e0“N splitting of T 1N½, T 2N½ and T 3N0 increased wheat grain yield (61% in 2005/06 and 75% in 2006/07), biological yield (76% in 2005/06, 94% in 2006/07), and LAI (62% in 2005/06 and 2006/07)”

- Intervention effect The combined iodosulfuron and mesosulfuron treatment reduced weed biomass by 55% in 2006/07 versus the weedy check.
- Intervention effect Solfosulfuron reduced weed biomass by 37% in 2005/06 versus the weedy check.
- Intervention effect Solfosulfuron reduced weed biomass by 45% in 2006/07 versus the weedy check.
- Intervention effect Full nitrogen at tillering had the highest weed biomass, 353.6 kg h -1 in 2005/06 and 224.1 kg h -1 in 2006/07.
- Intervention effect Zero nitrogen at sowing and stem elongation had the lowest weed biomass, 65.6 kg h -1 in 2005/06 and 24.0 kg h -1 in 2006/07.
- Intervention effect Splitting nitrogen increased wheat nitrogen use efficiency.
- Intervention effect Nitrogen splitting increased wheat LAI and grain yield, with smaller increases in the presence of weeds.
- Intervention effect Integrating nitrogen and herbicide increased wheat LAI and grain yield more than either treatment alone.
- Intervention effect Integrating nitrogen and herbicide reduced weed biomass more than either treatment alone.
