Abstract

This study was conducted on a private farm in the Tour Sinai region of South Sinai Governorate during the 2022 and 2023 growing seasons. The research aimed to explore how different concentrations of copper chlorophyllin formula (Cu-Chl) (0, 0.5, and 1 g L^-1) affect the growth, productivity, and physiological traits of Spearmint (Mentha viridis) plant under three different irrigation intervals (every 2, 4, and 6 days).The findings revealed that extending the irrigation interval to 6 days, compared to watering every 2 days, significantly reduced plant growth parameters, including herb fresh weight per square meter, herb fresh yield per feddan, herb dry weight per square meter, herb dry yield per feddan, and volatile oil yield. But total chlorophyll, copper content, and proline content as well as the Water Use Efficiency (WUE) of the yield were increased under this treatment. However, the application of Cu-Chl notably improved all these traits compared to plants that did not receive Cu-Chl. The most effective treatment in this study was foliar spraying of plants with Cu-Chl at 1 g L^-1 combined with irrigation every 4 days. The study concluded that using Cu-Chl can overcome the negative effects of water deficit on the growth, yield, and physiological traits of Spearmint plant, as well as improve the Water Use Efficiency.
