- Association Environment, genotype and nitrogen treatment interacted significantly for grain yield.
- Association The three-way interaction was significant for biomass yield.
- Association The three-way interaction was significant for harvest index.
- Association The three-way interaction was significant for partial factor productivity.
- Association The three-way interaction was significant for nitrogen agronomic use efficiencies.

- Observation Landraces had 11% higher biomass yield than improved genotypes.
- Intervention effect Partial factor productivity fell by an average of 65% at high nitrogen fertilisation.
- Observation Improved genotypes showed 10% prevalence in partial factor productivity.
- Observation Landraces tended to promote vegetative growth.
- Observation Grain filling efficiency was higher for improved genotypes.
