Effects of Nitrogen Levels on Growth, Yield and Quality of Curcuma aeruginosa Roxb.

Nitrogen factor (N) is one of important major effect to yield and quality of Curcuma aeruginosa Roxb. The purpose of this research was to find the nitrogen fertilizer formula that is suitable for growth and development of Curcuma aeruginosa Roxb. in Vietnam. The result indicated that application of 150 kg N/ha could help Curcuma aeruginosa Roxb. to achieve high yield and quality with germination rate reached 80%, the time from planting to finishing sprouting was 20-25 days, time from planting to harvesting was from 252 to 260 days; The average plant height was 184.89 cm; number of leaves/main stem was 9-10 leaves; The average number of branches/cluster was 3-4 branches; the average yield was 8.87 - 10.37 tons/ha. The content of essential oil was 3.12 - 3.48 mL/100g; the yield of Germacrom content was 15.364 kg/ha; the yield of Curdion was 53.494 kg/ha; The yield of Furanodiene was 8.756 kg/ha. The results in the present study also could enable the production of Curcuma aeruginosa Roxb. obtain the high quality medicinal material in the future.

Keywords: Curcuma aeruginosa Roxb., Nitrogen dosage on growth, Yield, Essential oil.
