Growth and yield responses of three accessions of Centella asiatica grown in lowland under varied watering intensities

C. asiatica presented the best vigor when planted at an altitude of 2500 meters above sea level. Drought is the main environmental stress in C. asiatica cultivation. The objective of this study was to determine which accession of C. asiatica that grows and produces optimally under stressed conditions since no known accession can grow optimally with various drought stresses. The study conducted in a screen house, Jumantono, Universitas Sebelas Maret Surakarta, from 4 May to 5 August 2019. The research used a completely randomized design with a variety of C.asiatica accessions (accession 1, 2 and 3) as the first factor and variety of watering intensities (once a day, once every two days, once every three days, and once every four days) as the second factor. The results showed that there was an interaction between accessions and watering intensity only on the number of tillers. Accession 1 was a drought-tolerant accession because it grew optimally in almost all variables. Watering intensity once a day was the optimum treatment for C. asiatica growth.
