-Flower production in semi-hydroponic systems is a profitable alternative for generating income in communities of small farmers in the semiarid region of Brazil. This is because such a system of cultivation relates aspects of the climate, water and soil of the region, favoring the production of crops. In this work, the use of wastewater as a source of water and nutrients was studied, renewed at four time intervals (daily and every two, three and four days), and of three growth substrates (coconut fiber, sand and sugarcane bagasse), in the production and post-harvest period of sunflowers. These treatments were distributed in a completely randomised design and analysed in a 4 x 3 factorial with three replications, giving a total of 36 experimental units. It was found that plants under the wastewater renewal of every four days demonstrated characteristics compatible with commercial standards for sunflowers, if grown in sand or coconut fiber.Key words: Helianthus annus L..

Neste trabalho estudou-se a utilização da água residuária como fonte de água e nutrientes renovado em quatro intervalos de tempo (diariamente, a cada dois, três e quatro dias) e três substratos de cultivo (fibra de coco, areia e bagaço de cana de açúcar) na produção e pós-colheita de flores de girassol; estes tratamentos foram distribuídos em um delineamento inteiramente casualizado, analisado em esquema fatorial 4 x 3, com três repetições, totalizando 36 unidades experimentais. Verificou-se que as plantas sob renovação da água residuária a cada quatro dias apresentaram características compatíveis com o padrão comercial para flores de girassol, desde que cultivadas em fibra de coco ou areia.

“…Uma das maneiras para aumentar a oferta de água disponível para a irrigação é a utilização da água de forma racional (SANTOS JÚNIOR et al, 2013), bem como o reuso de água provenientes de outras atividades (MEDEIROS et al, 2010). Uma fonte hídrica que vem ganhando destaque são as águas cinza provenientes dos efluentes de chuveiros, lavatórios, pias de cozinha, tanques e máquinas lava roupas.…”

“…The way to increase availability of sources of water to irrigation is to rationalize its use (Santos Júnior et al, 2013), as well as to reuse water from different activities (Medeiros et al, 2010). The reuse of wastewater on forage production comes as a strategy to sustainable management of water, to reduce future problems of water scarcity.…”

The present work aimed to analyze the effects of the application of dilutions of treated gray water (TGW) in well water (WW) on growth and production of millet cv. Ceará (Pennisetum glaucum). The experiment was carried out in a greenhouse, on the department of agronomic and forestry sciences, at the Federal Rural University of the Semi-Arid (UFERSA), Mossoró, RN, Brazil. The experimental design was randomized blocks with five treatments and six replications, totaling thirty plots. The experiment was carried out in vases with volume of 25L containing four plants per vase. The treatments consisted in five dilutions of TGW in WW: T1—100% WW plus 0% TGW; T2—75% WW plus 25% TGW; T3—50% WW plus 50% TGW; T4—25% WW plus 75% TGW and T5—0% WW plus 100% TGW. During the experiment it was analyzed the attributes of plant height, number of tillers, number of leaves, stem diameter and total fresh and dry matters. With the results, it was observed that the exclusive irrigation with TGW (T5) promoted better millet development. As the concentrations of TGW increased in dilutions, also increased plant height, number of leaves and tillers. The rise in the number of leaves is associated to the rise in height and tillers, and those are associated to the rise in stem diameter and fresh matter, resulting in better accumulations of dry matter and showing the viability of gray water use to improve forage production and increasing potable water availability to multiple uses.
