Abstract: Tujuan penelitian ini untuk mengetahui dosis terbaik pupuk fosfat terhadap pertumbuhan dan produksi tanaman kacang kedelai (Glycine Max L.) pada tanah ultisol. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok secara Non Faktorial yang terdiri dari satu faktor perlakuan, yaitu Pupuk Fosfat (notasi P) terdiri dari 4 taraf perlakuan,yakni PO : kontrol, P1 : 0,19 g/tan, P2 : 0,38 gitan, dan P3 : 57 g/tan. Pengamatan dilakukan terhadap tinggi tanaman (cm), jumlah cabang, umur berbunga (hari), jumlah polong per sampel, jumlah polong per plot, berat biji per sampel (2), berat biji per plot (g) dan berat 100 biji kering (9). Hasil penelitian menunjukkan bahwa pemberian Pemberian pupuk fosfat di tanah ultisol berpengaruh sangat nyata terhadap jumlah polong per tanaman sampel, jumlah polong per plot, berat biji per tanaman sampel, berat biji per plot dan berat 100 biji kering kacang kedelai (Glycine max L.). Namun, berpengaruh tidak nyata terhadap tinggi tanaman, jumlah cabang dan umur berbunga. Dengan dosis terbaik pemberian TSP yaitu perlakuan P3 yaitu 0,57 g/polibag. The aim of this research was to determine the best dose of phosphate fertilizer for the growth and production of soybean plants (Glycine Max L.) on ultisol soil. This research was conducted using a non-factorial randomized block design consisting of one treatment factor, namely Phosphate Fertilizer (P notation) consisting of 4 treatment levels, namely PO: control, P1: 0.19 g/tan, P2: 0.38 gitan, and P3: 57 g/tan. Observations were made on plant height (cm), number of branches, flowering age (days), number of pods per sample, number of pods per plot, seed weight per sample (2), seed weight per plot (g) and weight of 100 dry seeds (9 ). The results of the research showed that the application of phosphate fertilizer in ultisol soil had a very significant effect on the number of pods per sample plant, the number of pods per plot, the weight of seeds per sample plant, the weight of seeds per plot and the weight of 100 dry seeds of soybeans (Glycine max L.). However, it has no significant effect on plant height, number of branches and flowering time. The best dose for administering TSP is P3 treatment, namely 0.57 g/polybag.
