The aim was to explore the application effect of different nano-sized fertilizers (zinc, iron and manganese) and sulfur fertilizer on chickpea. The sulfur fertilizer had three levels (S1 : no application, S2 : 15 Kg ha-1, S3 : 30 Kg ha-1) and the nano-fertilizer was including nano-chelated zinc (Nano1), nano-chelated iron (Nano2), and nano-chelated manganese (Nano3). According to results the first two principal components (PC1 and PC2) were used to create a two-dimensional treatment by trait (TT) biplot that accounted percentages of 61% and 19% respectively of sums of squares of the TT interaction. The vertex treatments in polygon of TT biplot were S3-Nano1, S3-Nano3, S1-Nano1, S1-Nano2, and S1-Nano3 which S3-Nano1 treatment indicated high performance in days to 50% flowering, plant height, primary branch per plants, secondary branch per plant, first pod height, 1000 seed weight and seed yield. The identification of ideal treatment, the treatment that is most favorable treatment among all ones, showed that the S3-Nano1 (30 kg ha-1 sulfur plus nano-chelated zinc) might be used in selecting superior traits and it can be considered as the candidate treatment. Treatments suitable for obtaining of high seed yield were identified in the vector-view function of TT biplot and displayed S3-Nano1 (30 kg ha-1 sulfur plus nano-chelated zinc) as the best treatment suitable for obtaining of high seed yield.
