Pterocarpus marsupium

Pterocarpus marsupium, widely known as the Indian Kino tree, is a large deciduous species belonging to the Fabaceae family. It is a highly valued tree species in both industrial forestry and traditional medicine, recognized for its extreme durability and the distinct resin it produces when the bark is injured.

The native habitat of this species is spread across the tropical forests of India, Nepal, and Sri Lanka. It typically grows in hilly terrains and dry deciduous forest zones. Due to its economic importance and habitat loss, the tree is now a subject of organized cultivation in agroforestry systems aimed at sustainable resource management and biodiversity conservation.

Botanically, Pterocarpus marsupium can reach heights of up to 30 meters. It features pinnate leaves and produces yellow flowers arranged in large panicles. The fruits are circular, winged pods containing a single seed. The wood itself is noted for its high resistance to fungi and termites, making it a premium material for heavy construction and carving.

The tree thrives in well-drained, sandy loam soils and requires plenty of sunlight to mature properly. While it shows good drought tolerance once established, irrigation is essential during the early years of development. Successful cultivation requires maintaining appropriate spacing between trees to ensure that the crown can develop fully without competitive stress.

The economic value of this tree covers several sectors:

• Production of high-quality, durable timber for furniture and structural building.
• Extraction of "Kino," a therapeutic gum resin used in pharmaceuticals.
• Use in traditional medicine for blood sugar management and skin health.
• Integration into agroforestry to improve soil stability and local climate conditions.

The plant is susceptible to various fungal pathogens, especially in high-humidity areas, which can lead to root and bark decay. Additionally, wood-boring beetles and certain defoliators are known to cause significant damage to plantation stands. Integrated pest management, focusing on early detection and maintaining soil health, is vital for the successful growth of this species.
