e6“At harvest, SB23 enhanced biomass nitrogen accumulation and nitrogen use efficiency, with the 75%N + biostimulant treatment achieving the highest plant N uptake (25% above the reduced-N control) and the greatest partial factor productivity of nitrogen (51.8 kg grain kg−1 N applied), while both 100%N treatments showed the lowest efficiency”

- Intervention effect SB23 biostimulant significantly increased wheat leaf chlorophyll concentration at 30 and 60 DAA compared with untreated control.
- Intervention effect SB23 biostimulant promoted wheat biomass accumulation at 60, 90 and 120 DAA compared with untreated control.
- Intervention effect The 75% N plus biostimulant treatment improved wheat biomass by up to 23% relative to the reduced-N control.
- Intervention effect The 75% N plus biostimulant treatment improved wheat grain yield by 14% relative to the reduced-N control.
- Association Mid-season chlorophyll is strongly associated with wheat biomass.
- Association Mid-season chlorophyll is strongly associated with wheat carbon assimilation.
- Association Wheat biomass at 60 DAA is highly correlated with grain spike weight.
- Intervention effect SB23 enhanced wheat biomass nitrogen accumulation.
- Intervention effect SB23 enhanced wheat nitrogen use efficiency.
- Intervention effect The 75% N plus biostimulant treatment gave the greatest partial factor productivity of nitrogen, 51.8 kg grain kg−1 N applied.
- Intervention effect Both 100% N treatments showed the lowest nitrogen use efficiency in wheat.
- Observation SB23 under reduced N application gives an estimated cost–benefit advantage of approximately A$170 ha−1 in wheat.
