A total of 64 “Jewel” sweet potato green samples collected at the end of the growing season, were analyzed to determine and compare the effects of multiple topping on dry matter, calcium, iron and zinc contents of “younger” 4‐inch leaf and stem‐petiole tips with “older” 4‐inch portions of the same material. Older material contained the highest concentration of the minerals, and the concentration in both “young” and “old” plant material wasunaffected by yearly planting. When the mineral content was compared to the Recommended Daily Dietary Allowance for adults it was relatively good.
