“…Such results were comparable to those obtained by Passos et al (2014) who also did not achieve any statistically significant results in terms of the root's dry mass when they inoculated apple seedlings with five bacterial isolates from the rhizosphere. Dawwam et al (2013) observed an increase in nitrogen (50.5%) and phosphorus content (48.3%) in the Ipomoea batatas L.'s dry mass when compared to the control group; increases that were also observed in this study with respect to carbon (10% to 14%) and nitrogen (61.7% to 140%) contents. Passos et al (2014) analyzed apple seedlings in terms of absorption of nitrogen, phosphorus and potassium, and determined that only plants inoculated with Burkholderia sp.…”

“…According to Dobbelaere, Vanderleyden, and Okon (2003) the ability to synthesize phytohormones is widespread among bacteria associated with plants, and these hormones stimulate plant growth and promote an increase in root area, allowing for better nutrient absorption from the soil. In yet another study, Dawwam et al (2013) verified that all seven bacteria isolated from the Ipomoea batatas L. rhizosphere produced IAA with concentrations ranging from 0.6 µg·mL -1 to 10.73 µg·mL -1 ; in this study, for which IAA concentrations ranged from 0.36 mg·mL -1 a 14.77 mg·mL -1…”

Although several studies have reported the potential of different microorganisms to promote growth in plants such as wheat, soybeans, and potatoes, these are in short supply for the cultivation of grapevines, both in terms of the isolation of the microorganisms and when it comes to in vitro and in vivo testing (Dawwam, Elbeltagia, Emara, Abbas, & Hassan, 2013;Karagöz, Ates, Karagöz, Kotan, & Cakmakci, 2012;Smyth et al, 2011;Khalid, Arshad, & Zahir, 2004). In the last couple of decades, research efforts related to the development of biological consumables, such as inoculating agents, have mustered a lot of attention from researchers.…”

Certain bacteria can promote and stimulate plant growth, increasing the production of biomass and reducing damage caused by phytopathogens. With that in mind, this research effort set out to select these plant growth-promoting bacteria in order to evaluate their effects on the growth of grapevines (Vitis sp.). The bacteria were isolated from several vineyard soil samples, and evaluated based on their production of IAA (Indole-3-Acetic Acid), siderophores and cellulase, as well as their phosphate solubilization and nitrogen fixation capabilities. In vivo testing included six separate treatments with the following bacterial isolates: C12, O7, B3, I3, a control group and a blended group. The tests were performed in a greenhouse with bacterial suspension inoculation placed around the roots of Paulsen 1103 rootstock cuttings. The data collected included the following: number of leaves per plant, branch lengths, chlorophyll content, fresh and dry mass, and Carbon, Hydrogen, Nitrogen and Sulfur concentrations. Forty-six separate bacteria were isolated, of which 100% produced IAA, 65.21% produced siderophores, 63.04% solubilized phosphate, 34.78% produced cellulase, and 30.43% showed nitrogen fixation. The in vivo testing also revealed significant increases in the length of the branch and in percentages of Carbon and Nitrogen. The C12 isolate exhibited the highest increase in branch length (76.704 cm), whereas the O7 and C12 were identified as Bacillus amyloliquefaciens and Bacillus thuringiensis, respectively.

“…Work by Dawwam et al (2013) recommended B. cereus isolated from roots of potato plant as a biofertilizer component due to its excellent plant growth promoting characteristics. In addition, Zhao et al (2011) also classified B. cereus isolated from Sophora alopecuroides root nodules as a potent plant growth promoter.…”

Antagonistic Efficacy of Trichoderma harzianum and Bacillus cereus against Ganoderma Disease of Oil Palm via Dip, Place and Drench (DPD) Artificial Inoculation Technique

Sustainability of the oil palm industry is crucial to ensure Malaysia's gross domestic product (GDP) by the agricultural sector. It is crucial to discover a sustainable and eco-friendly remedy for the most devastating Ganoderma disease of oil palm. The effects of pre-inoculation of oil palm seedlings with either Trichoderma harzianum and/or Bacillus cereus on their vegetative growth and the suppression of Ganoderma boninense were investigated. The dip, place and drench (DPD) artificial inoculation method was used to assure disease development. Disease severity was assessed based on the root symptoms (DS), disease incidence (DI) and disease reduction (DR). Application of a mixture of T. harzianum and B. cereus had the highest contribution to the vegetative growth of oil palm seedlings. However, single application of B. cereus was found to be the most effective treatment in suppressing Ganoderma disease of oil palm with a disease reduction of 94.75% followed by single applications of T. harzianum (78.98%) and mixture of both T. harzianum and B. cereus (68.49%).

“…Silicate dissolving bacteria play an important role in the formation of humus in soil, the cycling of other minerals tied up in organic matter (Zakaria, 2009). Also, it can be able to solubilize rock -K mineral powder, such as mica, illite and orthoclases (feldspar), through production and excretion of organic acids or chelate silicon ions to bring K into solution (Ullman et al, 1996, Badr et al, 2006, Eweda et al, 2007, Abou-el-Seoud & Abdel-Megeed, 2012and Dawwam et al , 2013.…”

SOIL potassium content is a limiting factor of wheat growth and productivity, as it is one of the most important major elements for plant growth. The Need for optimizing use of potassium fertilization using natural amendments is growing up parallel with the accelerating increase in fertilizer prices. A field experiment was carried out during 2014-2015 growing season in Salehia, Egypt. The aim of the study is to investigate the effect of different sources of potassium fertilizers (potassium sulphate and potassium feldspar) at the recommended rate (95 kg K ha -1 ) and either single or in combination with organic amendments ,i.e. chicken manure (Ch.M) and farmyard manure (FYM) with silicate dissolving bacteria (SDB) on yield and nutrients uptake by wheat. The results indicated that the highest values of dry matter yield of wheat, biological yield, protein content, NPK -uptake and available potassium in soil were observed at the treatment of (K sulphate or K-feldspar + Ch.M) in the presence of SDB. Dry matter yield of straw and grain ranged from 8.53 to 11.79 and 5.94 to 8.11 Mg ha -1 , respectively. Based on thesa results, the available potassium was remarkably increased after 60 and 90 days and then decreased at 150 days at all treatments for application of potassium sources and organic amendments with SDB.
