      Abstract
      Padi (Oryza sativa L.) merupakan komoditas yang dibutuhkan di Indonesia dikarenakan sebagai sumber energi dan karbohidrat. Seiring bertambahnya penduduk Indonesia maka bertambah juga kebutuhan akan beras sebagai unsur makanan pokok utama. Namun, produksi di Indonesia masih belum mencukupi kebutuhan tersebut. Faktor yang mempengaruhi produksi padi antara lain yaitu varietas unggul, pemupukan dengan tepat, pengendalian hama dan penyakit, pengolahan tanah yang baik, dan sistem irigasi yang baik. Pada faktor tersebut, beberapa diimplementasikan ke penelitian ini yang bertujuan untuk mengetahui pengaruh dosis pupuk anorganik dengan penambahan pupuk hayati terhadap pertumbuhan dan produksi tanaman padi. Penelitian dilaksanakan di Kebun Percobaan IPB Sawah Baru pada bulan November 2023 hingga Maret 2024. Rancangan percobaan yang digunakan adalah Rancangan Kelompok Lengkap Teracak (RKLT) Split-Plot memiliki dua faktor antara lain yaitu pupuk anorganik sebagai petak utama dengan dua taraf yaitu 100% dosis rekomendasi (N1) dan 50% dosis rekomendasi (N2). Faktor kedua yaitu pupuk hayati sebagai petak anakan dengan lima taraf yaitu tanpa pupuk hayati (P0), pupuk hayati jenis 1 (P1), pupuk hayati jenis 2 (P2), pupuk hayati jenis 3 (P3), dan pupuk hayati jenis 4 (P4). Terdapat pengaruh yang nyata terhadap komponen pertumbuhan dan produksi tanaman padi yakni jumlah anakan vegetatif, tinggi tanaman, umur berbunga, jumlah gabah hampa, jumlah gabah total, kerapatan gabah, dan bobot ubinan.
       
      Rice (Oryza sativa L.) is a commodity that is needed in Indonesia because it is a source of energy and carbohydrates. As the population of Indonesia increases, so does the need for rice as the main staple food element. However, production in Indonesia is still not sufficient to meet these needs. Factors affecting rice production include superior varieties, properfertilization, pest and disease control, goodtillage, and a good irrigation system. On these factors, some are implemented into this study which aimed to determine the effect of inorganic fertilizer doses with the addition of biological fertilizers on the growth and production of rice plants. The research was conducted at IPB Sawah Baru ExperimentalFarm from November 2023 to March 2024. The experimental design used was the Split- Plot Randomized Complete Group Design (RCGD) which has two factors, namely inorganic fertilizer as the main plot with two levels, namely 100% of the recommended dose (N1) and 50% of the recommended dose (N2). The second factor is biological fertilizer as a subsidiary plot with five levels, namely no biological fertilizer (P0), biological fertilizer type 1 (P1), biological fertilizer type 2 (P2), biological fertilizer type 3 (P3), and biological fertilizer type 4 (P4). There was a significant effect on the components of growth and production of rice plants, namely the number of vegetative tillers, plantheight, flowering age, number of empty grains, total grain number, grain density, and dry weight of panicles.
