Drought stress significantly impacts wheat productivity, but plant growth regulators may help mitigate these effects. This study examined the influence of gibberellic acid (GA3) and abscisic (ABA) on (Triticum aestivum L., CV: Giza 171) yield under different water regimes. Using a split-plot design, we tested three drought levels as main plots: normal irrigation (80% field capacity), moderate (60% severe (40% capacity). Subplots consisted GA3 ABA treatments at 100 200 ppm concentrations. Results showed that treatment enhanced multiple parameters irrigation, including height (25–30% increase), leaf area (30–35% reproductive traits increase in number spikes, 35% grains per spike). In contrast, resulted reduced (35% decrease) greater reduction vs. 20% control) conditions. also improved physiological catalase superoxide dismutase activities, protein content, proline accumulation. These findings demonstrate distinct roles regulating responses, providing valuable insights for management cultivation.
