This experiment was carried out to investigate the effect of several organic fertilizers on the growth and root yield of Liriope platyphylla was planted 30 cm ${\time}$ 10 cm in field from 1998 to 1999. Six treatments of organic fertilizers applied : N.P.K, NPKC (N,P,K+Compost), NPKCO (N.P.K+Compost+Oilcake),NPKCOF (N.P.K+Compost+Oilcake+Fowldropping), NPKCOFP (N.P.K+Compost+ Oilcake+Fowldropping+plant ash), CO (Compost+Oilcake), COF (Compost+Oilcake+fowldropping). Organic matter, available phosphate, and MgO are NaO of soil increased in all of plots with the addition of organic fertilizers. The leaf length, number of leaves and of tillers were increased by the use of organic fertilizers compared to N.P.K fertilizers compared with N.P.K fertilization. The number of tubers were increased by using the organic fertilization N.P.K fertilization and showed higher in the soil depth of 0${\sim}$20 cm. The dry root yield was showed higher in organic fertilizers than in N.P.K fertilizer and highest dry root yield resulted from NPKOF 39% and NPKCOFP 49%.
