Performance of Drip irrigation has been recognized throughout the world especially in terms of water saving. Even though a lot work has been done but still, a lot need to be done, under changing field environment. Present study focus on the performance evaluation of different types of emitters in orchards irrigated field environment. Further the energy loss on lateral geometric characteristics and hydraulic variability analysis was made and the results are presented in this book. This book certainly enhance learning among researcher, scientists, students and farm mangers and helps planning research studies. The authors appreciate the efforts of Barthlemy Chaton and his team in facilitating and highly acknowledge publishing of it by VDM Publishing House Ltd., for technical knowledge sharing internationally.
