers
Timely harvest. If sweet potatoes are harvested too early, the yield is lower; if harvested too late, they are prone to frost damage, which affects storage. Therefore, it is generally best to begin harvesting when the temperature is around 18°C, and to finish harvesting when the temperature is above 10°C (that is, before the killing frost period). Generally, spring sweet potato fields used for slicing and drying are harvested first,
