Factors affecting corn yields
1978
Butell, R. | Naive, J.J.
Among the more important factors affecting corn yields are weather, fertilizer use, technology, and planted acreage. when removing the corn blight of 1970 from the analysis, these variables used in multiple regression analysis explain about 96 percent of the variation in U.S. corn yields during the period 1954-1977. expanded use of nitrogen and other production technology have strongly influenced growth in yields while expansion into less productive acreage has tempered yields in recent years.
