The experiment was carried out to study the influence of planting densities and fertilizer application levels on some agronomic characters and yield of flower-head in Zingiber mioga ROSC. The results obtained are summarized as follows ; Plant hight was long in dense planting, and short in spacious planting. Stem diameter was thick in spacious planting, and was thin in dense planting. Flower-head weight per plant was decreased in dense planting and was increased in spacious planting. Yield was higher in dense planting densities (10$ imes$20 : 50plants /m$^2$, 20$ imes$20 : 25plant /m$^2$). Fertilizing (N : P$_2$O$_{5}$ : $K_2$O=15 : 15 : 15kg /10a) was increased than without fertilizing because plant height and number of stem was good.d.
