Farmers are planting soybeans earlier than normally recommended - is this trend producing higher yields? Private industry planting date data is available but recent university-based data is very limited. Will early planting in no-till tend to reduce plant stands and yield, due to less than desirable soil conditions or disease? Will starter P aid establishment of early-planted soybean in either tillage system? NDSU recommends broadcast P as the best choice for yield response, but this is based on Midwest research, with currently limited ND data. The issue of fungicides for plant health needs to be examined as a production management strategy.
This preliminary database would indicate a potential yield and economic advantage by using the combination of early planting, direct seed system, broadcast application of fertilizer and foliar fungicide.
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.
