Biofertilizers are helpful microbes that make nutrients in the soil available to plants. In this study, a combination of Candida yeast, Azotobacter bacteria, and Bacillus bacteria was tested on mustard plants. The Bacillus Candida combination gave the highest plant height and weight. Azotobacter Candida had the widest leaves, while Azotobacter Bacillus Candida had the longest roots. Using biofertilizers like these can help improve plant growth and reduce soil pollution from chemical fertilizers.
