Chapter 9 - Involvement of soil parameters and rhizosphere microbiome in sustainable crop productivity

Abstract

Sustainable development goals by the United Nations promote global crop productivity and crop quality maintenance to minimize the food crisis. Crop cultivation might vary region-wise although rhizospheric soil microbiome similarly plays a critical and inductive role in crop productivity globally. Plant growth-promoting rhizobacteria and arbuscular mycorrhiza (AM) are some of the best crop quality inducers followed by macro/microalgae and other fungi. Crop plants are known to regulate various secondary metabolites, root exudates and mineralogical conversions where these microbes are involved inevitably. Rhizospheric microbes can certainly control other pathogenic microbial colonization and crop pathogen manifestations. These combined effects exert a positive impact on the associated crop health and productivity. Soil physiochemical parameters, abiotic stresses and nutrient deficiencies are well-managed within the rhizospheric microbiome. Crop growth-promoting microbes are also known to trigger plant tolerance mechanisms allowing better crop health. Plant microbial symbiosis can elucidate this insight using a nodular and nonnodular crop plant. So, a better crop yield and quality maintenance should involve a rhizospheric microbiome dealing with multiple sustainable applications.
