ABSTRACT
The goal of this research was to assess alternatives of biofertilization with Fosfotic, Safer-mycorrhiza, and their combination in the potato variety Superchola under semi-controlled conditions. The experiment was carried out in a greenhouse and the substrate used was a typical Andisol of the region. A Completely Randomized Design was used with three replications. These alternatives and their combinations with the NPK dose that is used in the region and with different reductions of it, were evaluated, forming a total of 23 treatments. The best integral results were obtained with the treatments in which mineral fertilization is combined with some of the biofertilization alternatives (Fosfotic and Safer-mycorrhizas), with which it is suggested that these studies be continued under field conditions in the Andisols of Carchi -Ecuador. It is demonstrated that both the inoculations with Fosfotic and Safer-mycorrhizas, as well as their joint inoculation, can constitute viable alternatives in the cultivation of potatoes in these soils. However, the reduction of the mineral fertilizers without combine that with biofetilizers implies a reduction of the production, so it is not recommendable.
