Soil-dwelling bacteria are important components of soil health status as they play crucial roles in recycling and transforming nutrients so that they are available to plants . A diverse group of soil bacteria known as plant growth promoting rhizobacteria(PGPR) isable to inhabit the area close to plant roots and provide beneficial effects on the growth of the plant. Plant growth promotion by PGPR involves direct mechanisms which improve nutrient uptake and regulation of phytohormones. PGPR facilitate nitrogen, phosphorus and iron uptake via N2-fix- ation, inorganic phosphate solubilization and production of iron chelators known as siderophores, respectively PGPR are able to modulate phytohormones by synthesizing the auxin, indole-3-acetic acid(IAA) and producing 1-aminocyclopropane-1-carboxylate(ACC) deaminase which decreases ethylene levels. Indirect mechanisms of plant growth promotion mainly involve biocontrol and reducing inhibitory e on plant growth. Biocontrol by PGPR is achieved by competition for nutrients and sites, reduction of virulence factors, production of antifungal compounds and induced systemic resistance. The beneficial features that bacteria exert on plants, while the two are in association can be harnessed by isolating the relevant bacteria and reintroducing them into crop agri cultural environments at favourable conditions, i.e at increased population numbers or in a conducive substrate The majority of Namibians based in the North and North Eastern regions depend on subsistence agriculture for their livelihood.
