Preface Water is now becoming the precious commodity. The demand for irrigation water has increased many times over the years to bring more and more area under irrigation and simultaneously for increasing cropping intensity and to provide food and fiber to our ever-increasing population. Bringing more area under irrigation without the improved management may lead to stress to water resources and average success in production and productivity. Micro irrigation refers the drip and sprinkler irrigation and so far the most efficient method of irrigation. Micro irrigation has many advantages over the conventional methods of irrigation. However, the method needs some knowledge and skill for appropriate application of it. This book Drip and Sprinkler Irrigation is intended as a text book of micro irrigation design and practices for the students of agricultural sciences and the professionals and workers in the field of micro irrigation. The book contains good numbers of numerical as example and task to get the students familiar to the requirements, complicacies, and possible remedies in actual working condition in addition to conventional broad and short questions. In every chapter of the book there are multiple choice questions to assist the students in attending competitive examinations.
