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 in various research directions under changing condition.

Results from study are presented in this book. This book certainly enhances learning among researcher, scientists, students and farm mangers and helps planning research studies. The author appreciate the efforts of Barthlemy Chaton and his team in facilitating and highly acknowledge publishing of it by LAMBERT Academic Publishing, for technical knowledge sharing internationally.
