| As helicônias se destacam pela beleza e variedade de formas e cores e estão entre as flores tropicais mais comercializadas no mundo. Foi avaliado o crescimento e o desenvolvimento de Heliconia psittacorum x H. spathocircinata, cv. Golden Torch, quanto à adubação orgânica e mineral. O experimento foi conduzido em campo, em delineamento inteiramente casualizado. Os tratamentos foram constituídos por quatro dosagens de adubo (testemunha (T1) solo local; esterco de boi (T2); adubo mineral NPK (T3) e esterco de boi + NPK (T4)), em dez repetições. Foram avaliados a altura da planta, número de brotações, época do florescimento, número, tamanho e peso das inflorescências. A combinação da adubação mineral (NPK) e orgânica (esterco) (organomineral) afetou... |

| ABSTRACT This study evaluated the selectivity of herbicides applied post-emergence on ornamental plants of Alpinia purpurata, Strelitzia reginae and Heliconia psittacorum. The study was conducted in two seasons. The experimental design was completely randomized with four replications. The treatments were: fluazifop-p-butyl (87.5 g ha-1), quizalofop-p-ethyl (75.0 g ha-1), sethoxydim (184.0 g ha-1), quinclorac (375.0 g ha-1), chlorimuron-ethyl (15.0 g ha-1), clethodim + fenoxaprop-p-ethyl (37.5 + 37.5 g ha-1), bentazon (720.0 g ha-1), fomesafen (225.0 g ha-1), and a control without any herbicide. In general, all tested herbicides and doses were selective for the three studied species. Although plants of A. purpurata and H. psittacorum have shown symptoms of... |

| ABSTRACT This study aimed to evaluate the effect of nitrogen (N) and potassium (K) fertilization in yield and contents of macronutrients in heliconia plants (Heliconia psittacorum x Heliconia spathocircinata Aristeguieta) cv. Golden Torch. The experiment was set in a randomized block design, in a 4 x 4 factorial, corresponding to N doses (0, 120, 180 and 240 g of N hole-1) and K doses (0, 120, 180 and 240 g of K2O hole-1) with four replicates and five rhizomes per plot, under field conditions. After one year of cultivation, yield (number of flower stems per square meter) and the leaf contents of N, P, K, Ca, Mg and S were determined. The applied N doses did not influence either yield or the leaf contents of the evaluated macronutrients. K fertilization... |
