This research work was carried out in the towns of Taraco (Latitude 15° 17' 54" S, Longitude 69°48' 44" W, Altitude 3819 m) and Juliaca (Latitude 15° 26' 39" S, Longitude 70° 12' 28.2" W, Altitude 3826 m) in the department of Puno. The objectives of the research focused on the calibration and validation of the Aquacrop model for three varieties of quinoa (Blanca de Juli, Pasankalla, Salcedo INIA); the evaluation of the impact of ENSO on the simulated yields with Aquacrop in three planting seasons (S1: 25/10, S2: 10/11 and S3: 25/11) compared with different ENSO events (EN: El Niño, LN: La Niña and N: Neutral) and various EN categories (Weak El Niño: END, Moderate El Niño: ENM, Strong El Niño: ENF and Extraordinary El Niño: ENE) and LN (weak La Niña: LND, Moderate La Niña: LNM, Strong La Niña: LNF) ; and in the estimation of future yields by comparing the modeled historical yield of the period 1980-2010 (Yield 1980-2010) with the yields of the three General Circulation Models (CanESM2 (4.5 and 8.5); CNRM-CM5 (4.5 and 8.5) and MPI-ESM-MR (4.5 and 8.5) for three periods near (2010-2040), medium (2040-2070) and distant (2070-2090). The calibration and validation plots were conducted with good agronomic management and with fertilization levels in Taraco 60-54-46 and in Juliaca 80-50-40, under a randomized complete block experimental design. To calibrate and validate the Aquacrop model, the observed and simulated experimental data from the quinoa plots were compared, using the Pearson correlation coefficient (r), the root mean square error (RMSE), a Willmott agreement index (d), and the coefficient of determination (R2) which were statistically significant and allowed to compare the phenological and biometric parameters. After having calibrated and validated the model; The climatological characteristics of the study areas were previously evaluated, based on the events of the ENSO phases (El Niño, Neutral and La Niña) in three planting seasons, based on the results obtained in the validation of the models. They simulated the yields with the Aquacrop model for all the historical information, separating them for each of the extreme phases of the ENSO event and in its various categories and magnitude. And finally, Aquacrop was used to estimate future yields of the different varieties of quinoa with the three General Circulation Models and two emission scenarios.
