Usage
The unripe kernel and the crown of the trunk are eaten. They are also preserved in vinegar. The young immature nuts are eaten. The juice from the fruit pulp is eaten with sugar and cassa meal. The pulp yields an edible oil.
Cultivation
Plants are grown from seed. Seed may take 6-18 months. Seed need to be sown in their permanent position because they have a long sinker which may go 4 m deep. To overcome this problem in nurseries people stack several bottomless pots on top of each other.
