Research directed towards the
development of approaches for sustainable growth
is the need of the hour. A key point of focus should
be the beneficial interactions between plants and
microbes in order to facilitate sustainable
agricultural practices. Biotechnology has opened
new avenues for the application of beneficial soilbacteria
for the promotion of plant growth and
the biological control of phytopathogens. Plant
growth promoting rhizobacteria (PGPR) are
plant-friendly bacteria that reside in the root-zone
of plants and affect it in many direct and indirect
ways. PGPR have attracted the attention of
scientists throughout the world for their role in
improving plant growth and health and the results
to date are very promising. Use of PGPR as soilinoculants
for many crops has shown significant
improvement in their growth and yield through
increased seedling germination, plant vigor, shoot
height and weight, chlorophyll content and
increased nodulation in legumes. They employ a
variety of mechanisms to affect the overall health
and growth of plant. The use of PGPR is steadily
increasing in agriculture and offers an attractive
way to replace chemical fertilizers, pesticides, and
supplements
