    Increasing soil fertility is one of the strategies being implemented with the objective of increasing agricultural production. The addition of microbial inoculants can stimulate plant-growth-promoting mechanisms, improve soil fertility, replenish the natural microbial community. There are different mechanisms by which microorganisms increase soil fertility and supply plants with necessary elements. The experiment was a two-factorial, random block design with ten replicates, where the first factor was alfalfa cultivar and the second was the variant of bacterial inoculation. For the purposes of research three alfalfa cultivars (K−28, Affinity+Z and Perry) and two variants of microbial inoculation − individual cultures of rhizobium (Sinorhizobium meliloti) and azotobacter (Azotobacter chroococcum) were used. The analysis of plant traits (height, number of stems and plant weight) were done at the beginning of flowering. The results obtained showed that the application of microorganisms can affect the parameters of plant alfalfa. The interaction between cultivar and applied inoculation was different: In the cultivar alfalfa Affinity+Z a statistically significant increase in plant height (4.4{\%} higher value than control) and mass was recorded (16.1{\%}); in Perry cultivar the green mass per plant was increased (4.3{\%} on treatment with S. meliloti and 2.3{\%} on treatment with A. chroococcum). In all cultivars inoculation A. chroococcum had positive, but application of S. meliloti had negative effect on the number of stems was achieved.
