“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?

(a) Cotton
(b) Jute
(c) Sugarcane
(d) Tea
Answer: (a)
Explanation:
- Cotton cultivation is feasible in different soil types globally.
- However, deep fertile soils that possess sufficient humus content, high water retention capacity, and good internal drainage are most favorable for cotton growth.
- Cotton can be grown in regions where the number of frost-free days available is a minimum of 180-200 days.
- For germination to occur at an optimal rate, the temperature range required is between 20 to 30 degrees Celsius.
- Lower temperatures below 18 degrees Celsius can cause delayed germination of cotton.
Therefore, option (a) is the correct answer.
