I've done cowpea's, sunflower,millet and milo this way, but hands down the best in Buckwheat. You can triple crop it, it produces a lot of P for your soil and deer eat it, but don't destroy it. Good for turkeys and the bee's love it when it flowers. Once it goes to seed, cut it and it will reseed itself and grow back. Free seed! Who doesn't like that? Dove also like it. You can mix in millet if you like or cowpea's or sunflowers.
