I agree with ewest. I can't speak to baiting laws in other states, but here in CA it's any attempt to make the crop more available to waterfowl. Planting a crop is not illegal. Flooding and hunting over this crop is also not illegal. Running your 4 wheeler over the unharvested crop, "accidentally" mowing a portion of the crop are both illegal here.
I should have mentioned earlier but if the crop is naturalized (eg. volunteer from the natural seed bank) then you can manipulate it any way you prefer (mowing, disking, etc).
This is why we recommend managing for smartweed and watergrass (Echinocloa crus-galli) rather than the cultivated varieties of millet. This is because of their superior ability to volunteer from year to year. You'll never get a seed companies to recommend a naturalized watergrass or smartweed over a cultivated millet as this is bad for business.
Back to the batiting issue, this is the situation here in CA, so be sure to check your local state game agency.
