Greek agriculture focused on a few basic crops, especially wheat, barley, grapes, figs, and olives. Farmers grew wheat and barley in the few fertile areas of Greece, notably in the plains of Argos and Olympia in the south.
In addition to the emergence of farming in the Fertile Crescent, agriculture appeared by at least 6,800 B.C.E. in East Asia (rice) and, later, in Central and South America (maize and squash). Small scale agriculture also likely arose independently in early Neolithic contexts in India (rice) and Southeast Asia (taro).
