Abstract
Worldwide growth in population, increase in demand of global food production and environmental damage causing problems in agriculture yield are major concerns. These problems may soon cause insufficiency to feed all of the world population. Adding up in to the above mentioned constrains, there is loss in the agricultural production due to environmental abiotic and biotic stresses posed on the crops growing in the field. Abiotic stresses such as drought, salt stress and temperature stress are major limiting factors in crop production. On the other hand, biotic stresses also cause reduction in agricultural yield due to diseases in field crops. These diseases decrease the annual agriculture yield by at least 30% globally. So, any effective and longer term solutions to provide food for the world must include sustainable and eco-friendly biological solutions. In context to this problem, use of plant growth promoting rhizobacteria (PGPR) in agriculture is a striking technology hypothesized to overcome these constrains.
