The stolons were then planted under VIETGAP and ORGANIC conditions (see Materials and Methods section for details). The two fields were adjacent, both in full sunlight, and therefore experienced the same meteorological conditions. It was observed that the ORGANIC C. asiatica was growing more slowly, taking about 2-3 weeks longer for the biomass accumulation than the VIETGAP C. asiatica. The leaves of the ORGANIC C. asiatica samples displayed a more vivid green colour (Fig. ) than the leaves of VIETGAP samples (Fig. ). During the 26 months of the study (from the planting in October 2020 until November 2022), fifteen harvests of C. asiatica were collected for each of the VIETGAP and ORGANIC conditions for determination of the percentages of the dry mass from the fresh mass (Fig. and Table ) and the percentage of the ethanol/water raw extract from the dry mass (Fig. and Table ). The leaves used for analysis were selected manually under both growth conditions using the same criteria -not too old, not too young, no visible damage by insects and pests and leaf shape indicative of good plant health.
