Other claims from this paper (6)
- Intervention effect Karamu out yielded Aotea and Arawa by an average of 20% when spring sown, because of better grain set per spikelet and more spikelets per ear.
- Intervention effect Irrigation raised grain yields in all cultivars by increasing tiller survival.
- Intervention effect Sowing at twice conventional rates depressed grain yields in all cultivars by reducing grain set.
- Intervention effect Nitrogen fertilisation lowered grain yields of all cultivars by 7% in unirrigated plots.
- Intervention effect Nitrogen applied at the same rate to irrigated plots increased grain yields by 10%.
- Mechanism The responses support the hypothesis that poor grain set in field wheat is caused by insufficient assimilate supply to the developing ear.
