Abstract	1 RESUMO O uso de agua residuaria e uma pratica com grandes vantagens, sobremaneira no aporte de nutrientes as plantas, fator que contribui para um crescimento mais rapido. O girassol ( Helianthus annuus L.) e uma planta de interesse ornamental e decorativo, por sua beleza incomparavel. Buscou-se, com esta pesquisa, estudar o crescimento de genotipos de girassol ornamental, irrigados com agua residuaria domestica e de abastecimento. O experimento foi conduzido em ambiente protegido da Universidade Federal de Campina Grande, PB, em delineamento experimental de blocos casualizados, em esquema fatorial 4 x 2, com 3 repeticoes, sendo 4 genotipos de girassol (EMBRAPA 122/V2000 – G 1 , Sol Noturno – G 2 , Sol Vermelho – G 3 e Debilis Creme – G 4 ) e 2 tipos de agua (agua de abastecimento – A 1 e agua residuaria tratada oriunda de esgoto domestico – A 2 ). O uso da agua residuaria, associado em sistema orgânico de cultivo, proporcionou os melhores resultados medios de crescimento dos genotipos estudados e, dentre os ornamentais, se destacou o Sol Noturno, com o maior crescimento. A variedade Debilis Creme se destacou no acumulo de fitomassa sob irrigacao com agua de abastecimento, assim como a Sol Noturno irrigada com agua residuaria, porem este fato se da devido as potencialidades individuais de cada uma delas.

GROWTH OF ORNAMENTAL SUNFLOWERS IRRIGATED WITH TREATED WASTEWATER UNDER ORGANIC PRODUCTION 2 ABSTRACT The use of wastewater is a practice with great advantages, especially in the supply of nutrients, a factor that contributes to faster growth. The sunflower ( Helianthus annuus L.) is an ornamental plant with decorative interest, for its stunning beauty. The objective of this research was to study the growth of sunflower genotypes for cutting irrigated with domestic wastewater and supply water. The experiment was conducted in a greenhouse belonging to the Universidade Federal de Campina Grande, PB, in randomized block in a 4 x 2 factorial design with 3 replications utilising 4 sunflower genotypes (EMBRAPA 122 V2000 – G 1 , Sol Noturno – G 2 , Sol Vermelho – G 3 and Debilis Creme – G 4 ) and 2 types of water (supply water – A 1 and treated wastewater originating from domestic sewage – A 2 ). The use of wastewater under organic production provided the best mean results of growth for the studied genotypes and among the ornamental s, the Sol Noturno highlighted, with the maximum growth , and the Debilis Creme , with the least growth. T he Debilis Creme genotype was the one that produced more accumulation of biomass under supply water treatment and the Sol Noturno when the wastewater was used but these facts occurred because of the individual potencialities of each genotype. Keywords: Helianthus annuus L.; o rnamental flowers; wastewater reuse
