Acutally a clover mix is usually the best for a foodplot. Red Clover for quick growth, Ladino for taste and plot longevity, and Dutch white clover as a low growing type for when deer hit the Red and Ladino hard. A third of each will give you a great clover plot. Buy from a local mill, no need for the expensive deer mixes.

Most importantly for a clover plot is to lime and fertilize just as a farmer would for alfalfa. Get the PH above 6, no nitrogen, a little phosphorus, and lot of potassium. A good soil test will tell you exactly what you need, and is the first place to start.
