What is Symbion-N?

Symbion-N is a bio-fertilizer based on the selective strains of nitrogen-fixing beneficial bacteria such as Rhizobium, Azospirillum, Acetobactor and Azotobactor. This is available in liquid (1x109 bacterial cells/ml) formulation.

Mode of Action

Rhizobium: This is a nodulating type of micro-organism associating symbiotically with the root of the legume plants. It produces nodules and multiplies in it. By remaining inside the nodules it fixes atmospheric nitrogen.

Azospirillum: It is an associative type of microorganism capable of colonizing root surface of plant. By establishing a symbiotic association ship, it helps plant in getting nutrient 'N' (Nitrogen) from the atmosphere.

Acetobacter: It is an endotrophic micro-organism capable of living inside the plant tissues. It can live in high sugar levels that exists in sugarcane tissues

Azotobacter: It is a free living nitrogen fixing bacteria, lives freely in soil and multiples by making use of the organic matter, as source of carbon (energy) for its growth and existence.

All these Bio-fertilzers fix the atmospheric nitrogen through the process of biological nitrogen fixation and make it available to plant in an easily assimilable and utilizable form.

Dose and Method of Application

Seed Treatment (10 ml 1 kg of Seeds): Seed required for 1 hectare is to be treated with Symbion-N at the specified rate by adopting either seed dipping or seed coating methods.

Treatment in Mechanical Seed Treater: (10ml/1kg of Seed): Symbion-N at the recommended rate is to be mixed well with sufficient quantity of sticking agent/water. Seeds are then treated with this culture mix in a seed treater in a manner so that all seeds are coated with culture slurry properly. The seeds are then shade dried and sown immediately.

Seedling Treatment (100 ml in 10 Litres of water): Symbion-N is mixed with sufficient quantity of water and organic fertilizer or field soil to form a slurry and seedling roots are then immersed in this slurry for about 30 minutes before planting so that the roots are well drenched with slurry.

Sugarcane Sett Treatment (100 ml in 10 Litres of water): Symbion-N(Acetobactor ) is mixed with sufficient quantity of water and organic fertilizer or field soil to form a slurry. Sugarcane setts are then soaked in this mix for about an hour and planted in the fields.

Soil Application (3.0 ltrs in 1000 kg of organic fertilizer): Symbion-N and organic fertilizer or field soil mixed at he recommended rate has to be applied uniformly in the soil and watered well.

Drip System: In places where drip irrigation system is in practice the liquid formulation of Symbion-N can be used @ 3 liters / ha in 500 liters of water.

Tree Treatments: Symbion-N (Azospirillum) at the specified rate is to be mixed with required quantity of water and applied nearer feeder root zone / nearer tree trunk following pan irrigation, drip irrigation and the like. The treatment is to be done 2 or 3 times a year. The dosage of Symbion-N varies according to varieties, age, and size of tree and its canopy.


  • Symbion-N harnesses atmospheric nitrogen and makes it available directly to plant. It enhances root proliferation through release of growth promoting hormones.


  • It fixes atmospheric nitrogen to the level of 20-40 kgs per hectare and thereby helps to reduce the amount of synthetic fertilizer usage.
  • Helps to increase the crop yield.
  • It improves the plant vigor and health.
  • Help to improve the soil health.
