Maize is 3rd important cash crop of Pakistan after Triticum astivium and Oryza sativa. Cadmium is a heavy metal that affects various grain crops and gibberellic acid is a useful hormone against a variety of stress. To determine the effect of GA and Cd, a pot experiment was conducted in the OlD Botanical Garden University of Agriculture Faislabad. Two different maize varieties were used (Neelam and Desi makai). The concentrations of cadmium chloride (0 μM and 200 μM) and Gibberellic acid (0mg and 0.25 mg) were applied under CRD with three replications. Stress was applied after every 10 days and gibberellic acid was applied once in three leaves stage. After 60 days the plants were harvested. Different morphological parameters like fresh and dry root shoot weight, Root and shoot length, number of leaf, plant height and leaf area were recorded. All studied parameters were negatively affected by cadmium chloride while the foliar application of gibberellic acid improved these traits under cadmium chloride stress. Overall, Desi Makai performed better then Neelam in both stress and spray conditions.
