Maize (Zea mays, common name "corn" in American English) is a very common commercial crop in many parts of Ethiopia. I don't know when it was first introduced (probably quite a long time ago), but it is fast replacing many traditional crops because of its higher market value.

Steve Corbett

Maize has become a staple crop in Africa in general. The Portuguese likely introduced maize to Africa in the 16th century. Not sure where you might find information on the Omo Valley, specifically.

I found a very interesting article, if anyone is interested
