Harvesting
Depending on grown variety, Sweet potato has the shortest growing cycle of the root crops and it is harvested at 4-5months after planting. In traditional farming systems, where the crop is mainly intended for consumption by subsistence farmers, harvesting may be spread over several months. The crop is lifted by hand; great care being taken to avoid damage to the tubers, with only the amount needed for immediate consumption being dug. If the crop is grown for sale or when there is a pronounced dry season, the whole crop may be harvested at once.
