We can't seem to figure out what our problem is.  It doesn't seem to matter what we do, unless the soybeans are low yielding, they will not stand.  It makes it a pain to cut.  We've lowered the population to 140K in 15" rows.  They're non-gmo's that get the snot burnt out of them early on which should make them shorter.  They are Pioneer (y-series), E-merge, and Beck's soybeans.  Our bean average the last several years is 60 bu./a.  Ranging from  25-75 bu/a. separate field averages.  The 25 bu beans stood straight as a string.  I know the neighbors surely have good yields, but theirs seem to stand straight.  Would like to figure this out.  We don't over fertilize..  It's bad enough that I had a field I had to harvest one direction; that field average was 67 bu/acre.  Any comments are welcome.  Thanks
