파 플러그 육묘 시 품종에 따른 육묘 용기와 일수가 생육과 수량에 미치는 영향

The aim of this study was to determine the effect of seedling age (40, 65 or 90 days) and plug tray cell size (406, 200 or 128 cells per tray) on the growth and marketable yield of two spring onion types, ‘Baegam oedae’ and ‘Seoldong hanlo’. Our results shows that the seedling age and plug tray size affected the amount of growth that both cultivars experienced before transplantation. The fresh weight and diameter of the stem of the 90-day-old seedling grown in 128- or 200-cell trays were higher than that of the others. However, the 65-day-old seedling produced a significantly greater yield than those of 40- or 90-day-old seedlings after transplanting. The yield of seedlings grown in 128- and 200-cell trays was higher than 488 cells. The results seem to suggest that 65 days of onion growth using 128-/200-cell trays is the most advantageous growth scheme for green onion seedlings. This growth scheme would result in the highest likelihood of producing a strong marketable yield.
