Post-Harvest Hard Wheat Performance Evaluation

A post-harvest assessment of grain yield, protein and test weight by field or zone within the field can help you evaluate what went wrong (or right) during the crop year and inform your plans for next year. Post-harvest evaluations can also give you important insights into field conditions such as residual soil nitrogen that may impact the crop next year. Refer to the matrix below of grain yield-grain protein outcomes. Click on a cell to learn more about the outcome and what it means in terms of environmental conditions and/or management practices.
