Abstract
A field experiment has been implemented during spring season of 2011 in the AL-Qassim district 30 km. south of Babylon province to study the effect of various treatments of organic, chemical and biological fertilizers in growth and yield of sunflower for flammee category. The experiment has included eight different fertilizing treatments (T0 control , T1 chemical fertilizers , T2 organic fertilizers , T3 bio- fertile EM1 , T4 chemical + organic + EM1 fertilizers ,T5 chemical + organic fertilizers , T6 chemical fertilizer + EM1 , T7 organic fertilizers + EM1). The results showed of recording the highest rates for studied traits in fertilizing treatment (T5) with morale difference on control treatment and other treatments but they gave the lowest rate for ratio of oil in seeds (37.27%) while the control treatment give the highest rate for this characteristic (44.50%) . fertilizer treatment (T5) had superiority by giving the highest rate for seeds yield and oil yield , it become 4.316 t/h and 1.609 t/h in sequence and that compensates the lack in oil rate in the seeds of sunflower . the results had also showed that treatments added to them them the bio-fertile (EM1) ,its performance was better than treatments that not dealt with that fertile in the category of leaf area and number of seeds in the head and plant yield (gm.), seeds yield(t/h) and oil yield (t/h).
