Other claims from this paper (13)
- Intervention effect Increasing nitrogen application significantly enhanced maize yield.
- Observation Jingpin 450 (JP450) reached its highest yield of 8.9 t/ha under N250.
- Observation Xianyu 335 (XY335) reached its highest yield of 9.2 t/ha under N300.
- Observation Qiule 368 (QL368) reached its highest yield of 10.1 t/ha under N250.
- Observation Across all nitrogen treatments, the yield ranking was QL368 > XY335 > JP450.
- Association High-nitrogen-efficiency maize varieties had higher post-anthesis nitrogen accumulation throughout the growth period.
- Association High-nitrogen-efficiency maize varieties promoted translocation of post-anthesis nitrogen to the grains.
- Association High-nitrogen-efficiency maize varieties increased grain nitrogen content at maturity.
- Association High-nitrogen-efficiency maize varieties ultimately improved yield.
- Observation Qiule 368 (QL 368) achieved high yields under both low- and high-nitrogen conditions.
- Mechanism Author interpretation: the high yield of QL 368 is primarily due to its high pre-anthesis nitrogen translocation rate and substantial post-anthesis nitrogen accumulation.
- Association Enhanced nitrogen translocation to the grains improved nitrogen use efficiency in high-efficiency maize.
- Association Enhanced nitrogen translocation to the grains strengthened the dry matter production capacity of the plant.
