This study was carried out to determine the effects of selected beneficial bacterial isolates with N fertilizer application on yield and nutrient content of sweet potato under field condition. A factorial experiment with two factors (Plant growthpromoting rhizobacteria inoculation and N fertilizer) was positioned with three replications in a Randomized Complete Block Design (RCBD). Three stages of N fertilizer (0, 33, and 100 kg N ha-1) and five strains of bacteria (Bacillus sphaericus UPMB10, Erwinia sp. UPMSP10, Klebsiella sp. UPMSP9, Azospirillum brasilense SP7 and Uninoculated control) were used for treatments. Plants were grown on sandy clay soil at the Universiti Putra Malaysia experimental plot. The effect of bacterial population in the soil at different phases of plant growth was significantly stimulated by bacterial inoculation and N fertilization. The soil inoculated with Klebsiella sp. applied with 33 kg N ha-1 showed highest population of 2.63X107 CFU g (dry wt.)-1 soil. However, after the 2nd and 3rd month of inoculation, the number of bacteria in soil dropped. The results of inoculated plants showed significant differences in sweet potato yield, N, P, K, Ca and Mg contents of storage root compared to control. After the field experiment, it was found that plants inoculated with Klebsiella sp. applied with 33 kg N ha-1 showed the highest storage root yield. Substantial relations among PGPR inoculation and N fertilization was detected on nutrient content of sweet potato storage roots. Klebsiella and application of 33kg N ha-1 demonstrated the highest N, P, K, Ca, Mg content of storage roots. These results recommended that Klebsiella sp. can be used as biofertilizer of sweet potato for decreasing the rates of N fertilizers and giving a stage forward for sustainable agriculture.
