Pengaruh Isolat Rizobakteri Indigeneous KNW11 dan Pemupukan terhadap Pertumbuhan dan Hasil Padi Gogo Lokal Wakawondu
Abstract
Rendahnya produktivitas padi gogo lokal masih menjadi tantangan. Tujuan penelitian yaitu mengetahui efektivitas rizobakteri KNW11 dan pemupukan terhadap produktivitas padi gogo lokal Wakawondu. Penelitian ini berlangsung mulai Agustus 2020-Januari 2021 di lahan percobaan Fakultas Pertanian UHO Kendari. Rancangan perlakuan yaitu petak terpisah dalam RAK. Perlakuan Rizobakteri (S) sebagai petak utama, terdapat 2 taraf yaitu tanpa Rizobakteri (R0) dan isolat KNW11 (R1). Pupuk (P) sebagai anak petak, terdapat 4 taraf yaitu tanpa pemberian pupuk (P0); 100% bokashi kirinyuh atau 10 ton per hektar (P1); 100% urea, SP-36, KCl atau 200 kg urea, 100 kg SP-36 dan 100 kg KCl per hektar (P2); dan Kombinasi 50% bokashi kirinyuh, urea, SP-36, KCl atau 5 ton bokashi kirinyuh, 100 kg urea, 50 kg SP-36 dan 50 kg KCl per hektar (P3). Setiap unit percobaan diulang 3 kali. Perlakuan rizobakteri dan pupuk meningkatkan produktivitas padi gogo lokal Wakawondu. Interaksi rizobakteri KNW11 dan pupuk anorganik meningkatkan jumlah anakan sebesar 49.5% dibandingkan kontrol. Perlakuan rizobakteri KNW11 menghasilkan bobot gabah per hektar 1.95 ton atau meningkat 15.4% dibandingkan kontrol. Perlakuan 50% pupuk organik dan 50% pupuk anorganik menghasilkan gabah per hektar tertinggi yaitu 2.38 ton atau meningkat sebesar 59.2% dibandingkan kontrol.
