Rice is a kharif crop grown in the plains of north and north-eastern India, coastal areas and deltaic regions. It requires high temperatures (above 25°C) and high humidity with annual rainfall above 100 cm. In areas with less rainfall, it grows with the help of irrigation via canals and tubewells.

Geographical conditions for the growth of rice: (a) It is a Kharif crop which requires high temperature, (above 25 C) and high humidity with annual rainfall above 100 cm. (b) In the areas of less rainfall, it grows with the help of irrigation. For example, development of dense network of canal irrigation and tubewells have made it possible to grow rice in Punjab, Haryana, western Uttar Pradesh and parts of Rajasthan.
Rice cultivation necessitates specific geographical conditions for its successful growth. It thrives in warm climates with temperatures ranging from 20°C to 37°C (68°F to 98.6°F) throughout the growing season. High humidity, abundant sunlight, and an annual rainfall of about 100-200 cm (39-79 inches) are crucial elements. Adequate water availability, either from rainfall or irrigation, is imperative, and the paddy fields where rice is grown are often flooded during the cultivation period.
The preferred soil for rice cultivation is well-drained, fertile, and rich in organic matter. Loamy or clayey soils that retain moisture are favored, with a pH range of 5.0 to 7.0. Moreover, flat or gently sloping terrain is ideal for rice cultivation to facilitate water retention in paddy fields. These geographical prerequisites collectively create an environment conducive to successful rice cultivation, ensuring the required warmth, water, and soil fertility for optimal growth and high yields.
