Plant Growth Promoting Rhizobacteria (PGPR) are a group
of bacteria that enhances plant growth and yield via various
plant growth promoting substances as well as biofertilizers.
Given the negative environmental impact of artificial fertilizers
and their increasing costs, the use of beneficial soil microorganisms
such as PGPR for sustainable and safe agriculture
has increased globally during the last couple of decades.
PGPR as biofertilizers are well recognized as efficient soil
microbes for sustainable agriculture and hold great promise
in the improvement of agriculture yields.
