The supply of water to the plant in the crop field at regular intervals is called irrigation. Sprinkler method is useful in water-scarce areas such as deserts, and where there is less or uneven rainfall. It consists of the main pipe, to which many pipes are attached in a series.

The crops that are grown in the winter season between October and March, and are not dependent upon the monsoon are called Rabi crops. A few examples of Rabi crops are wheat and legumes like gram and pea.
