Other claims from this paper (10)
- Intervention effect Nitrogen fertilizer increased tobacco production.
- Observation Nitrogen was distributed mainly in tobacco stems and leaves.
- Association Nitrogen in stems and leaves increased with fertilizer rate.
- Association The fertilizer nitrogen proportion in roots, stems, buds and terminal buds first increased then decreased with fertilizer rate.
- Association The fertilizer nitrogen proportion in leaves generally rose with fertilizer rate.
- Observation Nitrogen loss and wastage mainly originated from soil nitrogen as fertilizer rate increased.
- Association Increasing nitrogen fertilizer rate aggravated nitrogen loss.
- Association Increasing nitrogen fertilizer rate raised the soil nitrogen surplus.
- Association Increasing nitrogen fertilizer rate reduced nitrogen recycling.
- Recommendation The authors identified T8 at 120 kg/hm2 as the best nitrogen fertilizer rate when yield, quality and nitrogen utilization were considered.
