Count an ear.
Estimate the field.
Photo the ear, let AI count rows and kernels, then enter ears in 1/1000 acre and grain fill. Same yield-component method used in Nebraska fields.

Kernels/ear = 16 × 42 = 672
30 ears × 672 ÷ 85 = 237 bu/ac
Yield component method. Typical band ±15–25 bu/ac with several random spots.
