Effects of organic fertilizers on yield and quality of black seed (Nigella sativa L.)

This study was conducted to determine the effects of organic fertilizers on the yield and quality of black cumin (Nigella sativa L.) in Eskişehir Osmangazi University, Faculty of Agriculture in 2021. The research was planned in a randomized block design with three replications. Çameli variety was used as plant material and bat manure, vermicompost and liquid organic fertilizers containing amino acids of animal origin were used as fertilizers. According to the results obtained in the research; plant height 26.63-32.87 cm, number of branches in the plant 3.18-3.58 pcs/plant, number of capsules in the plant 2.94-3.76 capsules/plant, number of seeds in the capsule 65.91-77.06 pcs/capsule, single plant seed weight 0.47-0.70 g/plant, thousand seed weight 2.82-2.93 g, seed yield 55.03-81.40 kg/ha, essential oil content 0.17-0.22% and essential oil yield 0.09-0.17 kg/ha. As a result of the research, it was seen that worm and bat fertilizers came to the fore in organic fertilizer applications. It has been shown that the organic fertilizers used in the study can be used as an alternative in conventional agriculture, where they have an important place in increasing the quality and yield.
