Resumo: | The objective of this study was to evaluate potassium and chloride accumulation in, and the yield and quality of the potato tubers of the Asterix cultivar, under the application of two potassium fertilizer sources (KCl and K2SO4.2MgSO4) and their combinations. The experimental design was a randomized complete block with five treatments and four replications in a factorial scheme with a subdivided plot. The presence of greater than 61.8% of the recommended dose of chloride in potassium fertilization affects potato plant growth, with less dry matter accumulation in the aerial part. This does not occur in the tubers because of lower nutrient translocation to the tubers. K accumulation varies between levels depending on the companion ions of the sources. Throughout the cycle, the amount of chloride increased in the aerial parts and tubers with an increase in the percentage of KCl. The total productivity is affected by the use of a combination of potassium sources in different proportions, with a maximum yield of 41.3 t ha-1 with a combination of 64.5% KCl and 36.5% K2SO4.2MgSO4. Soluble solids did not vary with the sources at a dose of 180 kg ha-1 K2O. |

O delineamento experimental foi em blocos casualizados, com cinco tratamentos e quatro repetições, em esquema fatorial com parcela subdividida. A presença de cloreto na fertilização potássica acima de 61,8% da dose recomendada afeta o crescimento das plantas de batata, com menor acúmulo de matéria seca na parte aérea. Isso não ocorre nos tubérculos devido à menor translocação de nutrientes para os tubérculos. O acúmulo de K é variável entre os níveis, dependendo dos íons companheiros das fontes. Ao longo do ciclo, a quantidade de cloreto aumenta na parte aérea e tubérculos com o aumento da % de KCl. A produtividade total é afetada pelo uso da combinação das doses da fonte de potássio, com produtividade máxima de 41,3 t ha-1 com a associação entre 64,5% KCl e 36,5% KCl and K2SO4.2MgSO4. Os sólidos solúveis não variaram com as fontes na dose de 180 kg ha-1 K2O.
