“…Salt stress negatively correlated with growth parameters such as plant height, accumulation and allocation of fresh and dry biomass, and number of leaves (Fig. 1 , 2 ), which was in line with the previously reported data 71 , 72 . In contrast, salinity increased the root/ shoot fresh mass ratio, tissue density, and biomass allocation to root.…”

Moringa oleifera Lam. is a common edible plant, famous for several nutritional and therapeutic benefits. This study investigates the salt -induced modulations in plant growth, physio-biochemical responses, and antioxidant performance of M. oleifera grown under 0, 50, and 100 mM NaCl concentrations. Results showed that the plant effectively managed moderate salinity (50 mM NaCl) by maintaining succulence, weight ratios, and biomass allocation patterns of both shoot and root with minimal reduction in dry biomass. However, high salinity (100 mM NaCl) remarkably declined all growth parameters. The plant accumulated more Na+ and Cl−, while less K+ under salinity as compared to the control. Consequently, osmotic potentials of both root and leaf decreased under salinity, which was corroborated by the high amount of proline and soluble sugars. Increased level of H2O2 with significantly unchanged membrane fluidity indicating its role in perceiving and managing stress at moderate salinity. In addition, increased activities of superoxide dismutase, and catalase, with increased glutathione and flavonoid contents suggest an integrated participation of both enzymatic and non-enzymatic antioxidant components in regulating ROS. On the other hand, high salinity caused an outburst of ROS indicated by high H2O2, MDA, and electrolyte leakage. As a response, moringa drastically increased the activities of all antioxidant enzymes and contents of antioxidant molecules including ascorbic acid, glutathione, total phenols, and flavonoids with high radical scavenging and reducing power capacities. However, a considerable amount of energy was used in such management resulting in a significant growth reduction at 100 mM NaCl. This study suggests that moringa effectively resisted moderate salinity by modulating physio-biochemical attributes and effectively managing ion toxicity and oxidative stress. Salt stress also enhanced the medicinal potentials of moringa by increasing the contents of antioxidant compounds including ascorbic acid, glutathione, total phenols, and flavonoids and their resulting activities. It can be grown on degraded/ saline lands and biomass of this plant can be used for edible and medicinal purposes, besides providing other benefits in a global climate change scenario.

“…Similar results have been observed in previous studies of Elhindi et al (2016);; Sofy et al (2020) and Ren et al (2020). Also, Farooq et al (2022) revealed that all salinity levels significantly affected the germination and growth parameters of M. oleifera landraces. Soliman et al (2015) pointed out that salinity levels reduced growth parameters and chlorophyll content in M. peregrina.…”

The newly reclaimed soils suffer from some stresses, especially salinity, whether in the soil or irrigation water that severely hinder the growth and production of some crops. A pot experiment was conducted during 2021 and 2022 seasons at Al-Marashda Research Station, Qena, ARC, Egypt to study the influence of silicon and endophytic fungi on germination percentage, survival seedlings rate, biomass and chemical traits of Moringa oleifera under salinity conditions. Pots were filled with sandy soil as substrate and arranged in completely randomized design, having nine treatments, including silicon and endophytic fungi together or alone with two levels of salinity. The two salinity levels were significantly affected the germination and survival percentages, biomass as well as chemical compositions of M. oleifera. However, addition of silicon at 100 mg/ l or endophytic fungus (Chaetomium globosum) at 100 ml, together or alone led to increase germination percentage and survival rate, biomass characters, N, P, K, and total chlorophyll in moringa leaves under saline conditions. The improvement was better with lower salinity level (3 dS m -1 ) compared to the higher one for the 1 st and 2 nd seasons. Application of both silicon and endophytic fungi led to better growth results compared to the individual treatments. Leaves of salt-treated plants without any additives contained high levels of Na + and Clcompared to those treated with saline reducers.

“…For instance, if the concentration of the ions in the soil increases through a salinity increase, the crop productivity may be limited because of poisoning and possible plant death [ 48 ]. Moreover, it may lower the seedling growth rate, resulting in a decrease in crop productivity because of a decreased soil water potential [ 49 , 50 ]. Therefore, the limited salt variability in the results can be interpreted as a potential positive factor in agricultural production.…”

Soil salinity negatively affects plant growth and leads to soil degradation. Saline lands result in low agricultural productivity, affecting the well-being of farmers and the economic situation in the region. The prediction of soil salinization dynamics plays a crucial role in sustainable development of agricultural regions, in preserving the ecosystems, and in improving irrigation management practices. Accurate information through monitoring and evaluating the changes in soil salinity is essential for the development of strategies for agriculture productivity and efficient soil management. As part of an ex-ante analysis, we presented a comprehensive statistical framework for predicting soil salinity dynamics using the Homogeneity test and linear regression model. The framework was operationalized in the context of the Khorezm region of Uzbekistan, which suffers from high levels of soil salinity. The soil salinity trends and levels were projected under the impact of climate change from 2021 to 2050 and 2051 to 2100. The results show that the slightly saline soils would generally decrease (from 55.4% in 2050 to 52.4% by 2100 based on the homogeneity test; from 55.9% in 2050 to 54.5% by 2100 according to the linear regression model), but moderately saline soils would increase (from 31.2% in 2050 to 32.5% by 2100 based on the homogeneity test; from 31.2% in 2050 to 32.4% by 2100 according to the linear regression model). Moreover, highly saline soils would increase (from 13.4% in 2050 to 15.1% by 2100 based on the homogeneity test; from 12.9% in 2050 to 13.1% by 2100 according to the linear regression model). The results of this study provide an understanding that soil salinity depends on climate change and help the government to better plan future management strategies for the region.
