Some strains of rhizobacteria were investigated for biocontrol efficiency against cucumber green mottle virus (CGMV) in cucumber. Treatment of seeds with three strains of rhizobacteria caused delay in symptom appearance, reduced development of CGMV significantly and enhanced plant growth. Hence, plant growth promoting rhizobacteria could play a major role in reducing of plant virus infections and increasing crop yields.

The growth of plants promoting rhizobacteria (PGPR) has gained widespread importance in agriculture. These are beneficial bacteria found in nature that live actively in plant roots and improve plant growth and increase agricultural productivity.. (PGPR) promoting plant growth shows an important role in the sustainable agricultural industry. The increasing demand for crop production is a major challenge nowadays, with a significant lack of use of synthetic chemical fertilizers and pesticides. The use of PGPR has proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through direct or indirect mechanisms. The mechanisms of PGPR include regulating hormonal and nutritional balance, inducing resistance against plant pathogens, and dissolving nutrients for easy uptake by plants. Furthermore, PGPRs show synergistic and antagonistic interactions with microorganisms within the rhizosphere and in bulk soils, which indirectly increases plant growth rates. There are several bacteria species that act as PGPR. This review summarizes the methodology of PGPR as a bio-fertilizer in agriculture.

It is usually admitted that the chemical fertilizers and pesticides used in modern agriculture create a real environmental and public health problems. The increasing demand for production with a significant reduction of synthetic fertilizers and pesticides use is a big challenge nowadays. The use of plant growth promoting rhizobacteria or PGPR has been proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through either a direct or indirect mechanism. They play an important role to increase in soil fertility, plant growth promotion and suppression of phytopathogens for development of ecofriendly sustainable agriculture. In view of the latest advances in PGPR biotechnology, this paper proposes to do the review on PGPR in rhizosphere and describes the different mechanisms used by PGPR to promote the plants growth and health. In prospect to a healthy and sustainable agriculture, the PGPR approach revealed as one of the best ecofriendly alternatives.

To date, soil salinity becomes a huge obstacle for food production worldwide since salt stress is one of the major factors limiting agricultural productivity. It is estimated that a significant loss of crops (20–50%) would be due to drought and salinity. To embark upon this harsh situation, numerous strategies such as plant breeding, plant genetic engineering, and a large variety of agricultural practices including the applications of plant growth-promoting rhizobacteria (PGPR) and seed biopriming technique have been developed to improve plant defense system against salt stress, resulting in higher crop yields to meet human’s increasing food demand in the future. In the present review, we update and discuss the advantageous roles of beneficial PGPR as green bioinoculants in mitigating the burden of high saline conditions on morphological parameters and on physio-biochemical attributes of plant crops via diverse mechanisms. In addition, the applications of PGPR as a useful tool in seed biopriming technique are also updated and discussed since this approach exhibits promising potentials in improving seed vigor, rapid seed germination, and seedling growth uniformity. Furthermore, the controversial findings regarding the fluctuation of antioxidants and osmolytes in PGPR-treated plants are also pointed out and discussed.

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.
