|
This study was conducted to investigate plug seedling quality and early growth after transplanting of red pepper. Seedlings were grown for 30, 45 or 60 days in 128, 162, 200 or 288 plug cell sizes, as compared to the control which were 80 days in 9 ㎝ black plastic pots. Seedling growth increased with seedling age and plug cell size. Sixty days old seedlings with height greater than 30 ㎝ regardless of cell size presented a problem of shoot-top cut off when transplanted with KTP-3 transplanter. Forty five days old seedlings raised in 128 plug cells, with a mean height of 28.3 ㎝, were optimal for mechanical transplanting, when considering growth and early yield after transplanting. The first harvesting date delayed by 19∼22 days in 30 or 45 days old seedlings as compared to the control. Therefore, control of the seedling height smaller than 30 ㎝ and extention of seedling age to 60 days are necessary for rapid transplant recovery and fruit yield after transplanting.
