A research about defining technologic and agricultural properties of sun seed species under non irrigable conditions

This research is conducted for the determination of the most suitable sunflower species in Manisa, Kemaliye region in 2008. Randomized complete blocks were designed with three replications. Fifteen sunflower cultivars were selected, and plant height, node number, head diameter, seed number per head, 1000 seeds weight total seed yield, total seed weight, crude oil % crude oil yields were observed and measured.As a result there were significant differences in crude oil yields between sunflower species that had been studied. The highest yield of crude oil was extracted from Armada (33,16 kg/da), and then followed by Meriç 2002(32,28 kg/da) varieties. The lowest crude oil quantity was extracted from Dk-F 2525 (10,70 kg/da).The highest seed yield was measured from Meriç-2002 (92,95 kg/da), followed by C-70165 (90,82 kg/da ).The lowest yield of seeds were obtained from Dk-F 2525 (34,16 kg/da ).
