“…The abiotic stresses reduced the chlorophyll molecule content, which could indicate chloroplast ultrastructure degradation [28]. In contrast, seed treatment and foliar application of melatonin increased the chlorophyll content compared to unsprayed control, indicating that melatonin could maintain the ultrastructure of chloroplasts under abiotic stresses [29][30][31][32].…”

Mung bean, a legume, is sensitive to abiotic stresses at different growth stages, and its yield potential is affected by drought and high-temperature stress at the sensitive stage. Melatonin is a multifunctional hormone that plays a vital role in plant stress defense mechanisms. This study aimed to evaluate the efficiency of melatonin under individual and combined drought and high-temperature stress in mung bean. An experiment was laid out with five treatments, including an exogenous application of 100 µM melatonin as a seed treatment, foliar spray, and a combination of both seed treatment and foliar spray, as well as absolute control (ambient condition) and control (stress without melatonin treatment). Stresses were imposed during the mung bean’s reproductive stage (31–40 DAS) for ten days. Results revealed that drought and high-temperature stress significantly decreased chlorophyll index, Fv/Fm ratio, photosynthetic rate, stomatal conductance, and transpiration rate through increased reactive oxygen species (ROS) production. Foliar application of melatonin at 100 µM concentration enhanced the activity of antioxidant enzymes such as superoxide dismutase, catalase, and ascorbate peroxidase and the concentration of metabolites involved in osmoregulation and ion homeostasis; thereby, it improves physiological and yield-related traits in mung bean under individual and combined stress at the reproductive stage.

“…The HNS biostimulants were between those two groups. Although biostimulants can increase the leaf nutrient content of plants, the concentrations vary depending on the biostimulant and the nutrient itself (Dehkordi et al, 2021;Rady and Rehman, 2016;Wang et al, 2022). The H group was the most correlated with all the root parameters and the commercial biostimulant group (C) was the least (Fig.…”

“…The production of osmolytes as a protective mechanism under salinity stress is mostly linked to EMs and N, and salt stress tolerance ( Iqbal et al., 2015 ; Talaat et al., 2015 ). These osmolytes-mediated osmotic balance, stimulate water uptake, increase RWC, stabilize cellular membranes and proteins against the damaging effect of free radicals ( Semida et al., 2020 ; Wang et al., 2022 ). These findings demonstrated the ameliorative effect of EMs and high N levels on hot pepper plants against salt stress.…”

“…Our data revealed that soil salinity caused a negative influence on hot pepper plants as indicated by increased levels of Na + , and decreased levels of N, P, K + , and Ca 2+ in leaves ( Table 6 ); thus, this might trigger the ionic imbalance, and nutrient deficiency ( Sitohy et al., 2020 ). Nonetheless, EMs + × N 150 or EMs + × N 180 could “correct” these perturbations in ion homeostasis by increasing N, P, K + , and Ca 2+ but decreasing Na + acquisition as another mechanism of salt tolerance by which hot pepper plants use to maintain ion balance and cell turgor ( Wang et al., 2022 ). These favorable impacts on nutrients accumulation in hot pepper could be related to the role of EMs and/or N in increasing cell membrane integrity; thus, increasing selectivity and transport of ions, besides the accumulation of osmotic regulatory compounds ( Table 4 ), and K + ( Table 6 ) for increasing water and nutrients influx ( Talaat et al., 2015 ; Sikder et al., 2020 ).…”

The application of effective microorganisms (EMs) and/or nitrogen (N) have a stimulating effect on plants against abiotic stress conditions. The aim of the present study was to determine the impact of the co-application of EMs and N on growth, physio-biochemical attributes, anatomical structures, nutrients acquisition, capsaicin, protein, and osmoprotectant contents, as well as the antioxidative defense system of hot pepper (Capsicum annum L.) plants. In the field trials, EMs were not applied (EMs-) or applied (EMs+) along with three N rates of 120, 150, and 180 kg unit N ha-1 (designated as N120, N150, and N180, respectively) to hot pepper plants grown in saline soils (9.6 dS m-1). The application of EMs and/or high N levels attenuated the salt-induced damages to hot pepper growth and yield. The application of EMs+ with either N150 or N180 increased the number, average weight and yield of fruits by 14.4 or 17.0%, 20.8 or 20.8% and 28.4 or 27.5%, respectively, compared to hot pepper plants treated with the recommended dose (EMs- × N150). When EMs+ was individually applied or combined with either N150 or N180, increased accumulation of capsaicin were observed by 16.7 or 20.8%, protein by 12.5 or 16.7%, proline by 19.0 or 14.3%, and total soluble sugars by 3.7 or 7.4%, respectively, in comparison with those treated with the integrative EMs- × N150. In addition, the non-enzymatic contents (ascorbate, and glutathione) and enzymatic activities (catalase, superoxide dismutase, and glutathione reductase) of the antioxidant defense systems significantly increased in hot pepper plants treated with EMs+ alone or combined with N150 or N180 under salt stress conditions. Higher accumulation of nutrients (N, P, K+, and Ca2+) along with reduced Na+ acquisition was also evidenced in response to EMs+ or/and high N levels. Most anatomical features of stems and leaves recovered in hot pepper plants grown in saline soils and supplied with EMs+ and N. The application of EMs and N is undoubtedly opening new sustainable approaches toward enhancing abiotic stress tolerance in crops (e.g. hot pepper).
