Other claims from this paper (10)
- Intervention effect Soil copper sulphate gave the most satisfactory long-term copper deficiency control.
- Intervention effect A 22-kg/ha dressing in two consecutive years controlled deficiency as effectively as 44-kg and 66-kg/ha dressings.
- Intervention effect Copper polyphenol at 4.5 1/ha did not give satisfactory deficiency control.
- Intervention effect Foliar copper sulphate at 2.2 kg/ha gave satisfactory results.
- Intervention effect Foliar copper polyphenol at 9.0 1/ha gave satisfactory results.
- Intervention effect Copper polyphenol caused less foliar scorch than copper sulphate at growth stage 21-23.
- Intervention effect Copper polyphenol caused slight foliar scorch at growth stage 31.
- Intervention effect Soil copper EDTA reduced crop yields.
- Intervention effect Foliar copper EDTA reduced crop yields.
- Intervention effect Both chelated compounds induced manganese deficiency symptoms.
