ABSTRACT


The aim of the research is to determine the application of Azolla fertilizer (Azolla pinnata) as an additional element of nitrogen nutrients in improving the result of rice harvast (Oryza sativa L.). This research was carried out in Balung Lor Village, Balung District, Jember Regency, East Java Province. The time of the research was carried out in December 2017 to March 2018. The research used factorial 2-RB Randomized Design (RBD) method. The first factor was the application of urea (N) with 3 levels: urea 0 kg / ha, urea 100 kg / ha), and urea 250 kg / ha. The second factor is the application of Azolla pinnata fertilizer with 3 levels: giving 3 tons of azolla / ha, giving 5 tons of azolla / ha, and giving 7 tons of azolla / ha. The results showed that the best treatment of urea fertilizer at a dose of 250kg / ha had a very significant effect on plant height aged 30 and 60 HST, number of tillers aged 30 and 60 HST, harvested dry grain (GKP) plots and samples, dry grain stores (GKS) plots and sample, number of grains per panicle, number of panicles per clump, and weight of 1000 seeds. The treatment of 7 tons of azolla fertilizer / ha has a very significant effect on harvested dry grain (GKP) plots and samples, dry grain storage (GKS) plots and samples, the number of grains of each panicle, while for the interaction between the treatment of 250 kg urea fertilizer / ha and azolla fertilizer 7 tons / ha (N3A3) had a very significant effect on dry grain harvested plot (GKP), dry grain store plot (GKS), and significantly affected dry grain harvested samples (GKP), dry storage sample grain (GKS).


Keywords: Rice (Oryza sativa L.) Ciherang variety, Urea fertilizer, Azolla pinnata fertilizer.

ABSTRAK


Penelitian ini dilakukan dengan tujuan untuk mengetahui Aplikasi Pupuk Azolla (Azolla pinnata) Sebagai penyumbang Unsur Hara Nitrogen Dalam Meningkatkan Hasil Panen Padi Sawah (Oryza sativa L.). Penelitian ini dilaksanakan di Desa Balung Lor, Kecamatan Balung, Kabupaten Jember, Provinsi Jawa Timur. Waktu pelaksanaan penelitian dilakukan pada bulan Desember 2017 sampai dengan bulan Maret 2018. Penelitian menggunakan metode Rancangan Acak Kelompok (RAK) 2 faktorial. Faktor pertama ialah aplikasi pupuk urea (N) dengan 3 taraf: pemberian urea 0 kg/ ha, pemberian urea 100 kg/ ha ), dan pemberian urea 250 kg/ ha. Faktor kedua ialah aplikasi pupuk Azolla pinnata dengan 3 taraf: pemberian azolla 3 ton/ ha, pemberian azolla 5 ton/ ha, dan pemberian azolla 7 ton/ ha. Hasil penelitian menunjukan perlakuan terbaik pupuk urea dengan dosis 250kg/ ha berpengaruh sangat nyata terhadap tinggi tanaman umur 30 dan 60 HST, jumlah anakan umur 30 dan 60 HST, gabah kering panen (GKP) plot dan sampel, gabah kering simpan (GKS) plot dan sampel, jumlah bulir tiap malai, jumlah malai tiap rumpun, dan berat 1000 benih. Perlakuan pupuk azolla 7 ton/ ha berpengaruh sangat nyata terhadap gabah kering panen (GKP) plot dan sampel, gabah kering simpan (GKS) plot dan sampel, jumlah bulir tiap malai, Sedangkan untuk interaksi antara perlakuan pupuk urea 250 kg/ ha dan pupuk azolla 7 ton/ ha (N3A3) berpengaruh sangat nyata terhadap gabah kering panen plot (GKP), gabah kering simpan plot (GKS), dan berpengaruh nyata terhadap gabah kering panen sampel (GKP), gabah kering simpan sampel (GKS).
