This year we dropped 90k on everything except for one field that we did variable rate on.  In one of our flat rate fields we did a small strip at 40k.  When we combined that strip it averaged just slightly less than the 90k.  Maybe 1 to 2 bu per acre.  There were areas in that 40k population that yielded 78 bu/ac.  We will probably seed around 85k next year and continue to play with variable rate.  I do believe that I need to lower all the rates down on my variable rate fields.  2020 we ranged from 85k - 135k.  I think as a whole most people are planting beans to thick but I am painting with a broad brush when I say that.  We are on 20" rows.
