Abstract

Considering the benefits of intensive agriculture in our time and the negative impact of chemical fertilizers and pesticides against the environment, usage of PGPR (plant growthpromoting rhizobacteria) like biofertilizers is one of the most promising biotechnology used for growing the primary production with less quantity of chemical fertilizers. The usage of PGPR may be an alternative to organic fertilizers and can reduce the pollution and preserve the environment in the spirit of practicing an ecological agriculture. In this context it was analyzed the influence of some rhizospheric bacteria in maize development and the impact on the productivity in conditions of unapplying organic fertilizers. Accordingly of using PGPR, the foils number mean value was greater at the probe in regard to the control. The inoculated bacteria strains determine modification of assimilation pigments content, with positive influences on the respiration processes (photosynthesis) and implicitly on growth of maize plant development. Without organic fertilizers, usage the PGPR may cause a productivity increase/ha by 16.28 \%.
