best_answer

The supply of water to crops at regular intervals is called irrigation. Water is essential for proper growth and development of plants. Plants absorb water and minerals through the roots.  The different sources of irrigation are rivers, wells, ponds, tube wells, lakes, dams and canals. There are various traditional as well as modern methods of irrigation which differ from soil to soil, crop to crop, and season to season. 

Two methods of irrigation which conserve water are:

(i) Sprinkler system: The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. When water is allowed to flow through the main pipe under pressure with the help of a pump, it escapes from the rotating nozzles. It gets sprinkled on the crop as if it is raining.

(ii) Drip system: The water falls drop by drop directly near the roots. So it is called the drip system. Water is not wasted at all. It is a boon in regions where the availability of water is poor.
