Principal component analysis (PCA) biplot illustrating the multivariate response of olive trees to 16 foliar treatments consisting of CHNPs (0, 500, 1000, and 1500 ppm), N-ATCA (0, 50, 100, and 150 ppm), and their combinations. The measured 11 parameters included shoot number, number of leaves, leaf N%, P%, and K%, yield, oil percentage, firmness, hue angle, saturation value and brightness value. PC1 and PC2 explained 82.5% and 9.4% of the total variance in 2021 and 79.2% and 9.7% in 2022, respectively.
