“…The highest values for the leaf pigments traits were recorded in plants treated with biochar and irrigated with fresh water under 100% of ETc compared to plants irrigated with saline water, particularly under the highest water deficit of 40% ETc, which recorded the lowest values ( Table 5 ). Similar results were reported by Nadeem et al [ 54 ], Kanwal et al [ 55 ], and Karabay et al [ 39 ], namely that the addition of biochar increased the chlorophyll content under salt stress and drought conditions. Additionally, Kul et al [ 26 ] found that the application of 5% biochar improved the yield and growth characteristics of tomatoes grown under salinity conditions.…”

The use of saline water under drought conditions is critical for sustainable agricultural development in arid regions. Biochar is used as a soil amendment to enhance soil properties such as water-holding capacity and the source of nutrition elements of plants. Therefore, the experiment was conducted to evaluate the effects of biochar application on the morpho-physiological traits and yield of tomatoes under combined salinity and drought stress in greenhouses. There were 16 treatments consist two water quality fresh and saline (0.9 and 2.3 dS m−1), three deficit irrigation levels (DI) 80, 60, and 40% addition 100% of Evapotranspiration (ETc), and biochar application by rate 5% (BC5%) (w/w) and untreated soil (BC0%). The results indicated that the salinity and water deficit negatively affected morphological, physiological, and yield traits. In contrast, the application of biochar improved all traits. The interaction between biochar and saline water leads to decreased vegetative growth indices, leaf gas exchange, the relative water content of leaves (LRWC), photosynthetic pigments, and yield, especially with the water supply deficit (60 and 40% ETc), where the yield decreased by 42.48% under the highest water deficit at 40% ETc compared to the control. The addition of biochar with freshwater led to a significantly increased vegetative growth, physiological traits, yield, water use efficiency (WUE), and less proline content under all various water treatments compared to untreated soil. In general, biochar combined with DI and freshwater could improve morpho-physiological attributes, sustain the growth of tomato plants, and increase productivity in arid and semi-arid regions.

“…The biochar enhanced the soil water status and diluted the ion concentration under salinity stress, maintaining a suitable environment for plant growth [ 38 ]. Moreover, the addition of biochar improved vegetative growth due to the reduction in oxidative and osmotic stresses [ 39 ].…”

“…The increase in the chlorophyll content in leaves of quinoa plants grown with Bc can be explained by the increased accessibility of nitrogen in the soil and, consequently, higher nitrogen availability and higher chlorophyll content in leaves [ 57 , 58 , 59 , 60 , 61 , 62 ]. Additionally, it was reported that the saline application significantly reduced total leaf chlorophyll and also the carotenoid content in beans, and that the Bc amendments applied at 5 t ha −1 and 15 t ha −1 to the topsoil mitigated these negative effects [ 63 ]. In agreement with the previously published studies, the Bc-induced increase in the chlorophyll content in quinoa leaves was accompanied by an increase in CO 2 fixation (A net : from 6.36 to 12.51 CO 2 µmol m −2 s −1 ) [ 64 , 65 , 66 , 67 ].…”

In agriculture, soil amendments are applied to improve soil quality by increasing the water retention capacity and regulating the pH and ion exchange. Our study was carried out to investigate the impact of a commercial biochar (Bc) and a superabsorbent polymer (SAP) on the physiological and biochemical processes and the growth performance of Chenopodium quinoa (variety ICBA-5) when exposed to high salinity. Plants were grown for 25 days under controlled greenhouse conditions in pots filled with a soil mixture with or without 3% Bc or 0.2% SAP by volume before the initiation of 27 days of growth in hypersaline conditions, following the addition of 300 mM NaCl. Without the Bc or soil amendments, multiple negative effects of hypersalinity were detected on photosynthetic CO2 assimilation (Anet minus 70%) and on the production of fresh matter from the whole plant, leaves, stems and roots (respectively, 55, 46, 64 and 66%). Moreover, increased generation of reactive oxygen species (ROS) was indicated by higher levels of MDA (plus 142%), antioxidant activities and high proline levels (plus 311%). In the pots treated with 300 mM NaCl, the amendments Bc or SAP improved the plant growth parameters, including fresh matter production (by 10 and 17%), an increased chlorophyll content by 9 and 13% and Anet in plants (by 98 and 115%). Both amendments (Bc and SAP) resulted in significant salinity mitigation effects, decreasing proline and malondialdehyde (MDA) levels whilst increasing both the activity of enzymatic antioxidants and non-enzymatic antioxidants that reduce the levels of ROS. This study confirms how soil amendments can help to improve plant performance and expand the productive range into saline areas.

“…This observation is in accordance with previous studies by Zhang et al (2020) and Cong et al (2023) on soybean and maize plants, respectively. Contrarily, the findings of Ufkay et al (2021) indicate that a heightened application rate of biochar may exacerbate the detrimental impacts of salinity on soil. This exacerbation is attributed to the cumulative levels of soil EC, which can cause a transition from beneficial to detrimental conditions for plant growth.…”

The production of olive mill solid waste (OMSW) raises concerns due to its toxicity and negative environmental impact. However, by utilizing pyrolysis, OMSW can be converted into biochar, a carbon-rich material that detoxifies the waste and preserves its nutrient content. The OMSW-based biochar possesses alkaline properties (pH 9.6), low electrical conductivity (EC), high cation exchange capacity (CEC), a porous surface morphology, various surface functional groups, and high mineral content. This study assessed the influence of two concentrations (5% and 10%) of OMSW-based biochar on wheat plants' growth biomarkers and physiological characteristics subjected to salt stress conditions (150 mM NaCl). Findings of the study revealed that salt stress had deleterious effects on various parameters, including shoot height, fresh and dry weights of shoots and roots, relative water content (RWC%), membrane stability index (MSI%), photosynthetic pigments, and photosynthetic parameters such as the coefficient of the effective quantum yield of photochemical energy conversion of PSII (ØPSII), photochemical quenching (qP), and photochemical efficiency of PSII (Fo, Fm, Fv/Fo, and Fv/Fm). Furthermore, the levels of lipid peroxidation (MDA), hydrogen peroxide (H2O2), superoxide dismutase (SOD), and peroxidase (POD) activities significantly increased in stressed plants. On the other hand, applying both concentrations of OMSW-based biochar effectively improved the overall performance of wheat plants, irrespective of the presence of salinity. OMSW-based biochar is a promising strategy for promoting wheat growth in salt-stressed soil by improving various growth parameters and mitigating plant oxidative stress.
