Has anyone planted emerge non gmo beans. Thoughts on yield. 3.7 maturity.

I planted them for an elevator in central Illinois about 6-years ago- non GMO too. I was getting paid a $2.00 per bushel premium. The Emerg beans I had were very viney and only yielded about 48 bushels. They yielded about 20 bushel less than what my Liberty beans yielded that year. I even had more chemical cost in them because they were non-GMO. It was not a profitable experience for me. But you may have better luck.
