End-of-season corn yield forecasts for several locations across the Corn Belt are available at http://cropwatch.unl.edu/2015-Hybrid-Maize-Final-Corn-Yield-Predictions. Predictions indicate above-average grain yield at the majority of locations.
Concerns about stalk lodging in corn persist, as plants with weak stalks are susceptible to lodging if high winds occur before harvest. Fields with poor stalk strength should be near the top of the planned harvest sequence.
In-field drying of corn grain varies with weather conditions, but general guidelines for Minnesota are:
- 0.75 to 1.0 percentage points per day during September 15 to 25
- 0.5 to 0.75 percentage points per day during September 26 to October 5
- 0.25 to 0.5 percentage points per day during October 6 to 15
- 0 to 0.33 percentage points per day after October 15
