“…Other studied traits were not significantly affected by increasing the salinity levels of irrigation water except flowering date during the first season. Similar results was explained by Salem et al, (2017) who clarified that the limitation of plant growth under salinity conditions corresponds to the fact that salinity leads to the accumulation of certain ions and deficiency of other ions and the reduction of external water potential in the cell. Moreover, the decrease in plant growth may be due to interruptions in metabolic activities affected by decreased water absorption and disturbance in water balance (Fahad et al, 2015).…”

Field experiments were conducted during summer seasons of 2018 and 2019 at Soil Salinity Dept., Soil, Water, and Environment Research Institute, Agriculture Research Center, Alexandria Governorate, Egypt, , to investigate the response of five different genotypes of growing melon to three levels of saline irrigation water (500, 2000, 4000 mg/L). The included genotypes were Line Mass Matrouh, local genotype (G1), Line 22 (G2), Line 26 (G3), Line Ideal (G4) and Line New Matrouh (G5). Results indicated that traits of plant length and number of branches/plant were negatively significant affected by salinity treatment (2000, 4000 mg/L) during the two studied growing seasons. While date of flowering and number of fruits/plant were not affected by treatments of saline irrigation water across the two seasons. Line G3 recorded the highest mean value for average fruit weight/plant followed by Line G4. Fruit shape index, total soluble solids and fruit moisture content were also significantly positive affected by different levels of water saline. These results clearly indicated that the evaluated melon genotypes differed in their genetic traits. Among genotypes, G3 and G4 lines showed the highest tolerance to the saline water treatments (2000 , 4000 mg/L) , so we recommend to use these lines either in areas irrigated with saline water or to be integrated in breeding program to produce more salt tolerant hybrid of melon plant that can be used in cultivating areas irrigated with saline water.

“…These results falls in line with the data reported by Mahmoud (2012) on potato plants. The reduction in plant growth under salinity stress conditions is consistent with the fact that salinity induces accumulation of certain ions and deficiency of the others and lowers the external water potential in the cell (Salem et al, 2017). Furthermore, the reduction in plant growing may be due to the interruption in metabolic activities affected by the decrease of water absorption and disturbance in water balance (Fahad et al, 2015).…”

“…Foliar-applied of K-silicate has a more pronounced ameliorative impact on faba bean plants irrigated with saline water [58]. Foliar application of K-silicate is considered the source of potassium and silicon elements that plays a vital role in sustaining and improving a plant's photosynthetic apparatus as a result of enhancing leaves number and area [67]. Foliarapplied of K-silicate regulates the stomatal conductance, promoting ATPase, DNA and RNA synthesis as well as maintains the ionic balance in faba bean leaves irrigated with saline water [68].…”

The continuity of traditional planting systems in the last few decades has encountered its most significant challenge in the harsh changes in the global climate, leading to frustration in the plant growth and productivity, especially in the arid and semi-arid regions cultivated with moderate or sensitive crops to abiotic stresses. Faba bean, like most legume crops, is considered a moderately sensitive crop to saline soil and/or saline water. In this connection, a field experiment was conducted during the successive winter seasons 2018/2019 and 2019/2020 in a salt-affected soil to explore the combined effects of plant growth-promoting rhizobacteria (PGPR) and potassium (K) silicate on maintaining the soil quality, performance, and productivity of faba bean plants irrigated with either fresh water or saline water. Our findings indicated that the coupled use of PGPR and K silicate under the saline water irrigation treatment had the capability to reduce the levels of exchangeable sodium percentage (ESP) in the soil and to promote the activity of some soil enzymes (urease and dehydrogenase), which recorded nearly non-significant differences compared with fresh water (control) treatment, leading to reinstating the soil quality. Consequently, under salinity stress, the combined application motivated the faba bean vegetative growth, e.g., root length and nodulation, which reinstated the K+/Na+ ions homeostasis, leading to the lessening or equalizing of the activity level of enzymatic antioxidants (CAT, POD, and SOD) compared with the controls of both saline water and fresh water treatments, respectively. Although the irrigation with saline water significantly increased the osmolytes concentration (free amino acids and proline) in faba bean plants compared with fresh water treatment, application of PGPR or K-silicate notably reduced the osmolyte levels below the control treatment, either under stress or non-stress conditions. On the contrary, the concentrations of soluble assimilates (total soluble proteins and total soluble sugars) recorded pronounced increases under tested treatments, which enriched the plant growth, the nutrients (N, P, and K) uptake and translocation to the sink organs, which lastly improved the yield attributes (number of pods plant−1, number of seeds pod−1, 100-seed weight). It was concluded that the combined application of PGPR and K-silicate is considered a profitable strategy that is able to alleviate the harmful impact of salt stress alongside increasing plant growth and productivity.
