<![CDATA[Soybean productivity in Indonesia remains relatively low, partly due to declining soil fertility. One approach to address this issue is the application of liquid organic fertilizer (LOF) and phosphate fertilizers, such as SP-36. This study aimed to evaluate the effects of various concentrations of banana corm-based LOF and different doses of SP-36 fertilizer, as well as their interaction, on the growth and yield of soybean plants (Glycine max L.). The research was conducted in Medokan, Surabaya, using a two-factorial Randomized Block Design (RBD) with four levels of LOF concentration (0, 500, 600, and 700 ml/l) and three levels of SP-36 concentration (150, 200, and 250 kg/ha). The observed parameters included plant height, number of pods, percentage of empty pods, seed weight per plant, seed weight per hectare, and fruit set. The results indicated a significant interaction between LOF and SP-36 on plant height 42 days after planting, number of pods, percentage of empty pods, and fruit set. The most effective treatment was the combination of 600 ml/l banana corm LOF and 200 kg/ha SP-36. However, seed weight per plant and hectare did not show a significant effect. This study concludes that the appropriate combination of banana corm LOF and SP-36 fertilizer can significantly enhance soybean growth and yield. It is recommended to use 600 ml/L of banana corm LOF combined with 200 kg/ha of SP-36 fertilizer to optimize plant height, number of pods, and fruit set in soybean cultivation.]]>
