This study was carried out Ege University Faculty of Agriculture Field Crops Department in the experimental area during the 2021-22 vegetation period. In this study, it was aimed to determine the yield and yield components, oil ratio and oil composition of the black cumin plant of organomineral and compound fertilizers. Cameli black cumin seeds were used as research material. Control, 4:11, 11:21:5, 18:46:0, 20:20:0 and 15:15:15 fertilizers were applied in the experiment. Emergence time (days), flowering time (days), growing time (days), plant height (cm), total number of branches (pieces plant^-1), total number of capsules (pieces plant^-1), thousand grain weight (g), seeds yield (kg da^-1), biological yield (kg da^-1), harvest index (%), oil yield (kg da^-1), oil ratio (%) and oil components (%) were investigated. According to the results obtained, it was determined that the emergence period of the seeds varied between 15-18 days and the vegetation period between 118-129 days. In terms of applied fertilizers, it was determined that the plant height varied between 63.0-72.3 cm and the total number of capsules varied between 6.0-8.8 pieces plant^-1. In terms of seed yield, the highest 85.48 kg da^-1 was found in 20:20:0 inorganic compound fertilizer. Among the organomineral fertilizers, 4:11 fertilizer reached a higher yield value than 11:21:5 fertilizer. The oil yield varied between 20.9-26.0 kg da^-1. In terms of organomineral and compound fertilizers, the highest oil ratio was determined from 20:20:0 with 32.1% and 11:21:5 with 31.2%. In terms of applied organomineral and inorganic composite fertilizers, linoleic acid was the most followed by oleic and palmitic acids, respectively, in fatty acid composition, and their proportional distribution was determined as 22.79%-23.93%, 52.77-54.69%, 12.56-13.41%.
