If you want to plant more than one type of corn per year, then you either have to have a really big acreage and get them far away from each other, or you have to stagger the planting so that they don’t cross.
As to rotation, it goes beyond just planting different variety of corn each year. It means planting different types of crops from one year to the next so that you are not continually planting the same crop in the same place.
The reason for this is to help control pests, and avoid nutrient depletion, as well as bringing nutrients to the soil.
An easy rotation sequence is leaves followed by fruits, followed by roots, followed by legumes:
Lettuce, followed by tomatoes, followed by carrots, followed by beans, for example.
Here’s the article to go with that rotation:

That should be enough to get you started, but don’t get overwhelmed and worry about it. Mainly just concentrate on getting your crop in this year, and where you plant it.
Looks like they did a switcheroo on part of the link:

thanks! You are a wealth of information.
I have so much to learn, but it will just be one season at a time ;)
