Abstract: There are several types of fertilizers that are commonly used in the agriculture sector either organic or chemical fertilizer. The application of organic fertilizer is a common practice used in the agriculture sector. Today, the application of inorganic fertilizer is widely used in large scale sector. The continuous application of this type of fertilizer contributes greatly to soil degradation. Hence, a study was conducted to determine the effect of amended soil with oil palm empty fruit bunch (EFB) compost and fish meal on the growth of Choy Sam (Brassica chinensis var parachinensis). This experiment was conducted at the shaded and closed area to prevent and minimize the factors that can affect the results. The experiment also was conducted by using Completely Randomized Block Design (CRBD) with three treatments replicated for three times. The treatments were treatment 1: combination NPK fertilizer and EFB compost, treatment 2: fish meal and EFB compost and Treatment 3: 100% EFB compost. The soil pH and soil moisture was determined before and after treatments. The growth performance was determined by the plant height, leaf area and biomass. The three treatments had not changed the pH condition after a crop of Choi. However, the combination of NPK fertilizers and EFB compost showed the best growth performance.
