Microorganism plays an important role in our life as it helps decompose organic matter into simpler substances to create the natural and ecosystem balance cycle. In the agriculture sector, microorganisms are vital for the soil to harmonize soil to become more fertile. However, the excessive use of chemical fertilizer has made the soil change its biological, chemical, and physical properties and has led to the number one pollution from the agriculture sector to the world. Thus, effective microorganisms use as biofertilizers have gained world attention to practice sustainable agriculture. To study the effects of different formulations of effective microorganisms on microbial populations of chili crops, the experiment was carried out using Complete Randomized Design based on three treatments using different EM and one control using chemical fertilizer with three replications. The control (T0) was AB fertilizer, treatment 2 (T2) was Tapioca EM, treatment 3 (T3) was Rice EM, and treatment 4 (T4) was Bread EM. The chili varieties use Kulai 461 and the EM fertilizer (3ml of different EM + 10ml unchlorinated water) and AB fertilizer (3ml of AB fertilizer + 10ml of unchlorinated water) were applied once a week till week 5. The parameters used in this study were plant height, number of leaves, the diameter of leaves, soil pH, percent of soil organic matter, and microbial population. In this experiment, AB fertilizer (T0) has domain the plant growth development, but it shows the least result for the soil analysis and the microbial population in the soil. On the other hand, using Rice EM fertilizer (T2) shows significantly greater soil analysis and the microbial population is better. The result shows that soil amended with EM fertilizer improves the soil’s microbial population, harmonizes the soil, and creates sustainable agriculture.
