In order to investigate the effect of inoculation with Rhizobium legominosarum and Pseudomonas fluorescens on leaf area index, dry matter accumulation and allocation of Vicia faba L. an experiment have been conducted as a split-plot in an RCBD with four replications at the farm of Agricultural Research Station of Golestan Province during the cropping seasons of 2015-2016 and 2016-2017. As the main-factor, Rhizobium was considered in two levels of with and without inoculation, while the sub-factor included Pseudomonas in density levels of 0, 9×103, 9×105, 9×107, and 9×109 alive bacteria per ml of inoculants. A logistic model was used to analyze the changes in the leaf area index and dry matter accumulation. A combined ANOVA for the two years of the study indicated that the climatic conditions influenced the bacteria effects. In the second year, the traits indicated a significant reduction in comparison with the first year. Results of the first year showed a positive effect of the inoculation of Rhizobium on maximum dry weight (8%) in comparison with the control and co-inoculation with Pseudomonas (9×105 bacteria per ml) led to the greatest dry matter distribution coefficient for stems in the podding stage. In the second year, Pseudomonas (9×105) increased the maximum dry weight (23%) in comparison with the control. Also, the density increase of Pseudomonas under co-inoculation with Rhizobium led to a significant reduction of the day to maximum LAI. In conclusion, co-inoculation Rhizobium whit Pseudomonas can have a positive effect on the growth indices of faba bean.
