Zaenal Mutaqin. 2012. Pengaruh Pemberian Pupuk NPK dengan Suplemen Pupuk Organik Cair Terhadap Fe-total, Fe-tersedia, Serapan Fe dan Hasil Padi Sawah (Oryza sativa L.) Varietas INPARI 13 Pada Fluvaquentic Epiaquepts. Dibawah Bimbingan E. Hidayat Salim dan Anne Nurbaity.
Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk NPK dengan suplemen pupuk organik cair terhadap Fe-total, Fe-tersedia, Serapan Fe dan hasil padi sawah (Oryza sativa L.) Varietas INPARI 13 pada Fluvaquentic Epiaquepts. Percobaan ini dilaksanakan di kebun percobaan Pengelolaan Tanah dan Air, Jurusan Ilmu Tanah dan Sumberdaya Lahan, Fakultas Pertanian Universitas Padjadjaran, Jatinangor, Kabupaten Sumedang Jawa Barat, pada bulan April sampai dengan bulan Agustus 2011.
Rancangan percobaan yang digunakan yaitu Rancangan Acak Kelompok (RAK) dengan sepuluh perlakuan dan tiga kali ulangan, yaitu terdiri dari : A (kontrol); B (1 NPK + 0 POC); C (1 NPK + ½ POC); D (0 NPK + 1 POC); E (¼ NPK + 1 POC); F (½ NPK + 1 POC); G (¾ NPK + 1 POC); H (1 NPK + 1 POC); I (1 NPK + 1½ POC); J (1 NPK + 2 POC).
Hasil penelitian menunjukkan bahwa pemberian pupuk NPK dengan suplemen pupuk organik cair berpengaruh nyata terhadap Fe-tersedia, serapan Fe dan hasil padi sawah (Oryza sativa L.), tetapi tidak berpengaruh nyata terhadap Fe-total. Pemberian satu dosis pupuk NPK dengan satu dosis suplemen pupuk organik cair dapat memberikan hasil terbaik padi sawah, sebesar 4,34 kg petak-1
setara dengan 6,14 ton ha-1.
ii ABSTRACT
Zaenal Mutaqin. 2012. The Effect of NPK Fertilizer with Suplement of Liquid Organic Fertilizer on Total-Fe, Available Fe, Fe Uptake and Yield of INPARI 13 Variety s Rice (Oryza sativa L.) in Fluvaquentic Epiaquepts. Supervised by E. Hidayat Salim and Anne Nurbaity.
The aim of this research was to determine the effect of NPK fertilizer with suplement of liquid organic fertilizer (LOF) on total-Fe soil, available Fe soil, Fe uptake and yield of INPARI 13 Variety s Rice (Oryza sativa L.) grown on Fluvaquentic Epiaquepts. The research was conducted at field station of Soil and Water Management, Soil Science and Land Resources Department, Faculty of Agliculture Padjadjaran University, Jatinangor, Sumedang West Java, from April until August 2011.
The experiment used a Randomized Block Design (RBD) with ten treatment and three replications, consisted of : A (control); B (1 NPK + 0 LOF); C (1 NPK + ½ LOF); D (0 NPK + 1 LOF); E (¼ NPK + 1 LOF); F (½ NPK + 1 LOF); G (¾ NPK + 1 LOF); H (1 NPK + 1 LOF); I (1 NPK + 1½ LOF); J (1 NPK + 2 LOF).
The result of experiment showed that there were significant effects between NPK fertilizer with suplement of liquid organic fertilizer on soil Fe available, Fe uptake and yield of rice, but there was no significant effect on total-Fe soil. The application of one dose NPK fertilizer with one dose suplement of liquid organic fertilizer resulted the yield of highest rice that was 4,34 kg block-1, equal to 6,14
ton ha-1.
