You mean like this...Elbon Rye 10-23-07
Rye seed is about the size of wheat, a little smaller. Ryegrass seed is very small. The difference is that there is ryegrass between the drilled rye in the picture. The larger seed has more food for the seedling which get the rye up and going a lot faster that the ryegrass...gets you grazing sooner. Another advantage of rye is that it grows at colder temperatures than any other cool season annual...if temps get above 35 degrees F and the sun shines, rye will grow some while ryegrass just sits there. Now the drawback to rye...it doesn't like wet feet. Too much rain will kill it, even on well drained sandy soil types if the rain persist too long. Where ever water stands in your pasture it will die. Obviously this hasn't been a problem for us in the Southeast the past few years. Rye will start heading out in March with low fertility and/or warm weather. These drawbacks are why I plant ryegrass with the rye. Ryegrass doesn't suffer the water problems and can grow into June under the right conditions. The mix makes a good, consistent winter pasture. Rye will also establish better if you are sod seeding.
Hope this helps. :wink:
