Which of the following is classified as a coarse grain?

Corn is classified as a coarse grain due to its large seed size and high starch content, which categorize it among grains that are generally used for livestock feed or for products like cornmeal and corn syrup. Coarse grains include crops that are typically higher in fiber and lower in protein compared to other grains, which makes them particularly suitable for bulk feeding.

In contrast, wheat and barley are generally classified as fine grains or cereal grains, focusing more on flour production or malting processes, which require a different size and composition. Rye also falls into the category of a cereal grain primarily used for baking and distillation. Corn’s robust size and versatility make it the definitive example of a coarse grain within agricultural classifications.
