“…This increase in the yield and WUE can be attributed to biochar behavior in the soil, promoting root growth in the soil. Similar results were reported by Obadi et al [ 11 ] in the study on pepper plants grown in greenhouse, which indicated that the addition of biochar improved the WUE and irrigation water savings.…”

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 yield reduction (YR%) and amount of water saved (%) were determined using Equations ( 8) and ( 9), respectively, according to [73]. The WUE improvement was calculated using Equation (10), according to [11]: YR (%) = (yield of control − yield of treatment) yield of control × 100 (8) water saving (%) = (WCC − WCT) WCC × 100 (9) where WCC is the water consumption of the control (m −3 /m −2 ) and WCT is the water consumption of the treatment (m −3 / m −2 ).…”

“…Obadi et al. (2020) conducted a study on sweet pepper ( Capsicum annum L.) to evaluate the effect of BC and compost under partial root‐zone drying irrigation (drought stress). In results, a substantial decline in morphological traits like flowering, fruit set, and vigorous fruit‐bearing stages due to a reduction in the water supply was observed.…”

“…In this regard, organic amendments and PGPR could be a sustainable strategy to improve crop growth and productivity under normal and drought stress conditions. There are many reports about the combined synergistic effect of compost and BC (Adejumo et al., 2020; Bashir et al., 2020; Obadi et al., 2020; Ramzani et al., 2017; Somerville et al., 2019), compost, and PGPR (Armada et al., 2014; Duo et al., 2018; Kanwal et al., 2017; Kazeminasab et al., 2016; Shahzad et al., 2014; Yaseen et al., 2019), BC and PGPR (Ullah et al., 2020; Zafar‐ul‐Hye et al., 2019) and compost, BC and PGPR (Nadeem et al., 2017) under drought stress. The unique mechanisms responsible for plant growth promotion have been discussed in earlier sections (Figures 2–4).…”

Plants are sessile organisms, frequently face unfavourable growth conditions such as drought, salinity, chilling, freezing and high‐temperature stresses, inhibiting growth and development, and ultimately reducing crop productivity. Among these stresses, drought stress has been a major challenge for sustainable crop production and a hot area of research under the current climate change scenario. Organic amendments such as biochar (BC) and compost along with plant growth‐promoting rhizobacteria (PGPR) could be a sustainable strategy to improve crop growth and productivity under drought stress environment. There are several reports about compost, BC, and PGPR application as a single or combined treatment to enhance crop productivity under drought stress. Compost and BC act as conditioners to improve soil physicochemical and biological properties thereby enhancing water holding capacity (WHC) and nutrient retention and availability to the plants. Both BC and compost also serve as carbon sources and suitable environment for PGPR and endogenous microbes to enhance their growth promotion activities under drought stress. PGPR alleviate drought stress via ACC‐deaminase and P‐solubilizing activities, production of phytohormones, secretion of organic acids, acting as biocontrol agents,etc. In the present review, the individual and combined effect of compost, BC, and PGPR to alleviate drought stress in plants has been critically summarized. Moreover, research gaps and future research directions have been identified and discussed in depth.
