Aphis Glycines Matsumura

Plant Growth Promoting Rhizobacteria (PGPR) applied to different plants may suppress pests population developments. This research was to study the capability of a commercial PGPR product contained Bacillus polymyxa and Pseudomonas fluorescens in suppressing population developments of Aphis glycines Matsumura (Hemiptera: Aphididae). The biology and demographic statistics of A. glycines reared on soybean with and without the PGPR applications were compared. The PGPR suspensions of 5 g formulation per liter water were used to soak soybean seed for 15 minutes and to water soybean plant 2 weeks after transplanting. Cohorts of 65 first instar A. glycines of each treatment were observed daily and individual mortality, molting, and fecundity were recorded until the last individual dead. Second instar stadium of A. glycines reared on treated plant lasted longer than those reared on untreated plant, i.e. 1.4 and 1.1 days, respectively. These resulted on a longer life cycle for A. glycines reared on treated plant than on untreated plant, i.e. 4.9 and 4.5 days, respectively. In turn, it caused the A. glycines population to experienceslower growth on treated plants than on untreated plants.  The values of A. glycines GRR, Ro, rm, T and DT on treated plants were 71.834, 57.780, 0.557, 7.287 and 1.245, consecutively; whilst that of untreated plants were 104.861, 63.326, 0.586, 7.084 and 1.184, respectively.

Mikroba Bacillus subtilis merupakan agen pengendali hayati mempunyai kelebihan sebagai Plant Growth Promoting Rhizobacteria (PGPR) yaitu dapat berfungsi sebagai biofertilizer, biostimulan, biodekomposer dan bioprotektan. Tujuan penelitian mengetahui potensi B. subtilis dalam merombak bahan organik sebagai usaha meningkatkan ketersediaan bahan organik tanah yang semakin menurun. Penelitian menggunakan Rancangan Petak Terbagi dengan berbagai  bahan organik sebagai petak utama (B0 = tanpa bahan organik, B1 = kotoran ayam,  B2 = kotoran kambing, B3 = kotoran sapi) dan aplikasi B.subtilis sebagai anak petak (A0 = 0 cc/L, A1 = 5cc/L, A2 = 10 cc/L, Pengamatan meliputi variabel tinggi tanaman, indeks luas daun, jumlah buah per tanaman, berat buah per tanaman, dan bahan organik tanah. Data pengamatan  dianalisis ragam  menggunakan  Statistical Product and Service Solutions (SPSS) versi 25 dan dilanjutkan dengan uji Duncan untuk mengetahui signifikansi perbedaan antar perlakuan. Hasil penelitian menunjukkan tidak terdapat interaksi antara bahan organik kotoran ternak dan konsentrasi B. subtilis terhadap semua variabel pengamatan. Potensi B. subtilis sangat baik dalam mendekomposisi bahan organik yang ditunjukkan dengan peningkatan bahan organik, dan hasil terbaik pada kotoran  sapi (B3) dan konsentrasi B. subtilis 15 mL/L masing-masing sebesar 46.47 % dan 34.76 %. Variabel pertumbuhan tidak berbeda nyata kecuali tinggi tanaman dengan pertambahan tinggi paling banyak pada pemberian kotoran kambing sebesar 170.69 %.

Biofertilizers are fertilizers containing microorganisms that promote plant growth by improving the supply of nutrients to the host plant. The supply of nutrients is improved naturally by nitrogen fixation and solubilizing phosphorus. The living microorganisms in biofertilizers help in building organic matter in the soil and restoring the natural nutrient cycle. Biofertilizers can be grouped into Nitrogen-fixing biofertilizers, Phosphorous-solubilizing biofertilizers, Phosphorous-mobilizing biofertilizers, Biofertilizers for micro nutrients and Plant growth promoting rhizobacteria. This study conducted in Kottayam district was intended to identify the awareness and acceptance of biofertilizers among the farmers of the area. Data have been collected from 120 farmers by direct interviews with structured questionnaire.
