“…Mohamed et al [17] also demonstrated the Ag NPs-mediated increase in soluble sugars content of wheat leaves under salt stress. One of the salt-mitigatory mechanisms of some fertilizers is an increasing in soluble sugars content which is reported in P application on potato [25], potassium fertilizer on soybean [84] and Ca 2+ supplementation on Calligonum mongolicum [66].…”

Water salinity is one of the major abiotic stresses, and the use of saline water for the agricultural sector will incur greater demand in the coming decades. Recently, nanoparticles (NPs) have been used for developing numerous plant fertilizers as a smart and powerful form of material with dual action that can alleviate the adverse effects of salinity and provide the plant with more efficient nutrient forms. This study evaluated the influence of calcium phosphate NPs (CaP-NPs) as a soil fertilizer application on the production and bioactive compounds of broad bean plants under salinity stress. Results showed that salinity had deleterious effects on plant yield with 55.9% reduction compared to control. On the other hand, CaP-NPs dramatically improved plant yield by 30% compared to conventional fertilizer under salinity stress. This improvement could be attributed to significantly higher enhancement in total soluble sugars, antioxidant enzymes, proline content, and total phenolics recorded use of nano-fertilizer compared to conventional use under salt stress. Additionally, nano-fertilizer reflected better mitigatory effects on plant growth parameters, photosynthetic pigments, and oxidative stress indicators (MDA and H2O2). Therefore, our results support the replacement of traditional fertilizers comprising Ca2+ or P with CaP-nano-fertilizers for higher plant productivity and sustainability under salt stress.

“…In this respect several kinds of K + and Na + transport systems, such as inward-rectifier shaker K + channel (AKT1), high-affinity K + transporter 5 (HAK5), shaker-like K + outward rectifying channel (SKOR), high-affinity K + transporter 1;5 (HKT1;5), tonoplast Na + /H + antiporter 1 (NHX1), and plasma membrane Na + /H + antiporter 1 (SOS1) have been documented to synergistically regulate ion (K + and Na + ) homeostasis in sugar beet under saline condition (Li et al 2022). Moreover, application of potassium induced salt tolerance as the production of malondialdehyde content and electrolyte leakage decreased, while growth parameters, chlorophyll contents, antioxidant enzymes, gas exchange characteristics, and sugar contents were improved (Parveen et al 2021). Potassium also played an important role in plant water relation under salinity stress and helped the plants to absorb more water to attain turgidity and membrane stability (Abbasi et al 2016).…”

In salt-affected soils, more than one approach should be adopted for minimizing the salinity impacts and enhancing the land productivity. The most effective practices in crop management under saline soil are choosing the plant type and variety and exploiting the best nutrient tactics. Under two soil salinity levels (3.54 and 9.28 dS m−1), representing low and high salinity, respectively), two sugar beet cultivars (Romulus and Francesca) were fertilized with three potassium (K) rates (48, 96, and 144 kg K ha−1), in addition to the check treatment (0 kg K ha−1). During two seasons of 2018/2019 and 2019/2020, treatments were distributed in a split-split plot design based on a randomized complete block arrangement with three replicates. Several physio-biochemical and agronomic traits, as well as leaf mineral contents and juice quality, were assessed. Briefly, findings illustrated that K at a rate of 144 kg ha−1 enhanced cell membrane stability, relative water content, and performance index by 1.17, 1.01, and 2.73 times, respectively, in high salinity soil, compared to low salinity × no K addition. Under high salinity, the addition of 48 and 144 kg K ha−1 recorded the highest values of total phenolic content and total antioxidant activity, respectively. In high salinity soil, K supplying (144 kg ha−1) caused the maximum improvements in gross and white sugar content with a decrease of 42.0% in sodium content and an increase of 35.9% in root yield ha−1. Romulus cultivar fertilized with 144 kg K ha−1 had the maximum relative water content, Fv/Fm, and performance index. Francesca cultivar with 144 kg K ha−1 was the potent combination for increasing total soluble sugars, total phenolic content, total flavonoid content, and total antioxidant activity. Romulus cultivar fertilized with 144 kg K ha−1 was the best practice for improving all agronomic traits of sugar beet. It could be concluded that a high potassium rate, i.e., 144 kg K ha−1, reduced the injury ionic impacts of saline soils along with improving the genetic makeup of sugar beet cultivars, expressed in sugar yield and quality. However, all other attempts for reclamation of the saline soil should be adopted for increasing the potentiality of K fertilizer and enhancing gene expressions of different sugar beet varieties.

“…But the changes in sugar content under salt-induced conditions may vary according to soybean varieties. Tolerant variety may show increased sugar concentrations under salt stress to maintain turgor within plant species [87]. However, yield attributes e.g., branch number, pod number, number of seeds, etc.…”

Soybean is one of the major oil crops with multiple uses which is gaining popularity worldwide. Apart from the edible oil, this crop provides various food materials for humans as well as feeds and fodder for animals. Although soybean is suitable for a wide range of soils and climates, it is sensitive to different abiotic stress such as salinity, drought, metal/metalloid toxicity, and extreme temperatures. Among them, soil salinity is one of the major threats to soybean production and the higher yield of soybean is often limited by salt stress. Salt stress negatively affects soybean seedling establishment, growth, physiology, metabolism, and the ultimate yield and quality of crops. At cellular level, salt stress results in the excess generation of reactive oxygen species and creates oxidative stress. However, these responses are greatly varied among the genotypes. Therefore, finding the precise plant responses and appropriate adaptive features is very important to develop salt tolerant soybean varieties. In this connection, researchers have reported many physiological, molecular, and agronomic approaches in enhancing salt tolerance in soybean. However, these endeavors are still in the primary stage and need to be fine-tuned. In this chapter, we summarized the recent reports on the soybean responses to salt stress and the different mechanisms to confer stress tolerance.
