Abstract
Nowadays glutinous rice productivity is still low even though its production potential is very high. It is caused by the lackness of special technology for glutinous rice cultivation. Therefore we need cultivation techniques that can increase the production of glutinous rice plants. Application of urea fertilizer in a proper dosage and a proper seedlings age are expected to be able to increase glutinous rice production. This study aimed to get the right dosage of urea fertilizer and the proper age seedlings that can increase glutinous rice production. The study was designed using a Divided Plot Design arranged by Randomize Block Design, 2 factors (3x3). As Main Plot (PU) was the dosage of urea fertilizer (P), consisting of 3 levels: P1 = 100 kg ha-1, P2 = 200 kg ha-1 and P3 = 300 kg ha-1. As the plots (AP) were the age of seeds (U), consisting of 3 levels: U1 = 14 days, U2 = 21 days, and U3 = 28 days. Variables observed were plant height, number of tillers, number of leaves, leaf area, number of panicles per clump, panicle length, number of grains, number of grained rice, number of empty grains, number of seeds per panicle, fresh weight, dry weight, weight of 1000 grains, and grain weight per hectare. The results showed that the dosage of 300 kg ha-1 Urea (P3) and 14 days seedling ages (U1) showed a good response, so it can be recommended to be applied by the farmers. Keywords: Glutinous rice, urea fertilizer dosage, seedling age

Summary
Terdapat interaksi antara perlakuan dosis pupuk urea dan umur bibit terhadap tinggi tanaman pada umur 63 hst (Gambar 1). Gambar 1 memperlihatkan bahwa terdapat interaksi antara perlakuan dosis pupuk urea dan umur bibit pada jumlah anakan. Hal ini menunjukkan bahwa ada pengaruh antara pemberian dosis pupuk urea dan umur bibit yang berbeda terhadap jumlah anakan tanaman padi ketan. U1 (14 hari) dan U2 (21 hari) mengikuti pola linear artinya semakin meningkat dosis pupuk urea yang diberikan maka jumlah anakan tanaman akan semakin meningkat. Tabel 1 memperlihatkan bahwa perlakuan dosis pupuk urea berbeda nyata terhadap tinggi tanaman umur 70 dan 77 hst, sedangkan perlakuan umur bibit berbeda nyata terhadap tinggi tanaman umur 35 hst. Tinggi tanaman pada perlakuan dosis pupuk urea P3 (300 kg ha-1) dan perlakuan umur transplanting bibit U3 (28 hari) memperlihatkan tinggi tanaman terbesar. Rata-rata Tinggi Tanaman pada Perlakuan Dosis Pupuk Urea dan Umur Transplanting Bibit
