I had good luck with 1 acre of corn last year, but I have fairly low deer density and I wouldnt want corn in a timber plot anyway.
In your situation I think I'd heavily broadcast RR beans in the spring, then till them under in August and go with oats/rye or WW/rye. Both would be easy, cheap, should help control the weeds, and the beans would help provide some nitrogen for your cereal grains.
