ABSTRACT:
Propagation of porang plants is still constrained by the long growth period. One of the propagations of porang plants can use bulbils. The propagation technique is carried out using the application of Growth Regulatory Substances (PGR) and engineering of planting media. The purpose of this study was to determine the growth of bulbils of porang plants (Amorphophallus muelleri Blume.) Madiun 1 variety with the application of NAA (Naphthalene Acetic Acid) and modification planting media. The aim of this research is to determine the growth of bulbils of porang plants Madiun 1 variety with the application of NAA and modification of planting media. The method of porang plant propagation is carried out in vivo. The planting medium consists of a mixture of top soil, rice husk charcoal, and compost. Furthermore, the planting medium is given an application of NAA 100 ppm, 200 ppm and control (0 ppm). This study used a Completely Randomized Design (CRD) with a factorial pattern consisting of 2 factors. The first factor is PGR consisting of 3 levels (0 ppm, 100 ppm, 200 ppm) and the second factor is planting media engineering consisting of 4 levels, namely top soil, rice husk charcoal, and compost with 4 ratios (1:1:1, 2:1:1, 1:2:1, 1:1:2). Data were analyzed using parametric analysis in the form of Two Way ANOVA at a confidence level of 95%. The results showed that the treatment of modification of top soil, rice husk charcoal, and compost (1:1:1) planting media with the application of ZPT (0 ppm) had the highest average value, namely plant height 41.1 cm, stem diameter 4.91 mm, leaf area 439.2 cm2, dry weight 1.94 g, dry weight of the crown 1.53 g, dry weight of roots 0.41 g, root length 8.4 cm, and number of roots 29.
