초록
The present study was investigated the effect of planting density on plant growth and yield of Panax ginsengC. A. Meyer. Sowing density is one of the most important factors affecting yield. The value of roots have affected by shape,color, weight and degree of disease injury in ginseng. Also, it needed to minimize elapsed time for 5 years including preplantingfield management and cultivation period. We were conducted to evaluate that planting densities and varieties onthe growth, yield and missing rate. The direct sowing was treated seeds density as a four levels (seeds; 72, 90, 120, 144) and10 different varieties with 3 years old ginseng roots. Root weight was significantly affected by planting density and variety,but the number of lateral root and yield were affected by only planting density. Growth index was related to variety andplanting density. Also, Root shape index was affected by both varieties and planting densities. Suitable planting density andvariety were 120 plant per 1.62 ㎡ and Gopoong, respectively. Results showed that it was also a significant difference(p = 5%) in variety of planting density on growth.
