The production of corn (Zea mays mays, also known as "maize") plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of ...
Maize is a tall annual grass with a single stem, ranging in height from 1.2 m (4 ft) to 4 m (13 ft). [31] The long narrow leaves arise from the nodes or joints, alternately on opposite sides on the stalk. [31] Maize is monoecious, with separate male and female flowers on the same plant. [31]
U.S. maize (40 plants) Also, some other intermediate genomes, or admixtures of these clusters occur. According to these authors, "The maize of the Andes Mountains with its distinctive hand grenade-shaped ears was derived from the maize of lowland South America, which in turn came from maize of the lowlands of Guatemala and southern Mexico."

In North America, corn is the common word for maize. More generally, the concept of the Corn Belt connotes the area of the Midwest dominated by farming and agriculture, though it stretches down into the South as well reaching into Kentucky. [1] [2]
This classification increases understanding of the morphological characters of any particular family. As a disadvantage, this classification crops with different economic uses and morphological and other agrobotanical peculiarities when brought under one family do not generally bring out the economic importance of the individual crops.
Flint corn (Zea mays var. indurata; also known as Indian corn or sometimes calico corn) is a variant of maize, the same species as common corn. [1] Because each kernel has a hard outer layer to protect the soft endosperm, it is likened to being hard as flint, hence the name. [2]
McClintock explored the chromosomal, morphological, and evolutionary characteristics of various races of maize. [60] [32] After extensive work in the 1960s and 1970s, McClintock and her collaborators published the seminal study The Chromosomal Constitution of Races of Maize, leaving their mark on paleobotany, ethnobotany, and evolutionary ...
The protein from maize is further enhanced by protein contributions from beans and pumpkin seeds, while pumpkin flesh provides large amounts of vitamin A; with the Three Sisters, farmers harvest about the same amount of energy as from maize monoculture, but get more protein yield from the inter-planted bean and pumpkin.
