According to Statistics Canada, the cropping area for field pea (Pisum sativa) in Western Canada has increased from 25 000 ha in 1976 to 1 335 000 ha in 2001. As part of the production system, field peas require inoculation with Rhizobium leguminosarum bv. Viceae, particularly, when grown for the first time in rotation. Appropriate rhizobial inoculation and fertility management can increase fie...

The reduction of chemical inputs due to fertilizer and pesticide applications is a target shared both by farmers consumers in order minimize the side effects for human environmental health. Among possible strategies, use biostimulants has become increasingly important as demonstrated fast growth their global market increased rate registration new products. In this work, we assessed five bacteri...

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...

Seed inoculation with bacterial consortium was found to increase legume yield, providing a higher growth than the standard nitrogen treatment methods. Alfalfa plants were inoculated by mono- and binary compositions of nitrogen-fixing microorganisms. Their physiological and biochemical properties were estimated. Inoculation by microbial consortium of Sinorhizobium meliloti T17 together with a ne...

to survey the effects of flooding during the reproductive growth stages of aerenchyma formation and ethylene production in soybean cultivar dpx experiment  the completely randomized factorial was in 2012 in gorgan university of agricultural sciences and natural resources. factors examined include nutrition levels in three levels (1 - inoculated with bacteria japonicumbradyrhizobium 2 - non-inoc...

in order to evaluate effect of azotobacter chroococcum strains on yield, yield components and qualitative indices of winter rapeseed (brassica napus l.), an experiment was conducted during 2009-2010 growing season at research institute of rice in rasht. the experimental design was completely randomized block, with three replications. investigated treatments were including control (without seed ...

Background: Effectiveness of Rhizobium inoculation is determined by common bean genotypes. Environmental factors also affect common bean genotypes-Rhizobium-symbiosis. The effect of common bean genotypes-Rhizobium strains-environment interaction on nodulation and common bean production is not well studied. Three genotypes (Dursitu, Gofta, and Kufanzik) and eight selected isolates of common bean...

In 56-day-old plants, Leucaena leucocephala and its hybrid with L. diversifolia showed 100% more total N than did L. diversifolia. Significant (P < 0.01) host-inoculation interaction in total N was 14.4% of the total phenotypic variation. The most effective and competitive Rhizobium sp. for the leucaenas was TAL 1145. Three-strain mixed inoculation was inferior to TAL 1145 alone.

Nodule bacteria (rhizobia) in symbiotic associations with legumes enable considerable entries of biologically fixed nitrogen into soil. Efforts are therefore made to intensify the natural process of symbiotic nitrogen fixation by legume inoculation. Studies of field populations of rhizobia open up the possibility to preserve and probably exploit some indigenous strains with hidden symbiotic or ...
