$\Huge\mathcal\blue{\underbrace{\overbrace{\mid{\orange{Answer}}\mid}}}$

Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation.

Answer 2

Answer:

The distribution in rainfall is uneven and uncertain which either causes famines or drought. By means of irrigation we can check both the problems. Different water requirements of different crops can only be met through irrigation facilities.
