Flavonoids in root exudate of leguminous plants activate the transcription of Rhizobium genes involved in the formation of root nodules (nod genes). We report that inoculation with the homologous symbiont R. leguminosarum bv. viciae results in an increased nod gene-inducing activity (Ini) in root exudate of V. sativa subsp. nigra, whereas inoculation with heterologous Rhizobium strains results ...

BACKGROUND: Azospirillum is effective in biostabilization of nitrogen and Pseudomonas is effective in dissolving soil phosphorus. OBJECTIVES: Current study was conducted to assess effect of different level of nitrogen and biofertilizer on seed yield, its components and protein content. METHODS: This research was carried out via spilt plot fac...

A field experiment was conducted to study the effects of inoculation with the arbuscular mycorrhizal fungus Glomus caledonium and/or Rhizobium meliloti on phytoremediation of an agricultural soil contaminated with weathered PCBs by alfalfa grown for 180 days. Planting alfalfa (P), alfalfa inoculated with G. caledonium (P + AM), alfalfa inoculated with R. meliloti (P + R), and alfalfa co-inocula...

The comparative effect of dual inoculation of native N fixer (Rhizobium) and AM fungi consortia with different organic fertilizers (vermicompost and farm yard manure) on fodder production and quality of two leguminous tree species (Leucaena leucocephala (Lam) de. Wit. and Sesbania sesban (L.) Merr.) in silvopastoral system and their impact on the fodder production of un-inoculated Panicum maxim...

in order to study of effects of integrated biological and chemical  fertilizers on  fertilizer use efficiency, grain yield and related traits to  grain growth of barley (hordeum vulgaris l.), a factorial experiment was conducted based on randomized complete block design with three replications in research farm of the faculty of agriculture sciences, university of mohaghegh ardabili in 2012. tre...

several attributes that make it attractive as a model species. It has a short seed-to-seed generation time and abundant seed set. Extensive collections of M. truncatula ecotypes — natural geographic variants — exist, and mutant collections are readily produced by physical (fast neutron) and transposonmediated mutagenesis. M. truncatula is also host to Sinorhizobium meliloti, a rhizobium species...

Pot and field experiments were done to establish the effect of Rhizobium inoculation, Molybdenum and lime supply on the availability of micronutrients (Cu, Zn, Mn, Fe, B and Mo) in Phaseolus vulgaris L. In both field and pot experiments, Rhizobium inoculation significantly improved uptake of Mn, Fe, Cu, Zn, B and Mo in all organs (roots, shoots, pods and whole plants) except the Mo uptake in ro...

Chemical fertilizers, which contain a nitrogen (N) element, has been intensively used to increase the peanut productivity. However, unstable and high cost of N fertilizer, great demand for fertilizer sources have strongly increased strategical plan fixation (NF). Therefore, field research was carried out appraise ability Rhizobium sp. trains chicken manure (CM) on quality yield peanuts. This fo...

Centrolobium tomentosum is a tropical legume tree indicated for functional and structural restoration of riparian areas. This study was conducted to characterize the rhizobia isolated from nodules of C. tomentosum in situ and to determine their capacity of renodulation, in an experimental area of land rehabilitation in the Rio Doce valley. Nodulation potential to inoculation with 2 selected fas...

Chickpea (Cicer arietinum L.) is the world’s third most vital food legume after beans and peas in production level. Yet, its productivity last decade has been declined, it contended that usual native soil rhizobial populations are insufficient/ineffective N2-fixation. Rhizobium inoculation of seed may substitute costly N-fertilizers provide a useful way achieving sustainable production. Hence, ...
