Abstract
Background and Objective: Centella asiatica (L.) is a herb that belongs to the Apiaceae family. It can be used for medical purposes and as a cosmetic product. C.asiatica contains many essential substances that have the effect of killing bacteria and fungi, as well as reducing inflammation. This study cultivated C. asiatica in a hydroponic system, using different nutrient solution formulations to investigate growth and high levels of essential substances.
Methodology: The experiment was conducted as a 3 x 3 factorial in a completely randomized design with three replicates. C. asiatica (L.) species from three growing areas, Ubon Ratchathani, Rayong, and Nakhon Pathom provinces, were grown in a hydroponic system using three different nutrient solutions. Analysis of asiaticoside and madecassoside content was performed after a 60-day harvest.
Main Results: The growth of C. asiatica (L.) was influenced by the interaction between the planting site and the nutrient solution. The Ubon Ratchathani and Rayong planting areas provided under the formula 1 solution showed the highest growth in root length, leaf width, leaf length, number of leaves per plant, stem length, and yield per plant. In addition, C. asiatica (L.) grown in Nakhon Pathom, which was provided under solution formula 1, resulted in the highest amount of asiaticoside and madecassoside, which were 34.30 and 41.47 ppm, respectively.
Conclusions: Planting site of C. asiatica (L.) and plant nutrient solutions had a synergistic effect. Solution formula 1 is suitable for growing C. asiatica (L.) in terms of growth and provides many essential substances. It has a lower cost than the control formula, by up to 85 Baht per 10 L, but can provide higher fresh yields and add more essential ingredients to some crops than the control formula.
