Peppers offer a viable option to tomatoes for commercial production in high tunnel greenhouses. In 2011 the Cornell Vegetable Program partnered with Harris Seed, Inc. to evaluate five varieties in a cooperating grower unheated high tunnel.

The peppers evaluated in 2011 performed very similar in total yield per plant as measured by pounds. When we look at fruit size and weight we do find differences that can help growers make choices in variety. When selling by the piece, in a retail setting, varieties such as Yellow Crest would work well. For wholesale accounts varieties such as Gordo will fill bushel boxes faster. Sandpiper, a slightly smaller fruit than the other bell peppers is this trial, gave very good yields and offers a nice color spectrum. High tunnels are a great tool for vegetable growers to increase quality and color of bell peppers. Total economic performance per square foot is much less than tomatoes. However, labor inputs are also lower. Although not a perfect rotational crop with tomatoes, peppers are not a host for Fulvia Leaf Mold, and are less likely to harbor Two Spotted Spider Mites. We encourage growers to consider peppers in high tunnels for increased quality and yield.
