Other claims from this paper (10)
- Observation Maximum yield at Fanjiatun occurred at N 251 kg/ha.
- Observation Maximum yield at Yushu occurred at N 206 kg/ha.
- Observation Economic optimum yield at Fanjiatun corresponded to N 227 kg/ha.
- Observation Economic optimum yield at Yushu corresponded to N 134 kg/ha.
- Association Increasing nitrogen rates significantly improved the maximum nitrogen absorption rate and total uptake.
- Observation The date of maximum nitrogen absorption occurred earlier at Fanjiatun.
- Association Residual nitrate nitrogen in the 0-30 cm soil profile increased with nitrogen rates.
- Observation Nitrogen agronomic efficiency, recovery efficiency and partial factor productivity were higher at lower-fertility Fanjiatun.
- Recommendation The authors suggest increasing nitrogen rates for high yield at lower-fertility sites like Fanjiatun.
- Recommendation The authors advise controlling nitrogen rate at higher-fertility sites like Yushu to improve yield and use efficiency.
