Abstract :
Soil acidification is a critical constraint to sustainable crop production, particularly in regions with intensive
cultivation practices. Liming is a widely adopted strategy to ameliorate soil acidity, improve nutrient availability, and
enhance microbial diversity. The present study aimed to isolate and characterize bacterial strains from cultivated soils
collected before and after liming, and to evaluate their effects on seed germination and seedling growth of selected crop
plants. Several bacterial isolates were obtained and screened for their plant growth-promoting traits, including phosphate
solubilization, indole-3-acetic acid (IAA) production, and antagonistic activity against soil-borne pathogens. Seeds treated
with these isolates demonstrated significantly higher germination rates, enhanced root and shoot elongation, and improved
vigor index compared to untreated controls. The findings suggest that liming not only alters the physicochemical properties
of soil but also fosters beneficial microbial communities that can act as bioinoculants to support sustainable agriculture.
This study highlights the potential of lime-influenced soil bacteria as eco-friendly alternatives to chemical inputs for
promoting crop establishment and productivity.
