This research was conducted in the research field of Birzeit University - Palestine, in order to study the possibility of reusing reclaimed municipal wastewater of Al-Bireh wastewater treatment plant for corn irrigation rather than discharging it into wadis. Moreover, soil quality will be studied before and after the experiment in order to study the effect of using reclaimed wastewater in irrigation. The specific objectives of this research are to compare the effect of treated wastewater and tap water in combination with artificial fertilizer on the corn constituents and dry yield and on soil...
