Abstrak
Produksi padi walik jerami umumnya lebih rendah daripada padi gogorancah di tanah sawah tadah hujan. Rendahnya produksi tersebut diakibatkan oleh cekaman kekeringan yang diderita tanaman saat fase pertumbuhan reproduktif. Suatu penelitian dilaksanakan bertujuan untuk mengetahui pengaruh olah tanah dan pengelolaan air terhadap hasil padi walik jerami di tanah sawah tadah hujan. Percobaan disusun menggunakan rancangan petak terpisah diulang empat kali. Perlakuan terdiri atas pengelolaan air sebagai petak utama dan sistem olah tanah sebagai anak petak. Curah hujan menguntungkan selama pertumbuhan padi walik jerami memberikan hasil gabah tinggi,  akibat tanaman terhindar dari cekaman kekeringan. Sistem olah tanah dan pengelolaan air tidak nyata mempengaruhi hasil gabah padi IR64, dengan hasil gabah rata-rata 4,10 t/ha. Olah tanah dangkal atau normal nyata menurunkan bobot isi  saat fase pertumbuhan anakan maksimum.

Kata kunci : padi walik jerami, olah tanah, pengelolaan air


Abstract

Improving Productivity of Transplanted Rice Crop Through Soil Tillage Method and Water Management. Transplanted rice production is commonly lower than direct seeded rice in rainfed lowland ecosystem. Such low production is affected by drought stress which is suffered rice crop at reproductive stage. A field experiment was conducted to understand the effect of soil tillage method and water management on yield of transplanted rice in rainfed lowland rice soil. The experiment was designed using split plot replicated four times. The treatments consisted of water management as main plot and soil tillage method as subplot. The advantegous rainfall during growing transplanted rice gave high grain yield, because of no drought stress. Soil tillage method and water management did not affect significantly grain yield of IR64, average yield obtained was 4.10 t /ha. The shallow soil tillage reduced significantly bulk density, especially at maximum tillering stage.


Keywords : transplanted rice, soil tillage, water management.
