NUTRITIONAL REQUIREMENTS OF THE BIRD OF PARADISE FLOWER (Strelitzia reginae Aiton)

Abstract

With the aim of understanding the nutritional balance and requirement of the bird of paradise flower (Strelitzia reginae Aiton), the need for nutrients under a commercial production system was quantified, in a plot established 10 years ago, with use of fertilization, pruning, irrigation, pest and disease control, with a population density of 1,250 plants ha^-1, through the chemical analysis of nutritional concentration in the biomass produced in a year. It was concluded that the annual nutrient requirement in the crop was the following: macronutrients (Kg ha^-1) N (68.22), P₂O₅ (23.23), K2O (145.73), CaO (134.66), MgO (10.38) and micronutrients (g ha^-1), Cu (174.7), Fe (282.4), Mn (288.2) and Zn (390.6).
