The growth of citrus seedlings has not only been influenced by fertilizer management but also species and cultivar as well. The purpose of this study was to evaluate the growth performance of Siam and Keprok seedling to inorganic fertilizer treatment under nursery house. Research was conducted in Nursery House, ICISFRI, Batu, East Java, Indonesia from February to November 2020. Factorial Randomized Block Design was used in this research consisted of two factors, I: Doses (0 %; 50 %: 2.5 g NPK + 2.5 g ZA/plant), and II: Cultivars (Tangerine/Siam cv. Banjar, Madu, and Pontianak; Mandarin/Keprok cv. Gayo, Kacang, and Madura) with three replications. An orthogonal contrast analysis was also used to identify the response of Tangerine and Mandarin group. Among 16 variables, only plant height, leaf thickness, and shoot dry weight were significantly influenced by the interaction between doses and cultivars with value of p<0.01; R 2 = 98.08 %; p<0.05; R 2 = 85.77 %; and p<0.01; R 2 = 99.14 %, respectively. Eight of 16 morphological and physiological traits (50 %) applied with either 0 % or 50 % gave similar responses between Mandarin and Tangerine group. Application of 50 % and 0 % produced 68.80 % and 81.30 % of similarities between Tangerine cv. Pontianak and Banjar, respectively. Meanwhile, similarities of Tangerine (Pontianak and Banjar) versus Tangerine cv. Madu that was applied with 0 % and 50 % of fertilizer application were 68.75 and 93.75 %, respectively.
