The experiment was carried out to study the influence of seeding dates, planting densities and fertilizer application levels on some agronmic characters and yield of fresh weight in Agastache rugosa. The results obtained are summarized as follow; Fresh weight was increased on Apr. 1 seeding date. Therefore, optimum time for sowing was on Apr. 1. Stem length was long in dense planting and short in spacious planting. Stem diameter was thick in spacious planting, and was thin in dense planting. Yield was higher in dense planting densities(10×20cm:50 plants/m2, 20×20cm:25 plants/m2, (30×20cm:17 plants/m2) Fertilizing (N:P2O5;K2O=6:6:6kg/10a) was increased than without fertilizing because stem length and number of leaf were good.
