Fertilizers as a source of plant nutrition can be supplied in the form of single or compound fertilizers. Ammonium phosphate fertilizer is a compound fertilizer containing the main nutrients nitrogen and phosphate, also sulfur as an additional nutrient in some of its products. This research which aimed to determine the effectiveness of Ammonium phosphate fertilizer on the growth and yield of maize was carried out in Pasar VI Village, Sei Bingai Sub-district, Langkat District, North Sumatra, from June to November 2020. The research was arranged in a non-factorial randomized block design with 7 treatments which were repeated 4 times. The treatments were Control, Standard (200 kg Urea+200 kg SP-36+100 kg KCl), AP ½ (100 kg Ammonium phosphate+100 kg Urea+50 kg SP-36+100 kg KCl), AP 1 (200 kg Ammonium phosphate+100 kg Urea+50 kg SP-36+100 kg KCl), AP 1¼ (250 kg Ammonium phosphate+100 kg Urea+50 kg SP36+100 kg KCl), AP 1½ (300 kg Ammonium phosphate+100 kg Urea+50 kg SP-36+100 kg KCl) and AP 1 ¾ (350 kg Ammonium phosphate+100 kg Urea+50 kg SP-36+100 kg KCl). The results showed that the application of Ammonium phosphate fertilizer had a significant effect on the height and yield of maize. The maximum height and maize yield were found in AP 1¾ treatment with average values of 213.1 cm and 8.2 tons Ha−1, respectively. The highest relative agronomic effectiveness (RAE) value was also found in treatment AP 1¾, while the R/C ratio for AP ½ and AP 1½ treatment gave the same value and was higher than the other treatments.
