In order to investigate the effect of priming of seeds of different black cumin ecotypes with humic acid and biozinc on quantitative and qualitative traits, a factorial experiment based on a randomized complete block design (RCBD) in three replications in the research farm of Golestan Agriculture and Natural Resources Research and Education Center during 2022-2023 growing season. The priming used included control (no priming), humic acid (containing 12% humic acid, 2% fulvic acid, 4% soluble potassium) and biozinc (containing 14% soluble zinc, 8% soluble sulfur) and three black cumin ecotypes (Indian, Syrian and Iranian) that were treated before planting. Maximum and minimum plant height (85.57 and 42.90 cm), root length (12.17 and 9.57 cm), height of the first branch of the plant (56.83 and 13.17 cm) and seed yield (163.53 and 71.43 gr.m2) were related to the Indian ecotypes primed with biozinc and the Iranian ecotypes without priming, respectively. However, the maximum percentage of oil, total phenol, total flavonoid and percentage of free radical activity (31.77%, 24.2 mg.g-1, 9.9 mg.g-1, and 70.05%, respectively) related to priming Iranian ecotypes with Biozinc priming. seed priming with humic acid and biozinc had a great effect on many quantitative traits. So that if the goal of cultivation is to achieve high grain yield, priming Indian ecotypes should be used; But if the goal is to achieve the highest percentage of oil, it is appropriate to use primed Iranian ecotypes.
