8. Other
• Roots are nodulated
• Weed sensitive seedling
• Grass competition

9. Uses
• As timber : heartwood is mostly used for furniture, building
and carving and engraving
• Fuel wood : excellent for fuelwood as both sap and heart
wood have excellent calorific value, make best charcoal
for heating and cooking.
• Fodder : valuable , contains 15- 16 % crude protein and
50 % digestable nutrients
• Ecological value : leguminous plant and helps in
nitrogen fixation.
• Other : tree is excellent source of honey

10. • TRADITIONALLAY : slender tree twigs (called datun) are
first chewed as a toothbrush and then split as a tongue
cleaner.
• Medicinal values : used in Siddha medicine system for
skin disorders and stomach related issues
• As pesticides : Ethanolic extract of the fruits of Dalbergia
sissoo exhibited molluscicide effect against eggs of the
freshwater snail

phenomenon
• Fire : strong fire resistance
• Coppice : well coppices in 20 – 30 cm in diameter

18. • Browsing : Sensitive to grazing and browsing.
• Tree nature : Deciduous for short time, one of the most
gregarious forest tree. It grows up in more or less even
aged crops .
