Centella asiatica is ranked among the top few wonder herbs for its medicinal properties. It acts as a panacea for a number of ailments and diseases. The present study revealed with an objective of studying appropriate harvesting intervals in two different ecotypes of Centella asiatica for leaf yield. Field experiment was conducted in kharif season in the campus of botanical garden at St. Columbas College, Hazaribag, Jharkhand. The treatment included three harvesting intervals in 6, 9 and 12 months after sowing with two different ecotypes of small leaf and big leaf, replicated in quadruplicate in factorial randomized block design. The result indicated that among harvesting interval the dry weight of leaves was higher at all harvest interval in the big leaf ecotype compare to the small leaf type. Further, it was also observed that the accumulation of dry weight of leaf was low at 6 months of planting, gradually increased and reached a peak at 12 months in two ecotypes of Centella asiatica.The contents of Ca, N, P and K were higher at all stages of harvest in the big leaf ecotype 1s compared to small leaf ecotype.
