This research aims to determine the real interaction between bokashi dose treatment and spacing models on the growth and yield of paddy plants. The study used a 3 x 3 factorial with 3 replications. The first factor was the spacing model which consists of 3 levels, namely J1 = tile spacing model (20 x 20 cm), J2 = Jajar Legowo 4:1 (20 cm x 40 cm x 10 cm), and J3 = Jajar Legowo 2:1 (20 cm x 40 cm x 10 cm). The second factor was the dosage of bokashi fertilizer which consists of 3 levels, namely P1 = 5 tonnes per hectare, P2 = 10 tonnes per hectare, and P3 = 15 tonnes per hectare. The research discovered that there was an interaction effect on plants aged 45 days after planting as well as an increase in yield in the form of an increase in grain weight per plant clump. Model treatment also had a significant effect on plant height at the age of 15 and 30 days after planting. In addition, there were also changes in the number of tillers, productive tillers, seeds per panicle, panicle length, and grain weight per plot for all observed ages. The 4:1 legowo row model treatment resulted in the best growth and production of paddy fields, while the highest production was produced by the legowo row 2:1 treatment. Bokashi dosage treatment was 15 tons per hectare.Isi artikel ini bertujuan mengetahui adanya interaksi yang nyata antara perlakuan dosis bokasi dan model jarak tanam terhadap pertumbuhan dan hasil tanaman padi. Penelitian menggunakan rancangan acak kelompok (RAK) faktorial 3 x 3 dengan 3 kali ulangan. Faktor pertama adalah model jarak tanam yang terdiri dari 3 taraf, yaitu J1 = model jarak tegel (20 x 20 cm), J2 = Jajar Legowo 4 :1 (20 cm x 40 cm x 10 cm), dan J3 = Jajar Legowo 2 : 1 (20 cm x 40 cm x 10 cm). Faktor kedua adalah dosis pupuk bokashi yang terdiri dari 3 taraf yaitu P1 = 5 ton/ha, P2 = 10 ton/ha, dan P3 = 15 ton/ha. Riset yang dilakukan membuktikan bahwa adanya pengaruh interaksi pada tanaman umur 45 hari serta peningkatan hasil panen berupa berat gabah per rumpun yang mengalami kenaikan. Perlakuan model juga memiliki pengaruh nyata terhadap tinggi tanaman pada usia 15 dan 30 hari sejak masa tanam. Selain itu juga adanya perubahan pada jumlah anakan, anakan produktif, biji per malai, panjang malai, dan berat gabah per petak semua umur pengamatan. Perlakuan model jajar legowo 4 : 1 menghasilkan pertumbuhan dan produksi padi sawah pertanaman paling baik, sedangkan produksi paling tinggi dihasilkan oleh perlakuan jajar legowo 2 : 1. Perlakuan dosis bokasi 15 ton/ha
