The orchid Dendrobium nobile is nature of Himalaia and Sri Lanka, being adapted to the brazilian weather conditions. The objective of this experiment was to evaluate the vegetative growth of Dendobium nobile plants fertirrigated with Sarruge nutritive solution in diferents concentrations. Plants were cultivated in black plastic vases in a greenhouse with 50% of brightnen, watered 2 times a week and fertirrigated 1 time a week. The substrate was used de-fibered xaxim. The treatments were used: T1) Control; T2) Castor bean cake more bone powder organic fertilizer 2:1; T3) Sarruge 100%; T4) Sarruge 25%; T5) Sarruge 50%; T6) Sarruge 75%; T7) Sarruge 125%; T8) Sarruge 150%. A randomized complete block design was used with 10 replications. Growth and rooting were assessed after seven months. Dendrobium nobile performed best was observed in 75% concentration Sarruge solution.
