Something to keep in mind is many Wheat varieties don't need to be planted, they dig themselves in if the soil isn't solid compact. Rye is also pretty much throw and grow. I've planted Oats in the fall and the winter kill plant matter makes a nice bed for Oats and Wheat in the spring. Deer will feed on the winter killed Oat stalks.

Just an idea, plant the depth sensitive seeds first, them broadcast the Wheat and Rye last. Birds may be a problem.

I've always planted Clover as a stand alone plot. The soil where I plant needs a lot of Lyme for Clover to thrive. The Wheat, Oats and Rye not so much.

I often plant patches in a larger plot. Most plants tolerate their own kind, mixed plots can be iffy. Or research a little to find out which plants grow well together and which don't.
