Effects of Worm Casting level on Growth Characteristics and Yield of Food Canna in Jeju Island

This study were conducted to determine the optimum warm casting rate(0, 100, 200, 300, 400, 500kg/10a) for the yield of food canna in jeju island. The plant height was ranged from 109.4 to 1347cm as organic fertilizer of worm casting increased from 0 to 500kg/10a, but it was no significance between 400 to 500kg/10a. Leaf length, leaf width, number of leaves, number of tillers and bulb per plant were shown higher as the amount of worm casting was increased. Stem diameter were the same trend with plant height response. Fresh yield of food canna increased significantly 134 to 22.6MT/ha as fertilizer rate increased from 0 to 500kg/10a. Fresh weight of above-ground pan and blub were shown the same trend with fresh yield of food canna.
