Other claims from this paper (8)
- Observation Recovery of N applied at planting was 30 to 55%.
- Observation Recovery of N applied at anthesis was 55 to 80%.
- Intervention effect The N rate or timing of application did not affect the contribution of soil N to total plant N.
- Association Fertilizer N applied at anthesis had the greatest influence on postanthesis N uptake, 17 to 77 kg N ha −1.
- Intervention effect Greater preplant N input did not increase postanthesis N uptake.
- Intervention effect Preplant N treatments did not affect extractable and mineralizable soil N at anthesis.
- Intervention effect Late N application is taken up efficiently by plants and does not decrease soil N uptake.
- Recommendation N should be supplied late in the season to achieve acceptable grain protein levels in irrigated bread wheat.
