Resumo

The objective of this study was to evaluate the accumulation of NPK in cut chrysanthemum, cv. Jospithoven, at different phenologic phases, in the summer. The experiment was carried out in greenhouse environment, in Goiás State, Brazil. The population density was 80 seedlings m-2. The experimental design was completely randomized, with plots split in time, and four replications. The plant portion factor (stem, leaf, inflorescence and whole plant) was applied to plots, and the development phases (45, 60, 75, 90, 105, and 120 days) applied to sub-plots. The plant nutrition was 133 g m-2 of thermophosphate Yoorin and 150 g m-2 of fertilizer formula 5-25-15, which was added to the circulating nutritive solution of calcium nitrate (20 g m-2), during all the evaluated period, alternated with potassium sulfate (30 g m-2) and potassium nitrate (30 g m-2), each fifteen days. It was concluded that NPK demand by chrysanthemum var. Jospithoven, during the growing cycle, ranges according to the plant age and the organ studied, having been more accentuatedin the leaves and 105 days after sowing.
