ABSTRACT

Generally cow dung is used as organic manure to enhance soil fertility in tropical agriculture. Cow dung contains a diverse group of microorganisms such as bacteria, fungi and yeast that canact as aplant growth promoting microbes having traits such as P-solubilization, Znsolubilization. Research revealed that Bacillus subtilis, Bacillus cereus, Trichoderma harzianum and Aspergillus niger isolated from cow dung can increase the growth of plants. Microorganisms in biofertilizers improve the nutrientvalue of soil. The main sources of biofertilizers are bacteria, fungi and cyanobacteria (blue-green algae). The most prominent relationship that these have with plants is symbiosis, in which the associates get benefits from one another. Biofertilizers provides nutrient to the soil and stimulate plant growth by increasing efficient uptake or availability of nutrients for the plants and by suppressing soil borne diseases. Generally biofertilizers supplement nutrients by fixing atmospheric nitrogen, by phosphorus solubilisation, and by producing plant growth-promoting substances.
