South central Minnesota | In some Cornbelt fields, the crop is just pollinating and is far from being able to be shelled for weighing. In those cases “All unharvested samples in maturities 1 and 2 (no ear shoots and pre-blister stage) use a 5-year historical average ear weight. Maturities 3-6 (blister through dent stage) employ models derived using kernel row length and ear diameter. Enumerator harvested samples use the average field weight per ear, shelled grain weight per ear, and the moisture content to estimate the grain weight per ear at 15.5 percent moisture.”
Ok what percent of the crop will fall under maturities 1 and 2? | |

One last time on ear weights
