Sweet pepper consumption in the Philippines is low due to nutrient-deficient soils. Since chicken manure and coco coir were widely used in the country as soil enhancers, the study determined the appropriate combination rate of chicken manure char (CMC) and coco coir char (CCC) application in enhancing the growth and yield of sweet pepper and evaluated the chemical properties of acidic grassland soil. A pot experiment was conducted with bell pepper as a test crop. The soil used was collected randomly from a depth of 0-20 cm at the grassland area of NwSSU, San Jorge Campus, San Jorge Samar. Replicated thrice, the treatments used were T1= Control, T2= 100% CMC 10 kg-1 soil, T3= 100% CCC 10 kg-1 soil, T4–75% CMC+ 25% g CCC10 kg-1 soil, T5–50% CMC+ 50% CCC10 kg-1 soil, T6-25% PLC+ 300 g CCC10 kg-1 soil. Charred chicken manure and coco coir were produced using a modified top lift updraft double barrel method. CMC and CCC mixture was incubated with soil for 14 days before transplanting. Sweet pepper was harvested after 90-95 days from transplanting. Plant tissue and soil samples were chemically analyzed. Results revealed that CMC and CCC addition particularly enhanced the plant height of sweet pepper; lessen their number of days from transplanting to flowering, fruiting and harvesting; and marketable yield. Moreover, CMC and CCC mixture addition significantly increased the pH,% OM, total N, extractable P, and exchangeable K of acidic grassland soil.
