Fertilization isadding nutrients to the soil the addition of nutrients including into the soil to support the growth and development of shallot plants. When applied,compound NPK fertilizersare more practical than single fertilizers the use of compound NPK fertilizers is more practical than single fertilizers. This study aims to examine the effect of compound NPK fertilizer on the yield of shallots in Pabuaran District, Cirebon Regency. The study was carried out in irrigated rice fields, Pabuaran Lor Village, Pabuaran District, Cirebon Regency from June to September 2019. The study used a Randomized Completely Block Design (RCBD) with nine treatments and three replications. Each treatment consisted of a rate of NPK fertilizer (NPK 16-16-16 and NPK 15-9-20) and the time of application. Data were analyzed by means of variance with Duncan Multiple Range Test test at 95% confidence level. The results showed that the highest yield of shallots per hectare was obtained in the treatment of NPK 16-16-16 fertilizer at a rate of 650 kg ha-1(350 kg ha-1aged 0 DAP and 300 kg ha-1aged 15 DAP) and NPK 15 -9-20 with a rate of 300 kg ha-1(150 kg ha-1at 15 DAP and 150 kg ha-1at 35 DAP) which was 22.60 tons ha-1, while the highest bulb tuber weight per plant was produced by the treatment of NPK 16-16-16 at a rate of 650 kg ha-1(250kg ha-1at 10 DAP, 200 kg ha-1at 15 DAP, and 200 kg ha-1at 35 DAP) and NPK 15-9-20 at a rate 200 kg ha-1(100 kg ha-1at 25 DAP and 100 kg ha-1at 35 DAP).The results showed that the best shallot yields were obtained in the NPK 16-16-16 fertilizer treatment with a dose of 650 kg ha-1(250 kg ha-1at 10 HST, 200 kg ha-1at 15 HST, and 200 kg ha-135 HST) and NPK 15-9-20 at a dose of 200 kg ha-1(100 kg ha-125 HST and 100 kg ha-135 HST) with a yield of tuber weight per plant of 68.67 g
