Check out Stratton seed forage beans. They are round up tolerant. I planted them for the second year this year. They did good for me last year. Withstood pretty heavy browse in my 1/4 backyard plot and better than traditional ag beans side by side in the same plot.
I did see them on a farm side by side with eagle beans. The eagle probably grew a little taller in the end. Stratton still did just fine but also ended up with a few more pods in my opinion.
Stratton beans are about 1/2 the price of eagle. For comparable performance, it’s not even a question for me. Your results may vary.
