We see some brome (mountain brome, etc) production for hay out here.

To seed, you can do as Gerald suggests or try to find a drill with a "brome box" -- agitators in the seedbox that keep the seed from bridging above the openers.

Or you could try to broadcast it and use a pasture harrow to rough it in, which is done around here because we grow all hay on irrigated ground. Broadcast, harrow, then turn on the pivot.

Horse buyers will buy it, but you have to sell it. It isn't as easy as something like bloomy alfalfa or timothy, where there is a ready-made demand.
