Abstract: 
Studies shown use of chemical fertilizers such as N fertilizer cause to increase plant growth plant, but have ecological dangerous effects. Therefor use of plant growth promoting rhizobacteria that prouduce high auxin can be effective for morphological characteristics improvment, increase growth and environment preservation. In this research, rice seedling of Neda variety inoculated with 5 isolates Psuedomonas (PF1, PF2, PP1, PP2 and PP3) with producing auxin ability and 1 treatment as control in 4 replication. Seeds sown in pots that their soil properties were measured by standard method. Three plants stay per pot after tillering.Leaves N, K content, length and fresh weight of root measured in flowering. Morphological characteristics such as plant height, total fresh weight, and yield and nutrient elements of seeds measured after physiological maturity. Results showed in following seedlings inoculation, root length, root fresh weight, plant height, total fresh weight, leaves and seeds N content and yield increased, significantly. Generaly, these bacteria directly stimulate plant growth through nutritional and physiology mechanisms.
