In recent years, some agronomists working with crop production, and a number of our leading producers have expressed concern about our having reached a "yield plateau" or barrier to higher yields. Part of this concern springs from the belief that we may have reached an upper limit to yields, especially with corn and soybeans under prevailing moisture and temperature conditions and with the present set of production practices and varieties. Consequently, a number of outstanding crop and soil scientists were invited to participate in a symposium on the theme "Moving Off The Yield Plateau." A prerequisite to their selection was that they be on the "leading edge" of research in specific fields and/or have the background and astuteness to see implications or applications of highly isolated or highly specialized findings to improved crop production practices. The topics included range from growth substances, genetics, and plant physiology to soil fertility, cultural practices, crop protection, and systems integration.
