- Intervention effect Foliar Zn alone increased grain Zn concentration by 95.7% across six site-years.
- Intervention effect Foliar Zn with N increased grain Zn concentration by 101%.
- Intervention effect Foliar Zn with P increased grain Zn concentration by 67.9%.
- Intervention effect Foliar Zn with K increased grain Zn concentration by 121%.
- Association Foliar Zn interacted positively with N for increasing grain Zn at Sanyuan.
- Association Foliar Zn interacted positively with K for increasing grain Zn at Yangling.
- Association Foliar Zn interacted negatively with P for increasing grain Zn under all tested conditions.
- Observation Interaction effects on grain Zn were much smaller than the average treatment increases.
- Intervention effect Zn plus P increased grain Zn by an average 18.7 relative to foliar Zn alone.
- Intervention effect Zn plus N increased grain Zn by an average 26.5 mg kg-1 relative to foliar Zn alone.
- Intervention effect Combining foliar Zn with N, P or K did not adversely affect grain yield and other nutritional quality.
- Intervention effect Combined foliar nutrient applications slightly increased grain yield in some cases.
- Intervention effect Combined foliar nutrient applications slightly increased grain macronutrient concentrations in some cases.
- Intervention effect Foliar Zn lowered grain phytic acid:Zn molar ratios by 52.0% versus control.
- Intervention effect Zn plus N lowered grain phytic acid:Zn molar ratios by 53.1% versus control.
- Intervention effect Zn plus P lowered grain phytic acid:Zn molar ratios by 43.4% versus control.
- Intervention effect Zn plus K lowered grain phytic acid:Zn molar ratios by 63.5% versus control.
- Observation These treatment effects were consistent across four years and three soil N rates.
- Recommendation The authors prefer including Zn in foliar N or K applications for dietary Zn intake.
