Effect of Different Organic and Inorganic Fertilizers on Growth, Yield and Quality of Black Cumin (Nigella sativa L.)

Black cumin is spices crop rich in nutrients such as protein, healthy fats (including omega-3 and omega-6 fatty acids), dietary fiber, and various vitamins and minerals. They are particularly high in thiamine (vitamin B1), niacin (vitamin B3), calcium, iron, and magnesium. The present investigation was carried out at the Central Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Rabi 2022 with a view to identify the effects of different doses of organic and inorganic fertilizers and its role in growth, yield and quality of Black Cumin variety AN-1. The experiment was laid in Randomized block design with 14 treatments and 3 replications with different combination in organic and inorganic fertilizers. Under this experiment, overall, 14 treatment was taken including control. According to the current research, the use of combination of organic manures and inorganic fertilizers had a significantly positive impact on the growth and development of black cumin. Among the various treatments that were evaluated, T7 (NPK 50% + Farmyard Manure 50%) yielded the most favourable results in terms of growth viz., plant height, number of flowers, capsules per plant, early flowering and maturation and yield viz., number of seeds per umbel, and seed yield per plant.
