Abstract

Varietas lokal dapat berpotensi memilki sifat tahan terhadap cekaman penyakit tungro, sehingga diharapkan mampu meningkatkan keragaan varietas padi yang dibudidayakan baik di lahan sawah maupun lahan rawa. Tujuan penelitian ini adalah untuk mengetahui karakter morfologi dan ketahanan varietas lokal asal Mataram, Toraja, dan Kalimantan Selatan terhadap penyakit tungro. Karakterisasi dilakukan pada 15 varietas lokal dan 5 varietas pembanding, yaitu Ciherang, Utri Merah, TKM6, Situ Patenggang dan Inpari 30. Evaluasi menggunakan varietas tahan wereng hijau (T1-T4) dan tahan tungro (V1-V4). Setiap varietas diamati karakter morfologinya, lalu data yang diperoleh dianalisis dengan aplikasi NTSYS 2.02 untuk memperoleh dendrogram. Kegiatan kedua yaitu evaluasi varietas lokal, masing-masing lima tanaman diinokulasikan wereng hijau. Indeks penyakit dihitung mengikuti panduan SES IRRI, dan keberadaan RTBV dikonfirmasi dengan PCR. Terdapat persamaan pada semua varietas pada karakter warna leher daun, bentuk lidah daun, dan tipe keluar malai yang sempurna. Varietas lokal yang memiliki kemiripan morfologi paling dekat dengan varietas yang disukai petani serta tahan terhadap penyakit tungro dan wereng hijau adalah Siam Kuning dan Karukut, sehingga dapat direkomendasikan tetua perakitan varietas baru tahan tungro. Kata kunci: karakter morfologi, padi tahan tungro, plasma nutfah, uji preferensi

Abstract

Biodecomposers are used as an alternative in pest and weed management by utilizing antagonistic microbes. This study aimed to identify the optimal treatment for suppressing weed growth and controlling the main rice pests, promoting environmentally friendly agricultural practices. Observations were made on three phases of rice growth on land that used biodecomposer and did not use biodecomposer. Weed sampling used a quadrant, which represents each treatment. All weeds were analyzed for density and summed dominance ratio. Pests were observed from the sweep net method. Pests were analyzed with the Shannon-Wiener diversity index (H’). Ten species of weeds are found; the most common and dominant was Cyperus difformis, while the least were Ipomoea aquatica and Ludwigia octovalvis. There were seven pest species; the most common was Nephothettix virescens, while the least was Valanga nigricornis. Using bio-decomposers combined with a two-row planting system was effective in suppressing the development of weeds and pests with a decreasing trend as the rice growing phase increases. Biodecomposers are environmentally friendly even though the process is slow, and have the potential to reduce weeds and pests.Keywords: biodecomposers, Jarwo 2:1, Tegel, trichoderma
