High tunnel systems allow growers to provide markets with fresh, locally-grown products for a larger part of the year. During this presentation, research results will be shared on the utilization of high tunnels to maximize winter vegetable production. This project evaluated different cultural growing techniques, including planting date, black plastic mulch and row cover, for carrots, lettuce, spinach, and kale within a high tunnel at the Dixon Springs Agricultural Center in southern Illinois. Winter production can be a great avenue to diversify farm operations, increase income opportunities, and provide more local, Illinois-grown crops into the marketplace.
