What’s the deal with variable corn yields?

Farm Progress agronomist Mike Witt explains that corn yields varied widely within individual fields in 2017 due to drought, floods, heat and cold planting conditions. He advises farmers to evaluate hybrid performance field by field rather than by farm averages.

WHY IT MATTERS

Yield variability is an agronomic advisory point with little direct price effect, since the harvest-level picture is already captured in USDA estimates.
