| Abstract: |
In Ecuador, potato cultivation is one of the most important items in the production systems of the Ecuadorian highlands, it is an important source of food, as well as being the main source of economic income for the peasant family. For this reason, in the present work, the yield of five early native potato varieties (Solanum tuberosum L.) was evaluated under the influence of different levels of chemical fertilization, where four early native potato varieties were evaluated plus a control local, under the influence of the influence of three levels of chemical fertilization (F1 100%; F2 75%; F3 50%). A fully randomized block divided parcel (DBA) design was used in a factorial arrangement (3×5), with 15 treatments, resulting from the combination of three fertilization types (F1, F2, F3) and four early native potato varieties . plus a chaucha type control (V1, V2, V3, V4, V5), with three repetitions, for a total of 45 experimental units (UE). Among the fertilizers used are 18-46-00 (DAP), 00-00-60 (KCl) and urea, of which the former was used in its entirety and 50% of 00-00-60 (KCl) at the time of planting, and the urea was applied in its entirety as well as the remainder of 00-00-60 (KCl) in the hilling. From the results obtained for the yield and from the statistical analysis carried out, no statistically significant differences were found for factor A (Fertilization), while for factor B (Variety) significant differences were found, and for the interaction (AB) statistical differences were found for the variable yield per hectare (t/ha). Tukey’s 5% test for factor B (Variety) placed the variety Carrizo (V4) as the one with the highest yield with 34.28 t/ha. Regarding the cost/benefit ratio of the evaluated treatments, it was demonstrated that the T5 treatment (F1V5) corresponding to the Witness variety with 100% fertilization had a higher cost/benefit ratio with values of USD 1.71/ha, and concluding that for every dollar invested, 0.71 cents are recovered.

From the results obtained for the yield and from the statistical analysis carried out, no statistically significant differences were found for factor A (Fertilization), while for factor B (Variety) significant differences were found, and for the interaction (AB) if statistical differences were found for the variable yield per hectare (t/ha).
