Abstract

This research was conducted to investigate the influence of variouis organic substrates on growth and yield of organically grown ginseng seedlings in a shaded plastic house. In the investigation of optimal substrate, the eight substrate were formulated by adjusting blending rate of peatmoss, perlite, coir dust(coco peat), and vermiculite. Then, the changes in physico chemical properties of root substrates as well as their influences on the growth characteristics and yield were determined at six months after sowing. The elevation of the blending rate of peatmoss from 50% to 70% with decrease in the rate of inorganic component (mixture of perlite and vermiculite) from 50 to 30% resulted in the increase in container capacities and decrease in total porosities and air-filled capacities. The concentrations of $NH_4-N$, $P_2O_5$ and K increased as the incorporation rate of castor seed meal, phosphate ore, and langbenite, respectively, were elevated during the root medium formulations. The PPV-1 and PPV-4 substrates produced high stem length, stem diameter, shoot fresh weight, leaf area and root length among eight substrate. Root fresh weight was heaviest in PPV-4 compound nursery media. The results of this experiment will be utilized in the new substrate application for ginseng organic culture in shaded vinyl house.
