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?

Accepted Answer

Option (a) is the correct answer: Cotton is grown on a variety of soils across the world. Deep, fertile soil with adequate humus and high water holding capacity and good internal drainage is best suited for growing cotton. Cotton can be grown in places wherever, at least 180-200 frost free days are available. Optimum temperature for germination 20-30°C. Germination will be delayed if the temperature is <18°C.The climatic conditions in the cotton growing regions of India show considerable variations:High temperature of about 45 degree Celsius during sowing and seeding emergenceLow temperature accompanied by occasional frost coinciding with the picking periodModerate rainfall ranging from 300-700 mm in the north zoneIn the Southern and Central zones, the climate is equal.Source: GC Leong
