Vegetable cultivation is a promising economic activity, and vegetable consumption is important for human health due to the high nutritional content of vegetables. Vegetables are rich in vitamins, minerals, dietary fiber, and several phytochemical compounds. However, the production of vegetables is insufficient to meet the demand of the ever-increasing population. Plant-growth-promoting rhizobacteria (PGPR) facilitate the growth and production of vegetable crops by acquiring nutrients, producing phytohormones, and protecting them from various detrimental effects. In this review, we highlight well-developed and cutting-edge findings focusing on the role of a PGPR-based bioinoculant formulation in enhancing vegetable crop production. We also discuss the role of PGPR in promoting vegetable crop growth and resisting the adverse effects arising from various abiotic (drought, salinity, heat, heavy metals) and biotic (fungi, bacteria, nematodes, and insect pests) stresses.

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.

Increasing agricultural crop production, especially onion, can be done by improving the optimal growing environment for plants. Plant roots can be optimized for the absorption of nutrients and water in the process of photosynthesis. One way that can be used is by applying Plant Growth Promoting Rhizobacteria (PGPR). In addition to increasing the content of micro and macro elements in the soil can also support the growth of leek plants obtained by applying Pineapple Liquid Waste (LCN) made using bacterial isolation and can meet the needs of nutrients in plants. This study aims to determine the effect Plant Growth Promoting Rhizobacteria (PGPR) from Apus (Gigantochola apus) bamboo root and Pineapple Liquid Waste (LCN) fertilizer on the growth of leeks (Allium fistulosum L.), then the results of this study are treated as community information in the form of Leaflets. The method used in this study was an experiment using a Completely Randomized Design (CRD) system consisting of 4x4 factorials with 3 replications. Based on the results of calculations and data analysis, the results show that there is an effect of PGPR and LCN on the growth of scallions on the height and number of tillers per scallion plant family, but there is no influence on pseudo stem circumference and wet weight per scallion plant family, and the results of this study can be used as a source of public information in the form of leaflets with an average percentage included in good eligibility criteria.

Plant Growth Promoting Traits

A laboratory experiment was performed to isolate some native rhizobacteria that could be used as bioinoculants for sustainable crop production. A total of 43 rhizobacteria were isolated from undisturbed plant rhizosphere soils of three different locations of Bangladesh and evaluated their plant growth promoting traits, both direct and indirect. The study has screened out isolates on the basis of their phosphorous solubilization and nitrogen (N) fixation. The phosphate solubilization assay in National Botanical Research Institute of Phosphate (NBRIP) medium revealed that 12 bacterial isolates were able to solubilize tricalcium phosphate and the rhizobacteria M25 showed best performance with a PSI of 3.33 at 5 day. Exactly 47% (20 isolates) of the isolated rhizobacteria were able to grow in N-free Winogradsky’s medium, which is an indication of potential N2-fixers. Among the 20 potential N-fixers, 15 were able to grow within 24 hours of incubation indicating that they are more efficient in Nfixation. The present study successfully isolated and characterized 43 rhizobacteria. Some of these isolated rhizobacteria have potential plant growth promoting traits and are potential plant growth promoting rhizobacteria (PGPR) candidate. Considering all plant growth promoting traits, the isolate F37 was the best followed by M6. However, further experiments are needed to determine the effectiveness of these isolates under in vitro and different field conditions to understand the nature of interaction with the plant and environment.Res.

Plant growth-promoting rhizobacteria (PGPR) is a unique group of bacteria that colonize the rhizosphere and roots of plants. They are involved in a plethora of interaction with the host plant and benefit the host plant from nutritional and pathological point of view. The beneficial role of PGPR extends from fixation of atmospheric nitrogen, solubilization of phosphates, siderophore production, synthesis of plant growth regulators, and conferring protection to plants through production of antibiotics and ultimately helping the plants in acquiring resistance. The microbes are also being used for bioremediation purposes and thus act as an eco-friendly cleansing agent. PGPR has gained immense interest in the scientific community and have emerged as a very reliable tool for eco-friendly and sustainable approach for crop production. PGPR is a potent candidate of bioprospection for sustainable use in agriculture and bioremediation process for the overall benefit of mankind.

Rhizosphere and plant-associated microorganisms have been intensely studied for their beneficial effects on plant growth and health. These mainly include nitrogen-fixing bacteria (NFB) and plant-growth promoting rhizobacteria (PGPR). This beneficial fraction is involved in major functions such as plant nutrition and plant resistance to biotic and abiotic stresses, which include water deficiency and heavy-metal contamination. Consequently, crop yield emerges as the net result of the interactions between the plant genome and its associated microbiome. Here, we provide a review covering recent studies on PGP rhizobia as effective inoculants for agricultural practices in harsh soil, and we propose models for inoculant combinations and genomic manipulation strategies to improve crop yield.
