About cotton cultivation-

Highest cotton producing state of India is Gujarat. Apart from Gujarat, Punjab, Rajasthan, Tamil Nadu, Madhya Pradesh are main producers of cotton. Black clay soil and 25℃ temperature is perfect for cotton production. For cotton cultivation first soil is prepared to sow the seeds. Crop rotation is essential for cotton crops. As continuous production of cotton causes lack of nutrients in soil and pest and disease problems. Application of N,P,K and other nutrients in soil is important for a good cotton crop. In the end harvesting and yield of cotton involves following steps – 

1. Ginning – The process of removing seeds from cotton pods is called ginning. Ginning can be done by using hands or machines. 

2. Spinning – The process of changing cotton fibre into cotton yarn is called spinning. This is done by passing cotton fibres through the carding machine which separates the fibres. 

3. Weaving – The process of making a fabric by joining two or more than two sets of cotton yarn together is called weaving.
