  • The wood is having good demand from ply wood industries.
  • Melia Dubia is the fastest growing tree and the wood from this tree is used in Plywood Industry.
  • It is commonly found in the hills at elevations ranging from 600 – 1800m.
  • It is occasionally planted for ornament and makes a handsome avenue tree and a shade tree in plantations.
  • It grows rapidly and is used for afforestation purposes.

  • In the indigenous system of medicine, the leaves of Melia azedarach Linn. (Family - Meliaceae) are reported to be useful in the treatment of urinary stones.
  • The wood can be sold for match and veneer industry.
  • With the development of new cloned propagation of Melia dubia plantation(Malabar neem tree- a very fast growing tree, with high calorific value)which can be used as fire wood for power generation has opened new opportunities for small and medium bio-mass power generation projects.
  • Melia dubia has the unique feature of growing to 40 feet within two years from planting and can be mechanically pruned and harvested.
  • As the demand for Melia wood is quite high from the plywood industry, minimum profit of about Rs.40,000 per year from an acre can be ensured for the farmers.
  • Melia dubia has been tested positive for pulpwood and recorded a pulp yield of 50.3% along with kappa number of 19.60.
  • The various parts of Melia dubia (Meliaceae) plant was observed to be used by the local tribes of Nilgiris for various infections.
  • Literature reveals that fruits of Melia dubia is considered to be important in colic and skin diseases and also as anthelmintic.
  • Leaves and seeds of this plant were reported to possess two tetranotriterpenoids, compositin and compositolide.
  • The tree with the minimum size of 16inches girth is saleable at the minimum rate of Rs 2000 per tonne for match industry and for
    veneer industry, the market rate is little higher.
