Effect of Several Application Methods of Yakto on Root Yield in Ginseng Seedlings

This experiment was conducted to determine economic application method of Yakto among 6 application method : amount of Yakto application 3 plots(70 l, 25.5 l, 13.3l/kan), and added side dressing(3 l/kan) each plot. The reduced Yakto application(25.5 l/kan) with side dressing(3 l/kan) showed similar root diameter, fresh weight of roots and yield of good seedlings to standard Yakto application(70 l/kan). And also this application method of Yakto gave similar content of Ca and Mg, but the lower content of N, P, K in roots to standard Yakto application(70 l/kan). These suggested that 25.5 l Yakto application added side dressing(3 l/kan) per kan might be economical application method of Yakto.
