The objective of this study was to evaluate the growth and quality of 5 baby vegetables [i.e., Compositae (romaine red, lollo rosa, endive) and Cruciferae (pak-choi and ssamchoo)] grown under 50, 72, 128, and 162 cell-plug tray, and determine proper cell size of plug tray for the practical cultivation of the baby vegetables. The baby vegetables were grown with 1.0 time of Yamazaki nutrient solution and harvested on 23 days after sowing. The baby vegetables of Compositae and Cruciferae showed different growths and qualities depending on the cell size of plug tray. Compositae baby vegetables (i.e., romaine red, lollo rosa, and endive) showed the higher yield per plug tray, visual quality, and edible ratio grown in 162 cell-plug tray than others. Vitamin C content was not affected by cell size, but nitrate content increased as cell size decreased. However, Cruciferae baby vegetables (i.e., pak-choi and ssamchoo) had high top fresh weight, high vitamin C contents and low nitrate in 72 cell-plug tray. In conclusion, 162 cell-plug tray for Compositae baby vegetables and 72 cell-plug tray for Cruciferae baby vegetables were determined to increase the production of baby vegetables with high quality.
