This study was carried out to determine the effect of various fertilizer levels on the growth and yield of Scutellaria baicalensis Georg cultivated after the barley in the southern coastal areas of Korea under the non-mulching condition by direct sowing culture. The flowering date of medium dressing plot (N;:;P_2O_5;:;K_2O=9;:;13.5;: 9 kg/10a) and heavy dression plot (N;:;P_2O_5;:;K_2O=12;:;18;:;12kg/l0a) were July 23. The flowering date of the medium and the heavy dressing plot was delayed by 3days compared with that of non-fertilizing plot. The growth characteristics such as stem length, diameter of main stem, number of branch per plant, main root length, main root thickness and dry weight of stem leaves were more increased at medium dressing plot than that of other fertilizer levels. The root dry weight of in Scutellaria baicalensis Georg cultivated after barley was highest at the fertilizing plot of N, P_2O_5;:;K_2O = 9 : 13.5 : 9kg/10a. The dried-root yield was 178kg in medium dressing plot, 167kg in standard dressing pot, and 126kg in non-dressing plot. The dried-root yield of medium dressing plot was 7% and 41% higher than that of standard dressing pot and non-dressing control plot, respectively.
