Question

Which line divides India into rice producing areas and wheat producing areas and why?

Answer 1

The 150 cm Isohyet (line of equal rainfall) approximately divides India into rice-producing and wheat-producing regions.

• Areas East of the 150 cm Isohyet receive more than 150 cm rainfall, which is ideal for rice, a water-intensive crop.
• Areas West of the 150 cm Isohyet receive less rainfall, which suits wheat, a crop that requires less water.
