The first kinds of corn cultivated in Switzerland in the Young Stone Age (about 7,500 years ago) were wheat and barley. These kinds of corn were not indigenous in Europe before they were first grown here, meaning they have had to be imported from outside. In the near East, the cultivation of corn was already in use for about 10,000 years ago. In those areas, barley and wheat were indigenous as wild grass. From this area, these crops and the knowledge of how to cultivate them has spread over the Mediterranean and the Balcan into Switzerland.
