Growing environmental concerns are potentially narrowing global yield capacity of agricultural systems. Climate change is the most significant problem world currently facing. To meet food demand, production must be doubled by 2050; over exploitation arable lands using unsustainable techniques might resolve demand issues, but they have negative effects. Current crop systems a major reason for changing climate through diminishing biodiversity, physical and chemical soil degradation, water pollution. The application fertilizers pesticides contribute to greenhouse gas emissions (GHG) toxic depositions.

Rhizospheric organisms have a unique manner of existence since many factors can influence the shape microbiome. As we all know, harnessing interaction between soil microbes and plants is critical for sustainable agriculture ecosystems. We achieve agricultural practice by incorporating plant-microbiome as positive technology. The contribution this has piqued interest experts, who plan to do more research using beneficial microorganism in order accomplish vision. Plants engage wide range interrelationship with microorganism, spanning entire spectrum ecological potential which be mutualistic, commensal, neutral, exploitative, or competitive. Mutualistic found plant-associated microbial communities assist their host number ways. Many studies demonstrated that microbiome may provide significant advantages plant. However, various conditions (pH, temperature, oxygen, physics-chemistry moisture), environments (drought, submergence, metal toxicity salinity), plant types/genotype, practices result distinct composition characteristics, well its mechanism promote development defence against these stressors.
