An experiment was undertaken to study the effects of planting dates and nitrogen fertilizer application on growth, yield and oil contents of sunflower at the Agronomic Research Area, University of Agriculture, Faisalabad during 1999. Two sowing dates i.e. 10 and 30 August were compared with five nitrogen levels viz. 0, 50, 100, 150 and 200 kg N ha-1. Results on growth and yield (i.e. leaf area per plant, plant height, head diameter, number of filled achenes per head, 1000-achene weight, biological and achene yields) were reported significantly higher in the crops sown earlier on 10 August with the treatment 150 kg N ha-1 and lower yield was attributed in case of late sowing crops on 30 August.
