Other claims from this paper (6)
- Intervention effect Mean cumulative N2O–N emissions increased with N rate (0, 90 and 180 kg N ha−1)
- Intervention effect Yield-scaled N2O–N emissions were 22% greater with side-dress timing than with pre-emergence timing
- Intervention effect Mean cumulative N2O–N emissions were higher with side-dress timing than with pre-emergence timing
- Intervention effect Mean cumulative N2O–N emissions were lower with nitrapyrin than without it
- Intervention effect Overall yield-scaled N2O–N emissions were 22% lower with nitrapyrin than without the inhibitor
- Association The effect of nitrapyrin on yield-scaled N2O–N emissions did not interact with N rate or timing
