“…The most significant of the different biofertilizers is Rhizobia, which has been found to be involved in the fixation of the environmental N 2 by shaping the knobs of roots that go about as smaller than usual industrial facilities of nitrogen obsession in vegetable plants. Atmospheric nitrogen fixation is completed by the enzyme nitrogenase of Rhizobium with the assistance of nodules, a protein, and moves towards plants with a viable beneficial interaction [347]. Furthermore, supplements, i.e., phosphorus, potassium, calcium, magnesium and even iron amassing were observed [334,[348][349][350][351][352][353].…”

Agricultural sustainability is of foremost importance for maintaining high food production. Irresponsible resource use not only negatively affects agroecology, but also reduces the economic profitability of the production system. Among different resources, soil is one of the most vital resources of agriculture. Soil fertility is the key to achieve high crop productivity. Maintaining soil fertility and soil health requires conscious management effort to avoid excessive nutrient loss, sustain organic carbon content, and minimize soil contamination. Though the use of chemical fertilizers have successfully improved crop production, its integration with organic manures and other bioinoculants helps in improving nutrient use efficiency, improves soil health and to some extent ameliorates some of the constraints associated with excessive fertilizer application. In addition to nutrient supplementation, bioinoculants have other beneficial effects such as plant growth-promoting activity, nutrient mobilization and solubilization, soil decontamination and/or detoxification, etc. During the present time, high energy based chemical inputs also caused havoc to agriculture because of the ill effects of global warming and climate change. Under the consequences of climate change, the use of bioinputs may be considered as a suitable mitigation option. Bioinoculants, as a concept, is not something new to agricultural science, however; it is one of the areas where consistent innovations have been made. Understanding the role of bioinoculants, the scope of their use, and analysing their performance in various environments are key to the successful adaptation of this technology in agriculture.

“…Azospirillum has been found to be colonized in the zone of the roots, and also fixed the nitrogen-free relationship with C4 plants, for example, sorghum, maize, sugarcane, and so forth [347]. This fixes atmospheric N 2 , mineralizes different soil nutrients, iron deposition, and furthermore, favours plant mycorrhiza.…”

“…Through the utilization of beneficial bacteria and fungi, many researchers have created bio-fertilizers that can meet the nutrient needs of crops and boost crop output (Aggani 2013;Palai et al 2021). Biofertilizers are alive or dormant cells administered to soil, seeds or seedlings to lessen salt stress and enhance nutrient availability and uptake from soil (Fasusi, Cruz & Babalola 2021).…”

Salinity has emerged as one of the agricultural plants' most severe environmental stresses. Recently, a plant growth-promoting rhizobacteria (PGPR) is being touted as a means of solving yield and environmental issues worldwide. However, multi-strain salt-tolerant rhizobacteria have a short shelf life due to their structural and cellular components, therefore, they need to be supplemented with a liquid carrier material to serve as a shelter and energy source for the bacteria for longer survival. The present study has been undertaken to develop a liquid biofertilizer formulation from multi-strain salt-tolerant PGPR – UPMR, UPMRE6, and a mixed strain of UPMRB9 and UPMRE6 using an optimum amount of cell protectants, namely glycerol (5 mM), trehalose (10 mM), and polyvinyl pyrrolidone (PVP) at 1%. The shelf-life was assessed through measurements of optical density and bacterial biomass to determine the bacterial population and growth trend at monthly intervals. After three months of incubation, the optical density was the highest in the mixed strain treatment supplemented with trehalose with 1.3% and 2.2% increase relative to the UPMRE6 and UPMRB9, respectively, using the same cell protectants. Similarly, bacterial biomass production was the highest in the mixed strains treatment amended with trehalose (0.025 g/mL), with 13.64% and 38.89% increment followed by UPMRE6 and UPMRB9, respectively. Irrespective of the type of protectants used and PGPR type, the optical density and bacterial biomass generally decreased long incubation period. The results demonstrated that the use of 10 mM trehalose has the potential to extend the bacterial shelf life with the slightest cell loss.
