CORNy

Maize (Zea mays), known as corn in some countries, is a cereal grain domesticated in Mesoamerica and subsequently spread throughout the American continents. After European contact with the Americas in the late 15th and early 16th century, maize spread to the rest of the world.

Hybrid maize, due to its high grain yield as a result of heterosis ("hybrid vigour"), is preferred by farmers over conventional varieties. While some maize varieties grow up to 7 metres (23 ft) tall in certain locations,[1] most commercially grown maize has been bred for a height of 2.5 metres (8 ft). Sweet corn is usually shorter than field-corn varieties.

Maize is the most widely grown crop in the Americas (280 million tonnes annually in the United States alone). Whereas India produces about 12 million metric tonnes per year..
