We had turnips in our food plot in our deer pen last year. At first we thought it wasa bunch of mumbo-jumbo that deer love turnips so we started pulling a few out for us to eat. After the first heavyfrost hit they started pawing at the ground to work em out and just devoured em. I dont know why they wait so long but they do in fact love them. It sounds like a good combo choice you have planned. You should keep the deer in the area early season with the beans then once it gets cold its almost a certainty theyll hang around for turnips.
