This research evaluated the effects of gibberellin (GA3) and abscisic acid (ABA) on emergence capability, rate of emergence, vigor index and some physiological characters of chickpea seedling (Cicer arietinum L.) in a field experiment (as split) under dry and irrigated conditions. Seeds were primed with 0, 50, 100 and 150 ppm of each phytohormones. Examined chickpea cultivar was Azad. The results showed that emergence percentage, rate of emergence and number of lateral primary branches were the same in both irrigated and dry conditions. Root fresh and dry weights, seedling growth rate, shoot fresh weight and number of nitrogen fixing nodules increased by hydro-priming. Gibberellin priming improved stem height, root length and seed vigor. ABA priming resulted in maximum emergence percentage, rate of emergence and root dry weight in irrigated condition and the maximum root length and number of lateral shoot in dry condition. The most branchy roots observed in seedling which produced by non-primed seed. Vigor index was increased by 100 ppm GA3 in both irrigated and dry conditions.
