This study was conducted to improve year round production of onion sets for pickles and increase their yield by using different cell sizes of plug trays. 'Josaeng sseondeobol' and 'Daeji' were seeded in 105-cell tray, 128-cell tray, and 162-cell tray on March 27, 2010. 'Josaeng sseondeobol' showed the maximum number of leaves on May 23, but 'Daeji' showed the maximum in late June. Bulbing of 'Josaeng sseondeobol' was already initiated on May 23, but 'Daeji' was initiated on June 6. Growth of both varieties was better in 105-cell tray than the others. There wasn't a difference in bulbing between two varieties by the number of cells, but bulb size was larger in the low number of cells than high ones. 'Josaeng sseondeobol' was all harvested in July, but more than 50% of 'Daeji' was harvested in August. The result of this study is as follows. Harvest time was delayed as the number of cells is increasing. There was a wide range of small onion sets distribution in both varieties as the number of cells is increasing.
