e1“Compared with conventional N fertilization (360 kg N ha −1 ), moderate fertilization at 240 kg N ha −1 resulted in steady and higher seed cotton yields of 5945 and 5603 kg ha −1 in 2017 and 2018, respectively, and improved NUE by 49.1–53.6%”

- Intervention effect Moderate N at 240 kg N ha-1 gave a higher seed cotton yield of 5945 kg ha-1 in 2017 than conventional 360 kg N ha-1.
- Intervention effect Moderate N at 240 kg N ha-1 improved NUE by 49.1–53.6% relative to conventional 360 kg N ha-1.
- Intervention effect Shifting N application later (N 064) increased lint yield and PFFPN by 4.4–7.7% relative to the conventional N 262 control.
- Intervention effect Shifting N application later (N 064) increased total N accumulation in reproductive organs by 6.1–14.4% relative to N 262.
- Intervention effect Shifting N application later (N 064) increased the average (Vt) accumulation rate by 25.2–49.0% relative to N 262.
- Intervention effect Shifting N application later (N 064) increased the maximum (Vm) accumulation rate by 15.0–48.7% relative to N 262.
- Intervention effect Shifting N application later (N 064) shortened the fast N accumulation period (∆t) by 15.2–24.4% relative to N 262.
- Intervention effect N 064 partitioned 15.6% more 15N to reproductive organs.
- Association NUE was significantly positively correlated with K, t1 and Vt.
- Association NUE was significantly positively correlated with Vm, Tm and 15N accumulation in middle and upper canopy bolls.
- Association NUE was negatively correlated with ∆t of total N accumulation in reproductive organs.
- Recommendation The authors recommend this N management strategy to improve NUE for cotton in arid areas.
