This research was carried out to determine some important agronomical properties of sunflower varieties in Van (Eastern), a high latitude site, Turkey. During 2001-2002, some sunflower varieties (NSH-01, NSH-712, NSH-43, NSH-111, TR-6149 and 64A52) were sown as main crop in late May in 60 cm apart and thinned 15-20 day after emergence to a stand density of 55 000 plants/ha and given 120 and 100 kg ha-1 of N and P2O5, respectively under irrigated conditions. Data were tabulated on mean plant height, stem diameter, head diameter, seed number per head, 1000 seed weight, seed yield, oil content and oil yield for each cultivar in both years. It was showed that the all analyzed features were affected by cultivars and years. Averaged over years, seed yields ranged from 1.74 to 3.17 t ha-1 and oil yields ranged from 0.66 to 1.58 t ha-1. The TR-6149 cultivar had the highest seed yield (3.96 and 2.38 t ha-1, respectively) and oil content (49.83 and 50.20%, respectively) in both years. It was concluded that TR-6149, NSH-43 and NSH-111 were considered the best cultivars, having high oil and seed yields under irrigated conditions.
