Which plant is used as biofertilizer?

So the correct answer is ‘Nostoc’.

Is azotobacter a biofertilizer?

Owing to its ability to improve plant health through nitrogen fixation, growth hormone production, phosphate solubilization, plant disease management and reclamation of better soil health, Azotobacter is one of the best options to be used as biofertilizer for eco-friendly and sustainable crop production.

What is Rhizobium biofertilizer?

It is a biofertilizer that contains symbiotic Rhizobium bacteria which is the most important nitrogen-fixing organism. These organisms have the ability to drive atmospheric Nitrogen and provide it to plants.

What is Azolla biofertilizer?

Azolla is water fern which is also used as a biofertilizer. There are around 80,000 symbiotic cyanobacteria present on its leaves. Symbiotic cyanobacteria Anabaena Azollae is responsible for nitrogen-fixation which increases the fertility of the soil and in turn enhances the yield.

What is Azotobacter biofertilizer?

It is a biofertilizer that contains non-symbiotic Azotobacter bacteria which has the ability to fix atmospheric Nitrogen. It is recommended for non-leguminous crops like Paddy, Wheat, Millets, Cotton, Tomato, Cabbage, Mustard, Safflower, Sunflower, etc..
