International Journal of Agriculture, Forestry and Plantation (Malaysia), 13. pp. 270-274. ISSN 2462-1757

Five herbal species, namely Clinacanthus nutans (belalai gajah), Andrographis paniculata (hempedu bumi), Orthosiphon stamineus (misai kucing), Gynura procumbens (sambung nyawa), and Strobilanthes crispus (pecah beling), were planted in two different environments at the R&D Centre, Felcra Nasarudin Belia, Seri Iskandar, Perak. The main objective of this study was to evaluate the potential growth of the herbal species under partial shade and direct sunlight. At the partial shade plot, an intercropping system was applied in which the herbal species were intercropped with oil palm trees, while at the direct sunlight plot, herbal plants were planted in an open field. Monthly measurements were taken to assess the plant growth performances, while the biomass and chemical compounds were examined after the fourth month. The findings indicated that all five herbal species exhibited superior growth and biomass in the open field plantation area. Nevertheless, certain herbal species, like Orthosiphon stamineus, Gynura procumbens, and Strobilanthes crispus, exhibit increased leaf length and width when cultivated in shaded fields. Chemical substances were assessed in each species throughout this study. The study's findings indicate that all five herbal species are recommended for cultivation in open-field plantations to achieve high yield production.

Abstract

Five herbal species, namely Clinacanthus nutans (belalai gajah), Andrographis paniculata (hempedu bumi), Orthosiphon stamineus (misai kucing), Gynura procumbens (sambung nyawa), and Strobilanthes crispus (pecah beling), were planted in two different environments at the R&D Centre, Felcra Nasarudin Belia, Seri Iskandar, Perak. The main objective of this study was to evaluate the potential growth of the herbal species under partial shade and direct sunlight. At the partial shade plot, an intercropping system was applied in which the herbal species were intercropped with oil palm trees, while at the direct sunlight plot, herbal plants were planted in an open field. Monthly measurements were taken to assess the plant growth performances, while the biomass and chemical compounds were examined after the fourth month. The findings indicated that all five herbal species exhibited superior growth and biomass in the open field plantation area. Nevertheless, certain herbal species, like Orthosiphon stamineus, Gynura procumbens, and Strobilanthes crispus, exhibit increased leaf length and width when cultivated in shaded fields. Chemical substances were assessed in each species throughout this study. The study's findings indicate that all five herbal species are recommended for cultivation in open-field plantations to achieve high yield production.
