Tarwi: Tarwi
(Lupinus mutabilis)

Tarwi is an erect, annual, cool-season nitrogen-fixing plant that grows up to 2.5 m in height. For human consumption, the seeds must be soaked in water for several days to remove bitter alkaloids. The seeds are high in protein, pressed for oil, and fed to livestock. Tarwi is a good green manure or cover crop for the highland tropics.
