“…Macro element levels decreased significantly under drought stress in soybean seedlings, and our results are similar to those of several authors, including those of Arjenaki et al (2012) for wheat plants under drought stress, Ramadan et al (2019) for sunflower plants under salt stress, and Sadak et al (2020) for Moringa oleifera under drought stress. The macro elements decrease might be due to the decline in photosynthetic pigment levels, which is supported by the findings of Hasan et al (2019). In the current study, the application of HBR to droughttreated soybean seedlings restored the macro element levels, possibly due to the increased absorption and accumulation of these elements (Figure 4).…”

“…In soybean plants, the TP and TF levels increased under drought stress, possibly due to augmented activities of enzymes that are thought to be linked with the biosynthesis of these compounds (Bhattacharya et al 2010). Hasan et al (2019) also reported similar results, showing that the TP and TF levels increased in Moringa species under drought stress. TP and TF accumulation in plants provides tolerance against abiotic stress, protects the cell membrane and decreases lipid peroxidation (Potapovich and Kostyuk 2003).…”

“…Drought negatively influences plant growth and yield, especially in drought-prone areas of the world (Hasan et al 2020). The prolongation of drought may lead to critical physiological and developmental changes in plants (Khan et al 2017;Hasan et al 2019). Drought causes various metabolic and physiological abnormalities in plants such as loss of cell turgor, cell shrinkage, photosynthetic reduction, and imbalance in mineral content (Choudhury et al 2017;Dubey et al 2018;Yang et al 2019).…”

Brassinosteroids (BRs) are well recognized for their defensive role in plants under abiotic stress conditions, but 28-homobrassinolide (HBR)-induced tolerance to drought stress has not been reported in soybean (Glycine max L.). The present study investigated the effect of HBR on soybean seedlings under drought stress. Drought stress suppressed growth and photosynthetic systems while increased the proline, glycine betaine (GB), anthocyanin, total phenolic (TP), and total flavonoid (TF) levels in soybean seedlings. HBR restricted reactive oxygen species (ROS) accumulation and decreased the hydrogen peroxide (H 2 O 2) and malondialdehyde (MDA) content by triggering the antioxidant systems. HBR acts as a shield in soybean, protecting the plant against the harmful effects of methylglyoxal (MG) effects by upregulating the enzymes glyoxalase I, (Gly I;15%) and glyoxalase II (Gly II;29.1%) compared to the levels in drought stressed seedlings. Overall, HBR improved drought tolerance in soybean seedlings by modulating osmolytes, the AsA-GSH cycle, and enzyme activities.

“…Additionally, the magnetic technique allows us to use salty water (salt content of 2000 ppm and up to 5000 ppm) efficiently for irrigating crops [ 54 ]. Therefore, Hasan et al [ 63 ] reported that using MW in two Moringa species ( Moringa oleifera Lam. and Moringa peregrina (Forssk.)…”

Crop yield can be raised by establishment of adequate plant stand using seeds with high germination ratio and vigor. Various pre-sowing treatments are adopted to achieve this objective. One of these approaches is the exposure of seeds to a low-to-medium level magnetic field (MF), in pulsed and continuous modes, as they have shown positive results in a number of crop seeds. On the basis of the sensitivity of plants to MF, different types of MF have been used for magnetopriming studies, such as weak static homogeneous magnetic fields (0–100 μT, including GMF), strong homogeneous magnetic fields (milliTesla to Tesla), and extremely low frequency (ELF) magnetic fields of low-to-moderate (several hundred μT) magnetic flux densities. The agronomic application of MFs in plants has shown potential in altering conventional plant production systems; increasing mean germination rates, and root and shoot growth; having high productivity; increasing photosynthetic pigment content; and intensifying cell division, as well as water and nutrient uptake. Furthermore, different studies suggest that MFs prevent the large injuries produced/inflicted by diseases and pests on agricultural crops and other economically important plants and assist in reducing the oxidative damage in plants caused by stress situations. An improved understanding of the interactions between the MF and the plant responses could revolutionize crop production through increased resistance to disease and stress conditions, as well as the superiority of nutrient and water utilization, resulting in the improvement of crop yield. In this review, we summarize the potential applications of MF and the key processes involved in agronomic applications. Furthermore, in order to ensure both the safe usage and acceptance of this new opportunity, the adverse effects are also discussed.

“…belonging to the family Moringaceae is an important source of food and medicine [14]. In our previous studies, Moringa oleifera and Moringa peregrina have shown great potential during drought conditions when treated with MW [14,25]. The Moringa biotype was used in this study, which have both Moringa oleifera and Moringa peregrina characteristics, and it was found in the Al Bahah Region of Saudi Arabia [26][27].…”

The present study assesses the effect of drought stress on the Moringa biotype under magnetized water treatment (MWT). The Moringa biotype seedlings were subjected to drought stress with varying field capacities (FC) viz., control (100% FC), moderate drought stress (MS,50% FC), and severe drought stress (SS, 20% FC). Magnetized water (MW) significantly increased plant height, leaflet number, internode distances, leaf area, dry weight of the leaf, shoot, root of the seedlings and markedly improved the assimilation, transpiration, stomatal conductance, water use efficiency and vapor pressure deficit under drought stress conditions. The maximum quantum efficiency of PSII (Fv/Fm) and maximum chlorophyll fluorescence (Fm) were increased and minimum chlorophyll fluorescence (F 0) in the darkadapted state was decreased under drought stress with MWT. Photosynthetic pigments (Chl a, Chl b, carotenoids) significantly decreased under drought stress, but MW significantly increased them. The MW application in Moringa biotype resulted in a decrease in total phenolic content (TPC) by 19% and 26% under MS and SS conditions, respectively. Malondialdehyde(MDA), hydrogen peroxide(H 2 O 2) and accumulation of proline in leaf were decreased with the prolongation of drought with MW. MW could be
