Good question. I think it is mainly to attempt to get a higher yield or an earlier harvest, in spite of the fact that numerous studies have shown that this is, in fact, quite rare. In the US, farmers are also somewhat susceptible to a certain degree of peer pressure. As soon as one farmer in a neighborhood starts, then all his neighbors start getting "itchy" to follow suit. Then their neighbors start, then theirs, etc., until soon everyone in a given area is planting. This is something of a historical leftover from when the planting operation took four to six weeks to complete due to the use of horses and/or small tractors and equipment. US corn farmers are now generally able to complete their planting in about one week per farm, while field conditions allow.
You can, but if they pollinate at the same time, the sweet corn will taste all starchy and not sweet because it crossed with the field corn.
One "cow corn" plant--more properly called field corn--plant will often have two to three ears on it.
The small stalks that appear around the base of the plant are called tillers, or more commonly suckers. They are a genetic remnant of corn's early history as a grass plant. In commercial field corn they have largely been bred out, but sweet corn varieties can show them more frequently. They are harmless and neither add to nor take away from the plant's productivity. Some people remove them, thinking they can help the plant produce more, but I generally recommend against the practice, because it creates an injury site on the plant which can allow diseases to enter.
Current recommendations are to plant corn seed 1.5 to 2 inches deep.
Normally, they build their nest on a corn plant
Livestock corn is known as "Field Corn" Corn for human consumption is known as "Sweet Corn" Livestock corn can also be eaten by humans if it is picked early in it's development; at that point it is known as "roasting ears" The main difference is the size and texture of the kernels. Field corn is larger and tougher to chew, but that also contributes to it's greater ability to be dried and stored for long periods of time

Where I come from, people refer to the cut stalks left in the field after harvesting the corn as the "corn stobs."
They decrease planting time in the field, from the original corn planter, which enabled a farmer to plant one hill of corn at a time, to modern-day planters that plant 70 or more rows of corn at a time, corn planter technology continues to evolve.

Corn was the most important crop to early people because it was plentiful and could be grown easily.
