Resumo: | ABSTRACT: The production and quality of roses are influenced by fertilization management. The aim of this experiment was to evaluate the effects of doses of iron (Fe) in the production of potted rose bushes ( Rosa hybrida ). Treatments were based on five doses of Fe (0, 1, 3, 5 and 15mg kg-1) applied on the substrate, in a randomized block design with four replications. Seedlings presented two pairs of leaves and were individually transplanted into plastic pots (0.8dm3) containing commercial substrate. Each experimental plot consisted of a vase with a plant with two flower stalks. The following parameters were evaluated: number of leaves and flowers per flower stalk; dry matter production of roots, leaves and flowers; plant height and diameter and floral longevity. In addition, foliar levels of total chlorophyll and Fe were determined. Fertilization with Fe increases the production and quality of flowers of the rosebush cv. 'Shiny Terrazza' (r). Dose of Fe to be added to the substrate used in this study for maximum economic efficiency for this cultivar is 3.6mg kg-1.
