Key Differences
Corn, known scientifically as Zea mays, is a cereal grain with a large cob from which kernels are harvested. Millet refers to small-seeded grasses that are harvested as grains in various species, such as pearl millet, foxtail millet, and proso millet.
Corn is a staple food in many parts of the world and is used in a variety of products, including cornmeal, corn syrup, and corn oil. Millet, on the other hand, is often used in bird seed and as a traditional grain in some developing countries, although it is gaining popularity as a health food.
One key difference between corn and millet is that corn is grown as a mono-cropped annual, requiring a significant amount of water and fertilizer. Millet is more drought-tolerant, can be grown in harsh environments, and is commonly used in crop rotation systems due to its ability to improve soil health.
Corn is typically yellow but can come in a variety of other colors, such as white, red, and blue. Millet grains are generally small and can be white, gray, yellow, or red. The nutritional content also differs, with corn being high in carbohydrates and millet being high in fiber and protein.
While corn is often genetically modified to increase yield and resistance to pests, millet is largely non-GMO, which makes it appealing to those looking for organic or traditional food options. Both grains can be popped like popcorn, but popped millet is much smaller in size compared to corn.
