Potassium is an essential nutrient that influences key processes in plants, including osmotic regulation, photosynthesis, and nitrogen assimilation. This study investigated the drought tolerance of wheat (Triticum spp.) plants treated with sufficient potassium (SK, 1 mM) low (LK, 0.05 under PEG-induced stress. Plant physiological development, canopy temperature, photosynthetic efficiency, antioxidant defense enzymes, assimilation enzymes were assessed. In non-drought conditions, LK increased temperature reduced dry matter yield performance, these effects becoming more pronounced SK-treated exhibited higher biomass, chlorophyll content, maximum quantum efficiency photosystem II, lower temperatures, even conditions.

Water scarcity emerges as a prominent threat to the vegetative and reproductive phases of cotton plants. However, water deficit stress induces reduction in stomatal conductance, altering interplay between plant nutrients, Irrigation productivity (IWP). The relationship IWP yield under irrigation remains unclear irrigated area Hyderabad, Sindh, Pakistan. experiment was conducted at experimental stations Agriculture Research Institute Tandojam two different sites during growing season 2022. design this study based on split-plot RCBD including five levels (control treatment (existing practice 75 mm irrigation−1), 20% drought existing irrigation, alternate (even), 30% irrigation) soil types. findings revealed significant differences moisture contents (SMCs) across all treatments, with notable height correlating increased stress. Despite variations types affecting number opened bolls, demonstrated decline, though not significantly certain treatments. Across levels, (even) could decrease by 6% reduce 5% compared control treatment. maximum recorded silt loam clay loam, respectively. validation calibration method CROPGROW-DSSAT model designed estimate IWP. substantial R2 value indicates strong concordance model-calibrated observed data, signifying model's ability simulate WUE strategies within specific regional climate conditions Hyderabad. Therefore, it is suggested that may maintain production while reducing usage,
