Have had good luck with it except for when I planted Cleopatra. Don't know what happened with it. Had good luck with ryegrass/rape mix, oats/rape mix as well as rye/rape mix. Cows aren't fond of it at first - which is why you plant a sweeter plant with it - but once it gets a frost on it and they get a taste of it - Katie bar the door. Its best to limit feed them on it or force them somehow to take in some dry matter to firm them up but its really good feed. The rape produces a lot too. Even drilled some in a bahia grass pasture and during a drought year had rape at the first of July. I was well pleased with it. If you plan on planting millet you can stagger this planting by allowing the rape to grow longer in the year which will prevent you from having all the millet coming in at the same time.
