This study aimed to investigate the effect of maternal environment on the vigor of the resulting seeds and their germination of chickpea. For this purpose, an experiment was conducted in Shahed University Research Laboratory in 2012-2022 as a factorial experiment to investigate the effect of irrigation regimes and sowing date on the quality of dragon's head seeds. Dragon's head seeds were obtained from maternal plants grown under two factors: an irrigation regime of 20% (complete irrigation, I20) and 40% (deficit irrigation, I40) depletion of available soil water; and Is (supplementary irrigation) based on a 20% depletion of available soil water in two stages, including the sowing and pre-flowering stage, as well as the autumn sowing (November 6) (S1) and spring sowing date (March 6).The abstract text should be in 12-point Times New Roman, single-spaced, and should not exceed 250 words. All manuscripts must be written in English, using 12-point Times New Roman font throughout. The results of the analysis of variance showed that the simple effects of sowing date and irrigation regimes on germination percentage, seed vigor index, seedling dry weight, and germination rate were significant. All germination-related traits increased under the I20 and I40 irrigation regimes in the autumn sowing date compared to the spring sowing date, respectively. In general, it seems that the I20 and I40 irrigation regimes can improve germination characteristics. Therefore, under drought stress conditions, the I40 irrigation regime under the autumn sowing date reduces the negative effects of drought stress on chickpea germination characteristics to some extent compared to the Is irrigation regime.
