EFFECTS OF IRRIGATION WITH TREATED WASTEWATER ON THE PHYSICAL PROPERTIES AND CHEMICAL COMPOSITION OF WHITE CORN

In order to investigate the effects of applying treated waste water as a source of irrigation on both physical properties and chemical composition of white corn, this study was conducted at a land in the neighborhood of Gaza Waste Water Treatment Plant (GWWTP). The land was divided into three groups of cells; each group was irrigated with one water type. The Irrigation types were: (1) Irrigation with Tap water (TW) The control, (2) Irrigation with Treated Waste Water (TWW) and (3) Alternating Irrigation with both TW and TWW. The results indicated that the second set, as compared to the control, had not recorded significant difference in the physical properties, whereas the third set had recorded lower physical properties and had seen significant difference. On the other hand, the chemical analyses demonstrated high increase in concentration of each of TKN, TP and K in plant’s leaves of the second set.
