Increasing the productivity of peatlands can be done by applying the right fertilization system. The purpose of this study was to determine the appropriate dose of NPK fertilization in intercropping red chili and shallots on peat soil. This research was conducted at the Laboratory and Experimental Garden of the Faculty of Agriculture, Indragiri Islamic University. The study took place from August to December 2020. The study was carried out using a Completely Randomized Design (CRD) with 3 replications, N2 (500 kg/ha), N3 (750 kg/ha) in red chilies and shallots. The results showed that treatment with a dose of 500 kg/ha of NPK fertilizer in an intercropping system of chili with shallots on peat soil gave the best growth and yield of shallots. Treatment dose of 250 kg/ha NPK fertilizer gave the best red chili fruit production.   Peningkatan produktivitas lahan gambut dapat dilakukan dengan menerapkan sistem pemupukan yang tepat. Tujuan penelitian ini adalah untuk menentukan dosis pemupukan NPK yang tepat pada tumpangsari cabai merah dan bawang merah di tanah gambut. Penelitian ini dilaksanakan di Laboraturium dan Kebun Percobaan Fakultas Pertanian, Universitas Islam Indragiri. Penelitian berlangsung daribulan Agustus hingga Desember 2020. Penelitian dilaksanakan dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 3 ulangan.Perlakuan dalam penelitian ini dosis pupuk NPK 16:16:16 yaitu N0 (0 kg/ha), N1 (250 kg/ha), N2 (500 kg/ha), N3 (750 kg/ha) pada cabai merah dan bawang merah. Hasil penelitian menunjukkan bahwa perlakuan dosis pupuk NPK 500 kg/ha dalam system tumpangsari cabai dengan bawang merah di tanah gambut memberikan pertumbuhan dan hasil tanaman bawang merah terbaik. Perlakuan dosis pupuk NPK 250 kg/ha mememberikan produksi buah tanaman cabai merah terbaik.
