Be curious to know where you're seeing later beans move North. I would say the overall industry trend is the opposite and most folks have moved half to a full maturity group earlier.
Not where I’m at on the MN border. Used to be 1.5-1.9. Now 2.3-2.5 beans. 103 corn used to be the late stuff, now 108-110 is common. 103 is the early stuff.
Yep and the Southern third of IA is planting mid 3's.
