Other claims from this paper (10)
- Observation Grain yield varied significantly among maize varieties at all nitrogen rates.
- Observation Harvest index, nitrogen efficiency and responsiveness also varied among genotypes.
- Observation Tested varieties were classified into four nitrogen efficiency and responsiveness types.
- Observation Hudan 4, Shanzi 1 and Yedan 19 were high-efficiency, high-response types.
- Observation Zhongdan 2 and Yuyu 22 were low-efficiency, low-response types.
- Observation Shandan16, Shandan 902 and Hudan 2000 were high-efficiency, low-response types.
- Observation Shandan 9 and Nongda108 were low-efficiency, high-response types.
- Association Nitrogen accumulation did not accurately reflect nitrogen use efficiency.
- Association The contribution of nitrogen utilization efficiency to nitrogen use efficiency depended on nitrogen rate.
- Method / resource Nitrogen index reflected nitrogen use efficiency at all nitrogen rates.
