Efeitos de diferentes doses de cloreto e de sulfato duplo de potássio e magnésio foram estudados no crescimento de mudas de guaranazeiro cultivado em Latossolo Roxo em condições de casa de vegetação. Utilizaram-se as doses de zero, dois, quatro, oito, dezesseis e trinta e dois gramas de K2O por planta. Os efeitos foram avaliados através de sintomas nas folhas, altura da planta, diâmetro do caule, número de folhas simples e compostas, número de plantas sobreviventes, peso seco da folha, caule e raiz. O cloreto de potássio mostrou, a partir da dose de 6,66g por planta, ser mais tóxico do que o sulfato duplo de potássio e magnésio. Effects of several rates of potassium chloride and potassium and magnesium double sulphate in potted "Guaraná" (Paullinia cupana H.B.K.) seedlings, growing in a Latosolic B "Terra Roxa" soil in greenhouse conditions were studied. The experimental design was in randomized blocks with eleven treatments and seven replications. Data were obtained for the following variables: toxicity symptoms; number of surviving plants; plant height; stem diameter; number of single, composite and total leaves; plant top and root dry weight; visual evaluation for the top plant parts and root system. Based on these data it was stablished the plant response and the degree of toxicity for the several rates of fertilizer applied
