Survey of the Influences of Microbial Biostimulants on Horticultural Crops: Case Studies and Successful Paradigms

Sustainable farming of horticultural plants has been the focus research during last decade, paying significant attention to alarming weather extremities and climate change, as well pressure biotic stressors on crops. Microbial biostimulants, including plant growth-promoting bacteria (PGPB) arbuscular mycorrhizal fungi (AMF), have proven increase growth via both direct indirect processes, availability uptake nutrients, boosting soil quality, increasing plants’ tolerance abiotic stress overall quality attributes various crops (e.g., vegetables, fruit, herbs). The positive effects microbial biostimulants confirmed so far, mostly through symbiotic interactions in plant–soil–microbes ecosystem, which are considered a biological tool parameters decrease degradation. However, more is needed address future challenges crop production revealing mechanisms action identifying response patterns products. present review aims most up-to-date results regarding practical applications species, case studies successful paradigms for important genera PGPB AMF. Moreover, actions briefly described while remarks also discussed, aiming suggest further needs be addressed establishment sustainable production.
