To increase the yield of one-year-old asparagus stocks grown in open field culture, a longer period for stock cultivation is required. The purpose of this study is to clarify the shape of holes appropriate for the early planting of asparagus. In the present study, plug seedlings were planted in five holes of different shapes, and the temperatures of the holes and growth were compared. The chilling hours less than 5℃ were the most in the funnel-form holes II, followed by the conventional hole, the funnel-form holes I, the reverse bottle holes and cylindrical hole. The growth of seedlings planted in the reverse bottle holes was higher than that of seedlings planted in other holes. Therefore, the shape of the reverse bottle holes is the most appropriate for the early planting of asparagus.
