- Method / resource Logistic curves represented whole-plant dry weight from emergence to harvest.
- Method / resource Logistic curves represented bulb plus sheath dry weight from emergence to harvest.
- Method / resource Meteorological variables replacing time still gave good logistic fits.
- Observation Accumulated day-degrees reduced but did not eliminate between-site and between-season growth differences.
- Observation Accumulated sun-hours did not eliminate site or season differences in whole-plant dry weight.
- Association Within-season site differences agreed with observed density at harvest.
- Observation Total leaf dry weight reached a maximum and then declined.
- Method / resource Accumulated sun-hours described leaf dry-weight relationships in only one season.
