Abstract

Sistem tanam (ST) yang sering digunakan petani yaitu ST tegel. Sampai sekarang masih banyak petani yang menggunakan bibit lebih dari tujuh batang per lubang tanam (BpLT). Tujuan penelitian adalah untuk mempelajari respon tanaman padi terhadap  ST dan jumlah bibit per lubang tanam (JBpLT). Penelitian dilakukan di Desa Raman Aji, Kecamatan Raman Utara, Lampung Timur pada bulan Februari sampai Mei 2016.  Perlakuan disusun dalam Rancangan Kelompok Teracak Lengkap dengan pola split plot.  Petak utama adalah ST jarwo 2:1, ST Jarwo 4:1, dan ST tegel 25 x 25 cm. Anak petak terdiri atas JBpLT: 1 BpLT, 2 BpLT, dan 3 BpLT. Data dianalisis ragam dan dilanjutkan uji orthogonal  kontras, semua pengujian dilakukan pada taraf 5%.  Hasil percobaan menunjukkan bahwa (1) ST jarwo 2:1 dan ST jarwo 4:1 meningkatkan pertumbuhan padi hibrida Mapan P-05 dibandingkan ST tegel 25 x 25 cm, (2) penanaman 1 BpLT meningkatkan komponen hasil padi dibandingkan penanaman 2 BpLT dan 3 BpLT, dan (3) penanaman 1 BpLT memberikan hasil GKG (6,86 t ha-1) yang lebih tinggi dari penanaman 2 BpLT (5,64 t ha-1) dan 3 BpLT (4,59 t ha-1) pada ST jarwo 2:1, ST jarwo 4:1 dan ST tegel 25 x 25 cm, secara berurutan.

Abstract

The common planting system (PS) used by the farmers is Tegel system. Yet, many farmers still use more than seven seeds per planting hole (SpPH). The research objective was to study the reponse of rice plants to the planting system and the number SpPH. The research was conducted in Raman Aji Village, Raman Utara, East Lampung from February to May 2016. The treatments were arranged in a RCBD with a split plot pattern (the main plot were the PS i.e. jarwo 2: 1, jarwo 4: 1 and “Tegel†25 x 25 cm; the subplots are the number of SpPH i.e. 1 SpPH, 2 SpPH, and 3 SpPH). The results showed that (1) the jarwo 2: 1 system increased rice growth compared to the 25 x 25 cm “Tegelâ€; (2) application of 1 SpPH increased the yield  component  of rice compared to planting 2 SpPH and SpPH; and (3) application of 1 SpPH (6.86 t ha-1) gave the higher weight of milled grain than using 2 SpPH (5.64 t ha-1) and 3 SpPH (4.59 t ha-1), both planted in the jarwo 2:1, jarwo 4:1 and 25 x 25 cm  “Tegel†System
