Seed priming with microbial inoculants for enhanced crop yield

Advanced technologies are used in modern agriculture, aimed at maximizing crop yield and increasing agricultural output. Modern agriculture is facing new challenges in meeting rising food demands, remaining internationally competitive, and producing high-quality agricultural products. Seed priming is a physiological and presowing method in which seeds are moderately moistened to the point where pregermination metabolic pathways are activated, allowing for quick germination, growth of seedlings, and eventual yield under natural and stressed conditions. Biopriming is the use of a living microorganism’s inoculum to apply plant growth-promoting microorganisms (PGPMs) to seeds. Over the last few decades, inoculation of PGPMs has proven to be a successful and environmentally acceptable approach to increasing the durability of food supply while limiting its ecological impact. This chapter highlights the methods of biopriming based on the superior solutions of PGPM inoculants as an alternative to chemical treatments in current agriculture, which are more eco-friendly for future farming.
