The reuse of agricultural drainage water in agriculture is something commendable as it is almost a requirement strategically contributes to increase the sources of fresh water. The aim of this study is to investigate the effect of irrigation with agricultural drainage water– providing another source of water for irrigation leading to face water sacristy– on two different of olive cultivars` seedling (Manzanillo & Picual) grown at Borg El– Arab city, Alexandria Government, Egypt. This work covers an application of irrigation using five transactions of 0, 25, 50, 75 and 100% agricultural drainage water on two cultivars of olive seedlings. Effect of irrigation process on growth (seedlings` length, branches` number, leaves` number) of both cultivars was demonstrated in death of more than 50%, death approaches to 50% and continual alive plant for100%, 75% and from 25–50%, respectively for irrigation transaction replicates after six months. There are no significant differences between control (0%) and irrigation with (25–50%) agricultural drainage water. On the other hand, changes in the protein profile of total protein (TP), peroxidase (PO) and chitinase activities in leaves of olive seedlings could be briefed in the increase in TP content values for leaves was higher in picual cultivar of untreated control seedlings than in manzanillo while 100% transaction both cultivars did not differ significantly. Chitinase activity was differed significantly in manzanillo in response to different irrigation water treatments in compare to seedlings of picual cultivar. N and K contents in leaves were significantly increased with increasing agricultural drainage water with a value of 0.18 and 0.06% LSD (0.05), respectively, while P content was increased gradually with increasing the drainage water a value of 0.06 % LSD (0.05), in both olive cultivars.
