Agriculture is a major anthropogenic source of the greenhouse gas N2O, which also involved in stratospheric ozone depletion. While use rhizobial inoculants has already been reported as an emerging option for mitigating soil N2O emissions, this study presents situ abatement 70% emission using strain nosZ+ G49 vs. nosZ− USDA138 association with soybean. Therefore, we consider that choice inoculan...

Abstract Purpose (1) To assess the biological N fixation (BNF) potential of varieties faba bean ( Vicia L.) cropped with or without compost in an experimental field-scale rotation no recent history legumes, (2) to enumerate soil populations Rhizobium leguminosarum sv. viciae Rlv ), and genetically characterize nodulating strains, (3) compare BNF other sites Britain. Methods was evaluated from 2...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...

Soybean inoculation with effective rhizobial strains makes unnecessary the use of N-fertilizers in the tropics. A frequently reported problem is the failure of the inoculant strains to overcome the competition imposed by indigenous rhizobial populations. The screening of indigenous rhizobia, already adapted to local conditions, searching for highly effective strains for use as inoculants repres...

abstract now, it’s completely proved that we can find strains among many strains of each rhizobial group that can also do effective process in plant growth promoting as plant growth hormones production (iaa), in addition of their ability in n2 fixation .therefore, the aim of this research is to determinate the ability of iaa production of some of the indigenous rhizobial strains by two quantita...

This study was carried out to determine the effects of actic acid bacterial inoculant on the fermentation and aerobic stability of sunflower silages. Sunflower was harvested at the milk stage. Inoculant-1174 (Pioneer®,USA) was used as homofermentative lactic acid bacterial inoculant. Inoculant was applied 6.00 log10 cfu/g silage levels. Silages with no additive served as controls. After treatme...

Thirty-two bacterial isolates were obtained from root nodules of Lupinus angustifolius growing in Northern Tunisia. Phylogenetic analyses based on recA and gyrB partial gene sequences grouped the strains into six clusters: four clusters belonged to genus Bradyrhizobium (22 isolates), one Microvirga (8 isolates) Devosia (2 a that has not been previously reported nodulate lupin. Representative ea...

Inoculation of legume seed is an efficient and convenient way of introducing effective rhizobia to soil and subsequently the rhizosphere of legumes. However, its full potential is yet to be realised. Following widespread crop failures, the manufacture of high quality inoculants revolutionised legume technology in Australia in the 1960s. Many improvements to inoculants and the advent of an inocu...
