- Intervention effect Zn20 increased seed production.
- Intervention effect Zn20 increased shoot dry matter yield.
- Intervention effect Other zinc treatments did not significantly raise, or decreased, shoot dry matter yield.
- Intervention effect Thousand seed weight was the yield component most affected by zinc.
- Intervention effect Plant height and head diameter did not change under zinc fertilization.
- Intervention effect Seed oil content peaked under Zn10.
- Intervention effect Zn30 and Zn60 reduced seed oil content relative to control.

- Intervention effect Foliar zinc sulfate produced the highest leaf zinc concentration in the second year, 175 mg kg−1.
- Intervention effect Zn20 increased leaf iron relative to control.
- Intervention effect Higher soil zinc sulfate rates decreased leaf iron.
- Intervention effect Soil zinc sulfate decreased leaf sodium and chloride concentrations.
- Intervention effect Zn20 yielded the lowest leaf sodium and chloride concentrations.
