Agriculture is critical to a country's development and existence, thus preserving its quantity and quality is critical for feeding the people and exporting goods. Pesticides and chemical fertilizers are used in modern agriculture with the goal of boosting global food production. As a result, they act as a quick source of nutrition for plants, enabling them to develop more quickly and effectively. Fertilizers, although necessary as a nutritional supplement for plants and mostly composed of nitrogen (N), potassium (K), and phosphorous (P), can pose a number of health risks. Researchers have discovered that “bio fertilizer” is a great alternative to chemical fertilizers that supply nutrients through nitrogen fixation, phosphorus solubilization, and plant development by the production of growth stimulating essence. Based on relevant literature and research work conducted by many researchers, the study examines these constantly available and environmentally friendly nutrients, kinds, and their potential for crop development.
