This field research shows that application of Zn fertilizers or Zn-enriched NPK fertilizers offers a prompt solution to increasing the Zn concentration in Andean potato tubers, and represents a useful complementary approach to on-going breeding programs. The diploid Chaucha cultivars that showed high tuber Zn concentrations in the absence of Zn fertilization also showed correspondingly higher Zn concentration in tubers following foliar and soil applied Zn. High levels of Zn in potato tubers may significantly improve the diets of Zn-deficient populations with high intake of potato and contribute to better nutrition
