German or Foxtail Millet has low water use and crude protein of the hay might be around 15%.  We have German “R” strain millet.  It can provide a quick hay/forage crop with excellent feed quality when put up in a timely manner.  For cover crop uses, some may prefer it because it doesn’t create as much biomass as some other options may.  This could work well with some cowpeas, mungbeans or other legumes between wheat harvest and planting.
