<![CDATA[The study aimed to determine Arbuscular Mycorrhizal Fungi and rice straw and their interactions independently in increasing the growth and yield of black rice in rain-fed rice fields. The experiment was conducted in Tebas District, Sambas Regency, from July to December 2022. The experiment was arranged using a split-plot and randomized block design pattern. The main plot was AMF treatment (without AMF and AMF administration), and the subplots were rice straw dose (tons/ha) (0, 5, 10, 15). The experiment was repeated 3 times and consisted of 16 observed plant samples. The results showed that AMF and rice straw interaction affected root volume and grain weight per plot. AMF independently affects plant height, the number of productive tillers, and the percentage of filled grain. The applied rice straw plays a role in influencing plant height, the number of productive tillers, and the rate of filled grain. Keywords: arbuscular mycorrhizal fungi, rice straw, black rice, ricefield INTISARITujuan penelitian yaitu untuk mengkaji peran FMA dan jerami padi serta interaksi keduanya masing-masing secara mandiri dalam meningkatkan pertumbuhan dan hasil padi hitam di sawah tadah hujan. Percobaan dilaksanakan Kecamatan Tebas, Kabupaten Sambas pada bulan Juli sampai Desember 2022. Percobaan disusun menggunakan rancangan split plot dengan pola rancangan acak kelompok. Petak utama yaitu perlakuan FMA (tanpa FMA dan pemberian FMA), anak petak yaitu dosis jerami padi (ton/ha) (0, 5, 10, 15). Percobaan diulang sebanyak 3 kali dan terdiri atas 16 sampel tanaman amatan. Hasil penelitian diperoleh bahwa interaksi FMA dan jerami padi berpengaruh terhadap volume akar dan berat gabah per petak. FMA secara mandiri berpengaruh terhadap tinggi tanaman, jumlah anakan produktif dan persentase gabah isi. Jerami padi yang diaplikasikan berperan dalam mempengaruhi tinggi tanaman, jumlah anakan produktif dan persentase gabah isi. Kata kunci: fungi mikoriza arbuskula, jerami padi, padi hitam, sawah ]]>
