| Judul Artikel | PENGARUH PEMBERIAN PUPUK NPK-SR DENGAN BERBAGAI DIAMETER ZEOLIT ALAM DAN TAKARAN KOMPOS TERHADAP SERAPAN K DAN HASIL PADI SAWAH (Oryza sativa L.) PADA TANAH ULTISOL |
| Abstrak (Bhs. Indonesia) | ABSTRAK Tujuan penelitian adalah mengetahui pengaruh pemberian pupuk NPK-SR dengan berbagai diameter zeolit alam dan takaran kompos terhadap serapan K dan hasil padi sawah di tanah Ultisol, dan mengetahui pengaruh interaksi diantara keduanya. Penelitian telah dilaksanakan di Laboratorium Tanah dan Sumber Daya Lahan, Laboratorium Agronomi dan Hortikultura, dan kebun percobaan screen house A5 Fakulas Pertanian Universitas Jenderal Soedirman, Purwokerto. Penelitian ini dilakukan dengan rancangan acak kelompok lengkap (RAKL) yang terdiri dari dua faktor dengan tiga ulangan. Faktor pertama adalah pemberian pupuk NPK-SR dengan berbagai diameter zeolit alam: P0 (tanpa pemberian pupuk NPK-SR dan zeolit), P1 (pupuk NPK-SR diameter zeolit alam 30 mesh), P2 (pupuk NPK-SR diameter zeolit alam 35 mesh), P3 (pupuk NPK-SR diameter zeolit alam 60 mesh), P4 (pupuk NPK-SR diameter zeolit alam 100 mesh) dan P5 (pupuk NPK-SR diameter zeolit alam 140 mesh). Faktor kedua adalah takaran kompos: K0 (0 t/ha), K1 (20 t/ha), dan K2 (40 t/ha). Variabel pengamatan penelitian ini meliputi: serapan K, persentase gabah bernas, bobot gabah kering panen, bobot gabah kering giling dan bobot 1000 gabah. Hasil penelitian menunjukkan bahwa Pupuk NPK-SR dengan berbagai diameter zeolit alam tidak berpengaruh terhadap serapan K dan hasil padi sawah di tanah Ultisol. Takaran kompos meningkatkan serapan K, bobot gabah kering panen, bobot gabah kering giling, bobot 1000 gabah dan persentase gabah bernas. |
| Abtrak (Bhs. Inggris) | ABSTRACT The purpose of this study was to determine the effect of application of NPK-SR fertilizer with various diameters of natural zeolite and compost dosage on K uptake and lowland rice yields on Ultisol soil, and to determine the effect of the interaction between the two. The research has been carried out at the Laboratory of Soil and Land Resources, Laboratory of Agronomy and Horticulture, and the experimental garden of screen house A5, Faculty of Agriculture, Jenderal Soedirman University, Purwokerto. This study used a Completely Randomized Block Design (CRBD) with two factors with three replications. The first factor is the application of NPK-SR fertilizer with various diameters of natural zeolite: P0 (without NPK-SR fertilizer and zeolite), P1 (NPK-SR fertilizer with 30 mesh diameter of natural zeolite), P2 (NPK-SR fertilizer with 35 mesh diameter of natural zeolite), P3 (NPK-SR fertilizer with 60 mesh diameter of natural zeolite), P4 (NPK-SR fertilizer with 100 mesh diameter of natural zeolite) and P5 (NPK-SR fertilizer with 140 mesh diameter of natural zeolite). The second factor is the compost dosage: K0 (0 t/ha), K1 (20 t/ha), and K2 (40 t/ha). The observational variables of this study included: K uptake, percentage of filled grain, weight of dry grain harvested, weight of milled dry grain and weight of 1000 grain. The results showed that NPK-SR fertilizer with various diameters of natural zeolite had no effect on K uptake and lowland rice yields on Ultisol soil. The compost dose increased K uptake, weight of harvested dry grain, weight of milled dry grain, weight of 1000 grain and percentage of fiiled grain. |
