Notes: Grain yield and protein concentration were adjusted to 12% moisture content. a: Shaded values are not statistically different from the highest value within a column. * Two-year means were calculated using data from 2023–2024 and 2025–2026. ** Three-year means were calculated using data from 2022-2023, 2023–2024 and 2025–2026. Trial data were not available for the 2024–2025 growing season. Varieties LCS Gaucho CL+, OK21DTR1722-16W, WB4347, and WB4792 were excluded from the intensive management trial analysis due to severe freeze injury, which was more severe on the west side of the trial. OK Corral was excluded from the analysis due to deer damage. Double-dashes "--"=data not available.
