Research ArticleOpen accessEvery word in the titleEfficiency of Nitrogen Fixation by Rhizobium Strains Associated With White Clover in the Ecuadorian Highlands Biological Nitrogen Fixation by White Clover in EcuadorDaniela Michell Chuquimarca Mamarandi, Venancio Saúl Arahana Bonilla, Paulina Andrea Cevallos Hidalgo et al.The objective of this research was to evaluate the nitrogen-fixing capacity of 30 strains of Rhizobium isolated from white clover nodules, collected in the provinces of Pichincha and Cotopaxi under greenhouse conditions. After isolation of the bacteria and authentication of the isolates, a greenhouse experiment was conducted, in a Completely Randomized Design (CRD), with three replications and two controls: with … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 4 Oct 2026 · 835 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEnhanced Survival and Nodule Occupancy of Pigeon pea Nodulating Rhizobium sp. ST1 expressing fegA Gene of Bradyrhizobium japonicum 61A152Falguni R. Joshi, Dhwani K. Desai, G. Archana, Anjana J. DesaiProblem statement: Rhizobial isolates belonging to genera (Rhizobium sp. and Mesorhizobium sp.) in our laboratory produced only catecholate type of siderophores. Although FhuA and FegA (ferrichrome receptors) homologs were found to be present in the sequenced genomes of few rhizobia (e.g., 1 in R. etli and 2 in Mesorhizobium sp. BNC1), laboratory isolates of the corresponding genera failed to utilize … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,865 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffects of Bradyrhizobium Japonicum on Nitrogen Concentration in Soybean Leaves and Seeds Cultivated on Acidic SoilsBen Tshibuyi Kasu-Bandi, Fabien Kitengie Kitengie, Jonas Lwamuguma Bagaluza et al.The legume-rhizobium symbiosis plays an important role in Nitrogen (N) uptake by plants, more particularly in the humid tropical region where soils are deeply weathered and have poor electrochemical properties. However, the influence of Bradyrhizobium on N allocation in soybean organs is not clearly understood. Here, we assessed the effect of Bradyrhizobium japonicum on the N concentration of soybean leaves … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 24 Jan 2022 · 7,663 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsResponse of Root Properties to Tripartite Symbiosis between Lucerne (Medicago sativa L.), Rhizobia and Mycorrhiza Under Dry Organic Farming ConditionsM. R. Ardakani, G. Pietsch, A. Moghaddam et al.Problem statement: It is generally considered that root turnover is a major contributor to organic matter and mineral nutrient cycles in organic managed agroecosystems. Approach: This study designed to investigate whether microbial activity could affect on root properties of Lucerne in an organically managed field under dry weather conditions. The trial was laid out as a factorial experiment in the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,504 accessesView PDF Cite

Research ArticleOpen accessIn the abstractISOLATION AND CHARACTERIZATION OF RHIZOBIA AND PLANT GROWTH-PROMOTING RHIZOBACTERIA AND THEIR EFFECTS ON GROWTH OF RICE SEEDLINGSK. Z. Tan, O. Radziah, M. S. Halimi et al.Biofertilizer is a relatively safer, environmentally friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Due to aforementioned interest, several Plant Growth-Promoting Rhizobacterial (PGPR) and rhizobial strains were isolated from rice and legume roots, respectively, at four locations … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 15 Apr 2014 · 10,904 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Ecological Survey of Microorganisms Associated with Plantain Roots (Rhizosphere)Bello O.S., G.A. UtangProblem statement: Micro-organisms are more predominant around root zone and as such play a vital role to plant. Micro-organisms are diverse and have property modification which are beneficial to plant growth and root development. Approach: The lack of knowledge on the specific microorganisms associated with plantain roots in Cross River State soils (which inturn leads to an avoidable loss of … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 31 Dec 2011 · 8,268 accessesView PDF Cite
