Abstract : Ginger (Zingiber officinale Rosc.) belongs to a tropical and sub-tropical Zingiberaceae family, which originated from Southeast Asia. Ginger is one of the most widely used herbs contains several interesting bioactive constituents including [6]-gingerol that has potent antioxidant activity and health promoting properties. Substrates plays an important role for plants to growth in the soilless culture system. Given the nature of the substrate may play a crucial role in determining water and nutrient availability for the plant and hence may affect the metabolic pathways involved in the synthesis of specific biochemical compounds, this study was conducted to determine the effects of organic soilless substrates such as coir dust and burnt paddy husks on ginger growth, yield and [6]-gingerol content using soilless culture system. The treatments were arranged in a randomized complete block design (RCBD) with five levels of treatment with three replicates. The treatments include, T1 = 100% coir dust;
T2 = 100% burnt paddy husks; T3 = 70% coir dust and 30% burnt paddy husks;
T4 = 30% coir dust and 70% burnt paddy husks; and T5 = 50% coir dust and 50% burnt paddy husks. Results showed that plant in T1 gave rise to highest rhizomes yield (5480  325 gm) compare to other treatments. Media containing high amount of coir dust (70 – 100%) showed good growth and increased the rhizome yield up to 36% compared to those containing high amount of burnt paddy husks. There was no significant difference between all treatments in term of [6]-gingerol content in the fresh and dry ginger rhizomes. The studies suggested that the secondary metabolites like [6]-gingerol content and accumulation were not affected by the substrates. It can be concluded that 100% coir dust are the best substrates for growing ginger in soilless culture system.
