“…Limited crop production due to the degradation of fertile land will affect the availability of food to a steadily increasing world population. Salinity signi cantly inhibited the leaf number, plant heights and weights, chlorophyll content, photosynthetic parameters, RWC, and relative growth rate on vicia faba seedlings (Wei et al, 2021;Neji et al, 2021;Rajhi et al, 2020). The reasons of the growth inhibition of salinity are: (1) the presence of salt in the soil diminishes the capacity of plant to absorb water and this conducts to trouble in the growth rate and this is assigned to the osmotic or water-de cit effect of salinity; (2) the ionic effects which due to the diffusion of high amounts of salt in the plant tissues will cause the damage of the cells (Parihar et al, 2015;Zhang et al, 2022).…”

The aim of this study was to evaluate the effect of the addition of biochar (0, 2, 5, and 8% designed by C, B2, B5, and B8, respectively) on the single and interactive effects of salinity and drought treatments on the growth of vicia faba plants in alkaline soil. 21 morphological, physiological, and photosynthetic parameters were evaluated. The amendment of biochar, carbon-rich material developed from combustion of biomass under no or limited oxygen supply, in alkaline soil under salinity stress performed positive effects on internal concentration of CO2 (+ 96.16% at B8), transpiration rate (+ 83.79% at B5), stomatal conductance (+ 30% at B2), and net CO2 assimilation (+ 37.84% at B2). Under drought stress, the addition of biochar had no effect on internal concentration of CO2 and the water use efficiency. Under combined conditions, the maximum increase (+ 40%) of internal concentration of CO2 was registered at B5. Also, addition of 2% of biochar (B2) can increase the transpiration rate to + 116%. Biochar was alleviating the effect of combined stress on vicia faba leaves by ameliorating the stomatal conductance to + 58.73% at B2. We, also, noticed that net CO2 assimilation rate increase with the increase of biochar concentration. On the other hand, biochar addition did not have effect on lengths of shoot, roots, and total plants and fresh biomass, spad value, and leaf number. However, the amendment of biochar has slightly ameliorated the electrolyte leakage, protein content, and foliar surface. The pH and the EC of initial and final treatment were also evaluated. The statistical analysis demonstrates that addition of 2% (B2) of biochar can significantly mitigate the negative effect of single effect of salinity and combined salinity drought in alkaline soil. On the other hand, the addition of 5% (B5) of biochar can alleviate the individual effect of drought compared to their respective controls. This result confirms the positive effect of biochar addition in alkaline soils. Thus, a better understanding of biochar addition on physiological basis for faba bean growth under drought and salinity stress in alkaline soil will be beneficial for sustainable agriculture.

“…Previous studies have gained widely insight into faba bean growth and productivity injured by salinity and drought stresses (Hashem et al, 2019;Rajhi et al 2020;Neji et al, 2021). The impact of biochar on mitigating the harmful effect of salinity and drought on plants was well studied (Hafeez et al, 2017;Rezaie et al, 2019).…”

“…In many arid and semi-arid areas, groundwater aquifers are also saline. The trace amount of NaCl in the irrigation water increases the salinity in the arable land and salinity becomes more and more a problem every day (Chandel et al, 2021;Neji et al, 2021;Tolay, 2021).…”

“…Drought and high salinity have negative effects on important parameters such as seed germination, seedling growth, crop yield, food quality, etc. (Kang et al, 2021;Liu et al, 2021;Neji et al, 2021). Seed germination includes the process that begins with the seed's absorption of water and ends with the formation of radicles and is a critical stage in the reproduction of plant species (Jiang et al, 2021).…”

Salinity is an important problem all over the world. The destructive effect of salinity is observed from the seed germination stage. In this study, it was aimed to determine the effect of salinity on seed germination of the medically important Satureja thymbra L., whether pre-treatments are a factor in breaking the salinity stress, and to determine the level of salinity tolerance of this species. In the research, firstly, the seeds were exposed to two pretreatments (80°C (5 minutes) + 10 ppm GA3 (24 hours), 80°C (5 minutes) + 100 ppm GA3 (24 hours)) and then 8 different NaCl concentrations (0.1 g/l, 1 g/l, 2.5 g/l, 5 g/l, 7.5 g/l,10 g/l, 15 g/l and 30 g/l) were tried. Germination seeds were counted every day and the effects of salinity on germination characteristics were investigated. The highest germination percentage (90%) was obtained at 0.1 g/l NaCl after 80°C (5 min.) + 100 ppm GA3 (24 h.) pretreatment. The results showed that the effect of salinity was significant on germination parameters in p < 0.05. Obtained results showed that the highest NaCl concentration at which Satureja thymbra seed could germinate was 10 g/l.

“…Several investigations on the impact of salt on stevia have recently been conducted and found to be influenced by varying degrees of salinity, indicating that this plant is relatively sensitive to salt stress [5][6][7][8][9]. Salt-stressed plants have fewer shoots, smaller dry leaves, and stunted growth, as well as the breakdown of plant pigments such as chlorophyll and carotenoids, which disrupt the photosynthetic machinery and impede overall growth [10,11]. As a result, it is critical to develop a new strategy for increasing plant salinity resistance.…”

The current work sought to investigate the impact of two chemicals (NaCl and Brassinolide) on growth parameters, chlorophyll pigments in stevia shoots cultured under in vitro condition. For this, nodal explants of stevia were cultured for four weeks on MS medium supplemented with 0.2 mg l-1 BAP, Kinetin 0.2 mg l-1 and various concentrations of NaCl (0, 60, 70, 90, 120, 150 mM) and BL (0, 1, 2, 3 4, 5µM) for screening under in vitro condition. Explant treated with NaCl showed reduction with increasing salinity levels in all the studied parameters while explants treated with Brassinolide showed best results in all the studied parameters. From the results, it is concluded that the stevia plant was less impacted by 60mM and 70mM NaCl concentrations when compared to other concentrations of NaCl, but BL increased/improved all the examined parameters when compared to control; 1µM and 2µM concentrations of BL responded the best.
