Abstract


Penelitian ini bertujuan untuk menguji pengaruh dosis pupuk organik pada berbagai jarak tanam terhadap pertumbuhan dan hasil padi  . Penelitian ini dilakukan di Desa Tubo Selatan, Sulawesi Barat, menggunakan metode rancangan petak terbagi dengan pola rancangan acak kelompok (RAK) dimana Faktor pertama yaitu Jarak Tanam (J) yang terdiri dari 3 taraf: jarak tanam 22 x 22 cm (J1), 22 x 25 cm (J2), dan 22 x 30 cm (J3). Faktor kedua yaitu pupuk organik (P) yang terdiri dari 3 taraf: Tanpa pupuk (P1), 4 kg pupuk organik (P2) dan 8 kg pupuk organik (P3). Setiap perlakuan diulang sebanyak 3 ulangan, sehingga seluruhnya berjumlah 27 petak. Data dianalisis dengan analisis sidik ragam (anova) pada taraf kepercayaan 95% dengan menggunakan software R-Statistik. Beda nyata tiap perlakuan pupuk organik dan jarak tanam diuji lanjut DMRT. Hasil penelitian menunjukkan bahwa pemberian pupuk organik dosis 8 kg dan jarak tanam 22x30 cm memberikan hasil optimal pada tinggi tanaman walaupun tidak signifikan, sedangkan jumlah anakan, berat gabah basah, berat gabah kering & berat gabah isi menunjukkan signifikan hanya pada perlakuan pupuk organik. Perlakuan kombinasi jarak tanam 22 x 30 cm dan pupuk organik dosis 8 kg mampu meningkatkan efisiensi serapan hara, dengan pengaruh signifikan pada berat gabah isi dibandingkan perlakuan lainnya. Penelitian ini menunjukkan bahwa jarak tanam yang ideal dalam budidaya tanaman padi ialah 22x30 cm dengan dosis pupuk organik terbaik yaitu 8 kg untuk semua variabel yang diamati.
