Chickpea production is low and unstable due to rainfed condition. Using priming and other per sowing treatments in many vegetables crops have improved seed performance. In order to evaluate the effect of hormo-priming on emergence, growth, physiological traits and yield of Chickpea under drought stress this study was conducted in two separate experiments. In the first experiment the effect of gibberellic acid on the emergence and vigor of chickpea (cultivar ILC 6266) were studied in glasshouse under drought stress. Gibberellic acid treatments, including concentration of zero, 50, 100 and 150 ppm. Levels of drought treatment were 70, 50 and 30 percent of field capacity. The second experiment was conducted in field. Drought stress levels were such as the first experiment. Gibberellic acid treatments, including concentration of zero and 150 ppm (best level of gibberellic acid in first experiment). Based on the results of this study in chickpea hormo-priming with gibberellic acid increased seed emergence and plant vigor in glasshouse conditions. Also Application of gibberellic acid resulted in improved of the growth and physiological traits in field condition but could not affected in seed yield. In this experiment drought stress caused a significant reduction in all characteristics. Priming greatly discomfit the destroyer effects of drought. Of course, this positive effect was more pronounced at higher levels of stress than the control condition. In this test 150 ppm gibberellic acid was the best priming level and in general with increasing concentration of priming, emergence and plant growth indicators also improved. We concluded that priming with appropriate concentration of gibberellin plays an important role in the induction of tolerance to drought and overcome limitations created by the environmental stress such as osmotic effects, ion toxicity and nutritional imbalance.
