| Abstract | ||
| The experiment has been conducted during winter season 2007-2008 in Sammawah province – south of Iraq . Nitrogen has been applied at the rates of ( 0 , 60 , 70 and 80 kg Urea / ha ) , while phosphate levels are (0 , 100 , 110 and 120 kg Triple Super phosphate TSP /ha ) . The experiment is laid out in RCBD with 3 replications . Data have been collected on plant height (cm) , stem diameter . No . of branches .No. of capsules per plant .No. of seed per capsules , 500 seed weight , seed yield per plant (gm) . seed yield (kg l ha) % fixed oil rate and fixed oil yield (kg / ha ). Significant differences are reveable between the nitrogen and phosphorus fertilization . The best result were obtained when using the combined application of 70 kg Urea / ha with 110kg TSP/ha. | ||
