Produce
Besides quinine, numerous others agricultural produce was grown. Here are some examples.

Rubber, Hevea
Rubber or Hevea, comes from latex, the juice from the rubbertree. The latex is bled from the tree by making incisions in the bark. On the latest point of this tap a spout is introduced so that the latex flows into cups. These cups are gathered regularly in buckets. These buckets are taken to the rubber factory or a gathering station in the forest.
There has been much experimentation with the tapping methods. The key was to achieve a balance between yearly productivity and the time required for the bark to recover.
