Dont you believe small plots wont attract derr. deer are browsers and if they know some succulent browse is available they will come. Wont keep them there because unlike cattle (grazers), deer are browsers and like to move around. I would suggest you try Trifon, a turnip like plant. Deer and turkey love it. True if you plant stuff like cow peas, soybeans, deer will eat all of the greenery before it yields beans
