Abstract
This study was conducted to find out the changes in the growth and yield of ginseng and the changes in the soil of direct-seeded ginseng fields after applying different compaction strengths. As a result of surface soil compactions, the topsoil hardness increases as the strength of treatment increases in the first year but topsoil hardness increased only by applying 30 kg weight of compaction in the second year. The germination rate was significantly higher (79.4% and 79.1% at 25 kg and 30 kg, respectively) in 1st year after the application of soil surface compactions. The longest plant was 35.7 cm in 4- years old ginseng in the control and the height was 26.9 cm and 26.5 cm in the soil surface compactions of 25 kg and 30 kg, respectively. In addition, the higher weight of ginseng roots of 31.3 g and 30.3 g were observed after applying 25 kg and 30 kg compaction treatment, and the lowest root weight of 25.6 g was in the control. Therefore, it is shown that after sowing, applying the weight of 25 kg to 30 kg for soil surface compaction is appropriate for better yield in direct seeded cultivation of ginseng at paddy fields.
