Abstract

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.
