When my kids were young, I planted oats and rye grass. I do have a buddy that plants a garden for his deer! Turnips, corn , oats and beans! He kills nice deer every year!! It says a lot for down here!

I tried oats once. Awesome results. Deer would run full speed across a pasture to get to the oats.

That's what I want to hear .

Plant oats to be 6" about for your early seasons, but they will freeze out, buck forage oats hang on longer, Rye will stay green and continue to grow anytime above freezing.

Farmers here plant a lot of rye as a cover crop in the fall, but I don't see much, or any, deer activity on it. Geese seem to prefer wheat instead of rye also..here...

40 lbs oats, 30 lbs wheat, 30 lbs cereal rye. A lb or 2 of red clover and purple top turnips per acre. The deer eat it all

Bob oats are cheap, easy to plant, and easy to get up. They can be drilled in or broadcasted on a rough disked field and still come up.

If one is dealing with a lot deer, they will keep them cropped off nearly indefinitely. If not so many deer, then eventually, they mature and the deer will avoid them. They relish them when they are young and tender and growing. Keeping them cropped off, but not killing them prolongs their success as for as deer
