Irrigation is the process by which water is supplied to the crops. The frequency of irrigation varies from season to season and crop to crop. Plants contain nearly 90% water, and need water for proper development of flowers, fruits and seeds. Irrigation can be done by two methods - Traditional methods and Modern methods. Some of the traditional and modern methods are elucidated.
*Traditional methods of irrigation require animal and human labour to draw water. these are the cheapest methods available and are still in use. These include moat, chain pump, dhekli and rahat.
