“…The co-inoculation of these microorganisms with synthetic Zn fertilizers increased nutrient concentration and uptake, leading to healthy and quality grains with rich nutrient accumulation in bean cultivars [55]. The indigenous Zn solubilizing bacteria are more effective, with potentially better improvements in different phytohormones than in exogenous ones, and are able to sustainably sustain plant and grain concentrations with higher growth, yield, and soil fertility status [56]. In this way, our study also showed that shoot (Figure 3C) and grain (Table 2) Zn concentrations were improved with co-inoculation of R. tropici + B. subtilis along with 8 kg ha −1 of soil applied Zn.…”

“…In this way, our study also showed that shoot (Figure 3C) and grain (Table 2) Zn concentrations were improved with co-inoculation of R. tropici + B. subtilis along with 8 kg ha −1 of soil applied Zn. The activities and redistribution of different Bacillus strains in rhizosphere Zn pools potentially increased plant Zn availability, growth, and assimilation to the grains of legumes and cereals, allowing them to overcome malnutrition [57].…”

“…The accumulation of Zn in the shoots, grains, and plants of common bean (Figure 3D-G) were improved with soil applied Zn and co-inoculation of R. tropici + B. subtilis bacteria. Both the accumulation and concentration of Zn in plant tissues are directly related to the population, availability, and composition of soil micro-biota in the root rhizosphere [58], which, therefore, with some specific strains, increased Zn availability and uptake [57]. The crops on Zn concentrated soils may uptake a lower concentration of Zn due to its oxides and carbonates [59], which should be potentially increased with root-rhizosphere Zn solubilizing microbes.…”

Enrichment of staple food with zinc (Zn) along with solubilizing bacteria is a sustainable and practical approach to overcome Zn malnutrition in human beings by improving plant nutrition, nutrient use efficiency, and productivity. Common bean (Phaseolus vulgaris L.) is one of a staple food of global population and has a prospective role in agronomic Zn biofortification. In this context, we evaluated the effect of diazotrophic bacterial co-inoculations (No inoculation, Rhizobium tropici, R. tropici + Azospirillum brasilense, R. tropici + Bacillus subtilis, R. tropici + Pseudomonas fluorescens, R. tropici + A. brasilense + B. subtilis, and R. tropici + A. brasilense + P. fluorescens) in association with soil Zn application (without and with 8 kg Zn ha−1) on Zn nutrition, growth, yield, and Zn use efficiencies in common bean in the 2019 and 2020 crop seasons. Soil Zn application in combination with R. tropici + B. subtilis improved Zn accumulation in shoot and grains with greater shoot dry matter, grain yield, and estimated Zn intake. Zinc use efficiency, recovery, and utilization were also increased with co-inoculation of R. tropici + B. subtilis, whereas agro-physiological efficiency was increased with triple co-inoculation of R. tropici + A. brasilense + P. fluorescens. Therefore, co-inoculation of R. tropici + B. subtilis in association with Zn application is recommended for biofortification and higher Zn use efficiencies in common bean in the tropical savannah of Brazil.

“…Zinc is a major plant micronutrient that drives several primary and secondary metabolic processes [181]. Existing reports worldwide show that Zn deficiency is a common problem in most agricultural soils due to nutrient mining during crop harvesting and increased use of NPK fertilizers containing lesser amounts of these micronutrients [182,183]. Synthetic Zn fertilizers are often employed to augment these deficiencies at the recommended rates of approximately 25 kg ha -1 ZnSO4 heptahydrate, (equivalent to 5 kg ha -1 Zn).…”

Nevertheless, these artificial fertilizers are not costeffective and readily get converted into insoluble and non-accessible forms to plants [183,184].…”

The world’s population is increasing and so are agricultural activities to match the growing demand for food. Conventional agricultural practices generally employ artificial fertilizers to increase crop yields, but these have multiple environmental and human health effects. For decades, environmentalists and sustainability researchers have focused on alternative crop fertilization mechanisms to address these challenges, and biofertilizers have constantly been researched, recommended, and even successfully-adopted for several crops. Biofertilizers are microbial formulations made of indigenous plant growth-promoting rhizobacteria (PGPR) which can naturally improve plant growth either directly or indirectly, through the production of phytohormones, solubilization of soil nutrients, and production of iron-binding metabolites; siderophores. Biofertilizers, therefore, hold immense potential as tools for sustainable crop production especially in the wake of climate change and global warming. Despite the mounting interest in this technology, their full potential has not yet been realized. This review updates our understanding of the PGPR biofertilizers and sustainable crop production. It evaluates the history of these microbial products, assesses their present state of utilization, and also critically propounds on their future prospects for sustainable crop production. Such information is desirable to fully evaluate their potential and can ultimately pave the way for their increased adoption for crop production.
