Abstract

Layu fusarium merupakan salah satu penyakit penting di pertanaman tomat, termasuk di lahan Ultisol di Sulawesi Tenggara. Rizobakteri pemacu pertumbuhan tanaman merupakan salah satu alternatif pengendalian penyakit yang menjanjikan untuk mengatasi masalah layu fusarium. Penelitian bertujuan mengetahui keefektifan formulasi rizobakteri indigenus untuk mengendalikan layu fusarium dan meningkatkan hasil panen tanaman tomat di tanah Ultisol. Penelitian dilaksanakan di Laboratorium Agroteknologi dan Rumah Kasa, Fakultas Pertanian, Universitas Halu Oleo dari Bulan Oktober 2010 sampai Januari 2011. Penelitian disusun berdasarkan rancangan acak lengkap dengan tujuh perlakuan, yaitu (RB) aplikasi rizobakteri pada benih, (RB.2) aplikasi rizobakteri pada benih dan pada tanaman 2 minggu setelah tanam, (RB.2.4) aplikasi rizobakteri pada benih dan pada tanaman 2 dan 4 minggu setelah tanam, (RBF.2) aplikasi rizobakteri pada benih dan aplikasi fungisida sintetik pada tanaman 2 minggu setelah tanam, (FB.4) aplikasi fungisida sintetik pada benih dan pada tanaman 2 minggu setelah tanam, (FB.2.4) aplikasi fungisida sintetik pada benih dan pada tanaman 2 dan 4 minggu setelah tanam, serta kontrol. Semua perlakuan diinokulasi dengan Fusarium oxysporum f. sp. lycopersici dan diulang tiga kali. Hasil penelitian menunjukkan bahwa perlakuan rizobakteri pada benih yang disusul pada saat 2 dan 4 minggu setelah tanam paling efektif mengendalikan layu fusarium dengan penekanan sebesar 61,14%, serta mampu meningkatkan hasil tanaman dengan jumlah buah 10,88 dan bobot buah 375,31 g per tanaman, sedangkan tanaman tanpa perlakuan tidak berproduksi. Hasil ini mengindikasikan bahwa formulasi rizobakteri indigenus mampu mengendalikan layu fusarium dan meningkatkan hasil panen tanaman tomat di tanah Ultisol.

Abstract

Foot rot disease of black pepper caused by Phytophthora capsici is the most destructive disease in Southeast Sulawesi. The disease intensity is 61.2%. This disease is difficult to control because the pathogen is soil borne and influenced by various complex environmental conditions. The study aimed to determine the correlation of physical and chemical soil characteristics with disease intensity of foot rot of black pepper. Disease intensity was assessed from the subplots of black pepper plantation of 15x15 m2 consisting of 36-40 plants. Soil samples were randomly taken from the rhizosphere of the plants in each sub plot, mixed and taken as a composite. The physical and chemical analyses were conducted in the laboratory of Physics and Chemistry of the Faculty of Agriculture, Gajah Mada University. Disease intensity and soil characteristics were analyzed its correlation using a path analysis. The results showed that soil fertility in the study area was low. The path analyses indicated that physical and chemical properties that correlated with low disease intensity were high cation exchange capacity (CEC), base saturation (BS), potassium and phosphor available as well as moisture at field capacity, whereas those induced disease development were high content of clay fraction, sand fraction, porosity, total N, C-organic and salinity. The control strategy for foot rot disease in Southeast Sulawesi was possibly by increasing CEC, BS, potassium and phosphor available, as well as by improvement of soil texture that can lower high fraction of clay, sand and soil porosity
