Wheat and oats have several advantages. One is they are reasonably easy to establish, and two is they are non-invasive. And as far as attracting deer and providing nutrients, they do about as good a job as anything. Given a little rain and a little fertilizer, and they will thrive as well as anything.

Doing some range reseedings, I have gotten a decent response from Illinois bundleflower and hairy vetch. I don't get enough rainfall for most clovers.
