Plausible Role of Microbiome as Biofertilizers, Biopesticides or Biostimulants for Improving the Crop Health

Many bacterial strains in the rhizosphere have processes that aid in the growth of plants. Crop yields can be increased by using these bacteria as biofertilizers not only in forestry but also in agriculture. Bacterial biofertilizers can boost plant development in many ways. Plant biostimulants are significant in integrated crop management (ICM) systems because they promote different beneficial activities in plants and their surroundings. They are intended to improve crop output, quality, and sustainability by utilizing plants' natural capabilities. Plant biostimulants have gained significant attention as an eco-friendly alternative for promoting sustainable agricultural practices. These products are used to enhance plant growth, improve crop productivity, and increase resistance to various environmental stresses. Among the different types of biostimulants, microbial biostimulants, including bacterial plant biostimulants (BPBs), have attracted particular interest from both the industry and researchers. The plant growth-promoting rhizobacteria (PGPR) that the BPBs are based on play plausible roles in promoting/stimulating agricultural plant growth in a variety of ways. The increasing use of pesticides and synthetic fertilizers is damaging to biodiversity of soil microbes and environmental pollution. The practice of using microorganisms as biofertilizers has been suggested as an alternate agricultural technique in response to this growing problem. Although a lot of research has been done on bacteria, in recent years, there has been more focus on the little that is known about yeasts and their potential to safely stimulate plant development.
