Reuse of brackish water from desalination units in agriculture will reduce the environmental impacts resulting from disposal in the soil and groundwater, thus reflecting positively in reducing costs. The purpose of this study was to evaluate the impact of reusing brackish water from a small water desalination unit as amended to morphology and productivity of salvia plants during the three growing seasons of 2014–2016. Brackish water from desalination treatment plants was used in hydroponic systems with three concentrations (10, 25 and 50 mM). Growth parameters (number of branches per plant, plant height (cm) and herbage yield weights (g m‾²)) and ion concentration percentage in the herbage of sage (Salvia officinalis L.) during three growing seasons 2014–2016 were measured. Results revealed that lateral branches per plant, plant height and dry weight of herbage were negatively affected by brackish water and decreased by 6, 8 and 10%, respectively, compared to control. In addition, the concentration of ions in herbage decreased by 35 and 20% for nitrogen, phosphorus and potassium, respectively. We conclude from this study that irrigating sage plants using rejected water from desalination plant units leads to a decrease in morphological characteristics compared to non-saline water, but as an economic option this type of water can be used in agriculture to reduce the environmental impacts of disposal of this water.

在水培系统中使用微咸水以低成本生产鼠尾草（Salvia officinalis L.）*

在农业中重复利用海水淡化装置的微咸水将减少因处理土壤和地下水而对环境造成的影响，从而在降低成本方面产生积极影响。本研究的目的是评估在 2014 年至 2016 年三个生长季节中重新利用小型海水淡化装置的咸水对丹参植物形态和生产力的影响。来自海水淡化处理厂的微咸水用于三种浓度（10、25 和 50 mM）的水培系统。鼠尾草^（ Salvia officinalisL.) 在 2014-2016 年的三个生长季节进行了测量。结果表明，与对照相比，微咸水对每株侧枝、株高和草本干重的负面影响分别降低了 6%、8% 和 10%。此外，草本植物中的氮、磷和钾离子浓度分别降低了 35% 和 20%。我们从这项研究中得出结论，与非盐水相比，使用来自海水淡化装置的废弃水灌溉鼠尾草会导致形态特征下降，但作为一种经济选择，这种水可以用于农业以减少对环境的影响处理这些水。
