Other claims from this paper (19)
- Intervention effect Onion growth was slightly inferior at 0.2me sulphate without deficiency symptoms.
- Intervention effect Onion grew better at 0.5 to 10me sulphate.
- Observation Onion had no chlorine deficiency symptoms even at zero chloride.
- Observation Onion grew normally from zero to 10me chloride.
- Association Concentrations above 25me reduced growth in the sulphate and chloride series.
- Intervention effect Growth was similar with sulphate versus chloride cations for cabbage, turnip and onion.
- Intervention effect Growth under ammonium sulphate was similar to growth under ammonium chloride.
- Intervention effect Both ammonium treatments had markedly inferior growth to other nitrogen forms.
- Intervention effect Leaf sulphur concentration was higher under sulphate than chloride.
- Intervention effect Leaf chlorine concentration was higher under chloride than sulphate.
- Association Higher sulphate or chloride levels from 12 to 48me reduced onion and turnip growth.
- Intervention effect Growth did not differ between sulphate and chloride series.
- Intervention effect Cabbage growth increased with phosphorus through P 0.6me under nitrate treatments.
- Intervention effect Raising phosphorus to P 3me did not further increase cabbage growth.
- Intervention effect Phosphorus did not affect growth in ammonium sulphate treatments.
- Intervention effect Cabbage growth with ammonium sulphate was markedly inferior to other nitrogen forms.
- Association Leaf phosphorus concentration rose with phosphorus supply.
- Observation Leaf phosphorus concentration was highest under ammonium sulphate.
- Observation Phosphorus deficiency appeared at P 0 and 0.2me regardless of nitrogen form.
