Background : This study for the stable production and supply of seeds of Angelica gigas Nakai(Man-chu Korean Angelica), when seeds harvested using nets, seed productivity was investigated. Methods and Results : Planting density is 50 × 25cm, Fertilizer per 10a was sprayed amount of N-P2O5-K2O = 16-17-10kg. And the amount of compost per 10a was sprayed 3000kg. Seed harvesting nets were used for a time formed the endosperm of the seeds (later in mid-August to late). And net for seed production was used for onion nets (at least 13 × 18cm). Shoot growth conditions were as follows. Bolting rate was 89.0% in the untreated, the treated group was 93.1%. The length and thickness of each stem was 129.3 ~ 130.8cm, 1.8cm. The number of nodes per plant was 6.7 ~ 7.5 pieces, and the number of petiole was 14.8 ~ 15.5 per plant. The number of umbel was 10.3 ~ 11.1 piece per plant, and number of deleted umbel was 7.1 ~ 7.2 piece. Seed weight per plant was 24.2g of the net treatment, but ripening seeds 19.6g, 1000 grain weight were all treated and untreated 2.8g. The total seed weight per plant, the net treated was 24.2g, was the weight of the ripening seeds 19.6g. The weight of the ripening seeds were heavier than those of the control. However, the weight of 1000 grain were both treated and untreated 2.8g. When treated nets, the total seed yield per 10a was 88.0kg production, increased by 60.9% compared to untreated. In addition, the ripening seed production per 10a was 71.5kg production, increased by 50.1% compared to untreated. Researching after germination Seed Production, germination rate was 50.8% in the control group and the treatment group was 54.9%. When applying the germination rate, high-quality seed production per 10a was able to produce 39.2kg, compared to control obtain the results increased by 65%. Conclusion : Through the above results, When producing angelica seed, use of net for seed production is thought to be used as a way to prevent early shattering and insect damage.(True bug, etc.).
