The tobacco seedlings were cultured in nutrient solution which have the concentration of 40 p.p.m. N, 10 p.p.m. P and 40 p.p.m. K. The capacity of one tray for water culture was about 15 l. 62 seedlings were cultured in the tray and the aeration was continued for three hours a day by the 1/4 horse Power aircompresser. As the plant thus grown is comparable to those raised in the nursery bed in Okayama Tobacco Station, it is concluded that the apparatus and procedure here reported are adequate for growing tobacco seedlings.
