Difference Between Corn and Milo

Difference Between Corn and Milo

Corn (maize) and milo (grain sorghum) are both important cereal grains used for animal feed, human consumption, and biofuel production. While they may share some similarities, there are key differences in their plant characteristics, growth habits, and harvesting considerations that are important for farmers and equipment operators to recognize.

From a botanical and morphological standpoint, the plants are distinct. A corn plant has a tall, single stalk with long, broad leaves and produces one or two large ears located at the nodes. The ear is covered by a husk, and the kernels grow on a central cob. In contrast, a sorghum plant is generally shorter and bushier, with more leaves and a central stem that terminates in a single panicle, or seed head, where the small, round grains are clustered. This seed head can be compact or open, depending on the variety.

Their growth requirements and adaptations differ significantly. Corn typically requires more water and fertile soil to achieve its high yield potential. It is often considered a more input-intensive crop. Sorghum, on the other hand, is renowned for its drought tolerance and ability to thrive in poorer soils with less water. It has a more efficient root system and waxy leaf coating that helps reduce water loss, making it a reliable crop in arid regions.

These physical differences directly impact harvesting practices and machine settings. The primary difference is the header used on the combine. Corn is harvested with a row-specific corn head that snaps the ear off the stalk. Sorghum is harvested using a grain platform header, similar to what is used for wheat or soybeans, which cuts the entire seed head off the stalk.

Furthermore, the settings on the combine must be adjusted for the different crop characteristics. Sorghum grains are smaller and harder than corn kernels but are encased in a glume that can be tough to thresh. Therefore, combine cylinder/rotor speed and concaves clearance need to be carefully adjusted to thresh the grain effectively without cracking it or creating excess fine material. The fan speed on the cleaning shoe may also need to be reduced for sorghum, as its lighter grains can be easily blown out with the chaff if the air velocity is too high.

In summary, while both are valuable grains, corn and sorghum differ in plant structure, environmental needs, and the specific harvesting techniques required to bring them in from the field efficiently.
