Boldfaced numbers are within confidence interval at specific locations and combined years of yield data.
* Location was affected by a Wheat Streak Mosaic Virus infestation, which resulted in reduced yield of susceptible varieties.
Locations
2024 — Crook and Julesburg, CO; Ingalls, KS
2025 — Crook, Julesburg, and Yuma, CO
2026 — Crook, Julesburg, and Yuma, CO
2026 Notes
Crook, CO — Very low yields, but that matched the region. Well established, but little to no moisture throughout the spring
Julesburg, CO — Low yields, but better than expected in late spring. Heavy freeze basically killed all fall tillers so yields are almost exclusively from spring tillers.
Yuma, CO — Low yields impacted by drought, but also heavy freeze damage. Late lines favored by late precipitation.
