Abstract

The soil samples were collected from the west to east side of the region. Most of the collected soil samples were highly saline, but salinity levels decreased as we headed east. The EC values ranged from 4014 t0 26.16. The viable counts of R. leguminosarum bv. viceae, R. leguminosarum bv. trifolii and Azotobacter varied through different sites,they ranged from log to log 5.84; log 2.39 to 5.84; log 2.23 to 4.26, respectively and the variations between readings were ,sometimes, significant. But, there were no significant correlations between the estimated bacterial types and soil salinity. Total bacterial readings, however, showed high values, but, lowered in soil samples collected from the west sites.These bacterial counts were decreased as we headed east. They ranged from log 7.36 to log 9.46. However, there was no significant correlation between bacterial counts and soil salinity.
