I agree w/you that corn is a favorite of mine also to grow. I grow for the taste and fresh corn is just spectacular tasting.
Also, your thoughts on the importance of rotation are spot on. Beans are great to use in that rotation sequence for corn...however you may hear from the local cynic decrying nitrogen fixing as an "Urban Myth". Soil tests on my dirt prove without a shadow of doubt that Nitrogen fixing is NOT an "urban myth".
Your planting is good but a couple things I've learned over the years enhance production. 1) its important to use raised rows here in East Texas. Otherwise, our annual spring rains can easily drown the seedlings. 2) it is critical for small plots of corn to reach the pollination stage at the identical same time, hence careful planting at the same depths and identical seed placement are important to assist this. Corn seed has a blunt or rounded end and a pointed end. To help ensure germination at the same time I always plant each seed the same way.
My corn is now tasseling and we are eagerly anticipating the taste of that wonderful fresh garden sweet corn.
