Background and Objective: In order to investigate the effect of foliar spraying of selenium on water use efficiency and some characteristics of Satureja hortensis L under drought stress and partial root drying conditions, a factorial experiment was conducted based on a completely randomized design with 3 replications and based on pot culture in 2024 in the experimental research greenhouse at university of Torbat-e Jam.
Methods: In this experiment, the treatments consisted of 3 levels of irrigation (100, 50% Deficit Irrigation and 50% partial root drying of water requirement) and foliar spraying of selenium factor in three levels (0, 5 and 15 mg/lit Na2SeO4).
Results: The results showed deficit irrigation led to significant reduction some characteristics compared to the control treatment (100 percent water requirement). This reduction was greater in deficit irrigation (DI) relative to partial root drying (PRD). Also, the results showed by applying 50% deficit irrigation (DI) and 50% partial root drying (PRD), water use efficiency increased by 55 and 73 respectively. Also, the results showed that foliar spraying of selenium led to an increase in the measured factor compared to the absence of foliar application. Based on the results of this research, applying the partial root drying (PRD) method was found to be a more suitable method than the deficit irrigation (DI) method in terms of negative impact on plant traits and increasing water use efficiency.
Conclusion: Therefore, considering the issues related to water scarcity, applying 50% partial root drying (PRD) in Satureja hortensis L can be recommended as a superior treatment and suitable approach to cope with the water crisis, moving towards a more sustainable agricultural system.
