In response to Zn deficiencies in vulnerable populations, crop biofortification is proposed as a solution strategy. The objective of this research was to evaluate the effect of foliar zinc fertilisation (FF-Zn) on biofortified potato clones. Four biofortified clones with different levels of Zn levels (High, Medium, Low in Zn, and high in Fe and Zn) and a commercial variety (Yungay) were grown in a greenhouse. This study involved two foliar application treatments (0% and 0.10% w/v), arranged in a factorial design (5Ax2B) with split plots, 4 replicates/treatment, and 5 plants per plot. At harvest, the yield components were evaluated, and the raw tuber samples were collected to determine micronutrients in the laboratory. For all yield components, linear mixed model analysis did not show significant interaction effects (GxD), but highly significant differences were observed between G. Zinc concentration in tubers showed a highly significant effect in the interaction (GxD). Simple effects analysis showed that biofortified genotypes responded to FF-Zn by significantly increasing their Zn concentrations on average by 43% (range 28 to 61%). In contrast, the Yungay variety observed a 6% increase. This study demonstrated that biofortified clones respond better to FF-Zn compared to the commercial variety without biofortification. Therefore, agronomic and genetic biofortification are synergistic strategies that can achieve a significant increase in tuber-level Zn concentrations.
