Upland cotton

Upland cotton (Gossypium hirsutum L.) is the most widely cultivated species of cotton in the world, belonging to the Malvaceae family. It accounts for the vast majority of global cotton production, serving as the primary raw material for the international textile industry.

Native to Central America and Mexico, this species has been domesticated and adapted to diverse climates worldwide. Today, it is grown extensively across tropical and subtropical zones, with major producers including the United States, China, India, and Uzbekistan, where it thrives in long, warm growing seasons.

The plant exhibits a robust structure, characterized by a deep taproot, branching stems, and broad lobed leaves. Its fruit is a seed capsule or "boll." Inside the boll, seeds are covered in a dense layer of cellulose fibers, which are harvested to produce yarn, fabric, and numerous industrial products.

Cultivation requires specific environmental conditions, including high temperatures and substantial solar radiation. Upland cotton performs best in well-drained, nutrient-rich soils. Irrigation management is critical, particularly during the flowering and boll-setting stages, to ensure high yields and optimal fiber quality.

• Requires 150–200 frost-free days.
• Sensitive to excessive rainfall during harvest.
• Susceptible to pests like boll weevils and aphids.
• Requires effective weed control programs.
• High nitrogen and phosphorus demands.

Management of the crop involves rigorous pest control strategies to mitigate damage from insects and pathogens such as Verticillium wilt. Beyond fiber, the crop is highly valued for its seeds, which are processed to extract cottonseed oil, used in food products, and the remaining meal, which serves as a high-protein feed for livestock.
