    Potato cultivation is one of the most important for its high production and nutritional value. It is the third most important crop in the world, the same one that presents phytosanitary and productivity problems due to the affectation of the tubercle for its planting. Potato production decreased by 17% between 2000 and 2020. The objective of this research was to evaluate rooting in cuttings of two potato varieties (Solanum tuberosum), Clone 11-9-91 and INIAP-CIP-Libertad, below deck to fulfillment this objective, were used four rooting: (Ascophyllum nodosum algae, lentil extract, willow extract, and acid Acid 1-Naphthaleneacetic) of which eight treatments with three replicates were implemented, arranged in a completely random block design (DBCA) where the variables were evaluated: percentage of cuttings, sprout height, root length, root numbers and root weight. The data obtained were analyzed in variance analysis in INFOSTAT 2.0 software, and for significance we used the Tukey tests for 5% in the sources of variation that presented statistical significance. The results determined that (T1) Ascophyllum nodosum algae + Clone 11-9-91 exhibited the best cuttings at 97.66%, followed by acid 1-Naphthaleneacetic + INIAP-CIP-Libertad (T8) with 97.40%. In the variables, height of sprout at 30 and 45 days (T1) algae Ascophyllum nodosum + Clone 11-9-91 with 3.73 cm and 4.74 cm respectively. It was establised that (T3) willow extract + Clone 11-9-91 was the best for the variable root length with 11.41 cm, as well as for the number of roots with 4.92 and root weight with 0.30 g. As for the analysis of costs for treatments of which the lowest cost was presented was the Acid 1-Naphthalacetic with $ 0.18 ctv. For Everything it was established through the using evaluated rooting can be obtained potato seedlings from cuttings.
