- Intervention effect At low base-tiller nitrogen, SSNM reduced the optimum dressing rate relative to the standard method.
- Intervention effect At low base-tiller nitrogen, CSNOA increased economic benefit relative to the standard method.
- Intervention effect At low base-tiller nitrogen, SSNM increased economic benefit relative to the standard method.
- Intervention effect At low base-tiller nitrogen, LAI increased optimum dressing rate and decreased economic benefit.
- Intervention effect At low base-tiller nitrogen, NNI increased optimum dressing rate.
- Intervention effect At low base-tiller nitrogen, NFOA increased optimum dressing rate.
- Intervention effect At low base-tiller nitrogen, NNI decreased economic benefit.
- Intervention effect At low base-tiller nitrogen, NFOA decreased economic benefit.
