- Association The nitrogen by environment interaction was not significant.
- Association The nitrogen by genotype interaction was not significant.
- Intervention effect Higher nitrogen rates generally raised wheat yield, with crossover effects across environments.
- Intervention effect In some environments, higher nitrogen rates lowered wheat yield.
- Mechanism Higher nitrogen rates exacerbated Fusarium head blight or foliar diseases in some environments.
- Association Two wheat cultivars yielded well in most environments but very poorly in two with severe Fusarium head blight.
- Recommendation Fusarium head blight resistance was highlighted as important to spring wheat production in eastern Canada.
- Method / resource The environment by factor biplot effectively revealed relations among environmental factors.
- Method / resource The environment by factor biplot effectively revealed weather and soil patterns.
