Other claims from this paper (6)
- Association In both years NUpE was positively related to grain yield and NUE in wheat.
- Association The high NUpE group had more total N accumulation than the low and medium NUpE groups, from re-greening to anthesis.
- Association The high NUpE group had higher N accumulation in grains than the low and medium NUpE groups, mainly due to increased N remobilization from the vegetative organs.
- Intervention effect Increasing planting density from 150 to 225 plants m−2 promoted N accumulation before stem elongation in wheat.
- Intervention effect Late application of more N fertilizer (splits 3:1:3:3 versus 5:1:2:2) boosted N accumulation from stem elongation to anthesis in wheat.
- Recommendation The authors recommend a combination of agronomic measures to achieve high yield and NUE in wheat through promoting pre-anthesis N accumulation and NUpE.
