Field experiment was carried out during summer and South West Monsoon seasons of 1997 at Tamil Nadu Agricultural University Farm, Coimbatore to study the effect of NPK levels and seed setting treatments on nutrient uptake and quality of sunflower var. Co4. Among NPK levels, N:PK at 80:40:40 kg ha recorded higher seed yield and nutrient uptake. With respect to seed setting treatments, 0.2 per cent borax +2 per cent DAP spraying at ray floret opening stage improved the seed setting percentage. NPK levels significantly influenced the quality parameter, crude protein content. Among NPK levels, N:P:K at 80:40:40 kg ha recorded higher crude protein contents in both the seasons. The seed setting treatment failed to exert any significant influence on crude protein and oil content
