11.1 INTRODUCTION
Water scarcity and drought are the major factors constraining agricultural crop production in arid and semi-arid zones of the world. Innovations for saving water in irrigated agriculture and thereby improving water use efficiency (WUE) are of paramount importance in water-scarce regions. Therefore, use of new irrigation technologies in agriculture have aimed at increasing crop production, and new developments in irrigation technologies are of great importance. Efficient use of irrigation is becoming increasingly important, and drip irrigation (DI) may contribute substantially to the best use of water for agriculture, improving irrigation efficiency [28]. Therefore, adoption of modern irrigation techniques must be emphasized to increase WUE. These modern techniques must result in efficient water delivery and high productivity while minimizing water use [1].
