“…Yet, some authors have already developed researches on the production of vegetable crops, like coriander (Coriandrum sativum L.) in semiarid conditions under water or saline stress (Ghamarnia et al, 2013;Silva et al, 2013;Hassan & Ali, 2014), with even conventional hydroponic systems (Luz et al, 2012;Rebouças et al, 2013).…”

“…Although widely consumed and important for the economy of this region (Rebouças et al, 2013), many municipalities in the Brazilian semiarid region need to import vegetable crops like coriander from producing centers, and the distance and transport conditions increase the price and decrease the shelf life of the product.…”

“…In Brazil, it is consumed in all the regions, especially its green mass, which is used in the cookery of many typical dishes, and its dry fruits, used as seasonings and in the manufacture of breads, candies, pickles and fine liquors (Rebouças et al, 2013).…”

A B S T R A C TThe increase of water use efficiency in crop production is a clear need in areas with restricted access to this resource and, in these cases, the adoption of forms of cultivation contextualized to local conditions are essential. Thus, the implications of the variation in the amount of seeds per cell (0.5, 1.0, 1.5 and 2.0 g) and spacing between cells (7.0, 10.0 and 15.0 cm) on variables related to consumption and water use efficiency for the production of coriander (cv. Tabocas) in a low-cost hydroponic system, an alternative for semiarid regions, were evaluated. A completely randomized experimental design, analysed in 4 x 3 factorial scheme with three replicates, was adopted, and the data were subjected to analysis of variance at 0.05 probability level. It was found that the reduction in the spacing between cells has a better cost-benefit ratio with respect to water consumption, biomass produced and cost of seeds. Therefore, it is recommended the adoption of a spacing of 7.0 cm between cells and the use of 1.0 g seeds per cell; this configuration promoted efficiency of 81.59 g L -1 in shoot green mass production and total mass of 62.4 g coriander bunches.Eficiência do uso da água na produção do coentro em hidroponia de baixo custo R E S U M O O incremento da eficiência do uso da água na produção das culturas é uma necessidade evidente em regiões com acesso restrito a este recurso e, nesses casos, a adoção de formas de cultivo contextualizadas à realidade local é imprescindível. Neste contexto, avaliou-se as implicações da variação da quantidade de sementes por célula (0,5; 1,0; 1,5 e 2,0 g) e do espaçamento entre células (7,0; 10,0 e 15,0 cm) sobre variáveis relacionadas ao consumo e eficiência do uso da água na produção de molhos de coentro (cv. Tabocas) em um "módulo hidropônico de baixo custo", alternativo para regiões semiáridas. Adotou-se um delineamento experimental inteiramente casualizado analisado em esquema fatorial 4 x 3, com três repetições cujos dados foram submetidos à análise de variância em nível de 0,05 de probabilidade. Verificou-se que a redução dos espaços entre células proporcionou melhor relação custo benefício em relação ao consumo de água, massa produzida e custo de sementes. Recomenda-se, portanto, a adoção de 7,0 cm de espaçamento entre células e a utilização de 1,0 g de sementes célula -1 ; esta configuração proporcionou eficiência de 81,59 g L -1 na produção de massa verde da parte aérea e molhos de 62,4 g de massa total.

“…E-mail: vanies_agronomia@hotmail.com. water used for the irrigation of crops contains high levels of salts, which limit the development of the crops, especially coriander (Rebouças et al, 2013). In addition, most rural producers of vegetables perform irrigations with water collected in superficial reservoirs, which may have high concentration of dissolved salts (Oliveira et al, 2014).…”
