This study was conducted to evaluate the effect of application levels of inorganic fertilizer (IF) with corn waste biochar (BC) for corn cultivation in an upland field (34° 94ʹ 24ʺ N, 127° 56ʹ 55ʺ E). The IF (N-P-K 14.5-3.0-6.0 kg 10a<SUP>-1</SUP>) was applied at levels of 25%, 50%, 75%, and 100% of standard amount with BC (BC+IF25, BC+IF50, BC+IF75, and BC+IF100, respectively), and Cn (control), BC and IF treatments were added in this study. The BC was application of 500 kg 10a<SUP>-1</SUP> at 20 days before corn sowing. The mean biomass productivity of corn plants, when grown under Cn, BC, IF, BC+IF25, BC+IF50, BC+75, and BC+IF100 treatment conditions, were 1.82, 2.21, 2.74, 2.40, 3.12, 3.73, and 4.05 kg m<SUP>-2</SUP>, respectively. The corn length was 14.6-18.3 cm ear<SUP>-1</SUP> in all treatments, and the total weight of corn increased in the order BC+IF100 ≒ BC+IF75 > BC+IF50 > IF > BC ≒ BC+IF25 > Cn treatments. The corn productivity was highest (3.97 kg m<SUP>-2</SUP>) in the BC+IF100 treatment. The corn grain yields in BC+IF50, BC+IF75, and BC+IF100 treatments increased by 145, 129, and 103% respectively, over that in the IF treatment. Based on our results, the minimum IF application level using biochar for corn cultivation was N of 7.25 kg 10a<SUP>-1</SUP>, P of 1.5 kg 10a<SUP>-1</SUP>, and K of 3.0 kg 10a<SUP>-1</SUP>, respectively. Therefore, proper application of inorganic fertilizer with biochar is effective at improving corn cultivation and can benefit the soil environment.
