This study was conducted to investigate the effects of cultural soil textures on growth and quality of Glycyrrhiza uralensis Fischer from 2009 to 2010. The obtained results from this study were summarized as follows; The growth of stem and leaf were superior to one year old G. uralensis, and surface runner and root growth tended to be better in 2 years old G. uralensis. The weight of stem and leaf were heavy in sandy loam, and plant height, branches, stem diameter in sandy clay loam were better than other soil texture. The growth characteristics, such as length, number and weight of surface runner, was better in order of sandy clay loam greater than sandy loam greater than loamy sand. The length of main and lateral root was longer in loamy sand soil than other treatments, and the diameter of main and lateral root was more thicker in sandy loam than others. The number of lateral root was higher in the sandy loam than other treatments. The yield of main and lateral root was in order of sandy loam greater than sandy clay loam greater than loamy sand soil. Marketable root yield of one year old and two year old G. uralensis were increased 57% and 71% in sandy loam compare to a loamy sand as 204 kg/10 a, respectively. The content of glycyrrhizinic acid was the hightest as 1.62% in sandy clay loam soil in one year old, and as 1.58% in sandy loam soil in two years old of G. uralensis, respectively.
