Abstract
An experiment was conducted out during the winter season of 2009-2010 at Al-Dair, Basrah Governorate The study included six treatments which were the combination of tow hybrid cultivars "Gwaher" and " Barcelona " and three concentration of salicylic acid (0,40 and 80) mg / L . applied with spraying two times at month intervals 20 day after sowing. Split-plot design was used at three replications. Duncan's multiple range test was used at probability of 0.05. Results could be summarized as follows: "Gwaher" hybrid was significantly superior in plant height, main stem diameter, lateral branch number, number of fruits per plant and percentage of dry matter in fruits ,while "Barcelona" hybrid significantly superior in fruit weight ( 118.7 gm) fruit length (12.1 cm), yield per plant (1.765 kg) and total productivity (9.709 Tone /donum). Treatment with salicylic acid at 40 mg/L significantly increased all vegetative growth characteristics and yield quality and quantity which is number of fruits per plant (17.6 fruit ) ,fruit weight (115.4 gm), yield per plant (2.009 kg), and total productivity (11.050 Tone /donum). The interaction between both treatment factor had a significantly effect on plant height, main stem diameter, fruit weight, total soluble solids in fruits, yield per plant (2.013 kg), and total productivity. The highest productivity obtained from salicylic acid treatment at 40 mg / L which (11,297 ton/donum) in "Hatouf" hybrid
