Abstract

Irrigation and drainage are the essential ingredients in raising crops and
increasing food production. Due to the aberrant weather for the past few years and
environmental changes, irrigation is becoming one of the critical and scarce factors for
assured production. The basic level of knowledge about irrigation and drainage needed
by agricultural graduates, farmers and other concerned people has not been fulfilled so
far although there have been many forays in the direction. The author hopes that this
article succeeds in its mission of illustrating the basic principles of irrigation and drainage
to agriculture students, teachers, researchers, extension workers, farmers and all those
related toagriculture.
