Kenaf(Hibiscus cannabinus L.) was grown at six planting densities(50 x 40㎝, 50 x 30㎝, 50 x 24㎝, 50 x 20㎝, 50 x 17㎝ and 50 x 15㎝) from 25 April to 25 Sep. in 1999 at Jeju island to determine the optimum plant density. As plant density increased, from 17 to 43 plants per ㎡ plant height increased linearly from 252.2㎝ to 295.1㎝. As planting density increased, the number of leaves, branches and stem diameter was decreased but the number of withering leaves increased. Increasing plant density from fresh forage yield, dry matter (DM) yield, crude protein (CP) yield and total digestible nutrients (TDN) increased from 75.8MT/ha to 95.5MT/ha, from 14.9MT/ha to 18.3MT/ha, from 1.9MT/ha to 3.0MT/ha and from 7.6MT/ha to 11.1MT/ha, respectively. However, no significant differences in these yields were found between 50 x 17 and 50 x 15㎝. Increasing plant density from 50 x 40 to 50 x 15㎝, leaf out of CP, crude fat (CF), nitrogen free extract (NFE) contents increased from 19.3% to 23.5%, from 4.7% to 6.2%, from 37.0% to 42.1 %, respectively. However, increasing plant density from 50 x 40 to 50 x 15㎝, crude fiber and crude ash contents decreased from 20.8% to 17.6%, from 9.0% to 8.2%.
