In Malaysia, 98% of green waste ends up in landfills. Only 2% of its being composted or recycled. Lack of a clear strategy or guidelines for managing green waste is one of the reasons, as well as the fact that it is frequently composed separately because of its size and volume, which typically resulting to higher disposal cost. This research study was evaluated, the health and growth of the mango tree (Mangifera Indica) by using organic fertilizer (OF) and leaf mold (LM). A total of seven samples of soil were gathered respectively: Plot A1 (control), Plot B1 (OF+LM) manual, Plot B2 (OF+LM) manual, Plot C1 (LM), Plot C2 (LM), Plot D1 (OF+LM) automatic and Plot D2 (OF+LM) automatic to evaluate efficacy of compost organic fertilizer (OF) was determined using two different types of medium: OF and LM and to examine the mango trees' growth and overall health. Samples of organic fertilizer (OF) were gathered at intervals of two weeks over a duration of three months. Physico-chemical biological factors that were examined: pH level, phosphorus (P), total nitrogen (N), total potassium (K), and heavy metal concentration. The data obtained revealed that the growth measurements and NPK contents studied were obviously responsive to the purpose of this study. The best performance in this study was observed in D1 and D2, followed by B1 and B2, then C1 and C2. Conversely, the minimum values for the abovementioned parameters were typically observed in plot A1. The result indicates that a combination of OF and LM improves quality of soil and growth of plants, while NPK concentration content could be a promising alternative for different types of applications. Significant observation has shown that composting OF and LM could improve soil conservation, which indicates adequate results and comparable growth trees compared to chemical fertilizers.
