This study was carried out to determine the effect of sowing time on the flowering, growth and yield of Scutellaria baicalensis Georg, which was collected from Yeochon district, cultivated after barley in the southern coastal areas of Korea. Emergence and flowering dates in the sowing time of June 1 were earlier than those of the other sowing times. In the sowing time of June 1, length and diameter of main stem, number of node per main stem, number of branch per plant and dry weight of stem leaves were greater than those of sowing times of June 10 and June 20. Yield components such as main stem length and diameter, main stem numbers, branches per plant, dry weight of stem leaves, main root length and thickness, number of large root and fine root per plant, and dry weight of root were the highest at the sowing time of June I as the yield of 71.3kg/10a. Optimum sowing time of Scutellaria baicalensis Georg cultivated after barley was June 1 in southern areas of korea.
