Zahra, Sarah Lail (2019) Pengaruh Plant Growth Promoting Rhizobacteria (PGPR) terhadap Infeksi Cowpea Mild Mottle Virus (CPMMV), Pertumbuhan dan Produksi Tanaman Kedelai (Glycine Max (L.) Merrill) Varietas Argomulyo. Sarjana thesis, Universitas Brawijaya.
Abstract
Kedelai merupakan bahan baku berbagai produk di Indonesia, mulai dari makanan hingga merambah pada farmasi dan kosmetik. Ketersediaan kedelai merupakan hal yang menjadi pusat perhatian bagi petani dan produsen demi memenuhi kebutuhan pasar yang cenderung terus naik. Cowpea Mild Mottle Virus atau CPMMV tercatat sebagai salah satu virus penting di tanaman kedelai yang keberadaannya dapat menurunkan produksi serta kualitas hasil panen. Penelitian kali inii ditujukan untuk mengetahui respon tanaman kedelai varietas Argomulyo yang dikenal sebagai salah satu varietas rentan CPMMV namun keberadaannya dibutuhkan oleh produsen berbagai produk makanan, beberapa diantaranya adalah susu, kecap, dan tempe, pengendalian dilakukan dengan pengaplikasian Plant Growth Promoting Rhizobacteria (PGPR) di awal tanam sebagai tindakan preventif sebelum tanam. Terdapat 8 perlakuan dan 4 kali ulangan yang masing masing perlakuan adalah perlakuan tunggal dan kombinasi yakni P0+ : Kontrol positif (tanpa perlakuan PGPR, inokulasi CPMMV), P0-: Kontrol negatif (tanpa perlakuan PGPR, tanpa inokulasi CPMMV), P1: Aplikasi PGPR P. fluorescens, P2: Aplikasi PGPR Azotobacter sp., P3: Aplikasi PGPR B. subtilis , P4: Aplikasi PGPR P. fluorescens dan PGPR Azotobacter sp., P5: Aplikasi PGPR P. fluorescens dan PGPR B. subtilis, P6: Aplikasi PGPR Azotobacter sp. dan PGPR B. subtilis. Penelitian dilakukan dengan rancangan acak kelompok kemudian dilanjutkan dengan uji DMRT 5% apabila hasil perhitungan menunjukkan hasil yang berbeda nyata. Hasil menunjukkan perlakuan tunggal terbaik bagi masa inkubasi dan intensitas serangan CPMMV terdapat pada perlakuan tunggal Azetobacter, sedangkan perlakuan terbaik untuk fase vegetatif dan produksi tanaman kedelai varietas argomulyo terdapat pada perlakuan kombinasi Pseudomonas fluorescent dan Bacillus subtilis
English Abstract
Soybean is a raw material of various products in Indonesia, ranging from food and spread to pharmaceuticals and cosmetics. The availability of soy is the center of attention for farmers and producers to meet the needs of the market that tends to go up. Cowpea mild mottle virus or CPMMV is recorded as one of the important viruses in soybean plants that its existence can decrease production and quality of crop yields. This research is aimed to know the response of soybean varieties of Argomulyo variety that known as one of the vulnerable varieties for CPMMV but its existence is needed by producers of various food products, some of which are milk, soy sauce, and tempeh, the control is done with the application of Plant Growth Promoting Rhizobacteria (PGPR) in the early planting as a preventive action before planting. There are 8 treatments and 4 times the repetition of each treatment is the single treatment and combination of P0 +: Positive control (without PGPR treatment, CPMMV inoculation), P0-: Negative control (without PGPR treatment, without CPMMV inoculation), P1: PGPR application P. Fluorescens, P2: Application PGPR Azotobacter sp., P3: Application PGPR B. subtilis, P4: Application PGPR P. Fluorescens and PGPR Azotobacter sp., P5: Applications PGPR P. Fluorescens and PGPR B. subtilis, P6: Application PGPR Azotobacter sp. and PGPR B. subtilis. The research was conducted by the group's random design and then continued with a 5% DMRT test when the calculation results showed a distinct real result. The results show the best single treatment for the incubation period and intensity of the CPMMV attacks present in the single treatment of Azetobacter, while the best treatment for plant phase and soybean production of varieties of Argomulyo are found in Combination treatment Pseudomonas fluorescent and Bacillus subtilis
