Other claims from this paper (4)
- Intervention effect Sulphate of ammonia decreased wheat yield by about 10 per cent in three experiments on light gravelly soil, irrespective of application time.
- Mechanism The yield decrease from sulphate of ammonia is ascribed to more lodging and a greater incidence of foot rot.
- Intervention effect Early dressings of sulphate of ammonia did not affect wheat germination or plant establishment.
- Intervention effect Early dressings of sulphate of ammonia tended to increase wheat tiller formation by the end of February.
