Abstract

Abstract Growth of ‘Jewel’ sweet potato [ Ipomoea batatas (L.) Lam.] plants was increased significantly by black plastic mulch. Leaf area, number of leaves, and total shoot dry weight were significantly larger for mulched than for unmulched plants. Marketable root yield was increased significantly by black plastic mulch and raised beds. The highest root yield (18.6 MT/ha) was obtained from mulch-covered raised beds.
