Fertilizer use and weather effects on corn and soybean yields
1985
Teigen, L.
Extract: Yield equations were estimated for corn and soybeans which incorporated information on planted acreage, weather, trend yield effects, and fertilizer application rates derived from the SRS objective yield surveys. The corn and soybean yield forecasts made in July 1984 differed from the August 1984 Crop Production yield estimates by less than 0.6 standard errors of forecast. The odds against such performance occurring by chance are substantial.
