The method of watering the crops at regular intervals is called irrigation. The two methods of irrigation are:- Sprinkler system- it has an arrangement of vertical pipes with rotating nozzles. It is more useful in sandy and uneven areas where there is insufficient water. Drip system- water falls drop by drop directly near the roots of plants. That's why it's called drip system. It is the best technique to water the plants. Water is not wasted at all.
