Question 87: Geography
“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 centimeters 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 that crop ?
AnswerUPSC’s answer is (a).
The description matches cotton: a subtropical crop that needs at least 210 frost-free days, 50 to 100 cm of rainfall and a light, well-drained soil that retains moisture, such as black soil. Jute needs a hot, humid climate with heavy rain, sugarcane is a tropical crop needing much water, and tea needs heavy rain and acidic, well-drained soil.
Why each option is right or wrong
- (a) Right: cotton fits the frost-free days, rainfall and soil.
- (b) Wrong: jute needs a hot, humid climate and heavy rainfall.
- (c) Wrong: sugarcane is tropical and needs more water.
- (d) Wrong: tea needs heavy rainfall and acidic soil.
