| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui pengaruh pemberian dosis pupuk NZEO-SR PLUS terhadap sifat kimia tanah, serapan N, dan produksi bawang merah, dan mengetahui pengaruh pemberian jarak tanam terhadap sifat kimia tanah, serapan N, dan produksi bawang merah. Penelitian dilaksanakan di Desa Pliken, Kecamatan Kembaran, Kabupaten Banyumas, serta di Laboratorium Ilmu Tanah dan Sumberdaya Lahan, Fakultas Pertanian, Universitas Jenderal Soedirman, Purwokerto, menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan dua faktor perlakuan yaitu dosis pupuk NZEO-SR Plus, dan jarak tanam, diulang sebanyak tiga ulangan. Variabel yang di amati yaitu seperti pH tanah, daya hantar listrik tanah, N-Tersedia tanah, P-Tersedia tanah, K-dd tanah, kapasitas tukar kation tanah, serapan nitrogen tanaman, bobot segar umbi bawang merah, dan bobot kering umbi bawang merah. Hasil penelitian menunjukkan bahwa pemberian dosis pupuk NZEO-SR Plus berpengaruh nyata pada pengamatan minggu keempat nilai daya hantar listrik tanah dan nilai N-tersedia tanah. Pada nilai P-tersedia, K-dd, kapasitas tukar kation, serapan nitrogen, bobot segar umbi, dan bobot kering umbi tidak berpengaruh nyata. Perlakuan dosis pupuk NZEO-SR Plus 250 kg/ha, NZEO-SR Plus 500 kg/ha, NZEO-SR Plus 750 kg/ha, dan NZEO-SR Plus 1000 kg/ha dapat meningkatkan nilai variabel N-tersedia, kapasitas tukar kation, serapan nitrogen, bobot segar umbi, dan bobot kering umbi. Perlakuan jarak tanam memberikan pengaruh nyata terhadap bobot segar umbi dan bobot kering umbi. Sementara pada perlakuan jarak tanam 15x20 cm memiliki nilai serapan nitrogen tertinggi dibandingkan dengan jarak tanam 15x15 cm. Pada variabel sifat kimia tanah seperti pH tanah, daya hantar listrik tanah, N-tersedia tanah, P-tersedia tanah, K-dd tanah, dan kapasitas tukar kation tanah dengan adanya perlakuan jarak tanam tidak memberikan pengaruh nyata. |

| Abtrak (Bhs. Inggris) | This study aims to determine the effect of NZEO-SR PLUS fertilizer dosage on soil chemical properties, N uptake, and shallot production, and determine the effect of spacing on soil chemical properties, N uptake, and shallot production. The research was carried out in Pliken Village, Kembaran District, Banyumas Regency, and at the Laboratory of Soil Science and Land Resources, Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, using a Completely Randomized Block Design (RCBD) with two treatment factors, namely the dose of NZEO-SR Plus fertilizer, and spacing, repeated three times. The variables observed were soil pH, soil electrical conductivity, N-Available soil, P-Available soil, K-dd soil, soil cation exchange capacity, plant nitrogen uptake, fresh weight of shallot bulbs, and dry weight of shallot bulbs. The results showed that the dose of NZEO-SR Plus fertilizer had a significant effect on the fourth week of observation of the electrical conductivity of the soil and the value of available N of the soil. The value of available P, K-dd, cation exchange capacity, nitrogen uptake, tuber fresh weight, and tuber dry weight had no significant effect. The dosage treatment of NZEO-SR Plus 250 kg/ha, NZEO-SR Plus 500 kg/ha, NZEO-SR Plus 750 kg/ha, and NZEO-SR Plus 1000 kg/ha can increase the value of the available N-variable, cation exchange capacity, nitrogen uptake, tuber fresh weight, and tuber dry weight. Spacing treatment gave a significant effect on the fresh weight of tubers and dry weight of tubers. While the treatment with a spacing of 15x20 cm had the highest nitrogen uptake value compared to a spacing of 15x15 cm. The variables of soil chemical properties such as soil pH, soil electrical conductivity, N-available soil, P-available soil, K-dd soil, and soil cation exchange capacity with the treatment of plant spacing did not have a significant effect. |
