This study aims to obtain the best combination of decanter cake (DC) and organic materials,chicken manure (PKA) on soybean growth and yield at Ultisols.. The research design used wasa Randomized Block Design, with treatment of combination of DC and PKA. The treatmentswere control (recommended inorganic fertilizer: 100 kg / ha NPK), DC 15 ton / ha + PKA 0 ton/ha, DC 10 ton / ha + PKA 5 ton / ha, DC 7.5 ton / ha + PKA 7 , 5 ton / ha, DC 5 tos / ha + PKA10 ton / ha, DC 0 ton / ha + PKA 15 ton / ha. Parameters observed: Number of productivebranches, number of pods per plant, number of filled pods, soybean grain yield . The dataobtained were analyzed by means of variance and DMRT at the 5 percent level. The resultsshowed that the combination of DC and PKA could improve soil chemical properties, and hada significant effect on the number of productive branches, yield components and soybean yield.The best combination for the highest soybean yield was the combination of DC 5.0 tonnes / ha+ PKA 10.0 tonnes / ha.
