Potato (Solanum tuberosum L.), is one of the important crops grown in the world which is important as food and nutritional security option at the global level. The experiment was laid out as randomized complete block design in three replications with six nutrition treatments consisted of control, NPK, Mog bio-fertilizer, Nano-Ca, Nano-Zn+B and Nano-Com. The treatment-by-trait (TT) biplot analysis was applied to data to examine its usefulness in visualizing relationships among trait as well as treatments and showed that the first two principal components accounted 80% of total variation. Tuber yield, mean tuber diameter, mean tuber weight, tuber weight per plant, starch content of initial fresh, number of tubers per plant, number of leaves and dry matter content were in the same sector, with Nano-Com fertilizer treatment as the best treatment. Based on ideal entry biplot, the Nano-Com treatment is closest to the position of an ideal treatment and it is ranked the highest in term of morphological performance. Also, the best fertilizer treatment for obtaining of high tuber yield could be found as Nano-Com treatment following Nano-Zn+B treatment. The studied nanofertilizers showed a good potential compared to the commercial bulk and bio fertilizers.
