Sweet Potato Cultivar Trial

Sweet potato, Ipomoea batatas, is a warm-season vegetable crop that is widely grown throughout the world. In the United States, commercial production is mainly in the southern states. Many parts of the plant are edible, including leaves, roots, and vines. Tender leaves are a delicacy in a number of Asian and Southeast Asian countries. To grow successfully, sweet potatoes prefer both warm days and nights. Sweet potato plants require a long frost-free growing season to mature large, useful roots.

Effect of Plastic Mulch on Sweet Potato Yield and Quality

Sweet potato, Ipomoea batatas, is a warm-season vegetable predominantly grown in the southern part of the United States. In recent years, its production region has expanded quite rapidly to various Midwestern and Eastern states. Growing sweet potatoes in Iowa could be challenging especially due to the short growing season. The crop requires a long frost-free period and high soil and air temperatures to produce quality roots. Growing this crop on raised beds with plastic mulch could be an alternative technique as plastic mulch warms the soil and accelerates crop growth.
