Effects of different light levels on the growth traits and yield of Centella asiatica.
The growth patterns and yield of Centella asiatica plant under four different levels of shading 0% (full sunlight), 30, 50 and 70% of solar radiation interception were investigated. The plantlets were grown in earthen pots containing soil, sand and vermicompost (1:2:1) and submitted to different levels of shading and of solar radiation and full sunlight, as control. The results suggested that plants submitted to 30% shading showed higher plant biomass. However, the plantlets root system showed higher dry biomass under full sunlight. This information is helpful in planning cultivation of the plant.
