This work aims to study effect of defferent levels of poultry fecal on oil coneentration and crop yield of sun flower under the irrigated conditions of Deirezzor governorate. The work was condicted in pots, where nitrogen and phosphorus were particularly studied as they have essential role in production and poultry fecal was studied as organic fertilizer which has small quantilies of N, P and K. The crop plant was studied at different growth stages. It was indicated that applying 32 t fecal / ha achieved the lighest increase in N and P ( dry matter) and the lowest value in the control. seed yield and dry matter increased with inceasing the levels of poultry fecal application. The treatment 8 t fecal /ha had the highest percent of protein as compared to control. It was shown that significant differences resulated from poultry fecal application as compared to control, and non-significant differencesresulting from applying the different levels. The treatment of 8 t fecal/ha had the highest net profit, where leaves content of phosphorus, seed yield and protenin percent were increased

Key words: poultry fecal, organic fertilizer, sun flower, seeds.

نفذ البحث في ظروف محافظة دير الزور خلال الموسمين الزراعيين 2008-2009 بهدف دراسة تأثير مستويات مختلفة من ذررق الدواجن في تركيز الزيت و كمية البروتين و إنتاجية محصول دوار الشمس في ظروف محافظة دير الزور . تم تنفيذ البحث بتصميم القطاعات العشوائية الكاملة و بثلاث مكررات لكل معاملة تم تجهيز التربة وإضافة الأسمدة الآزوتية و الفوسفاتية والبوتاسية اللازمة وبعد الزراعة تمت متابعة العمليات الزراعية وفي نهاية الموسم الزراعي تم اختيار خمس نباتات من كل مكرر من مکررات المعاملات المدروسة وأخذت القراءات اللازمة و المتعلقة بهدف البحثو بعد مناقشة النتائج توصلت للاستنتاجات التالية :
