Abstract:
This research was carried out to determine some important agronomical properties of the black cumin in Van, Turkey. The experiments were designed in a Randomized Complete Block Design with three replications. In the study, four different seed rates 5, 10, 15 and 20 kg ha-1 were applied. The seeds were sown as main crop in 3 April and 10 May in 2001 and 2002, respectively in 25 cm apart and given 30 and 60 kg ha-1 of N and P2O5, respectively. Data were tabulated on mean plant height, the number of branch, the number of umbrella, the number of seeds in the umbrella, thousand-seed weight, seed yield (kg ha-1), essential oil content (%) and essential oil yield (kg ha-1) in both years. It was showed that the analyzed features were generally affected by seed rate applications. Averaged over years, the highest seed yield 701.2 kg ha-1 and essential oil yield 3.5 kg ha-1 obtained from the 15 kg ha-1 seed rate application. It was concluded that the 15 kg ha-1 application were considered the optimum seed rate, having high essential oil and seed yield in the black cumin.
