The various traditional method of irrigation are

1)Moat(pulley system)

2)Chain pump

3)Dhekli

4)Rahat(lever system)

Traditional method of irrigation are cheaper but less efficient.Pumps are commonly used for lifting water.These pumps run by electricity,diesel,biogas or solar energy. When a pump is used to draw out water from a narrow well,it is called tube-well.They are used increasingly for lifting underground water to be used for irrigation in agriculture.

Modern methods of irrigation

The two main modern methods of irrigation are:
1) Sprinkler system : A main pipeline is laid in the field.Perpendicular pipes having rotating nozzles at the top are joined to the main pipelines at regular intervals.When water from a tube-well is allowed to flow through the main pipelines under pressure with the help of a pump,it escapes from the rotating nozzles.This water gets sprinkled on the crop plants as if it is raining.
