Abstract

The effects of fertilizer levels on the growth and tannin accumulation in a medicinal plant, Geranium thunbergii were determined on the potted plant with both deficient and excessive fertilizer applications.The standard rate of three fertilizer nutrients was established at ratios of 1.6 g ammonium sulphate (N element), 1.4 g superphosphate (P element).and 0.7 g potassium sulphate (K element), per crop.A reduction of dry matter production was 30-50% in plants with deficient fertilizer rates, but tannin concentration in leaf blades did not differ.The application of nitrogen fertilizer stimulated the increase of dry weights, which were also increased with the compound fertilizer containing N, P, and K elements.At higher application rates of 5 to 10 times the amount of nitrogen from standard treatment increased the obvious yield of dry weight more than 2-fold to 4-fold compared with the standard.However, tannin concentration in leaf blades decreased about 5 to 23% in all excessive applications of fertilizer.
