“…Microbial PBs have been widely used to enhance crop yield under low-input conditions and mitigate the impacts of climate change on crops [84]. They contain free-living beneficial bacteria and/or fungi listed in the Component Material Categories, number 7 [75,85]. Many bacteria and fungi have been explored for their potential to be applied as biostimulants.…”

Globally, despite the intense agricultural production, the output is expected to be limited by emerging infectious plant diseases and adverse impacts of climate change. The annual increase in agricultural output to sustain the human population at the expense of the environment has exacerbated the current climate conditions and threatened food security. The demand for sustainable agricultural practice is further augmented with the exclusion of synthetic fertilizers and pesticides. Therefore, the application of plant microbiome engineering and (natural) biostimulants has been at the forefront as an environment-friendly approach to enhance crop production and increase crop tolerance to adverse environmental conditions. In this article, we explore the application of microbiome engineering and plant biostimulants as a sustainable approach to mitigating biotic and abiotic stresses and improving nutrient use efficiency to promote plant growth and increase crop yield. The advancement/understanding in plant-biostimulant interaction relies on the current scientific research to elucidate the extent of benefits conferred by these biostimulants under adverse conditions.

“…Plant beneficial microbes (PBMs) (growth-promoting rhizo-microorganisms) are specific fungi or bacteria able to establish "intimate" relationships with plants, leading to plant-growth enhancement, increased nutrient uptake, restoration of soil fertility, and improvement of plant resilience to abiotic and biotic stress [16][17][18][19]. Their application to the soil leads to savings in the use of fertilizers and pesticides with considerable agroecological advantages [20]. The possibility of applying PBMs directly to the seed produces two substantial benefits, viz.…”

Seed quality is an important aspect of the modern cultivation strategies since uniform germination and high seedling vigor contribute to successful establishment and crop performance. To enhance germination, beneficial microbes belonging to arbuscular mycorrhizal fungi, Trichoderma spp., rhizobia and other bacteria can be applied to seeds before sowing via coating or priming treatments. Their presence establishes early relationships with plants, leading to biostimulant effects such as plant-growth enhancement, increased nutrient uptake, and improved plant resilience to abiotic stress. This review aims to highlight the most significant results obtained for wheat, maize, rice, soybean, canola, sunflower, tomato, and other horticultural species. Beneficial microorganism treatments increased plant germination, seedling vigor, and biomass, as well as overcoming seed-related limitations (such as abiotic stress), both during and after emergence. The results are generally positive, but variable, so more scientific information needs to be acquired for different crops and cultivation techniques, with considerations to different beneficial microbes (species and strains) and under variable climate conditions to understand the effects of seed treatments.

“…In this study, the azotobacter application increased tobacco yield but not sufficiently. The stimulant effect of Azotobacter chroococcum, including various mechanisms such as the production of siderophore and nitrogen, stimulates plant growth and increases yield (45).…”

The present study was performed to evaluate the effect of mycorrhizal symbiosis and azotobacter with the application of biochar on tobacco growth parameters, yield and nicotine content under rainfed conditions for two growing seasons (2016-2017 and 2017-2018). The factorial experiment was performed based on a randomized complete block design with four replications and three factors including biochar at three levels (0, 4 and 8 ton/ha), mycorrhizal fungi and Azotobacter chroococcum each one at two levels (without and with application). Results showed that biochar application had a significant and positive effect on all evaluated parameters. However, there was no statistically significant difference between 4 and 8 tons per hectare of biochar in yield. Mycorrhizal symbiosis had a significant effect on relative water content. Application of azotobacter had a positive and significant effect on growth parameters, yield and nicotine content under rainfed conditions for two growing seasons (2016-2017 and nicotine content. The greatest effect of azotobacter with a 17% increase was on leaf nicotine content. Whereas tobacco dry yield in rainfed conditions is lower, the combined use of biochar and these biofertilizers can be considered a desirable solution. Then in terms of economic aspects, the use of 4 tons biochar per hectare along with the use of mycorrhiza and azotobacter to achieve acceptable yield while maintaining chemical quality in tobacco farms is recommended.
