Abstract
A study was carried out at the Scientific Research Center of Erbil Polytechnic University in Erbil city during the fall of 2024. Three parameters were included in the experiment, which used a completely randomized design (CRD): zinc concentrations (0, 1, 2, and 3 g l⁻¹), seed soaking times (0, 6, 9, and 12 hours), and black seed varieties (Russian, Syrian, and Locally). In terms of germination percentage, germination speed, root length, shoot length, root and shoot dry weight, the Syrian variety treated with 2 g l⁻¹ zinc had the greatest results. Syrian seeds immersed for 12 hours produced the best outcomes, indicating a strong interaction between seed variety and soaking period. The best results were obtained after soaking with 2 g l⁻¹ zinc for 12 hours, according to the relationship between zinc concentration and soaking period. The Syrian variety produced the highest values for germination %, germination speed, root length, shoot length, and dry weights of both the root and the shoot after being soaked for 12 hours and treated with 2 g l⁻¹ zinc. However, the Russian variety treated with 2 g l⁻¹ zinc and immersed for 12 hours showed the highest fresh root and shoot weights. However, the Russian variety treated with 2 g l⁻¹ zinc and immersed for 12 hours showed the highest fresh root and shoot weights. It's interesting to note that the Syrian variety had the highest seedling value at 1 g l⁻¹ zinc with soaking duration (12 hours).
