David,

I assume you mean rye, and not rye grass. Both rye and rye grass grow in a wide range of conditions. Deer will consume both, especially if they are heavily fertilized! However, both will readily choke out other crops mixed with them, especially clovers during the spring. Rye grass readily produces seeds that last a long time and will germinate the following year (or years) which can cause unwanted competition for future crops planted in the same plot. Deer seem to prefer wheat as much or more than rye or rye grass. As there are fewer negative characteristics with wheat, I prefer to plant winter wheat as my small grain crop.

Growing Deer together,

Grant
