Agriculture faces growing threats from climatic variability and severe water scarcity. As a drought-sensitive horticultural crop, potato (Solanum tuberosum L.) experiences marked declines in growth and tuber yield under moisture deficit conditions. Phytohormones serve as essential signalling molecules that modulate plant physiological responses under abiotic stress. The present study evaluated the protective efficacy of exogenous Salicylic Acid (SA) and Jasmonic Acid (JA) on potato cultivar (cv. Kufri Chipsona-1) subjected to water stress. Eighteen potted plants were arranged in a Completely Randomized Design (CRD), comprising control and water-stressed regimes combined with foliar applications of SA and JA across three replications. Exogenous SA application significantly enhanced plant height, chlorophyll retention, and overall tuber yield, thereby effectively mitigating drought-induced damage. Conversely, while JA mediated defense- elated responses, it demonstrated limited capacity for vegetative growth promotion under water-limited conditions.
