Abstract

Soybean is a promising crop that requires further development due to its significant market potential both locally and for export. Soybean cultivation is not widespread in South Sumatra, and production levels remain low. One strategy to enhance production is to utilize fish waste to create liquid organic fertilizer (LOF) by optimizing the type and dosage of fish waste used. This research aims to identify and determine the most suitable type and dosage of fish waste LOF for promoting the growth and yield of soybean plants. This study was conducted on a farmer's land on Jl Sukarela KM 7, Sukarami District, Palembang City. A field experiment method was employed, utilizing a split-plot design. The first factor (main plot) consisted of the type of fish waste LOF, which included a control group, LOF from marine fish waste, and LOF from river fish waste. The second factor (sub-plot) is yet to be detailed. The dosage of LOF fish waste was 10.0 ml/L, 200 ml/L, 300 ml/L, and 400 ml/L. The observed variables included plant height (cm), flowering age (days after planting), number of productive branches, number of pods per plant, number of filled pods, seed weight per plant (g), weight of 100 seeds (g), and seed weight per plot (g). The study results were obtained by tabulating the combinations of different types of liquid organic fertilizers derived from marine fish waste. The dosage of 300 ml/L yielded the highest soybean production, which was 451.00 g/plot, equivalent to 1.80 tons/ha.
