Dale,
I'm going to tell Chuck to take the bet. Chuck, on an organic farm low
chem input, not a plot. DW sounds like most researchers four plots, four
reps, "fourever". Of course, this is only anecdotal, but I grew a suited
hybrid along side of my OP in a field 1100' X 200 in central Indiana(
right around 5 acres, 1/2 and 1/2) in 36" rows (pop. right around 18).
Yellow blossom sweet clover planted for plowdown in July 97 after wheat
harvest was plowed down late April of 98. Planted May 15 no fertilzer,
no herbicides, no insecticides, and no nothing but a little hope. Only
one rotary hoe and one sweep cultivation because of very wet weather
early. Only .6 rain from July 20 to Sept2. Hybrid yield was 92 bu/acre
at 17% and the OP was 90 bu/acre at 15%. More OP less water, and I
haven't got all the leaners out of my Reed OP which originated in Wis.
Maybe the conditions were a little unusual, but when aren't they.
Later, Rich
