The rhizosphere of Momordica charantia (Bitter gourd) has a significant effect on the aerobic bacteria, anaerobic bacteria and actinomycetes population compared to the respective barren soil. Rhizospheric soils (0–25 cm depth) along the roots were processed at surface (0-1 cm) and also at 5 cm interval in the spring season. Bacterial population significantly differed in each transect with a maximum at 1–5 cm depth, and decreased with the increase in the root length. Rhizosheric region (20–25 cm) exhibited maximum R/S ratio (rhizospheric effect). Microbial population differed significantly season wise in rhizosphere and barren soil. The maximal number of anaerobic bacteria was during rainy season. Rhizosphere was maximally colonized by bacteria at the flowering and fruiting stage. Root border cells released in highest number in the 5 cm root length during seedling growth. | Microbial diversity in the rhizosphere of Momordica charantia L. Bitter gourd
