Penelitian bertujuan untuk mengetahui  pengaruh pupuk majemuk NPK-Zeo Granul berbagai diameter dan pupuk organik terhadap ketersediaan dan serapan P dan K serta hasil tanaman bawang merah pada Ultisol dan mengetahui pengaruh interaksi antara diameter pupuk majemuk NPK-Zeo granul dan pupuk organik terhadap ketersediaan dan serapan P dan K serta hasil tanaman bawang merah pada Ultisol. Penelitian berupa percobaan polibag menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan 2 faktor dan 3 ulangan. Faktor pertama adalah diameter pupuk majemuk NPK-Zeo Granul (tanpa pupuk, diameter 1mm,2mm,3mm,4mm,5mm). Faktor kedua adalah pupuk organik (tanpa pupuk dan pupuk setara 40ton/ha). Variabel yang diamati adalah K tersedia tanah, P tersedia tanah, serapan P daun, serapan K daun, jumlah umbi, diameter umbi, bobot tanaman segar, bobot tanaman kering, bobot umbi kering eskip, dan bobot umbi kering oven. Data dianalisis dengan uji F dan DMRT pada taraf kesalahan 5%. Hasil penelitian menunjukkan bahwa penggunaan pupuk NPK-Zeo Granul dengan berbagai diameter dapat meningkatkan P tersedia tanah, K tersedia tanah, serapan P, seraoan K, dan jumlah umbi secara linier. Penggunaan pupuk organik setara 40 ton/ha dapat meningkatkan P tersedia tanah, K tersedia tanah, serapan P, serapan K, jumlah umbi, diameter umbi, bobot umbi kering eskip, dan bobot umbi kering oven. Tidak terdapat pengaruh interaksi pupuk majemuk NPK-Zeo Granul berbagai diameter dan pupuk organik pada ketersediaan unsur hara, serapan unsur hara, dan hasil tanaman bawang merah, namun penggunaan pupuk NPK-Zeo Granul sampai 5mm dapat meningkatkan hasil jika digunakan bersamaan dengan pupuk organik setara 40 ton/ha.

The research aims to determine the effect of NPK-Zeo Granule fertilizer of various diameters and organic fertilizer on availability and uptake P and K, and shallot yield in Ultisol, also find out the effect of compound fertilizer NPK-Zeo granule diameter and organic fertilizer variation on P and K availability, absorption, and yield of shallots in Ultisol. The research is a polybag experiment using a Completely Randomized Block Design (CRBD) with 2 factors and 3 replications. The diameter of the compound fertilizer NPK-Zeo Granules (without fertilizer, 1 mm diameter, 2 mm, 3 mm, 4 mm, and 5 mm) is the first factor. Compost (no organic fertilizer and fertilizer equivalent to 40 tons/ha) is the second factor. The variables observed included soil available K, soil available P, P uptake of leaf, K uptake of leaf, number of the bulbs, the diameter of bulb, fresh weight of the plant, dry weight of the plant, dry weight of bulb eskip, and dry weight of bulb oven. Data were analyzed by analysis of variance  and DMRT at an error level of 5%. The results showed that the application of NPK-Zeo Granule fertilizer with various diameters could increase soil available P, soil available K, P uptake, K uptake, and number of bulb linearly. The the application of organic fertilizer equivalent to 40 tons/ha can increase soil available P, soil available K, P uptake, K uptake, number of bulb, diameter of diameter, weight of eskip dried bulb, and weight of oven-dried bulb. There is no interaction effect of compound fertilizer NPK-Zeo Granules of various diameters and organic fertilizers on availability nutrient, uptake of nutrient, and the yield of shallots, but the application of NPK-Zeo Granule fertilizers up to 5mm can increase yields if used together with organic fertilizer equivalent to 40 tons/ha.
