Fish waste is one of the causes of environmental pollution both from its aroma and availability which is left untreated. For this reason, the waste must be processed into something useful as liquid organic fertilizer. The study was conducted with the aim of determining the effect of liquid organic fertilizer of skipjack fish waste on the growth and yield of mustard plants (Brassica juncea L.). The research was carried out in Gambesi Village, South Ternate City in February – March 2021. The research method used a randomized group design (RAK) with 5 treatments and 4 repeats followed by using the BNT test (Smallest Real Difference) at a signification level of 0.05. The dose treatment of liquid organic fertilizer for skipjack fish waste is R0 = No treatment, R1 = 15 ml / polybag, R2 = 20 ml / polybag, R3 = 25 ml / polybag, R4 = 30 ml / polybag. Observation data of plant height, number of leaves, fresh weight at harvest and leaf area. The results showed that the application of liquid organic fertilizer of skipjack fish waste at a dose of 25 ml / polybag had a significant effect on the parameters of the number of leaves and the fresh weight of mustard plants. Fresh weight monitoring with a dose of 25 ml/polybag provides better fresh weight of mustard plants.Keywords: mustard, liquid organic fertilizer, skipjack fish waste
