If you can disk and drag, I planted pinto beans last year outside of Gatesville. Cheapest and easy to grow. Bought them at Sam's for $.50/lb in the 50 lb bag, disked the area, slung the beans with a pull behind spreader, and lightly disked over again. Came up great, but my plot was not big enough to keep up with the deer population. I put up an electric fence to try and deter them but it only lasted a couple of weeks. They found them when they were about 6" tall and had the 1 acre plot ate to the ground in a week. 50 lbs to the acre is about the right rate and a little fertilizer to get them going.
