Abstract:
The current study was conducted during the season (2021-2022 In the fields of al-Ghab Research Center in order to determine the effect of two different planting dates on the appearance of blight on the black cumin plant (Nigella sativa) and the plant’s susceptibility to the disease. The survey included (12) fields. The cultivation took place on two different dates (1-15 December and 1-15 February). The results confirmed the presence of significant differences between the two dates, where planting succeeded in the second date and the crop escaped from the threat of frost, which weakened the plant in the first date and made it vulnerable to infection. It will serve as a reference for scientists, researchers and agricultural workers to choose the most suitable date for planting the crop to escape the disease that has swept the crop in recent years and caused heavy damage and material losses. Note that references in this field are very rare.
key words: Nigella sativa, black seed , planting dates, blight disease.
