Other claims from this paper (10)
- Intervention effect Increasing nitrogen increased wheat yield attributes, biomass and grain yield over the control.
- Association Nitrogen uptake predicted LAI with 84% predictability.
- Association Water use accounted for 75% of variation in LAI estimates.
- Association Lower water consumption was associated with less leaf area and lower biomass and grain yields.
- Observation Biomass gain per water use peaked at 53.1 kg/ha-mm during 60–90 days.
- Observation Biomass gain per water use was 28.3 kg/ha-mm during 90-120 days.
- Observation Biomass gain per water use was 6.7 kg/ha-mm during 0-60 days.
- Association Biomass response to nitrogen uptake was higher during 60-90 DAS than 0-60 DAS.
- Association Maximum wheat growth rates coincided with highest water and nitrogen use during 60-90 DAS.
- Recommendation The authors recommend relatively less water during 0-60 DAS than later periods.
