Figure 4

Loading plot presentation of the Principal Component Analysis (PCA) results showing the brinjal fruit (blue lines) and soil (dashed red lines) parameters. In the figure, the length of each eigenvector is proportional to the variance in the data for that variable. The angle between the eigenvectors represents the correlations among the different variables. The colored circle groups of variables indicated by I, II, III and IV show strong positive correlations with each other.
