    The present research titled "Evaluation of a Foliar Fertilizer at Three Doses on the Yield of Potato Crop (Solanum tuberosum) Variety 'Súper Chola' in Umbría, Aloasí, Mejía Canton" aims to evaluate and optimize the use of foliar fertilizers. The potato crop faces low yield issues in areas such as Aloasí, making it necessary to improve fertilization techniques. A quantitative and experimental research was carried out to analyze the efficacy of ANONE CPA fertilizer in four doses: 0 mg/L l,5 mg/L 2 mg/L 2,5 mg/L, exposed in 16 treatments with 3 replications each. For data analysis, the Chi-square and Fishers LSD test in SPSS were used. The results showed that after the second fertilizer application, a greater quantity of tubers and a better weight were obtained, with the 2.5 mg/L dose being the most efficient, since a yield of 21.94 Tn/ha was obtained, which exceeds national production. Concerning the economic analysis, it was identified that treatment 16 (2.5 mg/L) maximizes the benefits of potato production with a profit of more than $20000 per hectare. In conclusion, the 2.5 mg/L dose of ANONE CPA improved the soil, quality, and economic profitability of the potato (Solanum tuberosum) variety Super Chola.
