Project Summary

This project has three broad objectives to increase the size, profitability, and long-term viability of the controlled environment agriculture industry: 1) to increase high value controlled environment food production, 2) to reduce inputs in greenhouse food and ornamental production (and outdoor ornamental production), and 3) to increase our understanding of how high temperature affects yield/growth to accelerate breeding/development of high temperature tolerant plants/cultivars. These objectives create economic opportunity for Minnesotans and those in the Upper Midwest, and increase food safety and accessibility, and decrease the inputs required for these crops and the negative environmental impacts.
