The present study has been carried out during the growing season of 2013 in Chabaish, Dhi Qar to study the impact of Salicylic acid spraying at different concentrations (50 and 100 mg / L) in addition to the control treatment (spraying with distilled water) on some physical characteristics which were the total fresh weight of the fruits, flesh weight and the total weight of seeds, as well as, the length and diameter of fruits and Chemical characteristics (the percentage of water content, dry matter and total soluble solids) at different growth stages of the cultivar Almiasa.

Regarding the interaction between growth stage and the concentration of Salicylic acid concentrations; the results revealed that the khalal stage at Salicylic (50 mg /L) recorded the highest averages with significant differences in the following parameters fresh weigh of fruits ,flesh weight of fruits, seed weigh, the length and diameter of fruit which were 9.094 g ;6.762g ;1.329g ;5.467cm and 1.900 cm, respectively while ,the chemical analysis results showed that the Salicylic concentrations at( 50 mg /L) significant effect on the water connect at khalal stage among other treatments and reported the percent 81.34%,the dry matter at Ratab stage and control treatment was the highest percent and reported 76.25% ,the Salicylic concentrations at( 50 mg /L) led to significant reduction at Ratab stage for the total soluble solid percent which was 28.70%.
