Dent corn is a variety of field corn (Zea mays var. indentata) grown as a tall annual row crop for grain, feed and ethanol. It needs full sun, warm weather and fertile, well-drained soil to produce good ears.

About
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.
How to grow it
Dent corn is typically cultivated as a row crop grown commercially for grain and fodder. Cultivars developed for commercial cultivation are either single- or double-cross hybrids bred for special growing areas, soils, or climatic conditions.
Uses
According to the U.S. Department of Agriculture's Federal Grain Inspection Service (FGIS), there are two categories of dent corn hybrids—yellow and white. Yellow dent corn is produced primarily for animal feed and industrial uses such as ethanol and cooking oils. FGIS identifies that "white food corn hybrids are dent corn... are typically contracted and sold to dry-mill processors and used in alkaline cooking processes for making masa, tortilla chips, snack foods, and grits" as well as producing food-grade starch and paper. Dependent on their starch content, some yellow dent corn hybrids are grown and used in the production of food for human consumption.
