ABSTRACT
Coriander (Coriandrum sativum L.) is a species appreciated in cooking in several dishes, both the shoot fresh and dry biomass and the seeds, with several benefits for human health. In Brazil, fresh coriander biomass is the main form of commercialization, with the largest production area concentrated in the Northeast region. Due to the scarcity of low-salinity water in this region and different parts of the world, brackish waters have been used to irrigate this species. However, often the water salinity levels employed can limit its growth. In this context, this chapter will address aspects related to the hydroponic cultivation of coriander as an alternative for the efficient use of water and the potential use of brackish waters. In conclusion, it is possible to grow coriander hydroponically with high water salinity levels for biomass production as per commercial standards. Such results are even more promising depending on the strategy used, for example, when brackish waters are used only to replenish the evapotranspiration of coriander during the crop cycle in relation to its exclusive use (preparation of the nutrient solution and replenishment) and/or only for the preparation of the nutrient solution.
