Abstract
Experiment was carried out during the growing season 2013 2014 in Special Nursery in Misan city to study the effect of soil application of organic compost at levels (0, 250 and 500 ml/seedling), and spraying with salicylic acid at two levels (0 and 200 mg / L) and the interaction between them in vegetative growth with traits, and were set up as a factorial experiment by using Randomized Complete Block Design with three replication. Results showed a significant effect of spraying salicylic acid at 200 mg / L significantly effects in vegetative growth traits compared to control, which gave the highest values of increase in length of stem , number of leaves , fresh weight , total chlorophyll ,dry weight, and stem diameter( 53.50 cm ,33.50 leaf ,19.43 g ,50.43 mg / g , 9.30 g and 2.73 mm, respectively), with the lowest values in control. application at compost tea soil addition at 500 ml / seedling significant effect on traits, which gave the highest values in of increase in length of stem , number of leaves , fresh weight , total chlorophyll ,dry weight, and stem diameter( 50.03 cm ,29.03 leaf ,17.43 g ,36.99 mg /g ,7.52 g and 2.50mm, respectively), compared with the lowest rates that resulted for control treatment( 42.01 cm , 24.23 leaf, 13.55 g, 24.55 mg / g , 6.05 g and 1.5 mm respectively), Interaction between and achieved the overlap compost tea application at 500 ml/ seedling and salicylic acid at 200 mg / L gave the highest in all the traits compared to the control which gave the lowest values.
