Field corn in the context of "Maize"

Sweet corn (Zea mays convar. saccharata var. rugosa), also called sweetcorn, sugar corn and pole corn, is a variety of maize grown for human consumption with a relatively high sugar content.

Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Sweet corn is picked when still immature (the milk stage) and prepared and eaten as a vegetable, unlike field corn, which is harvested when the kernels are dry and mature (dent stage). Since the process of maturation involves converting sugar to starch, sweet corn stores poorly and must be eaten fresh, canned, or frozen, before the kernels become tough and starchy.

Corn stover consists of the leaves, stalks, and cobs of corn (maize) (Zea mays ssp. mays L.) plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop and is similar to straw from other cereal grasses; in Britain it is sometimes called corn straw. Corn stover is a very common agricultural product in areas of large amounts of corn production. As well as the non-grain part of harvested corn, the stover can also contain other weeds and grasses. Field corn and sweet corn, two different types of maize, have relatively similar corn stover.

Dent corn, also known as grain corn, is a type of field corn with a high soft starch content. It received its name because of the small indentation, or "dent", at the crown of each kernel on a ripe ear of corn. Reid's Yellow Dent is a variety developed by central Illinois farmer James L. Reid. Reid and his father, Robert Reid, moved from Brown County, Ohio, to Tazewell County, Illinois, in 1846 bringing with them a red corn variety known as "Johnny Hopkins", and crossed it with varieties of flint corn and flour corn. Most of today's hybrid corn varieties and cultivars are derived from it. This variety won a prize at the 1893 World's Fair.

Most of the corn grown in the United States today is yellow dent corn or a closely related variety derived from it. Dent corn is the variety used in food manufacturing as the base ingredient for cornmeal flour (used in the baking of cornbread), corn chips, tortillas, and taco shells. It is also used to make corn syrup. Starch derived from this high-starch content variety is turned into plastics, as well as fructose which is used as a sweetener (high-fructose corn syrup) in many processed foods and soft drinks.

Maize (/meɪz/; Zea mays), also known as corn in North American English, is a tall stout grass that produces cereal grain. The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ears. The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and squashes in the Three Sisters polyculture.

Maize relies on humans for its propagation. Since the Columbian exchange, it has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat and rice. Much maize is used for animal feed, whether as grain (fodder) or as the whole plant, which can either be baled as forage or made into the more palatable silage. Sugar-rich varieties called sweet corn are grown for human consumption, while field corn varieties are used for animal feed, for uses such as cornmeal or masa, corn starch, corn syrup, pressing into corn oil, alcoholic beverages like bourbon whiskey, and as chemical feedstocks including ethanol and other biofuels.
