INTRODUCTION
Sweet potatoes may be harvested whenever they reach a marketable size. Under good growing conditions, harvesting may begin 90 to 100 days after planting of some varieties and continue until well after frost has killed the vines and leaves. Injuries to the roots detract from their value and cause losses. Injury to sweet potatoes can be incurred several ways that will impair their keeping quality.
