EFFECTS OF VERMICAST-ENRICHED GROWING MEDIUM ON QUALITY AND CHLOROPHYLL CONTENT OF MEDICINAL ALKALINE HERB (GYNURA PROCUMBENS)
Alkaline herb (Gynura procumbens) is one of the medicinal plants with many health benefits. This study was conducted to determine the effects of growing medium supplemented with vermicast on the quality and chlorophyll content of the herb. Three growing media were used; garden soil alone (control), 25% vermicast + 75% garden soil, and 50% vermicast + 50% garden soil. Prior to planting of cuttings in the different growing media, alpha naphthalene acetic acid and vermitea were applied to promote rooting. Growing media with vermicast increased the leaf surface area and chlorophyll content compared to the control plants. Plants grown in medium with 50% vermicast had the highest chlorophyll content of 171.12 ml/g fresh weight with highest visual quality rating. Green color quality and lightness (L*) were not significantly affected.
