Other claims from this paper (14)
- Intervention effect Dry matter accumulation in tobacco parts increased with irrigation amount.
- Intervention effect Tobacco dry matter accumulation first increased then decreased as nitrogen application increased.
- Intervention effect Excess nitrogen decreased tobacco dry matter accumulation.
- Intervention effect High water and middle nitrogen treatment T8 had the highest tobacco dry matter accumulation.
- Association Total dry matter did not change obviously with increasing root-shoot ratio.
- Association The proportion of leaf dry matter decreased as root-shoot ratio increased.
- Association Root dry matter allocation increased with root-shoot ratio and showed a very significant positive linear correlation.
- Intervention effect T8 with high water and middle nitrogen had the highest tobacco yield.
- Intervention effect T1 with low water and low nitrogen had the lowest tobacco yield.
- Intervention effect T2 with low water and middle nitrogen had the highest tobacco water use efficiency.
- Intervention effect T9 with high water and high nitrogen had the lowest tobacco water use efficiency.
- Intervention effect Increasing nitrogen application increased tobacco water use efficiency.
- Recommendation The authors recommend 500 mm irrigation and 90 kg/hm2 nitrogen as the best coupling treatment for tobacco.
- Recommendation The authors recommend balancing tobacco yield, water use efficiency and consumption by reducing irrigation while maintaining high yield.
