Oil contents and fatty acid composition of black cumin treated with some micronutrients (Fe (3 g Lit-1), Zn (2 g Lit-1), B (4 g Lit-1), and Mn (3 g Lit-1)) were determined. Oil contents of the plant seeds ranged from 31.64% (Mn) to 40.00% (Fe). Saturated fatty acids and unsaturated fatty acids ranged from 16.71%-17.54% and 80.86%-82.00%, respectively. The seed oils of all black cumin treated with fertilizers have high unsaturated fatty acid content as well as a balanced fatty acid composition. The major fatty acid in the oils was linoleic acid which ranged 56.85% (Zn)–58.85% (control). Oleic and palmitic acid contents of oils ranged from 22.80%–24.28% and 11.60%–11.77%, respectively. These results also suggest that these seed oils have a potential as a vegetable oil source for food industry.
