2021 Orthman Research Yield Book


Nutrient Use Efficiency by Hybrid As a whole we are happy with the nutrient use efficiency. However, there is always room for improvement. Personally, we need to lower the average NUE for nitrogen closer to the 0.70 lbs. N/bu. We will be adjusting N timing for 2022 in order to drive that improvement. Since the farm was in single digit P values when we started working, we have been over applying P in an effort to raise P values. The 92 day hybrid P9211Q was planted with the intentions of creating a demonstration area for the field day but later we decided to take it to yield. We should have adjusted nutrient application for yield goals to make it a more efficient hybrid.
