: Permanently frequent utilization of fertilizer posed problems in soil fertility that hinder farmers’ crop production due to excessive soil erosion and rapid leaching of essential nutrients. It aimed to evaluate the effect of SRF-PB (Slow releases fertilize- Plastic bottles) on the chemical properties of soil and the yield potential of green bell pepper. It was assigned as chemical soil samples were organic matter (OM), pH, nitrogen (N), phosphorus (P2O5), and potassium (K2O). The experiment was laid out in RCBD with seven treatments and three replications, respectively. The results were collected T0-control, T1-water-soluble fertilizer application (WSF), T2-commercial controlled-release fertilizers (CRF); and SRF-PB of 25%, 50%, 75%, and 100% with T3-T6 holed portion in the treatments, respectively. The soil pH of treatments applied with control, commercial CRF, and SRF-PB technology ranges from medium acidic (T0 and T2 -T6) and slightly acidic (T1). OM content, on the other hand, was found to be low among the treatments (T0-T4 and T6) and desired with T5 of the percentage treatments. The N level suggests that all sites reach a relatively low range. The phosphorus was high in T1-T5, and sufficient in T0 and T6 observed treatments. The potassium was acceptable in decreasing T0 and T2, slowly increasing at high T6, and excessive in swiftly increasing T1 and T3-T5. In contrast, the significantly (p <0.05) highest yielding findings revealed that using T2 increased fertilizer efficiency, with T6 having a higher root density and a higher harvest yield. In terms of increasing green bell pepper yield, T6 might be a viable alternative to commercial T2..
