| Two field experiments were conduct out on field of field crop department/ college of agriculture-university of Baghdad in winter season of 2008/2009 to investigate the response of caraway to spray the extracts of Roselle and senna vitamin complex using some growth and yield traits arranged in factorial experiment system applied with RCBD with three replicates. The first factor included the two extracts and the second one was the vitamins complex. Results revealed that without complex was superior in branch no., dry weight, umbellet no., umbel no., fruit yield, volatile oil% and volatile oil yield of 11.00 branch.plant-1, 70.00 cm, 15.50umbellet.umbel-1, 46.50 umbel.plant-1, 589.95 kg.ha-1, 1.75% and 8.77 L.ha-1, respectively, for Iraqi cv. While in Egyptian cv.(balady), vitamins complex gave the highest means of branch no., plant height, dry weight, umbel no., fruit yield, volatile oil% and volatile oil yield of 10.83 branch.plant-1, 90.31cm, 49.45 gm.plant-1, 43.50umbel.plant-1, 346.85kg.ha-1, 2.35% and 7.42L.ha-1, respectively. Results also showed that roselle extract gave the highest means of dry weight (58.00 and 48.24gm.plant-1), fruit no. (11.39 fruit.umbellet-1,for Iraqi cv.) and umbel no. (40.90 and 42.80umbel.plant-1), for each cvs, respectively. While senna was superior in fruit yield (494.90 and 283.70 kg.ha-1), volatile oil% (2.04%, for balady cv.) and volatile oil yield (7.67 and 6.11L.ha-1), for each cvs, respectively. It could be concluded that the Iraqi cv.didn't respond to vitamins complex application. While the Egyptian (balady) clearly responded because it growth and yield traits were improved. The response between the two cvs to two extracts was different. Whereas, the roselle extract improved some growth traits and some yield components. While senna extract improved other yield components. Therefore, it could be recommended to spray Egyptian cv.with vitamins complex and it be avoided to apply on Iraqi cv.next. It was recommended to characterize the active constituents of roselle and senne extracts to determine the stimulator and activator of it then use as second plant growth regulators. |
