e0“With respect to the higher N application at sites of high plant available soil water capacity, although the already high yield levels were not increased further, the protein quality was significantly improved in the first season within all treatments and in the second season in the irrigated treatments.”

Other claims from this paper (9)
- Association Site was the primary factor explaining variability in grain yield.
- Association Rainfall distribution affected annual overall yield.
- Intervention effect Increasing nitrogen at low water capacity sites did not raise grain yield.
- Intervention effect Increasing nitrogen at low water capacity sites did not improve quality.
- Recommendation The authors recommend reduced nitrogen on low water capacity sites.
- Intervention effect Higher nitrogen did not further increase already high yield at high water capacity sites.
- Intervention effect Higher nitrogen significantly improved protein quality in the first season across treatments.
- Observation Residual nitrate after harvest was low.
- Recommendation The authors consider a higher nitrogen rate advantageous at high water capacity sites.
