    Potatoes are a very important crop for humanity, since of its production volumen ranked fourth in global, The tuber is threatened by phytosanitary issues, and the lack of knowledge of farmers multiplication systems using cuttings are not practiced. This research evaluated rooting in cuttings of two potato varieties: Súperchola (Solanum tuberosum) Iniap -Puca Shungo (Solanum andígenum) at the Santa Catalina Experimental Station INIAP located in the Pichincha province, Mejía canton, Cutuglagua parish. Using a completely random block design (CRBD) with a factorial arrangement AxB, where factor A represents the potato varieties (Súperchola and Iniap-Puca Shungo) and factor B represents the rooting (Trichoderma harzianum, Bacillus subtilis, coffee in based ‘Minerva’, and as witness the Hormonagro1), so the research includes eight treatments with three replications, giving us in total 24 experimental units. The variables evaluated were percentage of rooting (%), height of shoots (cm), number of roots, root length (cm) and root weight (gr) in which was carried out a variance analysis and test Tukey of 5%. Based on the result nterpretation, it was identified that statistically all treatments had the same percentage of rooting, but in values the treatment V2E2 (INIAP-Puca Shungo + Bacillus subtilis) showed the best rooting (92.18%); the best treatments for shoot length were V2E2 (INIAP-Puca Shungo + Bacillus subtilis) with an average of (4.26 cm) and V1E2 (Súperchola + Bacillus subtilis) with an average of (3.93 cm). In the variables related to the root system, the treatment V2E2 (INIAP-Puca shungo + Bacillus subtilis) with the number of roots (9.89); in the length of roots with an average of (9.23 cm) and however in the weight of roots the treatment V2E3 (INIAP-Puca shungo + coffee base in "Minerva") with (0,36gr), rooting agents will help to promote plant development both at the root and vegetative level. In addition, the benefit/cost analysis of the project was carried out with a value of $1.39, since for each dollar invested there was a profit of 0.39 cents. Where it is stated that the application of rooting agents on cuttings from mother plants helps to obtain potato seedlings.
