- Abstract
Salinity can restrict the exploitation of most crops, making agricultural activity economically unfeasible. In this context, the objective of this study was to evaluate the growth, production and quality of endive (Cichorium endivia L.) submitted to different electrical conductivities of water under hydroponic conditions. The experiment was carried out in a randomized block design under five levels of electrical conductivity of waters - ECw (0.34, 1.5, 3.0, 4.5 and 6.0 dS m-1). Plant height (PH), number of leaves (NL), fresh weight (SFM) and dry weight of the shoot (SDM), relative production (RP), water use efficiency at 20 and 25 days after transplanting (DAT) and water consumption (WC) in different periods were evaluated. In general, the highest reductions per unit increase of around 5.93 and 8.53%, ECw were observed for the SFM, and for the SDM, 5.42 and 7.77%, respectively at 20 and 25 DAT. At 25 DAT, under the highest salinity (ECw 6.0 dS m-1) the relative production of SFM and SDM were 52.59 and 58.10%. Water with salinity of up to 6.0 dS m-1 can be used in the cultivation of endive in hydroponics, even with reductions in growth and production, but with no depreciating effects on the visual quality of the product.
