Abstract

Porang (Amorphophallus muelleri) represents one of Indonesia's rich tuberous biological resources, functioning as a plant that yields carbohydrates, fats, proteins, minerals, vitamins, and dietary fibers. Porang has long been employed as a raw material in the food industry, notably in konnyaku production. However, this plant's growth is often suboptimal, especially when cultivated in nutrient-poor soils like red-yellow podzolic soil. This study iaims is to understand the interaction and find the best combination of solid guano fertilizer (GF) and liquid organic fertilizer (LOF) on the growth of porang in red-yellow podzolic soil. The study was conducted experimentally using a complete randomized design (CRD) factorial comprising two factors. Factor G (GF) and factor T (LOF) had three levels. The data collected was statistically analyzed using variance analysis, followed by Duncan's new multiple range test (DNMRT) at the 5% level. The study results indicate that applying GF and LOF on porang growth significantly influences plant height, stem diameter, leaf stalk number, and lateral root number for each treatment. G2T2 (GF application of 400 g per polybag and LOF of 6 ml/l) demonstrated the best results among all treatments. Furthermore, the interaction between the two treatments significantly impacted the number of leaf stalks and lateral roots. In conclusion, this research provides compelling evidence that the combined use of GF and LOF can significantly enhance the growth of porang plants, particularly in nutrient-deficient soils.
