Field experiments were inducted to compare differing proportions of broadcasting and side banding Nitrogen and Phosphorus fertilizer on sunflower (Helianthus annuus L) C.V. NK 212 during Kharif and Rabi season of 1987 and 1988 at National Agricultural Research Centre, Islamabad. Nitrogen and Phosphorus were applied at the rate of 90 kg and 60 kg P2O5/ha. Split application of fertilizer in equal doses side banded and broadcast at the time of planting resulted in the highest seed yield and in the largest head diameter of sunflower in both Spring seasons (1987 and 1988) as well as in the 1987 Kharif season. A significant increase in the 1000-seed weight was observed with split applications during the spring crop of both growing seasons. Plant height was not increased by split applications, with lowest heights to be associated with most side banding of fertilizers.
