PRODUCTION OF JOJOBA (SIMMONDSIA CHINENSIS) PLANT IN JORDAN BY UTILIZATION OF TREATED WASTE WATER

Abstract

In arid and semi-arid countries such as Jordan, water is becoming scarce resource to consider any sources of water, which might be used economically and effectively to promote further development. Rapid increase of human population and the industrial growth have led to using low quality water, such as drainage and saline water as well as wastewater for irrigation. The possibility of growing energy crops such as Jojoba (Simmondsia chinensis (Link) Schneider) which is xerophyte shrub that is economically promising, ecologically posing low risk of link to human food chain, and physiologically surviving high water and salinity stress. This research was conducted at the site near Ramtha wastewater treatment plant in northern of Jordan. A field experiment was carried out to investigate the impact of different sewage concentrations (0, 25, 50, 75 and 100%) on growth parameters and leaf chemical constituents of jojoba plants during the period January 2010 - January 2011. During the entire period of
