The objective of the research has been to determine if traditional weed management practices used in soybean are less profitable for growers as soybean seeding rate recommendations are reduced to 140,000 seeds/acre or less. The weed control tactics have ranged from using a soil residual herbicide followed by a post emergence (POST) herbicide to progressively later POST application timings in a total POST system. Results to date have shown the influence of weed management practice on optimal seeding rate varied by geographic location. Due to the dependence of environment and geography on the weed-soybean interaction further field research is justified to validate the previous results and...
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.
