“…Thus, growth rate may be reduced and the deficiency symptoms related to the already caused metabolic disorders may appear only later. On the other hand, the mean contents of P in the leaves in the present study were higher than the mean of 1.17 g kg -1 observed by Santos et al (2012), but lower than the range of 1.87 to 1.93 g kg -1 reported by Cerqueira et al (2008) and 1.77 g kg -1 obtained by Viégas et al (2014) for the cultivation of heliconias.…”

“…The mean leaf K contents observed in the present study are between 18.23 and 27.1 g kg -1 , and are higher than the range of 17.4 to 18.7 g kg -1 observed by Santos et al (2012), the amplitude of 14.0 to 16.5 g kg -1 (Cerqueira et al, 2008) and the value of 2.59 g kg -1 (Viégas et al, 2014). The leaf K contents in this study are below the range of 35-45 g kg -1 reported by Atehortua (1997), although no visual symptom of deficiency was observed at the field.…”

A B S T R A C TThis 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 K 2 O 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 favored the increase in leaf K content and the decrease in the contents of P, Ca and Mg in leaves of heliconias. Under the conditions of this experiment, it is recommended to apply 161.46 g of K 2 O hole -1 for a maximum yield of 9.89 stems m -2 per month.Adubação nitrogenada e potássica na produtividade e teores de macronutrientes em helicônia cv. Golden Torch R E S U M O Realizou-se este estudo com o objetivo de avaliar o efeito da adubação nitrogenada e potássica na produtividade e teores de macronutrientes em plantas de helicônia (Heliconia psittacorum x Heliconia spathocircinata Aristeguieta) cv. Golden Torch. O experimento foi conduzido segundo um delineamento experimental em blocos casualizados em esquema fatorial 4 x 4 correspondentes às doses de nitrogênio (0, 120, 180 e 240 g cova -1 de N) e de potássio (0, 120, 180 e 240 g cova -1 de K 2 O) com quatro repetições e cinco rizomas por parcela, em condições de campo. Após um ano de cultivo determinaram-se a produtividade em termos de número de hastes florais por metro quadrado e os teores foliares de N, P, K, Ca, Mg e S. As doses de nitrogênio aplicadas não exerceram influência na produtividade nem nos teores foliares dos macronutrientes avaliados. A fertilização potássica favoreceu o aumento do teor de K foliar e o decréscimo dos teores de P, Ca e Mg foliares; recomendamse, nas condições em que o experimento foi desenvolvido, 161,46 g cova -1 de K 2 O para a produtividade máxima de 9,89 hastes m -2 ao mês.

“…Sousa et al (2011) attributed the little flowering to water salinity, although it did not interfere in tillering. Santos et al (2012) attributed the non-flowering to the low level of applied phosphorus (P). Gervásio & Melo Junior (2014) when evaluating different levels of water depletion in organic substrate in pot cultivation of heliconias, obtained a high tillering, reaching up to 25 tillers per vase.…”

Potted cultivation of tropical flowers presents good projections for the northeastern region of Brazil; however, it still faces some peculiarities regarding conduction and management. The objective of this study was to evaluate the effect of tillering on the production of Heliconia psittacorum L.f. cv. Red Opal, grown in flowerpot. The experiment was carried out in a protected environment at the Campus of Agricultural Sciences (CCA) of UNIVASF, Petrolina - PE, Brazil, between 2014 and 2016. A completely randomized design was used, with four tiller densities per pot (4, 8, 12 and 16 tillers) and eight replications, totaling 32 plots. The irrigation system was automated and monitored by weighing lysimetry. Were evaluated: efficiency of water use (EUA); harvested flower stems (HC); ratio of harvested stems and number of tillers (HC / NP); number of leaves (NF); duration of vegetative (DFV) and productive phases (DFP); total cycle (CT); floral stem length (CHF); floral stem diameter (DH), bracts length (CB) and equivalent diameter of the collar (DECH). The results were subjected to regression test. The EUA was higher in the density of 16 tillers pot-1; the HC variable presented an increasing linear trend; a decreasing linear trend was detected for HC/NP, NF, DFP, DH, CB and DECH. The number of tillers in the pot does not limit the emission of floral stems. However, the quality of these is inversely proportional to the tiller density.

“…Work on the cultivation of potted Heliconia is still scarce in the national and international literature. Santos et al (2012) evaluated the growth and nutritional status of Golden Adrian Heliconia irrigated with treated domestic wastewater using 20-liter pots and did not observe floral stem emission even after nine months of cultivation. Similar results were observed by Melo et al (2002) in an experiment with 19 genotypes (species and cultivars) of Heliconia grown in pot and under conditions of free tillering even after 250 days of cultivation.…”

Flowers and ornamental plants cultivation in Brazil has grown over the years as economic activity. Pernambuco state is one of the major producers and exporters of Heliconia sp, a highlighting tropical flower in Brazil. However, detailed information regarding to the irrigation needed especially in semiarid conditions has been little studied. The objective was to evaluate different levels of water depletion in the substrate as indicators of irrigation time and its effects on growth and productivity of Heliconia psittacorum L.f. cv. Red Opal in pots. The experiment was conducted in a greenhouse covered with 50% shade cloth located at the Agricultural Sciences Campus in the Federal University of Vale do São Francisco in Petrolina, PE, Brazil. This is a semiarid region in Brazil where irrigation is necessary for the production of most crops. The experimental design was completely randomized, with six levels of water depletion in the substrate and five repetitions. The determination of the depletion level was performed by means of weighing lysimeters. The following parameters were evaluated: plants water consumption, the amount of macro and micronutrients applied and the number of tillers emitted. It was concluded that the water depletion level at 5% on the weight capacity of container allowed the increase in the number of tillers. However, the management of the crop under tiller free growth conditions inhibited the emission of floral stems from this crop, when grown in pots. The efficient use of water in semi-arid climate is a requirement for the sustainability and reduction of production cost.
