This study was carried out to investigate the effects of forms and levels of nitrogen fertilizer on plant growth and essential oil content in Agastache rugosa. Calcium nitrate had more influence on leaf length and width, and lateral branch length than urea. When nitrogen fertilizer level was increased from 120 kg N/ha to 240 kg N/ha, plant growth was stimulated and dry matter of leaf and inflorescence were increased. Top dry matter of plant with calcium nitrate treatment was heavier than that of urea treatment. Interactions among accessions and nitrogen form and nitrogen rate were not significant for top dry matter. The forms and rate of nitrogen fertilizer did not affect major essential oil, estragole content. The estragole content was higher in leaf (91.8%) than that of inflorescence (81.3%)
