Morphological and Biochemical Characterization of Azotobacter Isolated From Different Rhizospheric Soils of Kathmandu Valley
Biological nitrogen fixation by free-living diazotrophic bacteria, particularly Azotobacter spp., offers a sustainable way to replenish soil nitrogen. This study aimed to isolate and characterize Azotobacter from rhizospheric soils of ten crop species collected across Kathmandu Valley, and examine the influence of soil...
