(i)    Cotton : Cotton plants are usually grown at places having black soil and warm climate. The fruits of the cotton plant (cotton bolls) are about the size of a lemon. After maturing, the bolls burst open and the seeds covered with cotton fibres can be seen.It looks like a field covered with snow.
From these bolls, cotton is usually picked by hand. Fibres are then separated from the seeds by combing. This process is called ginning of cotton. Ginning was traditionally done by hand. These days, machines are also used for ginning.

Cotton is cultivated where warm and sunny weather stays for at least half of the year. Cotton plants require warm temperature ranging between 21º C to 27ºC with sunny and dry weather. By the time of harvesting rainfall between 50 cm to 80 cm is another conducive condition for its growth. Black soil, which has the ability to retain moisture is best suited for cotton cultivation. When cotton crop grows to maturity, the seeds with their fibres are harvested. Fibres are separated from the seeds and raw cotton is then shipped to textile factories.
