Other claims from this paper (11)
- Association Water was the major limiting factor for grain yield and protein concentration.
- Intervention effect Grain yield after fallow was greater than after field pea, 1958 versus 1754 kg ha−1.
- Intervention effect Protein concentration was similar after fallow and field pea.
- Intervention effect Increasing nitrogen input reduced grain yield from 1933 to 1779 kg ha−1.
- Intervention effect Increasing nitrogen input improved protein concentration from 16.3 to 16.8%.
- Intervention effect The higher nitrogen rate resulted in negative nitrogen use efficiency.
- Intervention effect Nitrogen application method did not significantly affect yield and protein.
- Intervention effect Split nitrogen application at the lower rate showed a trend toward higher yield in a wetter year.
- Intervention effect The 2017 drought lowered harvest index.
- Intervention effect Harvest index was lower at 135 than 65 kg ha−1 nitrogen, especially in the dryer year.
- Mechanism Excess nitrogen in water-limited conditions may cause haying-off.
