Other claims from this paper (8)
- Intervention effect Soil-applied zinc increased tissue Zn concentration by 11.9 mg Zn kg-1 above the control.
- Intervention effect Zinc seed treatments increased tissue Zn concentration by 4.7 mg Zn kg-1 above the control.
- Observation In 1999, zinc deficiency occurred at both locations.
- Intervention effect Zn-treated seed performed equal to or better than soil-applied Zn in dry matter, tissue Zn concentration and grain yield.
- Recommendation Seed Zn concentrations of 2.2 to 5.7 g Zn per kg seed are an economical alternative to soil-applied Zn.
- Observation Tissue Zn concentration did not differ among the cultivars tested.
- Observation Seed treatment with ZnSO4 gave net seed concentrations of 1.0, 2.2 and 4.7 g Zn per kg seed.
- Observation Seed treatment with ZnEDTA gave net seed concentrations of 1.4, 2.8 and 5.7 g Zn per kg seed.
