In recent years, the accumulation of heavy metals such as cadmium in soil has increased resulted from various natural processes and industrial activities. Combination of biochar and compost (BioCom) as one of the potential methods in remediating the contaminated soil is not fully understood.  Therefore, the study was conducted to investigate the effects of BioCom on cadmium availability and plant growth. Four treatments with four replications ranging from 0 to 40% of BioCom application were arranged randomly in the glasshouse. The result showed significant at phosphorus concentration in green mustard with 40% application of BioCom. Similar result was found with soil pH which significant higher at pH value of 5.30 as compared to the control. The increasing application rate of BioCom application in soil showed decreasing trend of Cd concentration in soil and green mustard. It is recommended that the BioCom Application have a greatre potential in reducing the cadmium availability and also promoted plant growth with the optimum application rate of 40%.
