A number of biological, healthy and economic problems concerning the consumption of chemical fertilizers caused the use of biological Nitrogen fixing (BNF) process has been taking into account by some researchers.Therefore they are interested to the use of biological Nitrogen fixing process that are taking place by some life (precariots) which lived in plant root rhizosphere.These can obtain Nitrogen for plant and moreover, they have the ability to produce some kinds of Growth Hormones, Vitamins, Antibiotics and Amino-Acids. So they are called Plant Growth Promoting Rhizobacteria or PGPR. Some studies and researches have been conducted in this area in order to produce biofertilizers for paddy soils in Rice Research Institute of Iran and Agricultural Biotechnology Research Institute since 1375. These studies led to access four useful and appropriate strains in order to produce biofertilizers. This research project is carried out under field conditions in 1381 in order to evaluate the biofertilizers’ efficiency produced from PGPR resources.The findings have shown that the local strains which isolated from Iran paddy soils have more efficiency than some foreign standard species of PGPR.
