The objective of this study was to determine the effect of applying liquid organic fertilizer on the growth and biomass production of elephant grass (Pennisetum Purpureum). This study used a completely randomized design consisting of 4 treatments and 4 replications. The study treatment was liquid organic fertilizer (LOF) from various manufactured products, namely Genetic-plus and Bio-love, and as a comparison, LOF Bio-urine produced from the biogas process. The research treatment is as follows: T0 = Without using LOF (Control); T1 = Using LOF Genetics- plus; T2 = Using LOF Bio-love; T3 = Using LOF Bio-urine. Parameters measured were (1) plant growth, namely plant height and tiller number, (2) biomass production, namely fresh matter weight, dry matter weight and leaf blade percentage and (3) nitrogen uptake. The results showed that the treatment had a very significant effect (P<0.01) on growth and biomass production, and a significant effect (P<0.05) on nitrogen uptake. The highest yield for plant height growth reached 446 cm and the growth of tiller number reached 39 tillers. The highest yield in the production of fresh matter weight was 40 kg/m2 and dry matter weight was 688.2 gr/m2. The highest leaf blade percentage obtained was 65% in LOF Bio-love. In summary, using liquid organic fertilizer on elephant grass was more effective and efficient on LOF Bio-urine compared to Genetics-plus and Bio-love. In short, The use of manufactured liquid organic fertilizer also has a positive effect on increasing growth and elephant grass biomass production. © 2023 by the authors.
