Curcuma aromatica Salisb is an important medicinal herb in Vietnam. It is exploited naturally, so its production is limited and in danger of extinction. Studying an organic farming model is a necessary orientation to exploit, conserve and provide quality raw materials.
The present study was conducted to investigate the effect of surface coating types (A1: without coating, A2: straw coating and A3: polymer coating) and organic fertilizer amount (B1: 0; B1: 15, B2: 20, B3: 25 and B4: 30 ton ha−1) on growth and yield of Curcuma aromatica Salisb. The experiment was designed in a factorial randomized complete block design (RCBD) with three replications. The traits studied were: survival plant's rate (%), leaf area (cm2), plant height (cm), number of leaves, fresh weight (g/plant), Dry weight (g/plant), phenolic content/area (mg/20 m2), curcumol content/area (mg/20 m2).
The results of the experiment revealed that surface coating types and organic fertilization and their interaction were significant in growth and yield of Curcuma aromatica Salisb.
