Shadecloth was tested on tomatoes and chili peppers in Texas to see how it affected their growth and productivity. The study found that using 50% shade helped both plants by reducing heat stress and improving yield. However, using 70% shade actually decreased the yield of both crops. The plants grown in 50% shade had the best growth and highest photosynthetic rates, while those in full sun had the worst results. Overall, shading at 50% was the most beneficial for tomato and chili pepper production in Texas.
