Biofertilizer is made from materials with containing functional bacterias to facilitate nutrient providing for plants. This study aims to evaluate the effective of using biofertilizer on soybean plants (Glycine max). Plant’s biomass and rate of growth were tested and evaluated on field scale. Microbe population was calculated using plate count method. Nitrogen nutrient were analysed using Kjeldahl, and P method using spectrophotometer device. Data were analysed using full random program. The significance rate was evaluated using DMRT 5%. The fertilizer’s dosis are urea 50 kg/ha, SP-36 100 kg/ha, KCl 100 kg/ha and compound biofertilizer 50 kg/ha. Compost’dose and dolomite’s dose are 7.5 ton/ha (dry weight) and 5.79 ton/ha (1.5xAldd) respectively. The results show a real increase of high PH treatment plants during harvest, the plant’s dry weight, nitrogen uptake, the levels of nitrogen, phosphorus uptake, and effective nodule as well as effective than the control and standard fertilizers. Statistically, provision of biofertilizer doesn’t affect the dry weight of wet weight of seed, seed, seed number per plant as well as the weight of 100 seeds compared with standard fertilizers as well as controls. Biological fertilizers tend to increase the population of fungi, bacteria, Rhizobium, and larger than MoPF standard fertilizers. The soil microbe population decreases from 45 DAP into 90 DAP.
