Growth and Physiological Activity of Green Grass Jelly (Cocculus orbicuatus) Cuttings on the Use of Planting Media Composition and Photosynthetic Bacteria (PSB)

Cocculus orbiculatus is one type of creeping green grass jelly that had many benefits in the health sector and as a food ingredient. The study aims to determine the effect of planting media composition and PSB on the growth of green grass jelly cuttings. This study used a factorial Randomized Complete Group Design (RCGD). The first factor was the composition of planting media, namely soil + biochar (2:1), soil + manure + biochar (1:1:1), soil + manure + biochar (2:2:1), and soil + fertilizer (2:1). The second factor was PSB concentration: without PSB, 10 mL L-1, 15 mL L-1, and 20 mL L-1. Data were analyzed using Analisys of Variance (ANOVA) and Duncan Multiple Range Test (DMRT) further tests at 5% level. The results showed that the use of planting media composition of soil + manure + biochar (2:2:1) with PSB 10 mL L-1 could increase plant height at 6 weeks after planting (146.3 cm) and the number of leaves at 6 weeks after planting. The use of media composition of soil+manure+biochar (2:2:1) can increase plant height, number of leaves, leaf area, fresh weight, dry weight, and chlorophyll content compared to the use of other media compositions. The application of 10 mL L-1 PSB can increase the number of leaves compared to the application of other concentrations.
