Plastic Roof Materials as They Affect Bell Pepper Production in High Tunnels

ABSTRACTBecause of high humidity and precipitation, protected cultivation of bell pepper (Capsicum annum L.) is needed to produce high-quality colored peppers. The goal of the study was to compare light transmittance of shade cloth materials: Solarig (140 and 172), clear polyethylene, and clear polyethylene plus Aluminet O (22%, 30%, and 60% solar reduction, respectively) for red bell pepper production. Plant growth, leaf nutrient content, fruit quality, and marketable yield were not affected by treatment. Roof materials in Florida should be selected based on availability, durability, and cost rather than sunlight reduction within the ranges used in this study.
