Other claims from this paper (8)
- Intervention effect Higher plant density promoted maize N absorption and leaf area index.
- Intervention effect Higher plant density raised total N uptake and radiation interception.
- Intervention effect Higher density raised dry matter accumulation, grain yield, NUE and radiation use efficiency.
- Intervention effect Increasing N rate significantly increased dry matter accumulation, grain yield and LAI.
- Intervention effect Increasing N rate significantly increased IPAR and RUE.
- Observation N use efficiency at NCK was low at 320 kg ha−1.
- Intervention effect Reducing N rate increased NUE despite a slight loss in grain production.
- Recommendation The authors recommend a 30% N reduction and 3 plants m−2 density increase versus LD to balance yield and resource efficiency.
