“…Plant probiotics must contain some PGP traits such as the solubilization of elements (P, K, and Zn; Singh et al, 2022), nitrogen fixation (Pandey et al, 2022), production of phytohormones (Kurniawan and Chuang, 2022) aminocyclopropane-1-carboxylate (ACC) deaminase (Santos et al, 2022;Singh et al, 2022), siderophore (Upadhayay et al, 2022a,b), and ammonia (Santos et al, 2022). Production of compounds showing importance in killing pathogens such antibiotics, secretion of enzymes (chitinase, protease/elastase, cellulase, catalase, and β-(1,3)-glucanas; Duhan et al, 2022), volatile compounds (HCN; Vaghela and Gohel, 2022), and also induce systematic resistant in plants against pathogen is the important contribution of plant probiotics (Yin et al, 2022;Chaudhary et al, 2022a). In addition, the ability of plant probiotics to produce exopolysaccharides and biofilms has multiple benefits, including protection from abiotic stress (Banerjee et al, 2019) and desiccation (Mandal et al, 2022), effective root colonization (Naseem et al, 2018), and improved soil aggregation and stabilization (Jhuma et al, 2021).…”

Modern agriculture is primarily focused on the massive production of cereals and other food-based crops in a sustainable manner in order to fulfill the food demands of an ever-increasing global population. However, intensive agricultural practices, rampant use of agrochemicals, and other environmental factors result in soil fertility degradation, environmental pollution, disruption of soil biodiversity, pest resistance, and a decline in crop yields. Thus, experts are shifting their focus to other eco-friendly and safer methods of fertilization in order to ensure agricultural sustainability. Indeed, the importance of plant growth-promoting microorganisms, also determined as “plant probiotics (PPs),” has gained widespread recognition, and their usage as biofertilizers is being actively promoted as a means of mitigating the harmful effects of agrochemicals. As bio-elicitors, PPs promote plant growth and colonize soil or plant tissues when administered in soil, seeds, or plant surface and are used as an alternative means to avoid heavy use of agrochemicals. In the past few years, the use of nanotechnology has also brought a revolution in agriculture due to the application of various nanomaterials (NMs) or nano-based fertilizers to increase crop productivity. Given the beneficial properties of PPs and NMs, these two can be used in tandem to maximize benefits. However, the use of combinations of NMs and PPs, or their synergistic use, is in its infancy but has exhibited better crop-modulating effects in terms of improvement in crop productivity, mitigation of environmental stress (drought, salinity, etc.), restoration of soil fertility, and strengthening of the bioeconomy. In addition, a proper assessment of nanomaterials is necessary before their application, and a safer dose of NMs should be applicable without showing any toxic impact on the environment and soil microbial communities. The combo of NMs and PPs can also be encapsulated within a suitable carrier, and this method aids in the controlled and targeted delivery of entrapped components and also increases the shelf life of PPs. However, this review highlights the functional annotation of the combined impact of NMs and PPs on sustainable agricultural production in an eco-friendly manner.
