Corn is a staple food across the globe.

Corn has become the most common food consumed in many parts of the world and mostly the standard diet of the people. The production of corn even surpassed rice and wheat.

Humans don't directly consume most of the corn per se.

On the other hand, despite the huge production of corn, only a small portion goes directly to people. The large portion of corn is used for animal consumption, for corn ethanol, and other corn products such as corn oil, corn syrup, and corn starch.

Corns have six major types of corn.

In detail, the six types are sweet corn, dent corn, pod corn, flour corn, flint corn, and popcorn.

Dent corn's name comes from the indentation of its kernel when ripe.

The dent corn got its name because it develops an indentation at the crown of each kernel when it’s ripe. Dent corn such as Reid’s yellow dent corn, white dent corn, and yellow dent corn are varieties of field corn that have high soft starch content.

Sweet corn is a low-starch corn variety.

Sweet corn or “sugar corn” is a variety of corn with high sugar content and has low starch. The sweetness of the corn is the effect of an inactive mutation in its genes that restrains the transformation of sugar to starch in the endosperm of the corn kernel.

Flint corns are a hard and colorful variety of corn.

Flint corns (also known as calico corn or Indian corn) have hard kernels that come with different kinds of colors. Each kernel has a hard exterior layer similar to a stone or flint and it protects the soft endosperm.

The unique appearance of the pod corn is due to a mutation.

Pod corn (also known as “wild corn”) isn’t a wild ancestor of corn. It is a mutation of corn that develops leaves that cover each kernel. The fine case that looks like a thin paper when dried makes the appearance of this corn variety very unique.

Flour corn's primary use is for cornmeal and cornflour.

This variety of corn has soft starchy endosperm. The soft starchy composition of this corn makes it easy to grind into finer cornmeal compare to other similar types. Moreover, flour corn one of the most commonly planted in the southwest region of the United States

There are many ways to use corn aside from being food.

The corn’s secondary products are found in various non-food items such as cosmetics, laundry detergent, soap, aspirin, antibiotics, rust preventatives, glue, paint, dyes, fireworks, shoe polish, ink, and plastic productions. Definitely some useful corn facts here!

The sweetcorn was measured on December 22, 2011, from a horizontal position at the bottom of the botanical shoot to the top of the tassel.

The early corn plants are small and can only have one corn per plant.

The early corn plants are very small. During those days, corn ears grew more or less an inch long and only one per plant. According to studies, it was the hybridization and crossbreeding of the American indigenous people that contributed to the capability of growing several corn cobs per plant.

Corns can take between 60 to 100 days to reach harvest.

In general, corns can take between 60 to 100 days to reach harvest depending on its variety and the volume of heat during the growing season. Furthermore, since corn is cold-intolerant, they are planted during the spring season in the temperate zones (places with four seasonal changes such as the United States).

Kernels, husk, stalk, silk, roots, and tassel are the major parts of the corn.

Here are some of the most important terms of the corn. Kernels (the plant’s seed and the part that is eaten), husk (the tightly-wrapped leaves that cover the ear of corn), stalk (the stem of a corn plant), silk (the long soft threads at the top of the ear of corn), tassel (the flower at the very top of the plant), and of course the roots which carry food and water to the corn plant when they are still planted.
