2026 Notes
Agar, SD -— Extremely good yield, especially with the overall limited precipitation. Stands were not perfect due to planting into spring wheat
residue, but data was clean nonetheless.
Presho, SD — Good yield despite drought stress showing at times and some noticeable freeze damage. Similar to Agar, stands were
impacted by planting into spring wheat residue.
