“…On the other hand, most common plant beneficial bacteria belong to genera: Bacillius, Pseudomonas, Bradyrhizobium, Agrobacterium, Enterobacter, and Burkholderia etc. (Ryu et al, 2004;Maksimov et al, 2011;Wang et al, 2012;Gururani et al, 2013;Akhtar et al, 2015;Belimov et al, 2015;Kanwal et al, 2017;Nadeem et al, 2017;Zhou et al, 2017;Cordero et al, 2018;Ishizawa et al, 2019). These PGPR promote plant growth through either direct or indirect mechanism of action (Nadeem et al, 2014).…”

It has been recognized that cytokinins are plant hormones that influence not only numerous aspects of plant growth, development and physiology, including cell division, chloroplast differentiation and delay of senescence but the interaction with other organisms, including pathogens. Cytokinins are not only produced by plants but are also by other prokaryotic and eukaryotic organism such as bacteria, fungi, microalgae and insects. Notably, cytokinins are produced both by pathogenic and also beneficial microbes and are known to induce resistance in plants against pathogen infections. In this review the contrasting role of cytokinin for the defence and susceptibility of plants against bacterial and fungal pathogen and pest insects is assessed. We also discuss the cross talk of cytokinins with other phytohormones and the underlying mechanism involved in enhancing plant immunity against pathogen infections and explore possible practical applications in crop plant production.

“…survived better in hydrochar and its application significantly enhanced plant growth, nutrients (N and P) uptake, and nodulation under water stressed condition. In a greenhouse experiment, Nadeem et al () observed that synergistic application of biochar inoculated with plant growth promoting rhizobacteria ( Pseudomonas fluorescens ) and compost significantly enhanced the cucumber plant growth under water deficit condition. By applying the poultry litter‐biochar to the sandy clay‐loam soil under a pot experiment, Liang et al () noticed a significant increase in the resistance of fungal and bacterial communities, and also in enzyme activities such as phosphomonoesterase, cellulase, and β‐glucosidase under drought stress.…”

Impact of biochar properties on soil conditions and agricultural sustainability: A review

This review summarizes the influences of pyrolysis conditions and feedstock types on biochar properties and how biochar properties in turn affect soil properties. Mechanistic evidence of biochar's potential for enhancing crop productivity, carbon sequestration, and nutrient use efficiency are also discussed. The review identifies the knowledge gaps, limitations, and future research directions for large‐scale use of biochar. Both pyrolytic parameters and feedstock types are considered to be the main factors controlling biochar properties such as nutrient content, recalcitrance, and pH. Biochar produced at low temperatures may improve nutrient availability and crop yield in acidic and alkaline soils, whereas high‐temperature biochar may enhance long‐term soil carbon sequestration. Biochar can also improve the efficiency of inorganic and organic fertilizers by enhancing microbial functions and reducing nutrient loss, thereby making nutrients more available to plants. Integration of biochar and chemical or organic fertilizers generally provides for better nutrient management and crop yield in most types of soils. Although biochar can improve degraded soils, it is not a panacea; as such, soil‐ and crop‐specific biochar are needed in order to ensure optimum crop yield and agricultural sustainability.

“…Biochar application reduced electrolyte leakage from water-stressed as well as nonstressed cucumber plants (Nadeem et al, 2017). The chlorophyll content and RWC significantly decreased with increasing water deficits; however, biochar application displayed a compensatory effect by improving both these parameters (Nadeem et al, 2017). In a lysimeter experiment, Youssef et al (2018) also reported an increase in chlorophyll content and RWC with biochar application for pea plants exposed to drought stress.…”

“…Electrolyte leakage, measured as electrical conductivity due to effused ions from the leaves, is regarded as an indicator of membrane stability to moisture stress. Biochar application reduced electrolyte leakage from water-stressed as well as nonstressed cucumber plants (Nadeem et al, 2017). The chlorophyll content and RWC significantly decreased with increasing water deficits; however, biochar application displayed a compensatory effect by improving both these parameters (Nadeem et al, 2017).…”

“…A lysimeter experiment revealed that biochar application to sandy soil could enhance the growth, dry matter accumulation, and pod yield of green pea (Pisum sativum L.) plants under low water availability (Youssef et al, 2018). Pine wood biochar application (2% w/w), alone or its combination with compost and/or plant growth promoting rhizobacteria (PGPR), has been reported to be a promising strategy to enhance cucumber plant growth under drought stress (Nadeem et al, 2017). The addition of biochar to pots subjected to water deficit increased the root and shoot fresh weights and length of cucumber plants.…”

Water shortage is one of the major challenges faced by the current agricultural systems worldwide, especially in arid and semi-arid regions. Deficit irrigation (DI), a water-saving strategy of applying less water than crop evapotranspiration (ETc) demands, has been extensively investigated in different crops, including water-intensive vegetables. The DI strategies such as regulated deficit irrigation (RDI) and partial root zone drying (PRD) generally increase water use efficiency (WUE) and have emerged as potential practices to save water for agricultural sustainability. However, in view of the sensitivity of shallow-rooted vegetable crops to water stress, DI is often associated with yield losses. A review of 134 DI reports of vegetable crops revealed significant reductions in yield under all DI levels in 52% of cases and yields statistically similar to those of full irrigation (100% ETc in most cases) under small water deficits in 44% of cases, thereby raising concerns about the sustainability of vegetable production under DI. Biochar, a carbon-rich co-product of pyrolysis of organic matter, is increasingly undergoing study as a soil amendment to mitigate drought stress and is being explored as an additional practice with DI to minimize the yield losses due to water deficits. This work reviews the effects of biochar application on growth, yield, physiology, and WUE of different vegetable crops under DI regimes to determine the potential of biochar and DI used in combination to sustain vegetable productivity in water-limited areas. Overall, the addition of biochar under DI has helped to compensate for yield losses of vegetables and further enhanced WUE. However, field studies investigating long-term soil–biochar interactions that strongly conclude the impact of biochar under moisture stress conditions are lacking.
