OFRF Farmer Led Trials: Shade Cloth for Pepper Seed Production
Lindsay Klaunig, Trouvaille Farm

Farm Trial Overview
Lindsay Klaunig is the owner/operator of Trouvaille farm, located in the hills of Southeastern Ohio. With 20 years of growing experience, she produces a range of open-pollinated vegetable varieties that are being grown as seed crops, to be sold through small regional seed companies, along with a diversity of heirloom crops grown for local and regional markets.
As a seed grower, it is important to Lindsay to have access to varieties that are regionally-adapted and able to thrive in low-input systems. She sees the opportunity of open-pollinated seed varieties as a vital tool as the climate changes and modern hybrids may not have the same capacity to thrive in severe weather events. In recent years, the extremes of heat and drought have been a major challenge for many of her long season summer crops, like tomatillos and peppers.
Lindsay was interested in trying shade cloth on her peppers, but wasn’t sure if it would have a negative effect on fruit set or seed production. Lindsay thought that shade cloth may help certain crops produce more flowers, fruit, and seed in the heat of the summer. Since Lindsay grows many pepper varieties and their seed value is relatively high, she wanted to find out if using shade cloth would improve fruit set in pepper plants grown for seed? And how would that impact fruit yield, seed yield and seed quality (germination)?

Key Findings
- Total fruit yield was significantly higher in non-shaded plots, seed yield per bed foot was also higher in non-shaded plots, indicating that the black shade cloth reduced yield.
- The season that this trial took place was one of the warmest and driest on record. The use of black shade cloth may have increased the temperature rather than provide any shade relief, as intended.
- In the future, Lindsay would like to try white shade cloth, and be sure to use larger hoops to allow space for more airflow over bushier crops like peppers.
