Abstract : Slow- and controlled-release fertilizers (S-CRF) were proposed as a compound to improve the nutrient use efficiency of plants and hence considered a response to address the problems due to the growth of the world's population and water shortage of bell pepper. Thus, this study adapted a physical barrier to help regulate a gradual release of fertilizer from the soil use of plastic bottle barriers. It aimed to evaluate the potential investigation of the effects of the slow-release fertilizers – plastic bottles of barriers (SRF-PB) and CRF on the growth and fruit yield. The experiment was laid out in RCBD with treatment (7) and replications (3). It was assigned as T0 - control, T1 - conventional application of fertilizer, T2 - commercial CRF; and T3 - 25%, T4 - 50%, T5 - 75%, and T6 - 100% at the holed portion in SRF-PB. The results revealed that utilizing had significantly (p < 0.05) increased the plant height on T1, width of leaves and length of leaves on T1; fresh dried on T1 and oven-dried on T2; early-to-flowering on T2 and fruiting set between T1 and T2; and root characterizing were weight root, length root, and roots density with T1 and T2; T2; and T1 and T6, respectively, the growth period of bell pepper. Furthermore, the specific higher root density of T6 and T2's nutrient utilization efficiency has improved, resulting in a significant (p < 0.05) due to the rise in T2 and T6 high yield of harvested fruits. In conclusion, SRF-PB of T6 could be an alternative means for commercial T2 in terms of achieving better productivity of bell pepper.
