Abstract
Isolation and purification of cyanobacteria from kafr El-Sheikh soil samples revealed that, two isolates (Anabaena cylindrica and Nostoc clacicola) were acquired as bacterial free cyanobacteria and nitrogen fixed. These cynobacteria isolates were produced auxin (Indole-3-acetic acid), gibberellins (Gibberellic acid) and cytokinin (Zeatin). Therefore, when inoculation with Anabaena cylindrica, Nostoc clacicola and their mixture were significantly increased the plant height, number of spikes/m2, 1000-grain weight, grain yield, straw yield protein content% on wheat crop and total counts of cyanobacteria in soil.
