AbstractA field experiment was carryout in the city of Ramadi during 2016-2016 and with full design RCBD For the purpose of knowing the effect vaccination with bacteria Rhizobium and Pseudomonas (Isolated from agricultural soil). In reducing the amount of chemical fertilizers added according to the recommendation of the Ministry of Agriculture, and the results showed the superiority of the treatment of bacteria Rg (Isolation of isolated rhizobium from the leaves plant) with F2 fertilization level (half of the fertilizer recommendation). In the form of plant height on the rest of the transactions and an increase of 33.4% for the comparison treatment, and the treatment of Rg with the level of F2 fertilizer fertilizer and amounted to 82.33 node-1 in the number of root nodes formed at the roots of the plant the Rg treatment with F2 fertilization achieved the highest weight of the root contract of the plant when compared with the control treatment of 239.6 mg-1 The total yield was 109.4% for the treatment of Rg with the F2 fertilization level of the comparison treatment, while the concentration of N and P in the vegetative group of 2.75% and 0.28% for the treatment of Rg and Ps were isolated at the F2 fertilization level respectively. The concentration of N and P in the soil was 58 mg / kg -1 soil and 7.86 mg / kg -1 soil for treatment Rg and Ps at the F2 fertilization level on the relay.
