Aplikasi Pupuk N Terhadap Produksi dan Viabilitas Enam Varietas Padi Hibrida (Oryza sativa L.) Applications of N Fertilizer Against Yield Potential and Seed Viability Six Rice Hybrid Variety (Oryza sativa L.). Advisor : Dr. Rizal, SP, MP and Dwi Rahmawati, SP, MP Nanang Fathor Al-Aslam Seed Production Engineering Program, Department of Agricultural Production ABSTRACT Research Applications of N Fertilizer Against Production and Seed Viability Six Rice Hybrid Variety (Oryza sativa L.) conducted for 5 months. starting in Maret 2014 – Agustus 2014. The experiments takes place in the field and laboratory of Jember Polytechnic with a height level of ± 89 dpl. This research uses Randomized Block Design (RBD) with 2 factors. First factor is dose N fertilizer applications, consisting of: first dose (150 kg/ha), second dose (250 kg/ha) and third dose 350 kg/ha). Second factor is six rice of Hybrid Variety, consisting of: Once variety (HIPA Jatim 1), second variety (HIPA 10), third variety (HIPA Jatim 3), fourth variety (HIPA 9), fiveth variety (HIPA Jatim 2), and sixth variety (Segara Anak) . The results shows that the treatment of aplication dose has significant effect on high vegetative of plant phase, rice of branches vegetative total, rice of branches productive total, long rice tassel, unhulled rice per tassel total, unhulled rice full per tassel total, yield potential and germination capacity. Meanwhile, the results shows that the treatment of aplication variety has significant effect on high generatif of plant phase and thousands grain weight. Interaction both two treatment has significant effect on thousands grain. Key words: N fertilizer application, yield potential, and rice of hybrid variety.
