National soybean yields have increased from 11 bu/acre to 43 bu per acre over the past 90 years with an average gain of 0.34 bu per acre per year. These yield gains are attributed to advances in genetics, pest control, and production practices. Breeding efforts usually receive the greatest credit to the yield gain rate with little attention to agronomic management. Future soybean production necessitates a greater rate of yield gain to meet exponentially growing demands. The research aims to understand the advances in agronomic management and soybean breeding over the past nine decades. The overall goal is to improve future production practices and breeding efforts of soybean based...
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
