AbstractA field experiment was carried out during Spring season (2004) in Ishaqi Research Station Company For Industrial Products Ministry of Agricultural to study the effect of sulphur and phosphorus fertilizer levels on quality characters of sunflower hybrid Iraq flower. Split plot design with four replications was used Phosphorus levels were (0, 26, 52, 78, 104) P. h-1 as main plots whereas the sub plots were sulphur levels were (600, 1200, 1800, 2400, 3000) kg S/ h-1 sulphur levels were 2400 kg S/ h-1 gave the highest percentage of oil and protein (43.99 and 21.98) % respectively . Phosphorus also significantly influenced the characters above . The levels 104 and 78 kg P / h-1 showed the highest oil and protein percentage ( 43.40 and 21.96 ) % respectively . the interaction of 2400 kg S / h-1 + 104 kg P / h-1 was significantly influential , as it gave the highest oil and protein percentage (45.52 and 23.025) % respectively . Application of 1800 kg S / h-1 and 52 kg P / h-1 showed the highest percentage of oil and protein (2.474 , 2.820 ; 1.276 and 1.422 ) t / h respectively .The interaction between the two factors influenced the yield of oil and protein significantly. The interaction of 2400 kg S / h-1 + 52 kg P / h-1 gave the highest yield oil (2.954) t / h and the interaction of 1200 kg S / h-1 + 52 kg P/ h-1 gave the highs yield protein (1.487) t/ h .
