|---|
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk: (1) Mengetahui pengaruh macam pupuk N terhadap serapan N dan Si pada masa tanam ke II pada tanah entisol. (2) Mengetahui pengaruh dosis pupuk nitrogen (N) terhadap serapan N dan Si pada masa tanam ke II pada tanah entisol. (3) Mengetahui pengaruh macam pupuk N terhadap pertumbuhan dan produksi tanaman padi pada masa tanam ke II pada tanah entisol. (4) Mengetahui pengaruh dosis pupuk nitrogen (N) terhadap varietas IR36 pada masa tanam ke II pada tanah entisol. (5). Mengetahui pengaruh interaksi macam pupuk dan dosis N terhadap serapan N, Si, pertumbuhan, dan produksi tanaman padi varietas IR36 pada tanah entisol. Penelitian dilaksanakan di Screen House Fakultas Pertanian Universitas Jenderal Soedirman Purwokerto dan Laboratorium Tanah Fakultas Pertanian Universitas Jenderal Soedirman. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri dari 2 faktor percobaan. Faktor pertama adalah macam pupuk N pada masa tanam ke II (pupuk urea, pupuk NZeo-SR Plus coating 1%, pupuk Nzeo-SR Plus coating 3%). Faktor kedua adalah 3 dosis pupuk N (0kg/ha, 100kg/ha, 200kg/ha). Data hasil pengamatan dianalisis dengan menggunakan analisis sidik ragam untuk mengetahui pengaruh perlakuan dan apabila hasilnya beda nyata dilakukan uji lanjut Duncan’s Multiple Range Test (DMRT) 5%. Variabel yang diamati meliputi klorofil tanaman, KTK tanah, N tersedia, N total, Si tersedia, N serapan, Si serapan, dan bobot 1000 butir. Hasil penelitian menunjukan bahwa (1) Macam pupuk N mampu meningkatkan N serapan (9,5%) dan Si serapan (0,23%) pada masa tanam ke II tanah entisol. (2) Dosis pupuk N tidak mampu meningkatkan serapan N dan serapan Si pada masa tanam ke II tanah entisol. (3) Macam pupuk N mampu meningkatkan Si tersedia (0,72%), namun tidak mampu meningkatkan klorofil tanaman, KTK tanah, N tersedia, N total, dan bobot 1000 butir pada masa tanam ke II tanah entisol. (4) Dosis pupuk N mampu meningkatkan N total (0,63%), namun tidak mampu meningkatkan klorofil tanaman, KTK tanah, N tersedia, Si tersedia, dan bobot 1000 butir pada masa tanam ke II tanah entisol. (5) Tidak terjadi interaksi macam pupuk N dan dosis N pada semua variabel. |

| Abtrak (Bhs. Inggris) | This study aims to: (1) determine the effect of the type of N fertilizer on the uptake of N and Si during the second planting period on entisol soils. (2) Knowing the effect of the dose of nitrogen fertilizer (N) on the uptake of N and Si at the second planting period in entisol soil. (3) Knowing the effect of N fertilizer on the growth and production of rice plants during the second planting period on entisol soils. (4) To determine the effect of the dose of nitrogen fertilizer (N) on the IR36 variety at the second planting period on entisol soil. (5). To determine the interaction effect of fertilizer type and N dose on N, Si uptake, growth, and production of IR36 rice on entisol soil. The research was carried out at the Screen House of the Faculty of Agriculture, Jenderal Sudirman University, Purwokerto and the Soil Laboratory of the Faculty of Agriculture, Jenderal Sudirman University. This study used a Completely Randomized Block Design (RAKL) which consisted of 2 experimental factors. The first factor is the type of N fertilizer at the second planting period (urea fertilizer, NZeo-SR Plus coating 1%, fertilizer Nzeo-SR Plus coatings 3%). The second factor is 3 doses of N fertilizer (0kg/ha, 100kg/ha, 200kg/ha). Observational data were analyzed using analysis of variance to determine the effect of treatment and if the results were significantly different, the Duncan's Multiple Range Test (DMRT) 5% was further tested. The variables observed included plant chlorophyll, soil CEC, available N, total N, available Si, N uptake, Si uptake, and weight of 1000 grains. The results showed that (1) kinds of N fertilizer were able to increase N uptake (9.5%) and Si uptake (0.23%) during the second planting period of entisol soil. (2) The dose of N fertilizer was not able to increase N uptake and Si uptake at the second planting period of entisol soil. (3) The type of N fertilizer was able to increase available Si (0.72%), but was not able to increase plant chlorophyll, soil CEC, available N, total N, and weight of 1000 grains at the second planting period of entisol soil. (4) The dose of N fertilizer was able to increase total N (0.63%), but was not able to increase plant chlorophyll, soil CEC, available N, available Si, and weight of 1000 grains at the second planting period of entisol soil. (5) No interaction between the type of N fertilizer and the dose of N in all variables observed. |
