Other claims from this paper (11)
- Association Dry matter accumulation increased with nitrogen rate.
- Intervention effect Dry matter allocation among organs did not differ with nitrogen rate.
- Observation Maximum nitrogen uptake occurred between 50% bolting and 50% flowering.
- Observation Other elements reached maximum uptake between 50% flowering and pod formation.
- Intervention effect Maximum yield was 2798 kg ha −1 at 102.3 kg N ha −1.
- Observation The economic optimum nitrogen rate was 93 kg N ha −1.
- Association Seed nitrogen concentration increased with nitrogen rate.
- Association Straw nitrogen concentration increased with nitrogen rate.
- Mechanism The authors attribute the results to the relation between nutrient uptake and dry matter production.
- Mechanism The authors infer that carinata efficiently scavenges residual soil nitrogen.
- Recommendation The authors suggest timing nitrogen application to stages of maximum nutrient uptake.
