Explanation:
It helps to cultivate superior crops with the water supply as per need of the crops. Ultimately it helps in economic development. Irrigation water improves water conditions in the soil, increases the water content of plant fibers, dissolves nutrients & makes them available to plants.

It is important to increase the area under irrigation because:
It is necessary to reduce the dependency on rainfall and stabilize the cropping pattern.
For example in South India without perennial rainfall, water supply replenishment is dependent on a cycle of dry seasons alternating with monsoon seasons.
Monsoons are not certain in nature. So, farming cannot entirely depend upon rains.
Irrigation also allows farmers to grow more crops in one year on the same land
The constant availability of water for irrigation provides a sense of stability to the farmer, and also encourages him to practise newer farming methods and patterns to maximise the productivity.
how it is done?
To irrigate is to water crops by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone. ... This water was used for drinking, washing, and irrigation. Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops.
ways for doing:
The three main methods of irrigation are surface, sprinkler and drip/micro. Water flows over the soil by gravity for surface irrigation. Sprinkler irrigation applies water to soil by sprinkling or spraying water droplets from fixed or moving systems.
