Evaluation of Treated Wastewater Irrigation on Growth,
Chemical Composition and Essential Oils of Some Woody Trees

Abstract: Rapid increases in population and industrial growth have led to use low quality water such as
drainage and saline water as well as waste water for irrigation. A pot experiment was conducted during
2018/2019 and 2019/2020 seasons in Timber Trees and Forestry Department, Horticulture Research Institute,
Agricultural Research Centre, Egypt, to evaluate effects of treated wastewater irrigation on growth, chemical
composition and essential oils extracted from seedlings of three woody plants (Myrtus comunis, Eucalyptus
camaldulensis and Cupressus sempervirens). These seedlings were grown in sandy loamy soil irrigated with
two types of irrigation water, tap water and treated waste water. The obtained results revealed that, the use of
treated waste water was superior than tap water in improving all growth parameters of the three woody plant
species beside its positive effect on their chemical composition. As regard essential oils, data showed that
waste water irrigation increased oils quantity reaching, 41.3, 78.6 and 37.5% over control of the three plant
species respectively with slight variable changes in its components .Also, data revealed that there is no
accumulation of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in essential oil in spite of its presence in
traces in plant leaves. Thus, treated wastewater can be safely used as irrigation water source for these plant
species as a timber tree or medicinal plants to partially solve the problem of the shortage in irrigation water and
essential oil production
