An vitro test revealed that strain could fix nitrogen, solubilize phosphate potassium, synthesize indole acetic acid. The bacterial identified characterized as a kind Pseudarthrobacter chlorophenolicus based on analysis culture characteristics, physiological biochemical 16S rRNA gene sequence (GenBank accession number OP135548.1). pH 7.0, 15% NaCl, 35 °C temperature were ideal for optimal under conditions. Tomato plants grown cocopeat substrate inoculated with suspension (OD600 2.0). Positive control Nitrogen Phosphorus Potassium (NPK) fertilizer. This NPK treatments complemented negative control, which only tap water applied roots, thus, establishing three distinct treatment modalities five replications each. Two months greenhouse trials improved parameters.

Abiotic stresses are the most significant factors reducing agricultural productivity. Plants face extreme environmental conditions that may affect their biological mechanisms, thereby influencing growth and development. Microorganisms possess substantial metabolites aid in helping plants mitigate abiotic stresses. Plants’ interaction with microbes constitutes a diversified ecosystem, as sometimes both partners share mutualistic relationship. Endophytes, plant-growth-promoting rhizobacteria (PGPRs), arbuscular mycorrhizal fungi (AMFs) examples of microorganisms play an essential role alleviating and, hence, improving plant growth. The plant–microbe leads to modulation complex mechanisms cellular system. Moreover, residing microbial flora also inhibits phytopathogens, therefore, it becomes part plants’ innate defense Keeping view growing concerns, is important identify microbiome transportation nutrients maintain sustainable production. Furthermore, enabling recruit beneficial species how deal potential pathogens. Therefore, this review aims summarize impacts various stressors on productivity mitigating negative effects literature shows microbes, including PGPRs, AMFs, endophytes, adopt for ameliorating It has been observed biochar either individually or combination, can maintaining under stress conditions. Although conventional inoculation mitigates enhances productivity, advancement genetic engineering would help transfer specific genes from mitigation.

Biopriming usually refers use beneficial microorganisms, particular plant growth-promoting bacteria (PGPB) able survive under various harsh environmental conditions. this study, bacterial strains were isolated from samples different origins, i.e., rhizospheric soil, desert sand, sea mud. Preliminary screening 156 isolates was conducted on basis their potassium (K), phosphorus (P) solubilization ability, production growth hormone, indole acetic acid (IAA). The most efficient identified by 16S rRNA gene nucleotide sequences further examined for ACC deaminase activity, ammonia production, biocontrol activity (defined via chitinolytic HCN, siderophores production). Finally, carrot germination assay with 10 shortlisted potent isolates. 68.6, 58.3, 66.7% tested capable P, K, Zn solubilization, respectively. Klebsiella aerogenes AF3II1 showed highest P K while isolate AF4II5, AF7II3, PC3 IAA synthesis ability.

Increasing food demand by the ever-growing population imposes an extra burden on agricultural and industries. Chemical-based pesticides, fungicides, fertilizers, high-breeding crop varieties are typically employed to enhance productivity. Overexploitation of chemicals their persistence in environment, however, has detrimental effects soil, water, air which consequently disturb chain ecosystem. The lower aqueous solubility higher hydrophobicity agrochemicals, metals, hydrocarbons allow them adhere soil particles and, therefore, continue environment.
