High tunnels are being used by specialty crop producers to enhance production yields and quality, extend growing seasons, and protect crops from extreme weather. The tunnels are unheated, plastic-covered structures under which crops are planted directly in the soil, and they provide greater environmental protection and control than open-ield production. This study uses ield-level experiments to evaluate high-tunnel production. The results suggest that investments in high tunnels can provide increased pro its and superior protection against adverse risks relative to crop insurance.
