Abstract: This study aimed to investigate the suitable of layer on growth of six baby leaf vegetables using existing facilities and equipment in rice seedling nursery.Three kinds of Lactuca(lettuce 'Jinppallola' and 'Romain white', and indian lettuce), two of Brassica(tatsoi and red tatsoi) and amaranth were used as the materials.After sowing, the rice seedling tray was placed in multi bench system(L120×W60×H195cm, 10th floor), which were low(1st) layer above 15cm, middle(4th) layer above 115cm and high(7th) layer above 175cm apart from ground.Irrigation was sprayed 2~3 times a day using a automatic irrigation system.The growth characteristics and leaf color were investigated when leaf vegetables were reached the optimum size(within 10cm of plant height).During the culture periods(29th Jun.~31th Jul.2017), daytime average temperature was 27.4~28.3o C regardless of layers but solar irradiance was higher in the high-layer than low and middle-layer of 37% and 22%, respectively.The leaf length, leaf width and number of leaves in middle and highlayer have a tendency to increase but, fresh weight was different according to the layer.When the correlation between accumulation radiation and growth was analyzed, all of growth factor of Amaranth showed a high correlation and other cultivars showed correlation with each growth factors.As a result, It is suitable that amaranth and red tatsoi for high-layer, Indian lettuce and tatsoi for middle and high-layer and 'Romain white' for middle-layer.The growth of red lettuce 'Jinppallola' was good at low layer, but leaf color expression was poor.So the high layer is suitable for 'Jinppallola'.Additional key words : accumulated radiation, amranth, Brassica spp., Lactuca spp., leaf color, rice seedling tray 서 언 최근 국민 소득 증가와 가족 구성원 감소 등 사회 구 조가 변함에 따라 소비자들의 선호도는 간편함, 소량화, 고급화, 다양화 등으로 변하고 있다.그로 인하여 신선 편이 농산물의 시장규모는 5,870~6,890억원으로 전체 농 산물 시장의 3
