In the current study cyanobacterial strains isolated from
rice fields were evaluated as biofertilizers. They were
tested for different plant growth promoting traits such as
phosphate solubilization, nitrogen fixation and, hydrogen
cyanide and auxin production. The two selected
cyanobacterial strains were identified as phormidium
SM-14 and SM-15. Both strains were able to solubilize
phosphate, fix atmospheric nitrogen and produce hydrogen
cyanide. Cyanobacteria produced variable amount of auxin in
the presence of different concentrations of L-Tryptophan.
Cyanobacterial strains used as biofertilizers have
tremendous potential to enhance growth of Triticum
aestivum var. Uqab 2000 in control conditions.
Key words:
