The experiments were performed to clarify the effect of fertilization level, planting rate and planting depth on the growth of Pinellia ternata. The results obtained were as follows: 1. P. ternata has rather the adaptability for heavy manuring; 7kg N, P and K/are increased significantly the weight of corms, the number of bulblets and aerial tubers. And it was recognized to be a nitrogen-favored plant from the fertilizer reqirement experiments. 2. The weight of corms and the number of aerial tubers were progressively greater in the plot of 5 corms per pot (1/2,000 are) than 20 or 30 corms. 3. The corms sprouted 60〜50% even in the 20cm depth and positive and significant relations between the growth of corms and planting depth were obtained. The shallow planting less than 5cm depth, increases the weight of corms and the number of aerial tubers.
