Abstract. The main goal of the study is to evaluate the effectiveness of salt-tolerant halophyte species on saline soils and their use as salt-tolerant plants. Experimental studies were carried out in the special greenhouse Horto of the University of the Algarve on the example of halophyte species (Tetragonia tetragonioides and Portulaca oleracea) and salt-tolerant plants (Lactuca sativa, L). Experimental studies of the effect of soil salt on germination, total yield and mineral composition of halophytic species and salt-tolerant crops were carried out. Salinity level (NaCl: (T1, 5 dS-1); T2, 9.8 dS-1; and T3, 20 dS-1) and control treatment (T0, 0.6 dS-1). Both types of halophytes have shown the ability to sequester salts (ions), which negatively affects the productivity of plants grown on saline soils. The results showed that the above species of halophytes contributed to the improvement of the quality and productivity of the salt-tolerant crop. Thus, this method has proven to be an environmentally friendly means of preventing salinization and making agricultural systems sustainable. Thus, these two species can control soil salinity and increase soil fertility, and can also be used as food crops.
