Table 3: Mean values, standard deviations (s.d. ), [PERSON]’s least significant differences (LSD) and homogeneous groups of the macronutrient content (g-kg\({}^{-1}\) DM) of _Poa pratensis_. Figure 2: _Cont_. Figure 2: Cont. The greatest variation in terms of all the traits, based on the measured Mahalanobis distances, for cut I was found for control and amino acids + Ti (the Mahalanobis distance between them amounted to 6.740). The greatest similarity for cut I was found for amino acids and Ti (2.489) (Table 4, Figure 2). For cut II, the Mahalanobis distances ranged from 1.179 (between Ti and control) to 2.988 (between control and amino acids + Ti) (Table 4, Figure 2). In cut III the greatest similarity (1.944) was observed between the effects of amino acids and amino acids + Ti, but the largest distance (8.594) between control and amino acids + Ti (Table 4, Figure 2). For all three cuts jointly the Mahalanobis distance ranged from 2.175 (between amino acids and amino acids + Ti) to 11.491 (between control and amino acids + Ti).
