Other claims from this paper (11)
- Intervention effect Nitrogen application substantially increased haulm dry matter accumulation.
- Intervention effect Nitrogen application increased haulm nitrogen contents to an even greater extent than dry matter.
- Observation Dry matter and nitrogen content of haulms started to decline in the later part of the season.
- Observation Most nitrogen was relocated from haulms to tubers late in the season.
- Intervention effect An application of only 60 kg N ha-1 was sufficient to promote rapid canopy development, with only small reductions in dry matter and nitrogen accumulation until late in the season.
- Association Tuber yield, plant dry matter and nitrogen accumulation at maturity were related to crop nitrogen supply.
- Intervention effect The higher nitrogen rate reduced tuber dry matter content by 2.6% in 2000 relative to 60 kg N ha-1.
- Intervention effect The higher nitrogen rate reduced tuber dry matter content by 1.1% in 2001 relative to 60 kg N ha-1.
- Observation Apparent fertilizer nitrogen recovery on a whole plant basis ranged from 53 to 75%.
- Association The proportion of fertilizer recovered in tubers declined as nitrogen supply increased.
- Intervention effect The highest dry matter values were generally registered at 120 kg N ha-1.
