Biomass Production and Utilization
Full grown neem trees yield between 10 to 100 tons of dried biomass/ha,
depending on rainfall, site characteristics, spacing, ecotype or genotype.
Leaves comprise about 50% of the biomass; fruits and wood constitute one-quarter
Improved management of neem stands can yield harvests of about 12.5 cubic
meter (40 tons) of high quality solid wood/ha.
Neem wood is hard and relatively heavy and religious icons in some parts
The wood seasons well, except for end splitting.
Being durable and termite resistant, neem wood is used in making fence posts,
poles for house construction, furniture etc.
There is growing market in some European countries for light-colored neem
wood for making household furniture (H.Schmutterer, personal communication).
Pole wood is especially important in developing countries; the tree's ability
to resprout after cutting and to regrow its canopy after pollarding makes
it highly suited to pole production (National Research Council 1992).
Neem grows fast and is a good source of firewood and fuels; the charcoal
has high calorific value.
