The present study was aimed to evaluate the productivity of Heliconia psittacorum x Heliconia pathocircinada, cv. Golden Torch, when submitted to different sources of organic manure. The experiment was conducted at Escola Agrotecnica Federal, in Satuba, Alagoas State (Brazil). The experimental design was randomized blocks with 5 replications and 10 treatments: [T.sub.1]) control, without fertilization; [T.sub.2]) mineral fertilizer; [T.sub.3]) farm yard manure; [T.sub.4]) chicken bedding; [T.sub.5]) filter cake; [T.sub.6]) urban garbage compound; [T.sub.7]) farm yard manure + mineral fertilizer; [T.sub.8]) chicken bedding + mineral fertilizer; [T.sub.9]) filter cake + mineral fertilizer; [T.sub.10]) urban garbage compound + mineral fertilizer. The following variables were evaluated: number of the tillers per clump, the beginning of the flowering, number of the flower stem per clump, length of flower stem, diameter of flower stem, length of bract, interval of the flowering, number of leaves per flower stem and leaf area of flower stem. The fertilization organomineral provided a significant increase in the variables: number of tillers per clump, length of flower stem, number of flower stem per clump, length of bract, floral stem, diameter of flower stem and leaf area, contributing also to the precocity harvest and smaller flowering interval, when compared with organic fertilizers and control. Key words: tropical flowers, fertility, tillering, flower stem Este estudo foi realizado com o objetivo de se avaliar a produtividade da Heliconia psittacorum x Heliconia spathocircinada cv. Golden Torch, quando submetida a diferentes fontes de adubacao organica. O experimento foi conduzido na Escola Agrotecnica Federal, no municipio de Satuba, AL. O delineamento utilizado foi em blocos casualizados, com 5 repeticoes e 10 tratamentos ficando os tratamentos assim definidos: [T.sub.1]) Testemunha, sem adubacao; [T.sub.2]) Adubo mineral; [T.sub.3]) Esterco de gado; [T.sub.4]) Cama de frango; [T.sub.5]) Torta de filtro; [T.sub.6]) Composto de lixo urbano; [T.sub.7]) Esterco de gado + adubo mineral; [T8]) Cama de frango + adubo mineral; [T.sub.9]) Torta de filtro + adubo mineral e T10) Composto de lixo urbano + adubo mineral. Avaliaram-se as seguintes variaveis: numero de perfilhos por touceira, inicio da floracao, numero de haste floral por touceira, comprimento da haste floral, diametro da haste floral, comprimento da bractea, intervalo de floracao, numero de folhas por ha
