Abstract

The study was developed in the San Luis communities at 3128 masl and Tamboloma at 3635 masl, Tungurahua province, in two production batches of potato (Solanum tuberosum L.) with 3 varieties, I -Fripapa, I -Libertad and I- Puca Shungo; The objective was to evaluate the application of two doses of potassium, to establish the existence of an improvement in the desired characteristics for frying. With a completely randomized block statistical design, with 3 repetitions. The potassium doses used were 120kg / ha and 150kg / ha, the application was made at 21 and 65 days, after sowing. The variables applied in the research were plant emergence, days to flowering and harvest, yields per variety and total yield, obtaining that the variety Puca Shungo is the highest in yield in the two batches, and a survey of 7 people belonging to The CONPAPA association through sensory tests determined that the three varieties obtain acceptance and palatability. Regarding profitability, the T9v3k2 treatment in batch one and the T8v3k1 treatment in batch two, presenting a margin of 1.56% and 1.58%, these being the most profitable. We conclude that the application of potassium is favorable for the potato crop.
