Abstract

Bakteri pelarut fosfat Paenibacillus alvei selain mampu melarutkan fospat, juga membentuk indole acetic acid (IAA) dan siderofor, serta berperan sebagai biokontrol. Penyakit hawar pelepah padi disebabkan oleh jamur Rhizoctonia solani Kuhn. Penyakit ini mudah ditemukan pada setiap musim tanam, sehingga sulit dikendaliakn. Penelitian ini bertujuan untuk mengevaluasi ketahanan padi Ciherang Merah yang diberi perlakuan isolat BPF terhadap serangan R. solani pada kondisi tanah sulfat masam. Penelitian dirancang, menggunakan rancangan acak lengkap dengan 4 taraf perlakuan berupa isolat BPF isolat 4A (P1), 6A (P2), konsorsium 4A dan 6A (P3), dan kontrol (P4). Setiap perlakuan terdiri dari 5 ulangan. Pengamatan dilakukan setiap minggu hingga padi berumur 7 MST. Variabel yang diamati meliputi tinggi tanaman, jumlah daun, jumlah anakan, berat basah tanaman, berat basah akar, berat kering tanaman, berat kering akar, insidensi serangan, keparahan penyakit, kemampuan bakteri uji menekan keparahan penyakit, dan tingkat ketahanan tanaman terhadap penyakit. Hasil pengujian menunjukkan bahwa pemanfaatan BPF dalam mengendalikan penyakit hawar pelepah pada padi Ciherang Merah memiliki tingkat ketahanan yang berbeda jika dibandingkan dengan kontrol yang tergolong rentan. BPF isolat 6A, dan konsorsium 4A dan 6A tergolong tahan, serta BPF isolat 4A agak rentan terhadap penyakit hawar pelepah. Kerusakan tanaman berbanding terbalik dengan perkembangan insidensi serangan yang cenderung terus meningkat, karena perlakuan pemberian BPF menekan keparahan penyakit dan memicu pertumbuhan padi Ciherang Merah di tanah sulfat masam.Kata Kunci: Paenibacillus alvei,  Hawar  Pelepah  Padi,  Padi Ciherang Merah, Biokontrol

Abstract

The West Kalimantan land is mostly dominated by marginal peat land types. The West Kalimantan peat swamp land has a very low pH, low nutrient availability, low base saturation, high nutrient washing rates, and even some of them are sandy soil which is in the lower layers. One way to utilize peat marginal land as an agricultural crop is by utilizing Arbuscular Mycorrhizal Fungi (FMA) as biological fertilizer inoculums. The stages of the research are the exploration of FMA from several root zone plants from two locations, Galang and Rasau Jaya Villages, then identification of FMA in the plant disease laboratory of Tanjungpura University's Faculty of Agriculture. The study was carried out for ± 3 months. The design used is by using purposive sampling method, with the number of sample points on three commodities, namely pineapple, fern and grass, each of 9 sample points. The results showed an analysis of the content of the number of FMA spores found in the highest root rooting zone found in the source of pineapple inoculums, with the number of FMA spores found as many as 96, with soil samples each of 50 g samples. Whereas the fern media amounted to 55, and the grass media amounted to 22. The highest level of FMA diversity was found in the treatment with the source of pineapple inoculum from Galang, with the discovery of three types of FMA namely genus Glomus sp, Gigaspora sp and Acaulospora sp. Keywords: arbuscular mycorrhizal fungi (AMF), exploration, marginal peat soi
