Incan Crops

[Adolf Ceska]

There is an excellent book on food plants cultivated by Incas:

Lost crops of the Incas : little-known plants of the Andes with
promise for worldwide cultivation / report of an ad hoc panel
of the Advisory Committee on Technology Innovation, Board on
Science and Technology for...  Washington, D.C. : National
Academy Press, 1989.

I hope you can find it in a library.
