Brief Project Summary:

The goal of this project is to quantify light capture, nitrogen uptake, and water use requirements of soybean in
highly productive producer fields where crops yields approach their potential.

Project Deliverables

We expect the output of this research to confirm that it is possible to achieve yields near 90 bu/acre
in production-scale fields in Nebraska and identify what is needed by the crop, in terms of managing the
available light (planting date and variety maturity), water (irrigation timing and amount), and nitrogen N uptake,
biomass N and seed N content (i.e., seed protein), to achieve such high yield levels. This research will also be
relevant for increasing yields under dryland conditions because both irrigated and dryland yields are driven by the
same biophysical factors (water, nitrogen and light). We believe that it is important that the on-farm sites are
irrigated to be able to erase yield variability due to year-to-year difference in seasonal rainfall.

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.
