Effect of Plastic Mulch and Trellises on Cucumber Production in High Tunnels

Cucumbers (Cucumis sativus L.) are high yielding summer vegetables but are extremely frost-sensitive. Most vegetable growers in Iowa grow cucumbers and constantly explore ways to start the crop early in the spring. One method to extend the production season and start early production of cucumbers is using a high tunnel. A high tunnel helps protect plants from early season frost, warms the soil, increases ambient temperature, and enhances crop growth. High tunnel production is gaining popularity in the Midwest.

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.
