Biochar created from bat manure (guano) is a way to produce a value added soil amendment that is less expensive and rich in macro and micronutrients, however, limited published studies about its effects on nutrient availability to plants are available Hence, a pot experiment was conducted at the experimental site of the Department of Agriculture and Related Programs, Northwest Samar State University, San Jorge Campus, San Jorge, Samar from June 2017 to February 2018. The study aimed to determine the effects of guano char (GC) on the growth and yield of sweet corn and properties of degraded upland soils, and to determine the optimum rate of GC in luencing growth and yield of sweet corn. There were ive treatments used: (T1 - 0g GC kg-1 soil; T2- 75 kg-1 soil, T3 150g GC kg-1 soil, T4-300g GC kg-1 soil and T5-600g GC 15 kg-1 soil) with three replications and arranged in Randomized Complete Block Design (RCBD). Transplanting of sweet corn was done after 10 days of soil incubation. Sweet corn were harvested 65 days after planting for soil and tissue analysis and data gathered were subjected to statistical analysis using SPSS version IZ Results revealed that addition of increasing rates of guano char resulted in consistent increase on weekly plant height (cm) and fruit yield (kg) sweet corn, Statistically, results indicated that 75 g to 150g of GC 15 kg-1soil found as optimum rate enhancing growth and yield of sweet corn. On the other hand, addition of guano char significantly increases the soil pHH20, % OM, total N, extractable P and exchangeable K after harvest. Likewise, plant tissue N and P concentration were also increased.
