investigation of mineral elements concentration in leaf and root grafted and ungrafted melon (zard-e -jalali accession from inodorus group) under deficit irrigation on drip irrigation system

the effects of grafting under conditions of deficit irrigation, on content of minerals leaf and root, evalutate in a field experiment under deficit irrigation was conducted with split plot in a randomized complete block design with three replications, in the research field of higher education institution imam khomeini (ra) under the ministry of agriculture in karaj, during 2014. in this study, a landrace melon from inodorus group (zard-e-jalali) as the scion and commercial varieties of cucurbita rootstocks cv., ‘shintozwa’and ‘ferro-rz’was used as the rootstock. grafted melons upon commercial varieties of cucurbita with own-rooted and ungrafted at three irrigation levels 60, 80 and 100 percent based on total available water depletion with drip irrigation system were evaluated. comparison of means showed that maximum (40.76 ton.ha-1) and minimum (31.16 ton.ha-1) total yield, related to ‘shintozwa’rootstock and self grafted respectively. the results showed that the irrigation levels and rootstocks had a significant effect (p
