“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

Explanation

Ideal conditions for the cotton plant are: Temperature: Cotton grows in tropical and sub-tropical warm humid climate. Annual temperature required is between to 20 to 28 Degree C. Equitable temperature distribution and bright sunshine is desirable. Rainfall: Annual Rainfall of 55 to 100 cm is ideal for cotton. However, rainfall during harvest is harmful. Frost Free days: 180 frost free days are the bottom line for cotton cultivation. Atleast 210 frost free days are desirable for cotton production. Soil: Fertile saline soil with high water retention capacity is ideal. Loamy soil with high calcium carbonate is best suited for cotton cultivation. Therefore, the correct answer is (a).
