In addition to being rich in nutrients, native potatoes have natural antioxidants (carotenoids, flavonoids and anthocyanins), which play a fundamental role in health and industry. In Ecuador, potatoes are the main crop grown in the northern highlands. In Ecuador, there are about 400 varieties grown in plots of 0.1 to 0.5 ha above 3200 m.a.s.l. At this altitude, the strong solar radiation and organic Andean soils give these products their special naturalness. A study was conducted in Loja to assess the effects of fertilization on anthocyanin content and morphological growth parameters during vegetative development of two native potato genotypes (Solanum tuberosum L.). A completely randomized field trial was conducted in which nine treatments and three replications were used; the factors considered were fertilization (3 levels) and potato genotype (2 levels). The anthocyanin variable was evaluated when the plant reached flowering. Morphological variables such as height, plant diameter was measured every 7 days, leaf area at the moment the plant reached flowering. PH and electrical conductivity were evaluated every 10 days. Based on a statistical analysis, genotype 2 (black potato) and fertilization influenced height and diameter directly, with treatment 4 (black+sulfur) having the best results. The other variables of pH and electrical conductivity responded positively to fertilization levels in all treatments, making alkaline soils. With magnesium and sulfur-based fertilization, which affect anthocyanin content, the black potato crop performs better than other potato varieties.
