Other claims from this paper (13)
- Association The Leafy hybrid had more leaf area per plant, 20 to 25% above the conventional hybrid
- Association The Leafy hybrid produced significantly greater silage dry matter than the conventional hybrid
- Association The Leafy hybrid had a significantly smaller grain yield than the conventional hybrid
- Intervention effect High density and low N stresses resulted in more barren plants in the Leafy hybrid than in the conventional hybrid, up to 15%
- Intervention effect High density and low N stresses lowered harvest index in the Leafy hybrid relative to the conventional hybrid
- Intervention effect The Leafy hybrid was more sensitive than the conventional hybrid to high density and low N stresses
- Intervention effect High density and low N stresses lowered grain yield in the Leafy hybrid relative to the conventional hybrid in 2003
- Intervention effect Grain yield was maximal at 225 kg N ha −1, ahead of 75 and 150 kg N ha −1
- Intervention effect Silage dry matter did not differ between 150 and 225 kg N ha −1
- Intervention effect Plant population density had no effect on grain yield
- Intervention effect Silage yield increased linearly as plant population density rose from 60 000 to 90 000 plants ha −1
- Association Within the tested population density range, the two hybrids showed no differential response in grain yield or silage dry matter
- Recommendation The optimum plant population density for silage production may lie beyond 90 000 plants ha −1 for both hybrid types
