Abstract

|
|
|
This experiment was carried out to investigate the effect of several organic compost on the growth and root yield of Angelica gigas Nakai with organic cultivation. After fertilizing the soil with organic fertilizer, the dry weight of liming fertilizer showed a slow change, while microorganism fertilizer decreased about 29% until 20 day after fertilizing. At 110 days after fertilizing, microorganism fertilizer decreased more than liming fertilizer. Liming fertilizer decomposed slowly, while microorganism fertilizer decomposed early on rapidly but gently after 20 days in decomposed rate of organic fertilizer. Dried root yields per 10a of A. gigas were not significance between 277.6 ㎏ in conventional fertilizer and 277.7 ㎏, 280.5 ㎏ in N 1.5, N 2.0 times of microorganism fertilizer. Decursin and decursinol angelate contents in A. gigas were 9.08 ~ 9.07% from N 1.0 and N 1.5 times in liming fertilizer, and 7.94 ~ 8.12% from N 1.5 times and N 2.0 times in microorganism fertilizer, compared to 7.31% of conventional treatment.
