I’m a fan of rye after the silage corn gets cut. It grows easy, cheap and the deer like it! If I was starting one in the spring, I would do buckwheat in the spring, mow it, spray it, disk it in and plant rye and red clover last week in August
I have 12 acres of rye/vetch and two acres of standing corn on my farm. It’s great to see all types of wildlife using it.
Good luck!
