Cyanobacteria make a major contribution to the fertility of soil. It has been suggested that cyanobacteria assist higher plant growth by supplying growth substances. There are numerous works about
effect of cyanobacteria in paddy soils and rice growth in the world but very little research has been carried out in Afghanistan. In this research, cyanobacteria Anabaena sp were isolated from paddy soils of
Baghlan Province of Afghanistan. The isolated cyanobacteria Anabaena sp was used as inoculums on
three common varieties of Afghanistan’s rice separately for two hours. After 10 days the result revealed
that inoculation of rice seeds by cyanobacteria extracts can enhance seed germination, plant height and
length of root in all treated seeds in comparing seeds control by water. In the next stage, seeds under
experiment separately inoculated by cyanobacteria extracts and cultivated in nonorganic silt soil as well
as treated by cyanobacteria extracts. After 12 days the morphological view showed differences in shoot
height of treated plants in comparing to plant controlled by water. Therefore cyanbacteria Anabaena sp.
recommended as an effective biofertilizer in paddy fields of Afghanistan.
