southern MN | We try to plant enogh seeds per acre (around 30,000 per acre 'here', depends on moisture typically available) so that only one ear forms per plant. This is typically the best yield. It is not uncommon to see a 2nd ear around now on a lot of plants, but often it stays very small and does not turn into anything.
If you plant less seeds per acre but have lots of fertility, each plant will use the extra sunshine & nutrients to make a 2nd or 3rd ear. But - that typically makes smaller ears with less corn per acre.
If you plant corn too thick, then it becomes weak & wants to fall over & again the ears become small & less corn per acre.
A goal of corn planting is to get the right plant population per acre so only one ear forms per stalk, and each ear is pretty big and filled out with kernals almost all the way to the tip. Takes very evenly spaced corn and the proper weather for that to work out just right.

How many ears per plant?
