ABSTRAK
Respons Nitrogen dan Azolla terhadap Pertumbuhan Tanaman Padi Varietas Mira
I dengan Metode SRI. Penelitian ini dilakukan di Kampung Cisadap, Desa Bunter,
Kecamatan Sukadana, Kabupaten Ciamis, Provinsi Jawa Barat dari Bulan Januari
sampai Bulan Mei 2011 untuk mempelajari respons pertumbuhan tanaman padi
yang diberi pupuk nitrogen dan Azolla michrophylla pada budidaya padi sawah
System Of Rice Intensification . Penelitan ini menggunakan 5 dosis pupuk nitrogen
(0 %, 25 %, 50 %, 75 %, 100 %) dari pupuk nitrogen yang direkomendasikan
yaitu N 92 kg ha-1 (urea 200 kg ha-1), serta menggunakan Azolla michrophylla
sebanyak 1,13 ton ha-1. Hasil penelitian menunjukkan bahwa pemberian dosis
pupuk nitrogen sebanyak 50 % (100 kg ha-1) dan pemberian Azolla michrophylla
sebanyak 1,13 ton ha-1 memberikan hasil yang baik pada parameter tinggi
tanaman 2-6 MST, jumlah anakan 2-7 MST. Interaksi antara penggunaan dosis 50
% pupuk nitrogen dan 1,13 Azolla michrophylla terjadi pada tinggi tanaman umur
7 MST, dan bobot kering tanaman.
Kata kunci : nitrogen, Azolla , pertumbuhan, padi sawah, SRI

ABSTRACT
Nitrogen and Azolla Respons on Growth of Rice Plant of Mira-I Variety With SRI
Methode. The research was conducted in Cisadap, Bunter Village, District of
Sukadana, Ciamis Regency, West Java Province from January to May 2011. This
study was carried out to know the response of growth of rice plant wich was
fertilized by nitrogen fertilizer and Azolla michrophylla using the system of rice
intensification. This research used five dozes of nitrogen fertilizer (0 %, 25 %, 50
%, 75 %, 100 %) from N 92 kg ha-1 as a recomended nitrogen fertilizer (urea
200 kg ha-1), and also 1,13 ton ha-1 Azolla michrophylla . The result obtained
from this research showed that the application of N fertilizer at 50 % of the recommend dose (100 kg ha-1) with adding Azolla at a rate of 1.13 t ha-
1 gave good result in the terms of plant height at 2-6 weeks after planting and
number of tillers at 2-7 weeks after planting. Interaction of the 50 % N
fertilizer from the recommended dose planting 1,13 t ha-1 give the highest dry
weight of Azolla of plants at seven weeks after planting.
