I cannot find anything that clearly states whether or not planting on public lands is legal or not. However, I would caution you that doing it might end badly for you. Most wildlife agencies are VERY concerned about the spread of nuisance species (both plant and animal) and would surely look down upon planting anything on public use areas.
If you can't get a meaningful answer from a game warden, I would try contacting the WMA biologist and have a conversation with him. The hunting regs list contact info for each WMA. If you are told that you cannot plant, maybe you could convince the biologist to plant millet in the areas you hunt. You might even be able to offer help and he just might plant what you like where you like it.
