The application in agricultural fields of pig slurry composting biofiltraton amending smell and nutrient unevenness, it is important for the appropriate nitrogen nutrient management to promote the availability of the crops and to minimize the risk of adversely environmental effects. The objective of this study was to determine the application rates of the preplant pig slurry composting biofiltration for red pepper (Capsicum annuum L.) by considering the yield response and the fruit quality such as sugar, capsaicinoid content. Red peppers were grown on plastic film ground under five different pig slurry (PS) application rates and mineral fertilizer (MF 100%) as a control. The effects of a single application of five different doses of PS: PS 0% (no kg N ha-1), PS 50% (51.5 kg N ha-1), PS 75% (77.3 kg N ha-1), PS 100% (103 kg N ha-1) and PS 125% (129 kg N ha-1) were compared with the recommended mineral treatment (103 kg N ha-1) in the pre-planting. The sidedressing N application (87 kg N ha-1) was applied to the mineral fertilizer in all treatments. Red peppers were harvested at the mature red stage through five times from 72 days after transplanting (DAT) to 133 DAT. The results indicated that the yield of red pepper was increased with the increase of the N application rates from PS 0% to PS 100%. The highest yield was obtained in PS 100% by 20,843 kg ha-1, although there were no significant differences in yield among PS 100, PS 125% and MF 100%. In addition, The contents of soluble sugar and capsaicinoids were not significantly different in all treatments. Accordingly, fertilization recommendations of red pepper to substitute PS for the mineral fertilizer were considered to PS 100%.
