ABSTRACT

Curcuma aeruginosa is a medicinal plant and essential ingredients in Vietnam traditional medicine. Potassium fertilizer (K) is one of major factor was effect to accumulation of active ingredients on root of plant and overusing chemical fertilizer cause reducing the quality of the products. The goal of study is to find the potassium fertilizer formula suitable for growth and development of Curcuma aeruginosa plant in Vietnam. This study was carried out to find the potassium fertilizer formula suitable for growth and development of Curcuma aeruginosa plant in Vietnam. The result showed that potassium fertilizer with K2 treatment 180 kg K/ha could help Curcuma aeruginosa Roxb to achieve high yield and quality with germination rate reached 80%, the average yield 10.50 – 10.68 tons/ha. The content of Germacrom, Curdion and Furanodiene was 1.11, 0.19 and 0.10 respectively. The content of essential oil was 3.06 ml/100g. The results in the present study also could suggest for the production of Curcuma aeruginosa Roxb obtain the high quality medicinal material in the future.
