Abstract

Perlakuan benih menggunakan rizobakteri sebagai  alternatif  pengganti penggunaan bahan kimia untuk mengendalikan penyakit tanaman. Penelitian ini bertujuan (1) mempelajari  pengaruh beberapa jenis isolat rizobakteri dalam menghambat pertumbuhan Rhizoctonia solani terhadap pertumbuhan bibit tanaman cabai merah, dan (2) pengaruh perlakuan benih menggunakan rizobakteri sebagai pemacu pertumbuhan tanaman. Penelitian ini menggunakan rancangan acak lengkap (RAL) non faktorial. Faktor yang diteliti adalah rizobakteri sebagai agens biokontrol terhadap patogen Rizoctonia solani yang terdiri dari 18 isolat rizobakteri yaitu : Pseudomonas capasia (A1) , Bacillus megaterium (A2), Pseudomonas dimuta (A3), Bacillus bodius (A4), Bacillus laterophorus (A5), Bacillus larvae (A6), Bacillus alvei (A7), Bacillus coagulans (A8), Bacillus firmus (A9), Bacillus pilymixa (A10), Bacillus lichiniformis (A11), Bacillus stearothermophillus (A12), Actinobacillus suis (A13), Actinotorbacter sp. (A14), Azotobacter sp. INA8 (A15), Azotobacter sp. (A16), Necercia sp. (A17), Flavobacterium sp. (A18). Sebagai kontrol (A0) juga dikecambahkan benih yang tidak diberi isolat rizobakteri. Terdapat 6 rizobakteri dari 18 isolat yang diuji yang memberikan penurunan nilai gejala serangan patogen Rhizoctonia solani yaitu Pseudomonas dimuta, Bacillus bodius, Bacillus laterophorus, Bacillus lichiniformis, Bacillus stearothermophillus, dan Azotobacter sp. Perlakuan benih dengan rizobakteri Flavobacterium sp sangat nyata meningkatkan vigor benih pada tolok ukur indeks vigor. Perlakuan benih terbaik dalam meningkatkan pertumbuhan tanaman terhadap parameter tinggi tanaman dan diameter batang umur 4 MSP adalah Bacillus bodius dan parameter jumlah daun pada perlakuan jenis rizobakteri Pseudomonas capasia.Influence of Seed Treatment Using Agens Bio Control Against Rhizoctonia solani Disease and Seedling Growth of Red Chili PepperSeed treatment using rizobakteri as an alternative to substitute the use of chemicals to control plant disease.. This study aims to (1) study the influence of several types of rizobacterial isolates in inhibiting the growth of Rhizoctonia solani on the growth of red chili seedlings, and (2) the influence of seed treatment using rhizobacteria as a trigger for plant growth. This study used a complete randomized design (RAL) non factorial. The factors studied were rizobacteria as a biocontrol agent against Rizoctonia solani pathogen consisting of 18 rizobacterial isolates: Pseudomonas capacia (A1), Bacillus megaterium (A2), Pseudomonas dimuta (A3), Bacillus bodius (A4), Bacillus laterophorus (A5) Bacillus larvae (A6), Bacillus alvei (A7), Bacillus coagulans (A8), Bacillus firmus (A9), Bacillus pilymixa (A10), Bacillus lichiniformis (A11), Bacillus stearothermophillus (A12), Actinobacillus suis (A13), Actinotorbacter sp . (A14), Azotobacter sp. INA8 (A15), Azotobacter sp. (A16), Necercia sp. (A17), Flavobacterium sp. (A18). As control (A0) also added seeds that were not given rizobacterial isolates. There were 6 rhizobacteria of 18 isolates tested which decreased the symptom value of pathogenic attack of Rhizoctonia solani ie Pseudomonas dimuta, Bacillus bodius, Bacillus laterophorus, Bacillus lichiniformis, Bacillus stearothermophillus, and Azotobacter sp. Treatment of seeds with rizobacteria Flavobacterium sp very significantly increases the vigor of seeds on the benchmark vigor index. The best seed treatment in improving plant growth on plant height parameters and stem diameter of 4 MSP was Bacillus bodius and leaf number parameters in the treatment of rhizobacteria Pseudomonas capacia.

Abstract

Abstrak. Penelitian ini bertujuan untuk mengetahui hasil tanaman kedelai akibat aplikasi herbisida oksifluorfen dan pendimethalin. Penelitian ini telah dilaksanakan dari Mei hingga Agustus 2019 di Desa Rumpeet dan Laboratorium Ilmu Gulma, Fakultas Pertanian, Universitas Syiah Kuala. Desain penelitian ini menggunakaan rancangan acak kelompok faktorial 2 x 5 dengan 3 ulangan. Faktor-faktor yang diteliti adalah jenis herbisida yakni terdapat 2 taraf (Oksifluorfen dan Pendimethalin) dan dosis herbisida yakni terdapat 5 taraf (Kontrol, 0,5, 1, 1,5 dan 2 kg b.a ha-1). Adapun hasil penelitian yang dilakukan oleh peneliti membuktikan bahwa jenis herbisida dan dosis herbisida tidak mempengaruhi peubah jumlah polong per tanaman, berat biji per tanaman, berat 100 biji, dan hasil biji kering. Tidak ditemukan interaksi antara kedua faktor tersebut terhadap peubah yang diamati. Saran untuk selanjutnya perlu dilakukan penelitian mengenai berbagai variasi jenis dan dosis herbisida lainnya terhadap hasil kedelai.Characteristics of Soybean Yields Due to Application of Various Dosages of Herbicides oxyfluorphene and pendimethalinAbstract. This research aims to determine the yield of soybean plants due to the application of oxyfluorphene and pendimethalin herbicides. This research was conducted in May to August 2019 in Rumpeet Village and Weed Science Laboratory, Faculty of Agriculture, Syiah Kuala University. The design used was a Randomized Factorial Block Design 2 x 5 with 3 replications. The factors observed were the type of herbicide consisting of 2 levels (Oxyfluorphene and Pendimethalin) and the dosages of the herbicide consisting of 5 levels (Control, 0,5, 1, 1,5 and 2 kg a.i ha-1). The results of research conducted by researchers prove that the type of herbicide and dosage of herbicide does not affect the number of pods per plant, weight of seeds per plant, weight of 100 seeds, and yield of dried seeds. No interaction was found between these two factors with the observed variables. Suggestions for further research needs to be done on a variety of types and dosages of other herbicides on soybean yields.
