RR is a Monsanto trademark, other companies have bought some of the patent rights, but I would stay with DeKalb or Asgrow corn and soybeans, and plant the beans in narrow rows, if you have a 30 inch row planter come back and plant the middles, I suggested that to Farm Hunter last year and he tried and had great success with it, he might even plant closer rows this year, try different things see what works....
