Impact of shading techniques on the growth and yield of greenhouse-grown pepper plants

Abstract

This study evaluates the effects of different shading techniques on the growth, fruit quality, and yield of pepper plants (Capsicum spp.) cultivated in greenhouses. Considering the challenges posed by excessive solar radiation and high temperatures in greenhouse environments, this research aims to identify optimal shading strategies that can enhance plant performance and productivity. Three shading treatments-aluminized shade cloth, black shade cloth, and a control group without shading-were applied to pepper plants grown under greenhouse conditions. Growth parameters, including plant height, leaf area, and stem diameter, along with yield characteristics such as fruit weight, size, and number, were systematically recorded and analyzed. The findings suggest that specific shading techniques can significantly improve pepper plant growth and yield by mitigating stress conditions, offering valuable insights for sustainable greenhouse vegetable production.
