A practical Approach for water Use Efficiency in Arid Areas

Abstract

A practical approach for water use efficiency (WUE) relying on the actual amount of applied water was examined from both theoretical and practical stand points. Pearlmillet {Pennisetum americanum (L.) K. Schum), sorghum (Sorghum biclor L. Moench) and barley (Hordeum vulgare L.) were planted under sprinkler irrigation gradient at Tucson, Arizona, U.S.A; Al-Ain, United Arab Emirates and Rumais, Sultanate of Oman, respectively. Equations were developed for WUE for both yield and forage production.
