Abstract
The increasing cost of inorganic fertilizers
and their associated environmental impacts have necessitated the search for
sustainable alternatives for crop production. This study investigated the
potential of indigenous soil microorganisms for biofertilizer production and
their application in improving soil fertility and maize (Zea mays L.)
growth in Bauchi State, Nigeria. Rhizospheric soil samples were collected from
soybean fields and subjected to microbiological isolation, biochemical
characterization, and molecular identification using 16S rRNA gene sequencing.
The isolates were screened for phosphate-solubilizing and nitrogen-fixing
abilities before being utilized for biofertilizer production. Molecular
analysis revealed that the predominant isolate showed 99.93% similarity with
members of the genus Comamonas, particularly Comamonas testosterone.
The formulated biofertilizer was evaluated in a pot experiment alongside NPK
fertilizer and an untreated control. Results indicated that biofertilizer
application enhanced soil nutrient status and improved maize growth performance
compared with the control treatment. Biofertilizer-treated plants consistently
produced higher leaf numbers and greater plant height than plants receiving NPK
fertilizer or no fertilizer treatment. The findings demonstrate that indigenous
microorganisms possess considerable potential for sustainable biofertilizer
production and could contribute significantly to reducing dependence on
synthetic fertilizers in Nigeria.
