The sustainability of chili production is influenced by plant pest disturbances, for which farmers strive to suppress chili plant pests by using high chemical pesticides. The application of environmentally friendly chili cultivation such as using biofertilizer is needed to suppress negative impact for environment and chili quality. This study aims to determine the effect of Agrimeth biofertilizer application on chili yield and population of Nitrogen Fixing Bacteria. The study was conducted in

The study used a factorial randomized two-group design with a combination treatment of three chili varieties and three frequency of agrimeth biofertilizer applications, and each treatment replicated three times. Plant parameters observed included plant height, number of fruit/plant/season, weight of fruit/plant/season, soil analysis, analysis of nitrogen fixing bacteria population at the end of the study. The results showed that the application of agrimeth was not significantly different on average of plant heigh . The treatment of the application of agrimeth 1 time a season produced the highest number of chili fruit (574 pc) and weight of chili (2.09 kg) per plant per season, significantly different from the treatment of the application of agrimeth 2 and 3 times per season. The highest population of nitrogen fixing bacteria was occurred in treatment of agrimeth applied 3 times.
