DE ANDRADE, Leandro Oliveira et al. Quality the ornamental sunflowers irrigated with waste and supply waters. Idesia [online]. 2012, vol.30, n.2, pp.19-27. ISSN 0718-3429.

The use of treated wastewater is being practiced in agriculture and tends to be an economical and environmental alternative for flower cultivation, especially for cut flowers, as the final product has no direct contact with the water. The objective of this research was to evaluate the use of this alternative source of irrigation water on the growth of cut sunflower genotypes under an organic system. The trial was carried out in a greenhouse at Universidade Federal de Campina Grande - PB, Brazil, adopting a randomized block design in a 4 x 2 factorial with three replicates and two plants per plot, with 4 genotypes of sunflower (Helianthus annuus L.) (EMBRAPA V2000/122 - G1, Sol Noturno - G2, Sol Vermelho - G3 and Debiblis Crème - G4) combined with 2 irrigation treatments (municipal supply water - A1 and treated sewage wastewater - A2). The treated wastewater was significantly better for the variables plant height, stem diameter, leaf number, external and internal diameter of the capitulum , as well as number of petals. In general the best genotype was Sol Noturno, which stood out particularly after harvest, with the best result for durability.
