Importance of PGPR in organic farming A Short Review
Main Article Content
Abstract
Farmers' growing reliance on chemical fertilizers has enhanced agronomic
output, but it has also increased environmental contamination and put the
stability of the world's ecosystem in greater danger. By making abiotic
stresses more frequent, climate change has exacerbated the issue. Even if
agriculture is only permitted on 50% of the world's livable land, it is critically
necessary to ensure its sustainability and security. Boost crop yield and food
security while using little to no chemical fertilizers and pesticides is one of
contemporary agriculture's greatest problems. The vanguard of
environmentally friendly farming methods is rhizobacteria that promote plant
development (PGPR). They offer an advantageous and safe alternative to
chemical fertilizers as well as a suitable solution to less difficult situations.
Numerous bacterial species that function as PGPRs have significantly
enhanced plant growth, well-being, and production. The major subjects of
this review include the use of these rhizobacteria under various stress
circumstances, their significance in sustainable agriculture, and the
underlying mechanisms driving growth promotion
