Available arable land is limited and the nitrogenous fertilizers are polluting the environment. Currently the use of biofertilizers in crop production is gaining importance to reduce the pollution. It is important that cropping systems must be developed which do not rely on inorganic nitrogen based fertilizers. The Azolla is a well-known biofertilizer as an alternate source for the nitrogen based fertilizers. Since its rapid growing, N -fixing symbiosis, potential productivity phenomenon helps the farmers to reduce nitrogen based fertilizer application cost. Besides, due to its nutritional property, it can be used as feedstock for the animals such as poultry, pigs, dairy, fish, goat, and sheep.
