Pengaruh Kombinasi Pupuk Organik Dan Pupuk Hayati Terhadap Pertumbuhan, Produksi Dan Mutu Pegagan

Abstract

<em>Gotu kola is one of the medicinal plants that has begun to be cultivated by the Indonesian people. It’s cultivation needs to follow the GAP to produce the qualified yield, including the use of fertilizers. Biofertilizers have been widely developed to reduce adverse effects of chemical fertilizers to the environment, thus an organic cultivation method can be an alternative. The aim of this study was to determine the effect of biofertilizer on growth and yield of gotu kola. This research was an experimental study with a completely randomized design (CRD) using 8</em> <em>planting media treatments consisting of (a) Soil + manure + dolomite; (b) Soil manure + 1 g biofertilizer; (c) Soil + dolomite + 1g biofertilizer; (d) Soil + manure + 3 biofertilizer; (e) Soil + dolomite + 3 biofertilizer; (f) Soil + manure + 5 g biofertilizer; (g) Soil + dolomite + 5 g biofertilizer; and (h) Soil + 3 g</em> <em>biofertilizer. Parameters observed were leaf area, stem length, number of leaves, number of tillers, fresh weight, dry weight and asiaticoside content. The results showed that combination treatment of biofertilizer (1 g) with dolomite (30 g) gives better effect in increasing the number of tillers and number of leaves, while the combination of biofertilizer (5 g) and dolomite (30 g) is the best for asiaticoside levels in gotu cola.</em>
