This study investigated the effect of different livestock manure composts application on yield, soil chemical properties and carbon sequestration in maize cultivation. The experiment consisted of six different fertilizations; no fertilization (control), chemical fertilizer (NPK), pig manure (PM), NPK + residue of maize (NPKR), NPK + pig manure compost + residue of maize (NPKPR) and NPK + cow manure compost + residue of maize (NPKCR). The yield of maize under NPKPR (5,064.0 kg 10a<SUP>-1</SUP>) and NPKCR (4,183.7 kg 10a<SUP>-1</SUP>) were higher than that of NPK (3,775.6 kg 10a<SUP>-1</SUP>). In soil chemical properties, pH, EC and Avail. P<SUB>2</SUB>O<SUB>5</SUB> were increased when livestock compost applied in soil. The content of soil organic carbon (SOC) was higher in order: NPKPR (3.37 g kg<SUP>-1</SUP>) > NPKCR (3.27 g kg<SUP>-1</SUP>) > NPKR (3.12 g kg<SUP>-1</SUP>) > PR (2.88 g kg<SUP>-1</SUP>) > NPK (2.79 g kg<SUP>-1</SUP>) > NF (2.48 g kg<SUP>-1</SUP>). The highest SOC stock was observed in NPKCR (14.67 kg C ha<SUP>-1</SUP>) due to the high SOC and low bulk density. In conclusion, application of livestock manure composts with inorganic fertilizer increase maize yield, SOC stock. Therefore, it is recommendable for suitable soil management strategy to improve soil fertility and increase crop yield in upland soil. Further study might be required to evaluate long-term compost application effect on soil chemical properties and crop yield.
