Azotobacter : A Plant Growth - Promoting Rhizobacteria Used as Biofertilizer
Nitrogen fixation is mainly responsible for improvement of crop yield. In this regard, diazotrophs like Rhizobium, Azotobacter and Azospirillum are important as they enrich nitrogen nutrition in N-deficient soils. Of these, Azotobacter promotes plant growth as well as nitrogen fixation. Thus technology has been developed for making use of Azotobacter biofertilizer for nitrogen and non-nitrogen ...
متن کاملPlant growth-promoting bacteria as inoculants in agricultural soils.
Plant-microbe interactions in the rhizosphere are the determinants of plant health, productivity and soil fertility. Plant growth-promoting bacteria (PGPB) are bacteria that can enhance plant growth and protect plants from disease and abiotic stresses through a wide variety of mechanisms; those that establish close associations with plants, such as the endophytes, could be more successful in pl...
متن کاملPlant Growth-Promoting Bacteria: Mechanisms and Applications
The worldwide increases in both environmental damage and human population pressure have the unfortunate consequence that global food production may soon become insufficient to feed all of the world's people. It is therefore essential that agricultural productivity be significantly increased within the next few decades. To this end, agricultural practice is moving toward a more sustainable and e...
متن کاملDiversity of plant growth-promoting bacteria associated with sugarcane.
The sugarcane (Saccharum spp) presents economic importance, mainly for tropical regions, being an important Brazilian commodity. However, this crop is strongly dependent on fertilizers, mainly nitrogen (N). This study assessed the plant growth-promoting bacteria (PGPB) associated with sugarcane that could be used as a potential inoculant to the crop. We evaluated the genetic diversity of PGPB i...
متن کاملClément 4 Environmental uses of plant growth - promoting bacteria
Plant growth-promoting bacteria (PGPB) are commonly used to improve crop yields. In addition to their agricultural usefulness, there are potential benefits in environmental applications. For example, species of Azospirillum can increase bioremediation of wastewater by microalgae by increasing algal proliferation and metabolism. Additionally, these genera and several other bacterial species may ...
