Tree cotton

Tree cotton (Latin: Gossypium arboreum L.) is a significant agricultural crop belonging to the Malvaceae family. Although referred to as "tree" cotton, it is typically managed as a shrub in commercial farming systems. It is one of the oldest domesticated cotton species, known for its deep historical role in the textile history of the Indian subcontinent.

The origin of Gossypium arboreum is traced back to South Asia, specifically India and Pakistan. Its distribution area primarily spans tropical and subtropical regions where it has been cultivated for centuries. Unlike other widely grown species, this cotton variety demonstrates superior resilience to extreme local weather conditions and specific soil pathogens found in its native ranges.

Botanically, the plant is characterized by a sturdy, woody stem structure and palmately lobed leaves. The flowers are typically yellow, sometimes with a purple base. The fiber produced by G. arboreum is categorized as short-staple. While it may lack the length of long-staple varieties, it is highly durable and exhibits excellent strength for textile applications.

The agronomic requirements for tree cotton include high temperature thresholds and significant solar radiation during the ripening phase. The crop thrives in fertile, well-drained loamy soils. Proper irrigation management is essential, particularly during the flowering and boll development stages, alongside careful weed control to prevent competition for nutrients.

The primary economic use is the production of fiber for textiles, especially for coarse, rugged fabrics. Furthermore, cotton seeds are processed for oil, which has industrial and food-grade applications. Growers must combat common pests such as the cotton bollworm and spider mites, while also monitoring for fungal diseases like Fusarium wilt through systematic crop rotation.
