- Association Plant density was negatively related to seed yield per plant.
- Association Seed yield per area plateaued across the density range.
- Observation The optimum density for Grasslands Nui was 300 to 400 plants/m.
- Observation The optimum density for Grasslands Matua was 100 to I30 plants/m.
- Intervention effect Nitrogen increased seed yields regardless of application time.
- Observation Nitrogen was most efficient just after stem elongation commenced.
- Intervention effect Grazing reduced grass seed yields.
- Intervention effect Grazing negatively affected seedhead size and individual seed weights.
