Sunflower is an important oilseed crop which ranks third in the world next to soyabean and groundnut. The productivity of sunflower can be increased with judicious use of inputs under higher plant population levels. Split application of N has been reported to favourably influence the nutrient uptake, growth, yield characters and seed yield of sunflower. In general, growth and dry matter accumulation in sunflower are higher at increased N and population levels.
