Two sunflower cultivars (Pioneer6480 and Poineer6431) were given four N applications (control, 50, 75 and 100 kg/ha). In both cultivars, N application increased leaf area per plant, plant height, floral disc diameter, number of seeds per floral disc, seed yield and dry stover yield significantly over check. Higher seed yield (23.77 q/ha) was obtained in highly fertilized (100 kg/ha) plots and minimum from check (19.64 q/ha). 1000-seed weight and seed lipid contents were not affected significantly. Both the cultivars gave similar seed yield and lipid content.
