Other claims from this paper (7)
- Observation Two seasonal dry matter and nitrogen accumulation strategies occurred in oilseed rape.
- Association In 2008 and partly 2010, slow but sustained nitrogen and biomass accumulation accompanied high main-branch seed density.
- Association Main-branch seed density significantly depended on leaf nitrogen content at flowering onset.
- Association In 2009, rapid vegetative nitrogen accumulation produced large leaf biomass at flowering onset.
- Association The 2009 growth pattern was less effective for seed yield than the first strategy.
- Association Excess leaf nitrogen at flowering onset was associated with reduced secondary-branch pod seed density.
- Association Seed nitrogen content was the best predictor of final yield across nitrogen strategies.
