Abstract

The potato is one of the most economically important crops in Brazil, and among the items that most cost the production is seed potatoes. The deficiency of one nutrient can interfere with the absorption and accumulation of the others in plants. The aim of this work was to quantify the optimal potassium (K) dose for minituber basic seed potato yield in hydroponic system. The experiment was installed in a greenhouse with the Agata cultivar minitubers. The treatments consisted of five doses of K (0.0; 2.5; 5.0; 7.5 e 10.0 mmol L-1) with four repetitions. The experimental design was a randomized block design. Data were submitted to analysis of variance and regression. The number of tubers, fresh mass, classification and dry mass were measured. The content of K and content other nutrients in the seed potato tubers were also evaluated. In the hydroponic systems, the maximum yield per plant was 48.41 tubers obtained with 6.15 mmol L-1 of K and maximum mass of fresh matter was 646.6 g.
