Little research has been conducted on the nutritional requirements of ornamental tropical plant cuttings including heliconia, ginger torch, alpinia and ornamental ginger. In order to evaluate the growth, identify the visual symptoms of deficiencies in Heliconia psittacorum x H. spathocircinata, Aristaguieta, cv. Golden Torch, and determine the foliar content of macronutrient and zinc, this research was carried out under greenhouse conditions using the Missing Element Technique. The experimental design was completely randomized blocks with five replicates and eight treatments as follows: complete (supply of all macro- and micronutrients) and omission of -N, -P, -K, -Ca, -Mg, -S and -Zn. Symptoms of deficiencies appeared in the following order: N> S> Mg> K> P> Zn> Ca. Nitrogen and Mg were the most limiting nutrients of plant growth. The omissions of nutrient reduced de foliar content in relation to complete treatment. The leaf contents of macronutrients (g kg-1) and Zn (mg kg-1) in H. psittacorum. cv. Golden Torch, showing no deficiency symptoms (complete) were: 21.95 (N); 1.77 (P); 2.59 (K); 9.22 (Ca); 4.46 (Mg); 6.71 (S); and 46.58 (Zn), and in plants showing deficiency (omission of nutrients) 13.24 (N); 0.52 (P); 1.12 (K); 4.14 (Ca); 1.58 (Mg); 1.30 (S); and 12.74 (Zn).
