In order to study the effect of grafting on growth and fruit quality of melon under deficitirrigation the experiment was conducted as a split plot in a randomized complete block design with three replications during 2014 on the experimental farm of Imam Khomeini Higher Education center of Jihad-e-Keshawarzi in Karaj. Treatments consisted arrangement of four grafting (melon grafted on Shintozwa and Ferro-RZ, self grafted and ungrafted melon) and three irrigation levels 60, 80 and 100 percent, based on total available water depletion. The mean comparision showed that maximum (25.54 mg/g FW) and minimum (16.98 mg/FW) sucrose content of fruits was obtained in non-grafted plants under irrifation 80% and Souski Zard grafted on Souski Zard in irrigation 60% respectively. Also, the maximum (13.2%) and minimum (8.48%) of soluble solids was related to fruit of non-grafted plants under 80% irrigation level and non-grafted plants in irrigation 60%, respectively. The highest (7.58) and the lowest (5.29) learn points by the jury (panel test) related to fruit quality were irrigation 80 and 60 percent respectively. Also, there was no signifincant difference between deficit irrigation 80% and irrigation 100% in terms of total phenol content of fruit. The results showed that the fruit harvested from Soski Zand plant grafted on Shintozwa had better quality compared to control plants under deficit irrifation.
