“…Thanks to their ability to accumulate large amounts of salt in their shoots, halophytes are well known for their potential to remediate saline soil, thus allowing the subsequential cultivation of less tolerant crops. Such a feature can be also exploited to improve the productivity of salt-sensitive crops by cultivating them in intercrop systems with halophytes to enable more resilient agriculture systems and taking economic advantages from the simultaneous harvest of the two plant species [11].…”

The increasing salinization of agricultural soils urges us to find alternative and sustainable farming systems in order to allow the exploitation of areas that are otherwise becoming less suitable for conventional crops. Thanks to their adaptation to extreme saline conditions, halophytes are promising plants for resilient farming systems, such as intercropping with glycophytes, to ameliorate their productivity in saline soils. This research aimed to evaluate whether the nutritional profile and the content of some health-promoting compounds of the edible portion of Salicornia europaea were influenced by its cultivation in consociation with tomato plants. Moreover, the antioxidant, antibacterial, and anti-inflammatory properties of S. europaea were studied to characterize its bioactivity. The farming system did not influence the concentration of nutrients and bioactive compounds, except for flavonoids. The antimicrobial and anti-inflammatory properties of Salicornia extract suggested the importance of this halophyte for animal and human health.

Halophytes have also been used as intercrops with watermelon (74), cotton (75), maize (76), and many other crops, as reviewed by (77).

Phytotechnology has traditionally been considered as a tool to remediate contaminated soils. While phytotechnology has been generally defined as the application of science and engineering to study problems and provide solutions involving plants, the practical applications go far beyond restoring contaminated land. This review aims to broaden the way we think about phytotechnologies while highlighting how these living technologies can restore, conserve and regenerate the multiple functions and ecosystem services provided by the soil, particularly in the context of agroecosystems. At first, the main problems of soil degradation in agroecosystems are shortly underlined. Subsequently, the importance of plants and their living roots as engines of restoration are reviewed. This paper demonstrates the importance of root traits and functions for soil restoration. It also demonstrates that plant and root diversity together with perenniality are key component of an efficient soil restoration process. Then, a phytotechnology toolbox which includes three pillars for agroecosystems restoration is presented. The three pillars are agricultural practices and land management (1), rhizosphere engineering (2) and ecological intensification (3). This paper also highlights the importance of developing targeted phytotechnology-based restoration strategies developed from root functions and knowledge of rhizosphere processes. More work is needed to evaluate the potential benefits of incorporating phytotechnology-based restoration strategies in the context of grain or vegetable crop productions as most of the studies for agroecosystem restoration strategies were intended to mimic natural prairies.

“…Furthermore, this perennial succulent shrub could have great potential in the restoration of the vegetation cover (greater or lesser tolerance to salinity could have an important effect on the dominance of plant communities with respect to other plants whose germination is inhibited by high concentrations of salt in the soil), as well as in the reduction of salinity in soils that could later be used for agricultural purposes [49,50]. Furthermore, Arthrocnemum could be used in intercropping systems with other non-halophilic crops of commercial interest, since it could help mitigate the salt stress for sensitive crops, as occurs in the mixed crop of tomato (Lycopersicon esculentum Mill) with various halophytes [68].…”

Background Seed germination and seedling growth constitute the first stage of a plant's life cycle for crop establishment. Arthrocnemum Moq. is a halophyte of the subfamily Salicornioideae (Amaranthaceae), which could be recognized in the foreseeable future as an emerging candidate in applied biosaline agricultural programs, mainly due to the large biomass it represents in coastal and inland saltmarshes, in addition to its interesting nutritional and pharmacological properties. However, to ensure their subsequent use as a crop, it is necessary to optimize their germination through appropriate seed priming treatments. The main goal of this work was to seek the optimization of Arthrocnemum germination process using different pretreatments: exposure to sodium chloride (100 to 1200 mM) in the dark and its subsequent transferred to distilled water separately and together with the combination of pH (5, 7, 9), salinity (0, 100, 200 mM NaCl), and iron conditions (0, 200, 400 µM FeSO4). The experiments were tested on six samples of two different species: A. meridionale (from Tunisia) and A. macrostachyum (from Spain). Results Salinity priming of seeds for 15 days in darkness improved germination percentages by almost 25% at 600 mM NaCl, in both Tunisian and Spanish species. However, keeping seeds at different salt concentrations for 30 days produced higher improvement percentages at lower concentrations in A. meridionale (100–200 mM NaCl), while in A. macrostachyum the highest improvement percentages were obtained at 600 mM NaCl (percentage improvement of 47%). When the dark time period is reduced to 5 days at higher salt concentrations, the greater germination percentages were reached in all the samples at the concentration of 800 mM NaCl, increasing the improvement of germination between 17 and 50%. Finally, the conditions of pH = 7, pretreatment in darkness at 800 mM NaCl and 400 µM or iron, turned out to be an effective medium for seed germination. Conclusions Therefore, before using Arthrocnemum seeds in applied biotechnological programs, a seed priming treatment based on prior exposure to high salt concentrations (600–1000 mM NaCl) is recommended in order to maximize germination percentages.
