They can't "regrow" from the same leaf node, but other leaf nodes can occasionally produce another ear. It won't be very big, and probably won't have much corn on it, though.
I'm definitely not an expert, but from what I understand you can cut them down as soon as you harvest the corn. The stalk will not continue to produce as some other plants do. Once you harvest the existing ears of corn, the stalks are done. I just read a cute idea about saving the cut stalks and bundling them together for a fall / Halloween decoration :)
A Crop Sweeper is the best way to pick up down corn. It can be found at www.cropsweeper.com.
growth and development
A farm implement that pulls the ears of corn from the stalks and husks. The ears are then passed through a "sheller" which strips the kernels from the cobs. Improvements to the combine (often called a 'harvester") do the jobs of both the picker and sheller with the same machine that is used to harvest wheat and sorghum crops. But, in some specialized farms producing hybrid seed corn, a person will be gathering the ears by hand, so his job description is probably "corn-picker".
The number of ears of corn in a bushel depends on the size of the ears of corn. On average, about 40 to 60 ears of corn are in a bushel.
