Porang (Amorphophallus muelleri Blume) is a tuber plant that has excellent potential because it is packed with nutrients and advantages. To boost porang yield and preserve soil fertility, liquid organic fertilizer must be used. The study’s objectives were to determine the ideal dose for porang growth and yield and to assess the impact of liquid organic fertilizer. From March to August 2021, the study was conducted at BKPH Pojok in Kemadohbatur Village, Tawangharjo, Grobogan. The dose of liquid organic fertilizer (LOF)was 0.375 ml/plant, 0.75 ml/plant, 1.125 ml/plant, and control with a total of 6 replications in the study’s one-factor RCBD design. Growth metrics (plant height, stem circumference plant fresh weight, plant dry weight) and yield parameters (number of bulbil, bulbil weight, rhizome fresh weight, rhizome diameter, rhizome storage weight, and rhizome volume) are observational parameters. Data processing using ANOVA test level 5% followed by regression test. The results showed that the LOF dose of 0.75 ml/plant tended to increase plant growth and yield.
