Abstract

Nematoda puru akar (Meloidogyne spp.) merupakan salah satu patogen penting pada tanaman terung (Solanum melongena L.) yang dapat menurunkan pertumbuhan dan hasil melalui kerusakan sistem perakaran. Pengendalian yang umum dilakukan masih mengandalkan nematisida kimia yang berpotensi menimbulkan dampak negatif terhadap lingkungan, sehingga diperlukan alternatif pengendalian yang ramah lingkungan. Penelitian ini bertujuan untuk mengetahui efektivitas asam amino, Trichoderma sp., dan Bacillus sp., baik secara tunggal maupun kombinasi, dalam menekan serangan Meloidogyne spp. serta pengaruhnya terhadap pertumbuhan dan hasil tanaman terung. Perlakuan terdiri atas kontrol, asam amino, Trichoderma sp., Bacillus sp., kombinasi asam amino + Trichoderma sp., asam amino + Bacillus sp., serta kombinasi asam amino + Trichoderma sp. + Bacillus sp.. Variabel yang diamati meliputi indeks keparahan puru akar, populasi nematoda, tinggi tanaman, jumlah daun, bobot segar dan kering akar, serta berat buah segar. Data dianalisis menggunakan analisis ragam (ANOVA) dan uji lanjut DMRT pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa kombinasi asam amino, Trichoderma sp., dan Bacillus sp. paling efektif dalam menekan keparahan puru akar dan populasi Meloidogyne spp., serta meningkatkan pertumbuhan vegetatif dan hasil tanaman terung.

Kata kunci: Asam amino, Trichoderma sp., Bacillus sp., Meloidogyne spp., Terung
