advice on Rye grass

Hi,,

I currently use barley as a nurse crop when sowing my fields down to timothy & alfalfa . I don't have a very market for the barley, so i was looking to replace the barley with another crop. Ive never planted rye grass, but a salesman told me it would make a good nurse crop?? Has anyone tried this? Does much of the rye grass come up a 2nd time ?
