ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of various planting densities on dynamic growth and root yield of Isatis indigotica.</p><p><b>METHOD</b>The planting samples were collected to measure the growth period of each organ.</p><p><b>RESULT AND CONCLUSION</b>Under different planting densities, both main root length and breadth exhibited a trend of "fast-slow" by stages. However, the number of individual plant leaves were showed a trend of "slow-fast" on growth period. Meanwhile, the leaf length and breadth were exhibited a trend of "increase-decrease". The increase of dry leaf, dry root and whole plant dry matter was faster during the period of 65-76 days after seeding. The differences of root and leaf yields under various densities were significant. Planting densities has a great effect on yield of root. It must be shown that there was a positive development between the individual plant and colony. According to the dry matter of root and leaf, treatment B (i.e., 7 cm x 25 cm) was good choice.</p>
