Other claims from this paper (11)
- Intervention effect High nitrogen increased yield fourfold when sulphate was added.
- Intervention effect High nitrogen without sulphate caused sulphur deficiency.
- Intervention effect High nitrogen without sulphate reduced yield and tiller number.
- Intervention effect SO2 exposure did not affect yield when sulphate was supplied.
- Intervention effect At low nitrogen, added sulphate did not affect yield or tiller number.
- Intervention effect At low nitrogen, SO2 exposure did not affect yield or tiller number.
- Intervention effect SO2 exposure was associated with a small increase in dead leaf proportion at second harvest.
- Intervention effect SO2 raised leaf total sulphur from 0·045% to 0·102% in deficient plants.
- Intervention effect SO2 raised leaf sulphate sulphur from 42 to 153 parts 10−6 in deficient plants.
- Intervention effect SO2 exposure always increased organic sulphur content of leaves.
- Intervention effect SO2 exposure showed no evidence of an increased transpiration coefficient in plants with adequate soil sulphur.
