Fertilizer is considered to be one of the important factors in increasing shallot production. However, this must be followed by proper fertilization management to meet the nutrient requirements of the plant. This research was conducted with the aim of dertermining the correct dosage of NPK 16:16:16 based on ammonium nitrate in shallot plants. The assessment was carried out in October-December 2018. The research was carried out at one of the centers of shallot development, specificallly in Batu Rampung Hamlet, Tanete Village, Angeraja Sub-District, Enrekang Regency, South Sulawesi. A randomized block design (RBD) was used in this research, accompanied by three replications and eight treatments: P1 = NPK Nitrate 16-16-16 450 kg/ha + Urea 150 kg/ha + ZA 300 kg/ha; P2 = NPK Nitrate 16-16-16 400 kg/ha + Urea 150 kg/ha + ZA 300 kg/ha; P3 = NPK Nitrate 16-16-16 350 kg/ha + Urea 150 kg/ha + ZA 300 kg/ha; P4 = NPK Nitrate 16-16-16 900 kg/ha; P5 = NPK Nitrate 16-16-16 800 kg/ha; P6 = NPK Nitrate 16-16-16 700 kg/ha; P7 = Urea 200 kg/ha + ZA 400 kg/ha + KCL 100 kg/ha; P8 = NPK Phonska 645 kg/ha + Urea 645 kg/ha + SP36 645 kg/ha. The results showed that NPK Nitrate Fertilization 16:16:16 at a dose of 700- 900 kg/ha indicated a fairly high growth and production (14.5-16.3 t/ha). The results obtained were not significantly different from the high-dose fertilization used by farmers (17.2 t/ha), and higher than the single dose based on the recommendation (12.8 t/ha).
