“…3C and Table 5). A similar pattern of results was obtained, by Saidmuradi et al [93] where they found that salinity stress reduced K + uptake by plants, but maintaining adequate K + levels in plants mitigated adverse effects of salinity [94,95]. Under salinity stress condition, the content of Na + in leaves decreased by application of Kh (HA) treatments and their combination which also led to increased K + content in leaves, [3], (Fig.…”

Background Enriching the soil with organic matter such as humic acid and fulvic acid to increase its content of available nutrients, improve the chemical properties of the soil and increase plant growth as well as grain yield. Under saline soil conditions a field experiment was carried out for studied the effects of treatment by twelve combinations from adding of humic acid (HA) or fulvic acid (FA) or without adding (control), with four ratios of recommended dose (RDP) of phosphorus fertilizer on some agronomic traits, grain yield, and nutrients uptake in barley, to appraise the beneficial effects of these combinations to improve plant growth, N, P, and K uptake, grain yield, and its components under salinity stress. Results The findings exposed that the treatments HA + 100% RDP (T1), HA + 75% RDP (T2), FA + 100% RDP (T5), HA + 50% RDP (T3), and FA + 75% RDP (T6), improved number of spikes/plant, 1000-grain weight, grain yield/ha, harvest index, the amount of uptake of nitrogen (N), phosphorous (P) and potassium (K) in straw and grain. The increase percentage 64.69, 56.77, 49.83, 49.17, and 44.22% in the first season, and 64.08, 56.63, 49.19, 48.87, and 43.69% in the second season, for grain yield over the control. Meanwhile, the increase was 22.30, 16.42, 11.27, 10.78, and 7.11% in the first season, and 22.17, 16.63, 11.08, 10.84, and 6.99% in the second season, for grain yield compared with the recommended dose. Therefore, it is recommended to treat the soil with humic acid or foliar application the plants with fulvic acid in addition to phosphate fertilizer with one of the following treatments: HA + 100% RDP (T1), HA + 75% RDP (T2), FA + 100% RDP (T5), HA + 50% RDP (T3), and FA + 75% RDP (T6) under salinity conditions. Conclusions The result of the use of organic amendments was an increase in the tolerance of barley plant to salinity stress, which was evident from the improvement in the different traits that occurred after the treatment using treatments that included organic amendments (humic acid or fulvic acid).

“…In line with our findings, Zhang et al (2021b) highlighted that MT enhanced the growth of sugar beet, i.e., leaf area, fresh and dry weights in addition to increasing chlorophyll content under salinity stress. These responses may be due to decreased ROS generation (caused by salinity stress) and MDA accumulation as well as increased antioxidant enzyme activities in stressed plants (Han et al, 2017;Farag et al, 2022;El-Beltagi et al, 2023b) and intensive ROS accumulation sites in chloroplasts caused by the imbalance between electron transport rates and СО 2 fixation. Generation of ROS leads to protein degradation and pigment bleaching.…”

“…Additionally, it inhibits the activity of enzymes, which results in chlorophyll degradation and photosynthetic inhibition (Fatma et al, 2016). The visible harmful impacts of salinity include decreases of leaf area, necrosis and abscission (Fariduddin et al, 2019). Additionally, salt stress has a considerable effect on the ion uptake of essential nutrients and causes impaired growth promotion, thus resulting in obstacles to normal growth and development (Elkelish et al, 2019;Alnusairi, 2021;Youssef et al, 2021;El-Taher et al, 2022;Abdelkader et al, 2023aAbdelkader et al, , 2023b.…”

Salinity is one of the most important abiotic stresses that significantly decreases the productivity of agricultural crops. Melatonin (MT) acts as an antioxidant and plays a vital role in overcoming oxidative damage. However, previous literature has not provided a clear understanding of the impact of MT on lettuce plants under salinity stress. So, we investigated the effect of exogenous MT at 0 μM, 50 μM, 100 μM and 150 μM on lettuce plants grown under salinity stress (0 mM NaCl, 50 mM NaCl and 100 mM NaCl) with respect to vegetative growth, photosynthetic pigments, relative water content (RWC), electrolyte leakage (EL), malondialdehyde (MDA), H2O2, O2 •- and antioxidants enzymes. Results showed that NaCl stress significantly decreased vegetative growth, RWC and photosynthetic pigments and in contrast enhanced dry matter, EL, MDA, H2O2, O2 •-, Na+, Cl-, peroxidase (POD), superoxide dismutase (SOD) and glutathione reductase (GR) of lettuce plants compared to non-salinized control. The results demonstrated that under salinity conditions, foliar applications of MT significantly alleviated the harmful effects of salinity and increased number of leaves, leaf area, fresh weight, chlorophyll (a), chlorophyll (b), total chlorophyll, carotenoids and RWC in comparison to untreated plants (control). Meanwhile, dry matter, MDA, H2O2, O2 •-, Na+, Cl-, POD, SOD and GR were significantly decreased compared to untreated lettuce plants. In this respect, spraying MT at 150 μM ranked the first, then 100 μM, compared to the lower concentration (50 μM). In conclusion, MT application can be used to alleviate harmful effects of salinity stress.

“…Saidimoradi et al [ 38 ] obtained a similar pattern of results, finding that salinity stress reduced the uptake of K + by strawberry plants. Maintaining adequate K + levels in plants could mitigate adverse salinity conditions [ 11 , 81 , 82 ]. Under the saline condition, our results show that Na + content in leaves was decreased, whereas Kh and SA treatments and their combination increased K + content ( Figure 4 C,D).…”

In the current study, we investigated the effect of potassium humate (Kh) and salicylic acid (SA) in mitigating the salinity stress of common bean plants. Common bean seedlings were treated with 0.2 g/L SA as a foliar application and 0.3 g/L Kh as a soil application individually or in combination. After 7 days of germination, plants were treated with 50 mM NaCl and normal water as a control. Our results indicate that salt treatment reduced the plant growth (fresh and dry shoots and roots), leaf pigments (total chlorophyll and carotenoids), ascorbic acid (AA), glutathione (GSH), and potassium (K) contents. On the contrary, proline content; sodium (Na); hydrogen peroxide (H2O2); superoxide anion (O2•−); and antioxidant enzymes, including catalase (CAT), peroxidase (POX), and superoxide dismutase (SOD), were increased by saline stress. However, applying either individual Kh and SA or their combination stimulated seedling growth under salinity stress by increasing growth parameters, leaf pigment contents, AA, GSH, proline content, K content, and antioxidant enzymes compared with the control. Additionally, Na content, H2O2, and O2•− were reduced by all applications. The application of the Kh (0.3 g/L) + SA (0.2 g/L) combination was more effective than using the individual compounds. In conclusion, applications of Kh + SA can mitigate salt stress and improve the seedling growth of common bean.
