The experiment was laid out in split - plot design SPD with four levels of nitrogen 3 4 5 Keywords 6 g pot being the main factor and three lisianthus cultivars Pink Yellow White Purple being the subordinate factor. Each pot was Cultivars planted with one plantlet. The results indicated that plants applied Eustoma grandiflorum Raf. Shinn with g nitrogen per pot gave the best performance in plant height cm and number of leaves leaves plant at 60 Lisianthus days after planted DAP . The Pink cultivar reached the highest Nitrogen plant height cm number of leaves leaves plant Pot-planted as well as number of flowers buds buds plant . The Pink cultivar when applied with g nitrogen pot gave the highest Corresponding author plant height cm at 60 DAP. Pham Thi Thuy Duong Email pttduong@ Cited as Pham D. T. T. Pham D. H. A. Nguyen H.
