Abstract

The utilization of endophytic bacteria is one of the solutions to control the cocoa black pod rot disease (Phytophthora palmivora Bult) which is environmentally friendly without toxic residues. This study aimed to examine the effectiveness and synergism of several endophytic bacteria from healthy cocoa plants toward inhibit the development of cocoa black pod rot disease. The study used a Randomized Block Design consisting of 11 treatments with a single and mixed application of endophytic bacterial suspension on cocoa pods on trees. Two weeks after application, the cocoa pod was picked from the tree and inoculated with P. palmivora PPKT01 in the laboratory. The inoculated pods were incubated in a plastic box lined with wet tissues to keep the box moist. Disease severity was observed at 3, 5 and 7 days after inoculation. To calculate the AUDPC value, disease suppression index, and synergism between isolates used the results of disease severity observation. The endophytic bacteria inhibited the development of the disease, with effectiveness between 27.31%-55.04%. The mixed treatment of endophytic bacteria Pseudomonas aeruginosa 5BRB3 and Bacillus subtilis 3BAE strains had the lowest disease severity and AUDPC values, making it the most effective and synergistic in inhibiting pod rot disease with a disease suppression index of 55.04%.

Abstract

Tanaman kedelai merupakan sumber protein nabati utama bagi masyarakat Indonesia sehingga memiliki nilai ekonomi yang penting dan strategis. Kebutuhan kedelai Indonesia sebagian besar (60%) masih dipenuhi oleh kedelai import, oleh karena perlu usaha yang keras untuk meningkatkan produktifitas kedelai baik secara intensifikasi maupun ekstensifikasi. Pengenbangan tanaman kedelai di luar Pulau Jawa, termasuk di Sulawesi Tenggara umumnya diusahakan di lahan kering yang tidak difasilitasi dengan irigasi, pada umumnya ditempati oleh tanah yang bereaksi masam, serta miskin hara dan bahan organik dengan kemampuan air yang sangat rendah, sehingga perkembangan perakaran tanaman sangat terbatas dan air hujan cepat hilang dari tanah. Sehubungan dengan hal tersebut, diperlukan suatu teknologi yang dapat memperdalam dan mempelebar jelajah akar serta mampu menyimpan air lebih lama. Teknologi budidaya terpadu yang berbasis biofertilizer dan bahan organik merupakan salah satu teknologi yang dapat dimanfaatkan untuk maksud tersebut. ―BIOFRESH‖ merupakan salah satu produk biofertilizer yang telah dikembangkan di Jurusan Agroteknologi FP-UHO, produk ini berbahan aktif mikroba rizobakteri indigenos tanah ultisol. Penggunaan ―BIOFRESH‖ di tanah ultisol mampu meningkatkan pertumbuhan dan produksi tanaman kedelai, serta meningkatkan ketahanan terhadap penyakit tular tanah. Pemberian biofertilizer Biofresh 10 g pertanaman mampu mengurangi penggunaan pupuk anorganik N,P, dan K sebanyak 40-60%, memiliki efektifitas yang lebih baik dari fungisida mankozeb dalam mengendalikan penyakit busuk batang Rhizoctonia. Penambahan bahan organic sebanyak 2 ton per Ha semakin meningkatkan efektifitas Biofertilizer ―Biofresh‖ dalam meningkatkan pertumbuhan, hasil panen dan ketahanan terhadap penyakit tular tanah.
