I've heard deer don't like grain sorghum until the heads change color and then they'll wipe it clean. I've wanted to try sorghum because it will stay standing until the 2nd season.

Another option to consider is buckwheat. One source I read says it matures in about 60 days and it's such a prolific reseeder that you can get a 2nd and 3rd crop just by disking the field after it has dropped its seed. One key to getting doves to use your property is giving them something to eat on a continual basis. Most dove fields don't provide much until the week before opening day. You may see more if you provide a constant food source for them, like 3 separate crops of buckwheat.
