I am working with a hay grower in central NC trying to eliminate bermuda from a field he'd like to grow orchardgrass in. What we've done in the past to eliminate common bermuda before plantin a hybrid, is to plant soybeans for two years which starves and shades out the b'brass. I'm hoping you've had success in maintaining both alfalfa and b'grass in the same field because of the wide row width on the alfalfa? We've planted RR alfalfa in about 4 inch rows and are hoping between the roundup and the shading and no N applications, that we can eradicate the b'grass before the alfalfa thins out too much to be strong competition...any thoughts from anyone?
