- Observation Available soil zinc was very low, ranging from 0.38 to 2.24 mgkg-1 across extraction methods.
- Method / resource Cate-Nelson analysis determined zinc critical limits for soil and maize across extraction methods.
- Intervention effect Zinc levels significantly increased maize dry matter yield.
- Intervention effect Zinc levels significantly increased maize grain yield.
- Method / resource Approximately 11 kg Zn ha-1 was estimated as the optimum zinc sulfate level for maize zinc uptake.
- Intervention effect Zinc fertilizers significantly improved grain yield in the field experiment.
- Intervention effect Zinc sulfate at 9.0 kg ha-1 produced maximum maize grain yield of 7.9 tha-1 in 2009.
