Other claims from this paper (12)
- Intervention effect Deficit irrigation reduced canopy production capacity relative to normal irrigation.
- Intervention effect Nitrogen application under deficit irrigation increased gas exchange, SPAD and LAI.
- Intervention effect Nitrogen application increased net photosynthetic rate by 40.7% relative to N0.
- Intervention effect Nitrogen application increased water use efficiency by 12.5%.
- Intervention effect Nitrogen application increased upper-surface thickness, stomatal aperture and petiole cross-sectional area.
- Intervention effect The treatment increased taproot yield by 19.7%.
- Intervention effect The treatment increased sugar yield by 57.6%.
- Intervention effect N2 produced higher taproot yield than N1.
- Intervention effect N2 did not significantly increase sugar yield relative to N1.
- Intervention effect N2 did not significantly increase WUE relative to N1.
- Intervention effect N2 decreased harvest index by 9.3% relative to N1.
- Recommendation The authors recommend deficit irrigation with 150 kg N ha −1 during early growth to increase WUE without yield loss.
