seed/nut yielding
7% -
8% oil. The
tree's wood is called
breadnut wood and has a density of
500 -
610 kg/m³. Regarding firewood production the
tree's growing speed is
fast, it's energetic value is
4500 ckal/kg and the wood's drying speed is
medium. After
30 years the
tree can be totally removed as it reached its commercial and ecological goal.
Artocarpus camansi has a lifespan of
70 years.
