| Abstract | ||
| Afield experiment was conducted at the Experimental field of the Department of Field Crops ,Collage of Agriculture – University of Baghdad during 2009 - 2010 season . The aim was to study the effect of spraying Gibberellin ( 0 , 150 , 250 , 350 mg.L-1) and Ethephon ( 0, 100 , 200, 300 mg.L-1) on the yield and its component of rapseed (Brassica napus L.) . Fcatorial experiment in a andomized complte block design with three replication was conducted. The results showed that 250 mg.L-1 concentration of GA gave the highest Plant height 97.9cm ,number of branches per plant 69.5 branches.plant-1 and Oil percentage 44.42%. While the concentration of Gibberellins 350mg.L-1 gave the highest seed yield 2106 kg.ha-1 and highest number of capsules per plant 283.8, number of seeds per capsules 10.30 seed.capsule-1 and1000 seed weight 4.75 gm. The ethephon at concentration 100mg.L-1gave high seed yield 2175 kg.ha-1 respectively due to its significant affect on some yield components such as number of branches per plant and number of seeds per capsules . It was concluded that spray of canola with Gibberellin and ethephon effected on increasing yield and its components .Therefore it recomended to spray Rape with Gibberellin and ethephon to increase economic plant yield. | ||
