Other claims from this paper (8)

Intervention effect Uneven machine planting reduced wheat yield by 20% compared with evenly spaced plants under postanthesis water deficits.
Intervention effect Yield of irrigated wheat was not reduced by uneven planting.
Intervention effect Wheat at high densities developed lower leaf and ear water potentials than at low densities during postanthesis water deficits.
Intervention effect The greater postanthesis water deficits did not reduce wheat yields.
Intervention effect Grain yields at 25 and 50 plants per square meter were lower than at 200 plants per square meter when postanthesis water deficits developed.
Intervention effect Later-formed tillers, produced only at low densities, had smaller thousand-grain weights than the mainstem and first tiller under water deficit.
Observation Anthesis was delayed by up to 20 days in later-formed tillers of wheat.
Observation Grain fill occurred at low leaf and ear water potentials in wheat.
