- Method / resource Late-season NG best estimated corn yield in 2003, with r2 of 0.632.
- Method / resource Late-season NG best estimated soybean yield in 2003, with r2 of 0.467.
- Method / resource Multiple-band stepwise regression explained similar yield variation.
- Method / resource Corn yield variability was modeled better than soybean yield variability.
- Method / resource Remote-sensing yield estimates were poorer in 2004 under adequate moisture, with r2 below 0.3.
