Explanation
Sugarcane is a tropical as well as a subtropical crop. It is a long-duration crop that thrives in hot and humid climatic conditions.
- Statement 1 is Incorrect: Sugarcane is not exclusively a temperate crop. It is primarily a tropical crop that also grows well in subtropical regions. It requires a long growing season without frost.
- Statement 2 is Correct: The crop requires a hot and humid climate with an ideal temperature range of 21°C to 27°C. Low temperatures and frost are detrimental to its growth and sugar accumulation.
- Statement 3 is Correct: Sugarcane requires an annual rainfall between 75 cm and 100 cm. In regions with lower rainfall, irrigation is essential to maintain productivity.
Key Takeaway: Sugarcane is a tropical and subtropical crop requiring a hot, humid climate (21°C-27°C) and moderate rainfall (75-100 cm), with irrigation needed in drier areas.
