This book outlines trial-specific yields and individual cultivar disease ratings for spring sown wheat and barley cultivars included in the 2024-2025 CPT trials.
High rainfall across most regions created challenges throughout the 2024-25 growing season, with sowing in some cases delayed until late November. Weather conditions also impacted crop management during the season.
Despite this, spring wheat yields were strong, with Canterbury trials averaging 8.7 t/ha and Feilding 8.4 t/ha, both similar to their respective 4-year averages of 8.6 t/ha and 8.1 t/ha. Notable changes were observed in disease ratings, particularly for Fusarium head blight (FHB).
Barley yields were generally in line with the 4-year regional averages, although a few trials recorded lower results. Changes in disease ratings were noted for scald, leaf rust, and powdery mildew.
