In the whole country, it varies by year. For a given farm, it's based on acreage, weather, and more.
Large government subsidies.
Corn is the foundation of their feed.
Sweet corn and all corn that we use commercially is annual, and must be replanted every year. There are varieties that have been crossed with Zea Teosinte (a wild relative of corn/maize native to Mexico) that are perennial. However, these crosses do not produce near as much as annual corn by nature of being perennial. They put much more effort into their root systems and store much of their energy in rhizomes for use the following year. They have been known to live 3 years or more.
Corn grown for alcohol. This is because alcohol production is artificially stimulated by tax subsidies. Without the subsidies, alcohol from corn would not be economical, and even WITH the subsidies, is only marginally economical. The problem is that it takes almost as much oil to grow and harvest the corn and turn it into alcohol as the energy from the alcohol itself produces. Diverting corn from food to fuel causes its own economic inefficiencies, by (for example) raising the cost of beef or pork, or raising the cost of the corn itself which is a dietary staple for many people. Hamburgers and tortillas are both more expensive than they ought to be because we're putting corn in our gas tanks rather than our mouths.
Certain species of corn need more water than others to grow well. The average corn plant needs several annual inches of rain to grown effectively.
Corn is a subsidized crop in the US. This makes corn a very cheap crop for farmers to produce, that is why there is so much of it (see its use as a sweetner -HFCS, and Ethanol). Tax subsidies are granted to farmers from tax dollars that US citizens pay, so the answer to your question may be both taxed and subsidized but the more relevant answer is that corn is a subsidized crop.
The point where supply matches demand (assuming that there are no government subsidies, tariffs or taxes which would then have to be taken into consideration).
Corn subsidies can be seen as both good and bad, depending on the perspective. On one hand, they support farmers, stabilize prices, and promote food security; on the other hand, they can lead to overproduction, environmental degradation, and contribute to unhealthy diets through the promotion of high-fructose corn syrup and processed foods. Ultimately, the effectiveness and impact of these subsidies depend on how they are managed and their broader economic and environmental implications.
Because the government pays for a huge portion of American health care, it feels it must snoop, control, cajole, and manipulate the population. The government doesn't seem to really care that much about obesity, though. If it did, wouldn't it cut subsidies to corn farmers whose product goes to make corn syrup?

The annual salary of a governor in Nigeria is 1.9 million naira. One Nigerian naira equals 0.0062 US dollar. In addition to a salary, the governor receives many different types of subsidies and benefits.
Farmers generally support biofuel subsidies as they can provide a stable market for their crops, particularly corn and soybeans, which are commonly used in biofuel production. These subsidies can enhance their income and promote rural economic growth. However, opinions can vary; some farmers may be concerned about potential environmental impacts or market fluctuations caused by increased biofuel demand. Overall, many see subsidies as beneficial for their livelihoods and the agricultural sector.
