I'm a farmer AND a food plot planter. Broadcasting turnips, radishes, and rape in standing beans works beautifully. However, I've only done it in a food plot and not my field beans. I'll give a farmers' perspective here. If you seed stuff in the middle of a bean field and it grows like you want it to, when the combine hits that stuff, it's going to put a whole bunch of wet, green stuff thru the combine with the dry beans, NOT GOOD. I could see a farmer getting very pizzed off. A little along a field edge probably won't hurt but an acre of it in the middle of an otherwise dry crop of soybeans may send you looking for a new place to hunt. BE CAREFUL!!
