Your corn at Cedar Flat (the Osborne tract — 557 acres, planted April 10) has accumulated about 1,651 GDUs through June 29 (the latest weather on record).

That puts it right around R2 (blister) — early grain fill. Reference markers for corn (base 50/cap 86):

Silking (R1): ~1,400 GDU

Blister (R2): ~1,660 GDU ← you're here

Milk (R3): ~1,925 GDU

So the crop has tasseled and silked and just moved into filling kernels. Kernels are being set now — this is a yield-critical window where moisture stress hurts most.

Two caveats: the GDU-to-stage mapping is a rule of thumb and shifts with hybrid maturity, so confirm against a field scout if you need it exact. Also note the other Cedar Flat tract (Nash) is in soybeans this year, not corn — this answer is just the Osborne corn.
