  3. Corn Yield Forecasts as of August 2, 2023

    Author(s): Osler Ortez

    Most of the corn acreage in Ohio now should have reached the silking stage, except for delayed planting conditions. Some fields have already transitioned to dough and milk stages. A new simulation of 2023 end-of-season corn yield potential and crop staging was performed on August 2, using the UNL Hybrid-Maize crop model in collaboration with faculty and extension educators from 10 universities.
