Cotton is a soft, fluffy fiber that grows in a boll around the seed of cotton plants. It is an economically important crop used for textiles, cooking oil from seeds, and animal feed. The four major species of domesticated cotton are Gossypium hirsutum, G. barbadence, G. herbacium, and G. arboreum. Key steps in cotton production include soil preparation, planting, growth stages, and picking. Factors like pests, diseases, weeds, and climate impact cotton yields.
