Resumo: | Sodium is considered a beneficial element for plants and, for some cultures, it can partially substitute potassium nutrition. However, little is known in respect of the influence of this cation on coffee plant. The present study aimed to verify the effect of the supply of sodium in substitution of potassium on the growth and nutrition of the coffee seedlings (Coffea arabica L.) cv. Acaiá Cerrado selection MG-1474. The experiment, conducted in vases with nutrient solution in a completely randomized design, was made up of seven treatments: two sodium doses (0.9 and 1.8 mM) and five substitution proportions of potassium by the sodium (0, 25, 50, 75 and 100 %). Biweekly, the plant height, stem diameter and the number of pairs of leaves was evaluated for six months. At the end of this period, the dry matter production and the contents and accumulations of sodium and nutrients in the root, stem and leaf were determined. The substitution of the potassium by the sodium in 25% of the recommended base did not interfere significantly in the development of the plants; however, that substitution starting from 50 % reduced their dry matter production. The sodium uptake by the coffee plant seedlings was, in average, 24 times lower in comparison with that of potassium. Regarding the other nutrients, the proportions of sodium interfered little in their leaf contents, except magnesium, which presented considerably high uptake efficiency in the absence of potassium. Based on the results, under the studied conditions, it was concluded that the supply of sodium does not promote a benefit to the coffee plant seedlings, enabling reduced their growth starting from 50 % of substitution of the potassium by the sodium. |

O sódio é considerado um elemento benéfico para as plantas e, para algumas culturas, pode substituir parcialmente o potássio. Contudo, a influência desse cátion para o cafeeiro é pouco conhecida. Objetivou-se, no presente estudo, verificar o efeito do fornecimento de sódio em substituição ao potássio, no crescimento e nutrição de mudas do cafeeiro (Coffea arabica L.) cv. Acaiá Cerrado, seleção MG-1474. O ensaio, conduzido em vasos com solução nutritiva em delineamento inteiramente casualizado, foi constituído por sete tratamentos, sendo duas doses de sódio (0,9 e 1,8 mM) e cinco proporções de substituição do potássio pelo sódio (0, 25, 50, 75 e 100 %). Avaliou-se, quinzenalmente, a altura da planta, diâmetro do caule e o número de pares de folhas durante seis meses. Após esse período, determinou-se a produção de matéria seca e os teores e acúmulos de sódio e nutrientes na raiz, caule e folha. A substituição do potássio pelo sódio em 25 % da dose recomendada não interferiu significativamente no desenvolvimento das plantas; a partir de 50 % isso reduziu a produção de massa seca de caule e folhas. A absorção de sódio pelas mudas de cafeeiro foi, em média, 24 vezes menor em comparação à absorção de potássio. Com relação aos demais nutrientes, as proporções de sódio pouco interferiram em seus teores foliares, à exceção do magnésio, cuja absorção foi consideravelmente elevada na ausência de potássio. Diante dos resultados, sob as condições estudadas, conclui-se que o fornecimento de sódio não promove benefício às mudas de cafeeiro, podendo reduzir seu crescimento a partir de 50 % da substituição do potássio pelo sódio.
