Abstract Climate change‐induced drought stress (DS) poses a significant threat to crop production, emphasizing the need for innovative strategies mitigate its adverse effects. Prior studies have demonstrated distinct capacities of salicylic acid (SA) and sodium hydrosulfide (NaHS) augment plant resilience against drought‐related stressors. However, little is known about how they work together or specific processes by which increase DS tolerance. The purpose this research was determine SA NaHS affected performance wheat plants during growing seasons 2021–2022 2022–2023, when there drought. employed block‐randomized experimental layout with split plots, where primary factors included two irrigation levels: full (IW1, 100% water requirement) deficit (IW2, 50% requirement). Secondary application mock control, 0.5 mM SA, 0.3 NaHS, an H 2 S donor, either individually in combination, administered before onset DS. their combination significantly enhanced resistance Significant increases number physiological markers, including proline content, relative content (RWC), Fv/Fm, chlorophyll antioxidant enzyme activity, improvement. Furthermore, drought‐stressed plants, treatments decreased amounts hydrogen peroxide (H O ), malondialdehyde (MDA) electrolyte leakage (EL). In conclusion, our study highlights possibility whether applied improve presenting viable approach lessen effects climate change on agricultural yield.
