NW Missouri | Yes, in our area there is no corn on corn - everyone is either 50/50 or they plant more beans than corn. On bottom ground where we don't have to worry about erosion, we could plant beans for several years in a row if we wanted to I guess. But like I said, we do like to mix up the chemicals (we plant ru corn, and liberty beans), and I know SCN resistance is supposed to be getting worse, even though we haven't noticed it yet, so we generally try to keep it on a rotation of 2 years of beans to 1 year of corn. And some ground ends up being closer to a 50/50 rotation. On hill ground, we always try to put a cover crop between the two years of beans. We don't much tillage unless there's a good reason.
