Score plots (a, b) showing the result of a PCA on the elemental (Ca, K, Mg, Mn, Na, P) composition of the grain, stem and leaves. Samples are grouped either according to the P fertiliser applied (a) or BE inoculation (b). In a filled circles represent samples from the Humpolec soil, while open triangles represent samples from the Poděbrady soil. Loading plot (c) showing the loadings of the first principal component. Loading plot (d) showing the loadings of the second principal component. Data are from the CULS experiment
