Subject: RE: UNL's corn yield model



Centre county Pennsylvania, USA
I think UNL's corn yield model has one big plus that nearly all other models are missing. It uses local weather station data as it's only weather input, none of the radar or satellite data (WAGS) that many other yield models use.

Estimating harvest yield from any model is problematic. Models are not validated for future data. The value of a model like UNL's HybridMaize model is that it does provide a relatively good estimate of yield potential for the current year to date (only), not a projection of harvest yield.

User manual for UNL's HybridMaize model provides significant detail of this model, including all the caveats that can, and often do, wreck harvest yield.
