Pea forms symbiotic nodules with Rhizobium leguminosarum sv. viciae (Rlv). In the field, pea roots can be exposed to multiple compatible Rlv strains. Little is known about the mechanisms underlying the competitiveness for nodulation of Rlv strains and the ability of pea to choose between diverse compatible Rlv strains. The variability of pea-Rlv partner choice was investigated by co-inoculation...
Nitrogen deficit is one of the most limiting nutrients for plant production. Therefore, identifying diazotrophic indigenous inoculants to promote nitrogen fixation have a great importance in agriculture. In the current study, a number of rhizobacteria isolated from nodules of different legumes cultured in Kerman (IRAN) province. Isolates were screened for their ability to grow on N-free media. ...
this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria (pgpr) on dry matter partitioning and some growth parameters of chickpea (cicer arietinum l.) arman cultivar. this research was conducted as split plot based on complete random block design at zanjan university research farm. irrigation levels (optimum irrigation during season gr...
Nitrogen (N) fixation through legume-Rhizobium symbiosis is important for enhancing agricultural productivity and is therefore of great economic interest. Growing evidence indicates that other soil beneficial bacteria can positively affect symbiotic performance of rhizobia. Nodule endophytic plant growth promoting rhizobacteria (PGPR) were isolated from common bean nodules from Nakuru County in...
Root formation and root architecture of olive microshoots, inoculated or not with Pseudomonas fluorescent P19 or P21, were evaluated by measuring of length and the numbers of adventitious and lateral roots. Three-four nodal in vitro shoots were treated with different population densities (0, 105, 108 CFUml-1) of rhizobacteria. The density of 108 CFUmgl-1 induced almost two times increase in num...
The use of organic and biological fertilizers is important for achieving sustainable agriculture, reducing the application of chemical fertilizers and the production of healthy crops. A greenhouse experiment was carried out to study the effects of vermicompost, Nitragin, and nitrogen on some growth parameters of strawberry (Fragariaananassa Duch. cv. Aromas). Treatments were arranged in a facto...
in order to study of the effect of seed inoculation with pgpr on nitrogen and phosphorus use efficiency of spring wheat in different levels of nitrogen and phosphorus fertilizers, an experimental was conducted at the research farm of mohageh ardabili university, ardabil, iran during 2012 year. the combination of nitrogen fertilizer in three levels (0, 40 and 80 kg n/ha as urea) and phosphorus f...
There are increasing applications of diazotrophic rhizobacteria in the sustainable agriculture system. A field experiment on young immature oil palm was conducted to quantify the uptake of N derived from N₂ fixation by the diazotroph Bacillus sphaericus strain UPMB-10, using the ¹⁵N isotope dilution method. Eight months after ¹⁵N application, young immature oil palms that received 67% of standa...
ABSTRACT Although the isolated effects of cyanobacteria Anabaena cylindrica and bacteria Azospirillum brasilense are well-known, co-inoculation both can promote other benefits to corn plants’ biological nitrogen fixation growth. The aim was evaluate initial growth chloroplast pigment levels hybrids co-inoculated with A. cylindrica. experiment conducted in greenhouse conditions using completely ...
