Abstract
In this study, the effects of zinc and iron treatments in different growth stages on yield and yield components of soybean (Glycine max L.) plants were evaluated by principal component analysis (PCA). Field experiments were conducted over during the second crop seasons of the years 2018 and 2019. The experiment was designed as a split-split plot design with three replications. Three varieties of Arisoy, Bravo, and Nazlican were placed in main plots, growth stages of the soybean (V3, R1, R3) in subplots and foliar fertilizers (Zn, Fe, Zn+Fe) in sub-sub plots. Variance analysis revealed that all parameters were significant except the first pod length (2019) and 1000-seed weight (2019). PC1, PC2, and PC3 explained 84.50% of the total variation in 2018 and 86.10% in 2019. Zn + Fe mixture treatment could be recommended for foliar spray because the highest seed yields were obtained from Zn + Fe in both years.
