[UPSC Civil Services Exam – 2021 Prelims]

(b) Sunflower

(c) Pearl millet

(d) Red gram


Answer: (a)

Explanation:

  • Sugarcane is the world’s largest crop in terms of production and belongs to the Poaceae family of true grasses.
  • It is grown as a Kharif crop in India, requiring a hot and humid climate with an average temperature of 21°C to 27°C and 75-150 cm of rainfall.
  • In areas with lower rainfall, irrigation is necessary. Sugarcane can grow in any soil that can retain moisture, but the ideal soil is deep, rich, and loamy, with a good supply of nitrogen, calcium, and phosphorus.
  • The soil should be neither too acidic nor too alkaline. The crop requires 1500-2500 mm of water during its growing period, and it is highly sensitive to drought. Therefore, sugarcane is a suitable choice for cultivation.

Therefore, option (a) is the correct answer.
