UPSC CSE Prelims 2020

‘The crop is subtropical in nature. A hard frost is injurious to it. It requires at least 210 frost-free days and 50 to 100 centimetres of rainfall for its growth. A light well-drained soil capable of retaining moisture is ideally suited for the cultivation of the crop.’ Which one of the following is the crop?

EXPLANATION

Correct Option

The characteristics provided in the question accurately describe the cultivation requirements for cotton.

  • Cotton is a subtropical crop, highly susceptible to frost, which can severely damage the plant.
  • It necessitates a long frost-free period, typically around 210 days, for optimal growth and boll development.
  • The crop requires moderate rainfall, generally ranging from 50 to 100 centimetres, which can be supplemented by irrigation in drier regions.
  • Light, well-drained soils, such as black cotton soil or alluvial loams that possess good moisture-retaining capacity, are ideal for its cultivation.

Incorrect Options

  • Jute: This crop thrives in a hot and humid climate, typically requiring 100 to 150 centimetres of rainfall, which is higher than the specified range.
  • Sugarcane: It is a tropical crop that demands a hot and humid climate with significant water availability, generally 75 to 150 centimetres of rainfall, and a longer growth period, which does not align with all the given conditions.
  • Tea: Tea cultivation requires a cool, moist climate with abundant and well-distributed rainfall, usually between 150 to 250 centimetres, and well-drained loamy soils on hill slopes, differing from the conditions mentioned.
