Consider the following statements:
1. Sugarcane needs annual rainfall above 200 cm.
2. Tea plants require a warm and moist frost-free climate throughout the year.
3. Cotton plants require a uniformly high temperature of 21- 30 degrees Celsius.
Select the correct answer using the code given below:
(a) 2 and 3 only
(b) 1 and 3 only
(c) 1 only
(d) 3 only
Explanation Statement 1 is not correct: Sugarcane grows well in tropical regions with 75 - 100 cm of rainfall well-distributed throughout the year. However, irrigation is necessary in areas of lower rainfall or even in areas of higher rainfall during the long dry spells.
Statement 2 is correct: A tea plant requires a warm, moist, and frost-free climate all year round to thrive; it grows best in tropical and subtropical regions with consistent rainfall and moderate temperatures. Key points about tea plant climate needs:
● Temperature: Ideally between 13°C and 32°C.
● Humidity: High relative humidity, around 80%.
● Rainfall: Frequent showers evenly distributed throughout the year, with total annual rainfall often exceeding 200cm.
● Frost intolerance: Cannot tolerate frost, so needs a frost-free environment.
Statement 3 is correct: It grows well within the average annual rainfall range of 50-100 cm. Cotton is a Kharif crop which requires 6 to 8 months to mature. It requires a high temperature, moderate rainfall or irrigation, and 210 days without freezing frost to mature.
