“…isolated from barley and tomato have also been demonstrated to solubilize Zn in vitro [194]. Zinc solubilizing abilities and increased Zn uptake following inoculation of rice plants by Pseudomonas strains [195], soybean and wheat by B. aryabhattai [196], maize by Bacillus strains [197], wheat by Serratia liquefaciens, S. marcescens, and B. thuringiensis [198] and recently in rice by several ZSB [199] have similarly been demonstrated. It is proposed that the use of such ZSB in the field can result in increased Zn uptake by plants, and subsequently, improved growth and yield [200].…”

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.

“…Although chemical Zn fertilizers are often employed to augment these deficits at the recommended rates of approximately 5 kg ha −1 Zn, However, synthetic fertilizers are costly and do not readily get converted into plant-usable forms (Montalvo et al, 2016). Recent literature advances in rhizobacterial Zn solubilization (e.g., Joshi et al, 2013;Hussain et al, 2015;Kamran et al, 2017;Perumal et al, 2019) suggest that the field application of ZSB in the can increase Zn uptake by plants, and subsequently, improve their growth and yields. In an investigation by Naz et al (2016), Pseudomonas, Azotobacter, Azospirillum, and Rhizobium species were shown to significantly enhance Zn uptake in wheat.…”

“…In India, Goteti et al (2013) bacterized potted maize seeds with Zn-solubilizing Pseudomonas that significantly enhanced Zn uptake and concentration. Reports also exist for the Zn solubilizing abilities and increased Zn uptake following inoculation of wheat by Pseudomonads (Joshi et al, 2013), maize by Bacillus (Hussain et al, 2015), wheat and soybean by B. aryabhattai (Ramesh et al, 2014), and rice by several ZSB (Perumal et al, 2019).…”

Recent decades have witnessed increased agricultural production to match the global demand for food fueled by population increase. Conventional agricultural practices are heavily reliant on artificial fertilizers that have numerous human and environmental health effects. Cognizant of this, sustainability researchers and environmentalists have increased their focus on other crop fertilization mechanisms. Biofertilizers are microbial formulations constituted of indigenous plant growth-promoting rhizobacteria (PGPR) that directly or indirectly promote plant growth through the solubilization of soil nutrients, and the production of plant growth-stimulating hormones and iron-sequestering metabolites called siderophores. Biofertilizers have continually been studied, recommended, and even successfully adopted for the production of many crops in the world. These microbial products hold massive potential as sustainable crop production tools, especially in the wake of climate change that is partly fueled by artificial fertilizers. Despite the growing interest in the technology, its full potential has not yet been achieved and utilization still seems to be in infancy. There is a need to shed light on the past, current, and future prospects of biofertilizers to increase their understanding and utility. This review evaluates the history of PGPR biofertilizers, assesses their present utilization, and critically advocates their future in sustainable crop production. It, therefore, updates our understanding of the evolution of PGPR biofertilizers in crop production. Such information can facilitate the evaluation of their potential and ultimately pave the way for increased exploitation.
