摘　　要：This study aims to determine the ability of CM(Cow Manure)combined with RHA(Rice Husk Ash)to provide a significant effect on the growth and production of soybean planted in an ultisol.It was conducted in a pot experiment at the Experimental Site of the Faculty of Agriculture,Sriwijaya University,Indralaya,Indonesia between September 2019 and February 2020 using completely randomized design factorial with two factors which were two rate levels of RHA at 3.75 and 7.5 tons·ha^(-1) and three rate levels of CM at 0,10,and 20 tons·ha^(-1).It is important to note that each combination was repeated three times,thereby,leading to a total of 18 pots.The variables studied were plant growth and yield which are represented by plant height,the total number of pods,number of filled pods,seed weight per plant,and soybean produced.The results showed that CM combined with RHA was effective in increasing nutrient availability and reducing soil acidity.It was discovered that CM had a significant effect on soil pH,plant height,the total number of pods,number of filled pods,seed weight per plant,and soybean produced while RHA did not have any significant difference on all the variables observed.However,the combination of 10 tons·ha-1 CM with 3.75 tons·ha-1 RHA was observed to be the best combination treatment to increase the growth and production of soybean in ultisol as indicated by its ability to produce 2.58 tons·ha^(-1) soybean.
