Other claims from this paper (9)
- Intervention effect Photosynthesis, stomatal conductance and chlorophyll increased with higher nitrogen and lower seed rate.
- Intervention effect NR and GS activities increased with higher nitrogen and lower seed rate.
- Intervention effect Plant tillers, grain yield and pre-anthesis dry matter were highest at N235 plus SR180.
- Intervention effect N translocation and N agronomic and recovery efficiencies were highest at N235 plus SR180.
- Intervention effect N uptake efficiency was highest at N235 plus SR180.
- Intervention effect Raising seed rate from 135 to 180 kg ha−1 increased grain yield by 12.9 %.
- Intervention effect Raising seed rate from 135 to 180 kg ha−1 increased nitrogen uptake efficiency by 9.1%.
- Recommendation Authors estimate that raising seed rate by about 0.6 kg ha−1 could replace 1 kg N ha−1.
- Recommendation Authors recommend N235 plus SR180 to maximize grain yield and improve nitrogen use efficiency.
