Name one staple crop of India and the regions where it is produced.
Rice is the staple food crop of a majority of the people in India. It is a kharif crop which requires high temperature (above 25°C) and high humidity with annual rainfall above 100 cm. In areas of less rainfall, it grows with the help of irrigation.
Rice is grown in the plains of north and north-eastern India, coastal areas, and the deltaic regions. The development of a dense network of canal irrigation and tubewells has enabled its cultivation in areas of less rainfall, such as Punjab, Haryana, western Uttar Pradesh, and parts of Rajasthan.
