How much corn can grow on one stalk?
I want to know about how much corn I should grow.

I did a google search on your question. Here's the answer. Definitely read up on growing corn as it is very tricky regarding pollination.

"Ear number and size can vary greatly from cultivar to cultivar. Most sweet corn varieties will have one to two ears per plant because they are mature rapidly and are generally short statured plants."

Ok, thank you I will defiantly read up on that.
