Chapter 4 · Question 3
Compare the geographical conditions required for rice and wheat.
Answer
Direct Answer
Rice needs high temperature, high humidity, and plenty of water, so it grows well in areas of heavy rainfall or irrigation. Wheat needs a cool growing season, bright sunshine at ripening, and moderate rainfall or irrigation, so it grows well in northern and north-western India.
Simple Explanation
Rice needs high temperature, humidity, and ample water. Wheat needs a cool growing season, bright sunshine, and moderate moisture, thriving in the north-west.
Exam-Ready Structure
Rice and wheat have contrasting geographical requirements:
Rice:
• Temperature: High temperature (above 25 degrees Celsius) throughout the growing period.
• Water: Requires abundant water; about 150-300 cm of rainfall or assured irrigation.
• Soil: Clayey loam and alluvial soils that can retain water are best.
• Distribution: Grown extensively in the Ganga-Brahmaputra plains, coastal deltas, and irrigated parts of peninsular India.
Wheat:
• Temperature: Cool growing season (10-15 degrees Celsius at sowing, rising to 20-25 degrees Celsius at ripening).
• Water: Moderate rainfall (50-75 cm) or irrigation; excessive rain damages the crop.
• Soil: Well-drained fertile soils, especially alluvial and black soils.
• Light: Bright sunshine at the time of ripening is essential for grain quality.
• Distribution: Concentrated in the north-western plains (Punjab, Haryana, western Uttar Pradesh) and parts of Madhya Pradesh.
Key contrast: Rice is a tropical crop needing abundant water and warmth; wheat is a temperate/cool-season crop needing cool weather and moderate moisture.
Key Points
- Rice needs high temperature, high humidity, and plenty of water, so it grows well in areas of heavy rainfall or irrigation.
- Wheat needs a cool growing season, bright sunshine at ripening, and moderate rainfall or irrigation, so it grows well in northern and north-western India.
