摘要

The samples used for this study were obtained from different rhizosphere garden soil sources. This include sweet potato rhizosphere soil (SPRS), plantain rhizosphere soil (PLRS), pineapple rhizosphere soil (PARS), pepper rhizosphere soil (PEPRS) and the control soil sample source (CSSS). The bacterial population determined by a pour plate technique showed a range of 4 x10~(-5) cfu/mL in control soil sample source (CSSS), to 29 x10~(-5 )cfu/mL in sweet potato rhizosphere soil (SPRS). The bacterial isolates include Aerobacter spp., Bacillus cereus, Bacillus subtilis, Bacillus spp., Escherichia spp., Lactobacillus spp., Micrococcus spp., Pseudomonas aeruginosa , Pseudomonas spp., Rhizobium spp., Staphylococcus spp., while the fungi isolates were Aspergillus, Fusarium, Candida, Epidermophyton, Geotrichum, Verticillum, Trichophyton, Tubercularia, Beauveria, Cladosporium, Chaetomium, Botryotrichum and Rhizopus. Bacillus spp. constituting 53.34% and Pseudomonas spp. constituting 13.33% of the total isolates are the most dominant microorganism in soil sources studied. The moisture content for the samples range from 6.67% in PEPRS to 19.33% in PLRS. Some physiological studies show the range of pH from pH 4.92 in CSSS to pH 8.01 in PLRS sample sources. The soil pH values obtained in this study were near neutral ranges, which favour microbial growth. Various species of fungi were encountered in soil sources including the harmful ones. Hence, fungicides can be applied occasionally on these soils to reduce the fungi load in these areas when necessary.Data obtained in this study is valuable to monitor and protect the environment including agriculture products for sustainable economic development.
