The sweet potato (Ipomoea batatas L.) is a vegetable of great economic importance since it can be used for in natura consumption, for processing in agribusiness and/or biofuel production. The objective of this work was to evaluate the yield of three sweet potato cultivars: BRS Amelia, BRS Cuia and BRS Rubissol in the Northwest Region of Rio Grande do Sul. The experiment was conducted in the field for two consecutive years (harvests 2014/2015 and 2015/2016). The experimental design was in randomized blocks, evaluating 3 sweet potato cultivars for 2 agricultural years, with 4 replications. As results, it was observed that potato weights in the first year of study ranged from 272.0 g to 320.2 g. In the second year of evaluation, it ranged from 133.9 g to 247.1 g. In relation to the average productivity, the values obtained in the first year were 15.2 t ha-1 for BRS Amelia, 19.8 t ha-1 for BRS Cuia and 16.2 t ha-1 for BRS Rubissol. In the second year of evaluation, the values were 12.3 t ha-1 for BRS Amelia, 16.1 t ha-1 for BRS Cuia and 13.1 t ha-1 for BRS Rubissol. Cultivars presented yields higher than the national average from Brazil in the two evaluated years.
