| Abstract | ||
| Field experiment was conducted during spring season in 2005 at two locations: AL-Hamdania and AL-Quba to study the effect of four plant population (33333 , 41700 , 55600 and 83333 plants ha-1),on growth, yield and quality of three sunflower cultivars (Coban , Peredovik and Iraqi flower), using randomized complete block design with three replication. The results showed that superiority of head diameter, no. of seeds / head, wt. of 1000 seeds, fertility percentage and linoleic acid percentage with 33333 plants ha-1, while plant population 55600 plants ha-1 was superior in seed and oil yield for both locations. Peredovik variety was significant for most studied characters except linolenic acid percentage. The interaction of 55600 plants ha-1 with Peredovik cultivar gave a higher value on seed and oil yield, which increased up to 3.25 and 1.49 ton ha-1 in AL-Hamdania and up to 3.21and 1.5 ton ha-1 in AL-Quba location respectively. | ||
