Abstract

Cyanobacteria (BGA) are one of the most important microorganism in paddy fields. They plays an important role in the enhancement of soil fertility along with yield of rice. It is having unique feature of nitrogen fixation, which leads to enhancement of productivity. In the present study we have selected few areas close to Allahabad like soraon, mauaima etc. Our sample collection area is only paddy fields and would like to collect different genera of blue green algae, along with this we like to culture these cyanobacteria in lab conditions. We have cultured them and taken pictures of blue green algae and differentiate them on the basis of genera. In the present study we concluded few most important genera with different species found in abundance in paddy fields.
