Abstract :This study was conducted to determine the fixed oil components and macro-micro nutrients of black cumin grown at different phosphorus doses. Seed samples were obtained from two different black cumin genotypes grown for two years (in 2017-18 and 2019-20 winter growing seasons) by applying five different phosphorus doses (0, 3, 6, 9, 12 kg da-1 P). According to the research results, increasing phosphorus amount did not show a significant difference in fixed oil components. Unsaturated fatty acid ratio has a much higher ratio than saturated fatty acid ratio. Linoleic acid (58.26%), an unsaturated fatty acid, and palmitic acid (11.84%), a saturated fatty acid, were found to be the highest in black cumin oil. When macro-micro nutrients are examined, it has been observed that the difference in dose and genotype x dose interaction is important. While the macro-micro elements Fe, Ca, P, Zn and Mn increased up to a certain dose, the elements Mg, K, Na, N increased depending on the dose increase, and the highest value was obtained from the 12 kg da-1 P application.
