Abstract

Lahan sawah tadah hujan sebagai lahan yang paling banyak dimanfaatkan untuk pertanaman padi adalah juga merupakan ekosistem yang beresiko tinggi karena sangat mungkin terjadi kekeringan, kebanjiran atau pasang surutnya air laut yang menyebabkan produksi padi pada lahan sawah tadah hujan cenderung rendah. Jumlah bibit perlubang tanam dan umur pindah tanam merupakan beberapa faktor penting yang menentukan keberhasilan dalam kegiatan produksi tanaman padi.Penelitian ini bertujuan untuk mengetahui apakah teradi interaksi antara jumlah bibit dan umur bibit dan untuk mengetahui jumlah bibit dan umur bibit terbaik bagi pertumbuhan dan hasil tanaman padi pada lahan sawah tadah hujan. Penelitian berlokasi di Balai Benih Hortikultura Dinas Pertanian, Perikanan dan Peternakan Kabupaten Sanggau dengan lahan sawah tadah hujan tanah aluvial.Metode yang digunakan adalah Rancangan Acak Kelompok, disusun secara faktorial dan terdiri dari dua faktor yaitu jumlah bibit pertitik tanam (J) terdiri dari 5 taraf 5 bibit pertitik tanam (j1), 10 bibit pertitik tanam (j2), 15 bibit pertitik tanam (j3), 20 bibit pertitik tanam (j4) dan 25 bibit pertitik tanam (j5). Dan umur bibit (U) terdiri dari 14 HSS (u1), 21 HSS (u2), 28 HSS (u3) dan 35 HSS (u4). Variabel pengamatan meliputi tinggi tanaman, jumlah anakan maksimum, jumlah anakan produktif, berat gabah kering panen, berat 1.000 butir gabah, berat gabah kering giling pertanaman, berat gabah kering giling.Hasil penelitian menunjukkan bahwa tidak terdapat interaksi antara perlakuan jumlah bibit dan umur bibit terhadap pertumbuhan dan hasil padi pada lahan sawah tadah hujan. Perlakuan jumlah bibit 5 pertitik tanam dan perlakuan umur bibit 21 HSS merupakan perlakuan terbaik dalam meningkatkan pertumbuhan hasil tanaman padi pada lahan sawah tadah hujan.
