The principal components analysis (PCA) showed the strongest relation between the length of the aboveground parts of the plants and their weight. There was a similar relation between the weight of the aboveground parts of the plants and the weight of their belowground parts. There were no such relations between the length of the belowground parts of the plants and the other parameters under analysis. The strongest influence on the plant parameters under analysis was observed in the coinoculation variants (variants seven, eight, and nine). Most of the parameters, i.e., the length and weight of the aboveground parts of the plants as well as the weight of their belowground parts, were the most strongly influenced by the coinoculation of white lupine seeds with bacteria of the _Bradyrhizobium_ genus isolated from the Nitrolora preparation and the _Bacillus subtilis_ endophyte (variant nine) (Figure 2). There were no relationships between the biometric parameters observed in the control variant, where no seed inoculation had been applied. \begin{table}
