Other claims from this paper (14)
- Intervention effect Shoot nitrogen content rose with nitrogen rate.
- Intervention effect Bulb nitrogen content rose with nitrogen rate.
- Intervention effect Bolting incidence declined as nitrogen rate rose to 197 kg per hectare.
- Observation Pegasus had among the highest bolting incidence.
- Intervention effect The percentage of decayed bulbs rose with nitrogen rate.
- Intervention effect Total yield at the lowest nitrogen rate was lower than at higher rates.
- Intervention effect Marketable yield at the lowest nitrogen rate was lower than at higher rates.
- Intervention effect At rates at least 145 kg per hectare, total yield had no significant rate response.
- Intervention effect At rates at least 145 kg per hectare, marketable yield had no significant rate response.
- Observation Bolting and decay were the main combined sources of marketable yield loss.
- Observation Marketable yield losses were minimized at 162 kg per hectare nitrogen.
- Observation Low nitrogen yield losses were mostly due to bolting.
- Observation High nitrogen yield losses were mostly due to decay.
- Recommendation Excess nitrogen fertilizer should be avoided because it increases decay with little yield or bolting benefit.
