Bacterial Plant Biostimulants: A Sustainable Way towards Improving Growth, Productivity, and Health of Crops

This review presents a comprehensive and systematic study of the field bacterial plant biostimulants considers fundamental innovative principles underlying this technology. Plant are an important tool for modern agriculture as part integrated crop management (ICM) system, helping make more sustainable resilient. contain substance(s) and/or microorganisms whose function when applied to plants or rhizosphere is stimulate natural processes enhance nutrient uptake, use efficiency, tolerance abiotic stress, biocontrol, quality. The has gained substantial significant heed worldwide environmentally friendly alternative agricultural production. At present, there increasing curiosity in industry researchers about microbial biostimulants, especially (BPBs), improve growth productivity. BPBs that based on PGPR (plant growth-promoting rhizobacteria) play plausible roles promote/stimulate through several mechanisms include (i) acquisition by nitrogen (N2) fixation solubilization insoluble minerals (P, K, Zn), organic acids siderophores; (ii) antimicrobial metabolites various lytic enzymes; (iii) action regulators stress-responsive/induced phytohormones; (iv) ameliorating stress such drought, high soil salinity, extreme temperatures, oxidative heavy metals using different modes action; (v) defense induction modes. Presented here brief emphasizing applicability exertion fulfill current food crisis.
