Background and Objective: In order to investigate the effect of foliar spraying of selenium on water use efficiency and some characteristics of savory (Satureja hortensis L.) under drought stress and partial root drying conditions, a factorial experiment was conducted based on a completely randomized design with three replications and based on pot culture in 2024 in the research greenhouse at University of Torbat-e Jam.
Methods: In this experiment, the treatments consisted of three levels of irrigation (full irrigation of 100% water requirement, deficit irrigation of 50% water requirement, and 50% partial root drying of water requirement) and foliar spraying of selenium factor in three levels (0, 5 and 15 mg/lit Na2SeO4). In this study, plant height, shoot and root dry weights, chlorophyll a, chlorophyll b, total chlorophyll, essential oil percentage, water use efficiency, relative water content and proline were measured.
Results: The results showed that the deficit irrigation (DI) led to a significant reduction in the measured traits of savory, except for water use efficiency. This reduction was greater at 50% DI than at 50% partial root drying (PRD). Therefore, applying the PRD method was found to be more appropriate than the DI method in this study. The results also showed that the application of DI and PRD increased water use efficiency by 54 and 73%, respectively. The results also indicated that foliar application of selenium increased the measured traits compared to the treatment without foliar application.
Conclusion: Considering the issues related to water scarcity, applying 50% partial root drying in savory can be recommended as a superior treatment and suitable approach to cope with the water crisis, moving towards a more sustainable agricultural system.
