The utilization of Nigella sativa L., commonly known as black cumin, in traditional and medicinal practices is well-documented, attributing to its wide-ranging biological activities. Given its significance, this study explores the efficacy of various seed priming treatments (control, distilled water, potassium humate, and gibberellic acid) under laboratory and field conditions to enhance the early growth stages of Nigella sativa L. Priming treatments aimed to improve germination rates, plant height, and other growth parameters, potentially translating into increased agricultural productivity. According to results plant height ranged from 52.38 to 58.91 cm, number of branches between 3.76 and 3.98 (branch plant-1). The number of capsules varied from 4.93 to 6.81 (capsule plant-1), capsule seed weight was between 0.19 and 0.22 (gram capsule-1 ), and the thousand-seed weight ranged from 2.26 to 2.39 grams. The germination rate ranged from 78% to 93%, germination index 4.22-5.83 and mean germination time was observed from 4.27 to 4.82 days. Our findings reveal significant effects of priming on germination parameters and plant height, this offering insights into the potential of these treatments to optimize crop growth. However, the transition of these benefits to field conditions, particularly yield-related parameters, appeared limited, suggesting the complex nature of growth enhancement strategies and their implications for agricultural practices.
