Research Report: High tunnel eggplant varieties, pruning, and postharvest storage, 2018

Recently, parthenocarpic varieties of eggplant (ones that set fruit without pollination) have been developed specifically for greenhouse and tunnel production. In other parts of the world where greenhouse eggplant is more frequently grown, various pruning systems are used to enhance productivity and growth.

Our primary objective was to compare yields of eggplant varieties in high tunnel production conditions. We specifically chose to focus on elongated types and to include new parthenocarpic varieties selected for high tunnel and greenhouse conditions. We had two additional objectives: 1) to determine whether pruning to 2- or 4-leader systems would affect yields compared to no pruning, and 2) to compare quality of different varieties in post-harvest storage.

This report describes the results of our first year of experiments, conducted in 2018. Access the full report and all the details here.
