“…In some reports, inoculation with bacteria has promoted seed germination and rate (Ashrafuzzaman et al, 2009;Selvakumar et al, 2009;Zarrin et al, 2009;Noumavo et al, 2013), while in some other reports it has been found to decrease seed germination (Banowetz et al, 2008;McPhail et al, 2010). For example, Selvakuma et al (2009) reported that P. fragi CS11RH1, an IAA-producing strain, significantly increased the germination percentage and rate, plant biomass and nutrient uptake of wheat seedlings.…”

The role of plant-associated bacteria in plant physiology and metabolism is well documented, but little has been known about the roles played by Pseudomonas in durum wheat (Triticum turgidum L. var durum) growth and development. An in vitroexperiment was conducted to observe the effect of the inoculation of four indole-3-acetic acid (IAA)-producing Pseudomonas isolates and exogenous IAA on seed germination traits and α-amylase activity of durum wheat. The results showed inoculation with all bacterial isolates led to a decrease in the germination percent, although the extent of the depression varied with the isolate. A significant relationship between concentrations of bacterial IAA and the germination inhibition percent in durum wheat seeds by different bacteria strains was observed. The results of this assay showed the effect of bacterial isolates on α-amylase activity after six and 8 days of inoculation was significant, while effect of these isolates on α-amylase activity after two and 4 days of inoculation was not meaningful. In addition, the exogenously applied IAA displayed a concentration-dependent effect on seed germination attributes and α-amylase activity, consistent with the possibility that the inhibitory effect of bacterial inoculation on seed germination was in consequence of bacteria-produced IAA. Therefore, it may suggested that the inhibitory role of IAA in seed germination and α-amylase activity should be taken into account during the screening of IAA-producing Pseudomonas isolates for durum wheat growth promoting agents.

“…The use of PGPRs in modern agriculture has been justified in many countries including Brazil, India, America, Argentina and Uruguay (Haghighi et al, 2011). It was well reported that these rhizobacteria are efficient to promote in vitro germination and greenhouse growth of maize (Noumavo et al, 2013).…”

KEYWORDS ABSTRACTThe aim of this study was to assess the combined effects of the three plant growth promoting Rhizobacteria (Azospirillum lipoferum, Pseudomonas fluorescens and Pseudomonas putida) and a biostimulating molecule (chitosan) on plant growth parameters and seeds yield of maize in southern Benin. This study was conducted in reddish ferrous soil with fisher block experimental design. Maize seeds were soaked into chitosan solution for 12 hours and introduced into a seed hole with bacterial suspension. Experimental maize plants were fertilized by half or complete dose of NitrogenPhosphorus-Potassium (NPK) and Urea. Result of the study revealed that the combination of P. fluorescens along with chitosan and half dose of NPK-Urea increased maize height, circumference and seeds yield of 10.18%, 22.05% and 44.10% respectively. Furthermore, the produced biomass increased 71.43% compared to the control in the combination of P. fluorescens, chitosan and complete dose of NPK-Urea. Results of study suggesting that PGPR and chitosan can be used as an effective biological fertilizer combination for increasing maize production under field conditions.

ABSTRAKPenyakit layu Stewart pada tanaman jagung disebabkan oleh bakteri Pantoea stewartii subsp. stewartii, merupakan penyakit penting karena dapat mengakibatkan kehilangan hasil. Di Indonesia, penyakit layu Stewart masih tergolong baru dan belum ditemukan cara pengendaliannya. Penelitian bertujuan untuk mengupayakan pengendalian penyakit layu Stewart menggunakan Rizobakteria yang berperan sebagai PGPR (Plant Growth Promoting Rizobacteria) agar dapat meningkatkan pertumbuhan tanaman jagung sekaligus mengurangi laju perkembangan penyakit layu Stewart. Penelitian berupa percobaan lapangan di dalam polybag menggunakan RAK (Rancangan Acak Kelompok) dengan 11 perlakuan dan 3 ulangan. Sebagai perlakuan adalah beberapa isolat Rizobakteria yang diperlakukan pada benih jagung. Inokulasi patogen P. stewartii subsp. stewartii dilakukan pada bibit jagung umur 7 hst (hari setelah tanam). Parameter pengamatan antara lain: 1) perkembangan penyakit meliputi: periode inkubasi (hari) dan severitas penyakit (%). 2) pertumbuhan tanaman meliputi: tinggi tanaman (cm), diameter batang (mm), jumlah daun (helai), lebar daun ke-7 (cm), panjang daun ke-7 (cm), muncul bunga jantan (hari), muncul bunga betina (hari), berat buah per tanaman (gr), dan diameter buah tanpa kelobot (mm). Hasil penelitian mendapatkan penggunaan Rizobakteria isolat BRb 251 dapat meningkatkan tinggi tanaman, jumlah daun, dan hasil per tanaman jagung. Dengan demikian, berpotensi sebagai PGPR dalam meningkatkan pertumbuhan tanaman jagung, meskipun belum mampu menunjukkan perannya dalam menurunkan laju perkembangan penyakit layu Stewart.Kata kunci : jagung; layu Stewart; laju perkembangan penyakit; pertumbuhan tanaman; Rizobakteria. (plant height (cm), stem diameter (mm) ABSTRACT Stewart's wilt disease in corn plants caused by the bacteria Pantoea stewartii subsp. stewartii, that is important because it can cause yield losses. In Indonesia, Stewart's wilt disease is still relatively new and has not found the way of control. This study aims to seek ways of controlling Stewart's wilt disease by using Rizobakteria which is likely to play a role as PGPR (Plant Growth Promotes Rizobakteria) in order to increase the growth of corn plants while reducing the rate of progression of Stewart's wilt disease. This research trials in polybag using RAK (Group Random Design) with 11 treatments and 3 replications. As a treatment is several isolates rizobactria treat to seedcorn. Bacterial inoculation was performed on the seeds of maize 7 dap (days after planting). The observation parameters were: 1) disease progression (incubation period (day) and severity of disease (%). 2) plant growth
