ABSTRAKPenelitian dilakukan untuk mengetahui pengaruh aplikasi batuan fosfat pada produksi dan kandungan makronutrien alfalfa dibandingkan dengan pupuk fosfat kimia. Penelitian menggunakan rancangan acak lengkap yang berpola faktorial 3x3. Faktor pertama adalah sumber pupuk P yang berbeda: Guizhou Phosphate Rock (GPR), Jingxiang Phosphate Rock (JPR), dan Single Super Phosphate (SSP). Faktor kedua adalah dosis pupuk P: 75, 100, dan 125 mg P2O5/kg tanah. Perlakuan kontrol (tanpa penambahan pupuk P, CK) telah ditambahkan sebagai perbandingan dengan perlakuan. Hasil menunjukkan bahwa produksi alfalfa tertinggi dihasilkan dari penambahan JPR, dimana GPR dan SSP menghasilkan kandungan nutrien lebih tinggi pada alfalfa disbanding dengan JPR. Kesimpulan dari penelitian ini adalah aplikasi batuan fosfat memiliki efek yang sama pada pertumbuhan alfalfa dibandingkan dengan SSP pada kondisi perlakuan tersebut.Kata kunci: alfalfa, batuan fosfat, makronutrien, produksi ABSTRACTThe objective of this study was to evaluate the effectiveness of phosphate rocks (PRs) fertilizer compared to chemical P fertilizer for the best crop production and macronutrients of alfalfa. A completely randomized design under 3x3 factorial patterns was used in this research. The first factor was different sources of P fertilizer: Guizhou Phosphate Rock (GPR), Jingxiang Phosphate Rock (JPR), and Single Super Phosphate (SSP). The second factor was level of P fertilizer: 75, 100, and 125 mg P 2 O 5 /kg soil. A control treatment (without addition of P fertilizer, CK) was added as a comparison with the treatments. The results showed that JPR was the best for alfalfa production, whereas GPR and SSP were better for nutrient content in the alfalfa tissue than JPR. On the whole, phosphate rocks had similar effect on alfalfa growth compared to SSP at the experimental conditions.
