    Abstract Performances of Local Rice Cultivars in High Elevation Wetland of Alahan Panjang Village. An experiment on characters and yields of local rice cultivars of Alahan Panjang Village with its elevation of 1.200 m A.S.L., Solok District, West Sumatra Province was carried out during the WS of 2007. The experiment was arranged in a randomized completely block design with three replications. Treatments were 4 local rice cultivars, namely Putih Tawe, Randah Bukit, Kuning Randah, and Remaja. The rice crops were fertilized with urea, SP36, and potassium at the rate of 150, 75, and 50 kg/ha, respectively. Results of this assessment indicated that high yield of 5.30 and 5.03 t/ha were demonstrated by Randah Kuning and Putih Tawe, respectively. It was also observed that Randah Kuning and Putih Tawe seem to be resistant to leaf and neck blast. Abstrak Evaluasi empat varietas lokal padi sawah dataran tinggi Alahan Panjang (1.200 m dpl) telah dilakukan pada MH 2007. Kegiatan evaluasi ditata dalam rancangan acak kelompok dengan 3 ulangan, dengan ukuran plot 4 m x 6 m. Perlakuan adalah empat varietas padi lokal asal Alahan Panjang, yaitu Putih Tawe, Randah Bukit, Kuning Randah, dan Remaja. Padi ditanam dengan jarak tanam 25 cm x 25 cm dengan sistem legowo 4:1, dipupuk dengan urea, SP36, dan kalium dengan dosis berturut-turut 150 kg. 75 kg. dan 50 kg/ha. Pupuk urea diberikan bertahap, pertama 50 kg/ha urea bersama seluruh SP36 dan KCI diberikan saat pertanaman berumur 1 minggu. Pupuk susulan urea diberikan berdasarkan hasil pembacaan bagan warna daun dengan interval pengamatan 10 hari setelah pemupukan. Pengamatan dilakukan terhadap jumlah anakan, tinggi tanaman, serangan penyakit blas, jumlah gabah/malai, bobot 1.000 butir gabah isi, gabah hampa, gabah isi, dan produksi gabah (t/ha). Hasil pengkajian menunjukkan bahwa produksi gabah tertinggi diperoleh dari varietas Randah Kuning dan Putih Tawe, berturut-turut sebesar 5,30 t/ha dan 5,03 t/ha. Kedua varietas tersebut memiliki jumlah gabah/malai, bobot 1.000 butir gabah isi, dan gabah isi yang tinggi serta tahan terhadap penyakit blas daun dan blas leher.

    Abstract Performance of Local Lowland Rice Varieties in Three Different Environments. Field evaluation of Ceredek local variety of lowland rice to study the agronomic performance, yield components, and the yield potentials were conducted in Sumani (300 m above sea level), Katialo (600 m above sea level), and Rawang (900 m above sea level) in Solok District, during the DS of 2008. The experimental was arranged in randomized complete block design with three replications, with plot of 4 m x 4 m in size. The crops were fertilized with urea, SP36, and KCl, at the rates of 150, 100, and 50 kg/ha, respectively. Result of the assessment indicated that the best lowland rice varieties in the three test locations were Padi Kuning and Padi Kutu in which they yielded up to 4,6 t/ha with the average plant heights were 116.6 cm and 144.4 cm, respectively. Unfortunately, the two varieties were susceptible to lodging. The other two varieties (Ceredek Putih and Ceredek Merah) reached the average yield of 3,7 and 3,3 t/ha, respectively, they were resistant to lodging, medium plant height (103,6 cm and 107,0 cm, respectively), and mature at 142 DAT. Abstrak Pengujian varietas lokal padi sawah untuk mengevaluasi penampilan agronomi, komponen hasil, dan hasil telah dilakukan di Sumani (300 m dpl), Katialo (600 m dpl), dan Rawang (900 m dpl) di Kabupaten Solok pada MH 2008. Percobaan ditata dalam Rancangan Acak Kelompok (RAK) dengan tiga ulangan, ukuran plot 4 m x 4 m. Pertanaman dipupuk urea, SP36, dan KCl, dengan dosis berturut-turut 150 kg. 100 kg, dan 50 kg/ha. Hasil percobaan menunjukkan bahwa dua varietas, yaitu Padi Kuning dan Padi Kutu menghasilkan berturut-turut 4.6 t dan 4,6 t/ha, berbatang tinggi (masing-masing 116,6 cm dan 144,4 cm), dan mudah rebah. Dua varietas yang lain, Ceredek Putih dan Ceredek Merah berturut-turut menghasilkan rata-rata 3,7 t dan 3,3 t/ha, berbatang kuat, tahan rebah, tinggi tanaman termasuk sedang (berturut-turut 103,6 cm dan 107,0 cm), dan umur keduanya 142 hari.
