The objective of this study was to assess application effects of slurry composting bio-filtration liquid fertilizer (SCB) on red pepper (Capsicum annuum L.) yield and nitrate leaching. A lysimeter experiment was conducted to evaluate the impact on the nitrate leaching and red pepper yield No N fertilizer, four application N rates of SCB (0, 103, 155, and 206 kg ha<SUP>-1</SUP>) and a control treatment of chemical fertilizer (103 kg ha<SUP>-1</SUP>). SCB were used as a basal fertilization and three top dressing doses of urea at the 35<SUP>th</SUP>, 60<SUP>th</SUP>, and 80<SUP>th</SUP> day after transplanting were applied. There was no significant different in red pepper yield among the SCB 100%, 150%, 200%, and CF 100%, though which was decreased in the No N fertilizer in 2008 and the No N fertilizer and the SCB 0% in 2009. The Increase of SCB liquid fertilizer application rates intensified the leached nitrate concentration and nitrate load. The leached N load in the SCB 100% was 193 kg ha<SUP>-1</SUP> in 2008 and 138 kg ha<SUP>-1</SUP> in 2009. However the leached N load in the SCB 150% and 200% were 236 and 274 kg ha<SUP>-1</SUP> in 2008 and 173 and 216kg ha<SUP>-1</SUP> in 2009, respectively which were higher 43 and 80 kg ha<SUP>-1</SUP> in 2008 and 38 and 78 kg ha<SUP>-1</SUP> compared to that in the SCB 100%. Meanwhile, the SCB 100% did not increased the nitrate leaching compared with the CF 100% though the leached N load was higher in the SCB 100% in early season of red pepper cultivation. Therefore, the application of SCB rates equivalent to N recommendation for red pepper was evaluated to substitute a basal nitrogen fertilizer because there was no difference in nitrate leaching and red pepper compared with the chemical fertilizer.
