Krisis pangan menjadi tantangan utama akibat meningkatnya kebutuhan pangan dan menyempitnya lahan pertanian. Perubahan iklim yang tidak menentu seperti kekeringan, turut memperparah kondisi ini dan berdampak langsung pada penurunan produksi padi nasional. Salah satu solusi yang dapat diterapkan adalah optimalisasi pertumbuhan dan hasil padi melalui pemberian amandemen tanah serta pemupukan berimbang. Penelitian ini bertujuan untuk mengetahui pertumbuhan dan hasil tanaman padi akibat perlakuan mikoriza, kompos, vermikompos, dosis pupuk NPK dan tingkat kekeringan terhadap pertumbuhan dan hasil tanaman padi varietas Inpari 42 Agritan. Penelitian ini dilaksanakan di Rumah Kaca 2 dan Laboratorium Fisiologi Tumbuhan, Fakultas Pertanian, Universitas Syiah Kuala, Banda Aceh dari bulan Juli 2024 - November 2024. Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) pola factorial split-split plot dengan tiga faktor, yaitu (tanpa mikoriza, mikoriza 20 g tanaman⁻¹ + kompos 50 g tanaman⁻¹ dan mikoriza 20 g tanaman⁻¹ + vermikompos 50 g tanaman⁻¹), dosis pupuk NPK (600 dan 900 kg ha⁻¹), dan perlakuan kekeringan (penyiraman normal normal dan kekeringan fase reproduktif). Berdasarkan hasil penelitian, interaksi antara mikoriza, kompos, vermikompos, dosis pupuk NPK, dan tingkat kekeringan berpengaruh sangat nyata terhadap berbagai parameter pertumbuhan dan hasil padi Inpari 42 Agritan, seperti tinggi tanaman, jumlah dan panjang daun, nilai SPAD, panjang akar, berat brangkasan basah dan kering, berat gabah berisi dan hampa, potensi hasil, serta indeks ketahanan kekeringan. Kombinasi terbaik diperoleh pada perlakuan mikoriza + kompos dan dosis pupuk NPK 900 kg ha⁻¹ di bawah kekeringan fase reproduktif.

The food crisis is a major challenge due to increasing food demand and shrinking agricultural land. Unpredictable climate change, such as drought, has exacerbated this situation and directly impacted national rice production. One solution that can be implemented is optimizing rice growth and yield through soil amendments and balanced fertilization. This study aims to determine the growth and yield of rice plants due to mycorrhizal treatments, compost, vermicompost, NPK fertilizer dosage, and drought levels on the growth and yield of Inpari 42 Agritan rice varieties. This research was conducted at Greenhouse 2 and Plant Physiology Laboratory, Faculty of Agriculture, Syiah Kuala University, Banda Aceh from July 2024 - November 2024. The research was conducted using a Randomized Block Design (RBD) factorial split-split plot pattern with three factors, namely (without mycorrhiza, mycorrhiza 20 g plant⁻¹ + compost 50 g plant⁻¹ and mycorrhiza 20 g plant⁻¹ + vermicompost 50 g plant⁻¹), NPK fertilizer doses (600 and 900 kg ha⁻¹), and drought treatment (normal watering and reproductive phase drought). Based on the research results, the interaction between mycorrhiza, compost, vermicompost, NPK fertilizer dosage, and drought level had a very significant effect on various growth and yield parameters of Inpari 42 Agritan rice, such as plant height, number and length of leaves, SPAD value, root length, wet and dry stover weight, full and empty grain weight, yield potential, and drought resistance index. The best combination was obtained in the mycorrhiza + compost treatment and NPK fertilizer dosage of 900 kg ha⁻¹ under reproductive phase drought.
