      Abstract
      Ketergantungan pembibitan kelapa sawit pada pupuk anorganik mendorong pemanfaatan limbah organik pabrik kelapa sawit sebagai alternatif sumber hara berkelanjutan. Penelitian bertujuan menganalisis pengaruh jenis dan dosis pupuk organik, dosis rock phosphate, serta interaksinya terhadap pertumbuhan bibit kelapa sawit fase pre–nursery. Penelitian menggunakan rancangan faktorial tiga faktor, yaitu jenis limbah organik (fiber, cangkang, abu boiler, POME), dosis pupuk organik (20–40%), dan dosis rock phosphate (0–100%), dengan pengamatan selama 10 minggu setelah tanam. Hasil menunjukkan jenis pupuk organik berpengaruh sangat nyata terhadap seluruh peubah pertumbuhan, dengan limbah POME secara konsisten menghasilkan pertumbuhan terbaik. Dosis pupuk organik dan rock phosphate secara tunggal tidak berpengaruh nyata, dan interaksi antarfaktor umumnya tidak signifikan. Temuan ini mengimplikasikan bahwa pemilihan jenis pupuk organik, khususnya POME pada dosis rendah, lebih menentukan keberhasilan pembibitan dibandingkan peningkatan dosis pupuk organik maupun aplikasi rock phosphate.
       
      Reliance on inorganic fertilizers in oil palm nurseries has encouraged the use of palm oil mill organic waste as a sustainable nutrient alternative. This study analyzed the effects of organic fertilizer type and dose, rock phosphate dose, and their interactions on oil palm seedling growth at the pre–nursery stage. A three-factor factorial design was applied, comprising organic waste type (fiber, shell, boiler ash, POME), organic fertilizer dose (20–40%), and rock phosphate dose (0–100%), observed for 10 weeks after planting. Organic fertilizer type significantly affected all growth variables, with POME waste consistently producing the best growth performance. Organic fertilizer and rock phosphate doses showed no significant single effect, and most interactions were non-significant. These findings imply that organic fertilizer type, particularly POME at a low dose, is more critical to nursery success than increasing fertilizer dose or applying rock phosphate.
