The Effect of Growing Sweet Pepper under Shading Nets in Dry Subtropical Conditions on Yield and Fruit Quality Indicators

This article presents the results of a study on the effectiveness of growing sweet pepper varieties under shading nets in the dry subtropical conditions of Uzbekistan. The study evaluated important economically and biologically relevant traits of the Nargiza, Tong, and Dar Tashkenta varieties grown in open-field conditions and under shading nets, including fruit weight, length, diameter, wall thickness, total yield, and marketable yield. The results showed that growing sweet pepper under shading nets increased fruit weight and size, fruit wall thickness, and yield parameters in all studied varieties. Under shading nets, fruit weight increased by 18.4 g in the Nargiza variety, by 16.0 g in the Tong variety, and by 18.0 g in the Dar Tashkenta variety. Total yield increased by 6.9 t/ha, 7.5 t/ha, and 5.8 t/ha, respectively. The marketability of the yield increased by 20.0–28.0% across the varieties, reaching 94.6–95.5%. The results demonstrate that the use of shading nets in sweet pepper cultivation contributes to increased yield and improved quality of the resulting produce.
