An experiment was carried out to investigate the effect of the vinyl pot size and number of plants per pot on the seedling growth. Dry weight per plant, coefficient of variance and dry weight/fresh weight ratio increased as pot size increased, but competitive index, unit productivity and top/root ratio decreased. Dry , weight per plant decreased with increase in number of plants per pot, but coefficient of variability, competitive index and unit productivity increased. Dry weight per plant of the check plot (1 seedling/3.5cm $\times$ 3.5cm pot) showed little difference between 3 plants/4cm x 4cm pot and 5 plants/5cm x 5cm pot. Temporary transplanting of five plants per 5cm $\times$ 5cm pot saved seedbed area and seedbed materials by 60.9% and labor of transplanting by 36.3% as compared with check plot.
