“…In the current study, the growth characteristics of cotton plants grown under drought conditions decreased compared to those of plants grown under normal conditions (Table 2). This reduction in the growth might be due to a decrease in cell elongation caused by the inhibiting impact of WD on growth-stimulating hormones which, in turn, lead to reduce in cell turgor, volume, and eventually growth (Mahdi et al, 2017). However, foliar-applied SA may help reduce the injurious effects of WD and increased the growth traits of water-stressed cotton plants.…”

“…However, it is necessary to increase the water stress tolerance of field crops in order to improve their productivity with finite water supply. More attention has recently been paid to safe and natural antioxidants such as proline, salicylic acid and α-tocopherol and Mahdi et al, 2017 which have the ability to inhibit the free radicals and therefore raise plant resistance to an abiotic stresses.…”

Water deficit (WD) is the major abiotic factor negatively impacts crop productivity around the world. Since, salicylic acid (SA) is one of antioxidant that plays vital role in stimulating plants to drought-tolerance. A field experiment in 2018 and 2019 seasons was conducted to test the impact of foliar applied SA at various concentrations (without spray as control, 1.0 mM and 1.5 mM) on growth, yield, fiber properties, physiological attributes, plant water relations, nutrients, and water use efficiency (WUE) in cotton plants grown under two regimes of irrigation (irrigated every 14 days as normal irrigation and irrigated every 21 days as water stress). Results revealed that foliar spraying with SA enhances WD tolerance in cotton plants by improving physiological attributes, nutrients and tissue water status by increase membrane stability index (MSI) and relative water content (RWC), and decrease electrolyte leakage (EL). These results were positively reflected in enhancing plant growth, yield, fiber properties and WUE under water stress conditions. Therefore, SA could be a hopeful material to mitigate the harmful effects of WD and reduce the number of irrigations in Egyptian cotton.
