| Abstrak (Bhs. Indonesia) | Pemupukan yang tepat merupakan salah satu faktor utama dalam rangka peningkatan produktivitas padi. Terdapat alternatif penggunaan pupuk yaitu pupuk NZEO-SRPlus. Pupuk NZEO-SRPlus merupakan pupuk yang terbuat dari bahan utama zeolite alam serta mineral lempung 2:1 (montromolilonite) sebagai bahan perekatnya yang diperkaya dengan unsur Si serta coating nano zeolite dan bahan humat. Pelapisan atau coating bertujuan untuk memperlambat pelepasan unsur N dari pupuk, sehingga dapat meningkatkan efisiensi pemupukan dan tanaman mempunyai kemampuan dalam ketahanan terhadap kondisi stress. Tujuan penelitian ini adalah mengetahui pengaruh dosis, waktu pemberian, dan interaksi pupuk NZEO-SRPlus terhadap: i) sifat kimia tanah Inceptisol: pH-H2O, potensial redoks, N-total tanah, serapan N oleh tanaman dan serapan Si oleh tanaman, ii) hasil padi: GKP dan GKG padi Ciherang Jumbo di tanah Inceptisol desa Maos Lor. Penelitian ini dilakukan di Laboratorium Ilmu Tanah, Fakultas Pertanian, Universitas Jenderal Soedirman dan lahan Maos Lor, Kecamatan Maos, Cilacap. Penelitian ini dirancang dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor perlakuan dan 3 ulangan. Faktor pertama adalah dosis pupuk NZEO-SRPlus coating 17% (N) yang terdiri dari: N0= 0 kg N/ha, N1= 50 kg N/ha, N2= 100 kg N/ha, N3= 150 kg N/ha, N4= 200 kg N/ha dan faktor yang kedua adalah cara pemberian (C) yang terdiri dari: C1= 7 HST dan C2= 7 dan 35 HST. Variabel penelitian yang diamati meliputi: pH-H2O, potensial redoks, N-total tanah, serapan N oleh tanaman, serapan Si oleh tanaman, GKP, dan GKG. Hasil penelitian menunjukan bahwa perlakuan dosis pupuk NZEO-SRPlus coating 17% berpengaruh terhadap peningkatan nilai serapan N oleh tanaman, serapan Si oleh tanaman, GKP, dan GKG. Waktu pemberian pupuk sebanyak 2 kali (7 dan 35 HST) memberikan pengaruh terhadap nilai potensial redoks, N-total tanah, serapan Si oleh tanaman, GKP, dan GKG, sedangkan pemberian 1 kali (7 HST) berpengaruh terhadap nilai serapan N oleh tanaman. Pemberian dosis 150 kg N/ha dengan 2 kali waktu pemberian pada awal 7 HST dan 35 HST memberikan hasil terbaik pada produksi padi Ciherang di lahan sawah Desa Maos Lor, Kecamatan Maos, Kabupaten Cilacap. |

| Abtrak (Bhs. Inggris) | Proper fertilization is one of the main factors in order to increase rice productivity. There is an alternative use of fertilizer, namely NZEO-SRPlus fertilizer. NZEOSRPlus fertilizer is a fertilizer made from the main ingredients of natural zeolite and clay minerals 2:1 (montromolilonite) as an adhesive enriched with Si elements and nano zeolite coatings and humic materials. Coating or coating aims to slow the release of element N from fertilizer, so as to improve the efficiency of fertilization and plants have the ability to withstand stress conditions. The purpose of this study was to determine the effect of dose, time of administration, and interaction of NZEO-SRPlus fertilizer on: i) chemical properties of Inceptisol soil: pH-H2O, redox potential, Ntotal soil, N absorption by plants and Si absorption by plants, ii) rice yield: dry grain harvesting (DGH) and milled dry grain (MDG) of Ciherang Jumbo rice in Inceptisol soil of Maos Lor village. This research was conducted in Soil Science Laboratory, faculty of Agriculture, Jenderal Sudirman University and Maos Lor land, Maos District, Cilacap. This study was designed using complete randomized design (CRD) with 2 treatment factors and 3 replications. The first factor is the dose of fertilizer NZEO-SRPlus coating 17% (N) which consists of: N0= 0 kg N/ha, N1= 50 kg N/ha, N2= 100 kg N/ha, N3= 150 kg N/ha, N4= 200 kg N/ha and the second factor is the way of administration (C) which consists of: C1= 7 day after planting (DAP) and C2= 7 and 35 day after planting (DAP). Research variables observed include: pH-H2O, redox potential, N-total soil, N absorption by plants, Si absorption by plants, DGH, and MDG. The results showed that the treatment dose of fertilizer NZEO-SRPlus coating 17% effect on increasing the value of N uptake by plants, Si uptake by plants, DGH, and MDG. Time of fertilizer application as much as 2 times (7 and 35 DAP) give effect to the value of redox potential, N-total soil, Si uptake by plants, DGH, and MDG, while giving 1 time (7 DAP) affect the value of N uptake by plants. Dosing of 150 kg N/ha with 2 times the time of administration at the beginning of 7 DAP and 35 DAP gave the best results on the production of Ciherang rice in rice fields in Maos Lor Village, Maos District, Cilacap Regency. |
