abstract nickel is a heavy metal distributed ubiquitously in nature. it accumulates in soil as a result of human activities, including mining and industries development. it may be poisonous to plants, humans, animals and microorganisms. the present study was implemented as a factorial experiment with a randomized complete block design (rcbd), of three replications in calcareous soils of karaj a...

Bacterial biocontrol strains used as an alternative to chemical fungicides may influence bacterial communities in the rhizosphere and effects might differ depending on the soil type. Here we present baseline data on the effects of Pseudomonas jessenii RU47 on the bacterial community composition in the rhizosphere of lettuce grown in diluvial sand, alluvial loam and loess loam at the same field ...

Four experiments were carried out in Lelystad, The Netherlands in 1994, in which perennial ryegrass wilted to 421–568 g dry matter (DM) kg−" was ensiled with and without an inoculant containing Lactobacillus plantarum and Enterococcus faecium strains in 1-litre capacity laboratory silos. Treated silages showed a markedly increased rate of pH decline. The final pH of treated silages was reached ...

In the resent study, a diazotrophic bacterial isolate JPA2 having the ability to tolerate salinity (6 % NaCl) and plant growth-promoting features was isolated from rhizospheric soil of weed Chenopodium murale growing in saline soil of Pindara (EC 11.47 dS m-1), district Jind (Haryana). The nitrogen fixing ability of the isolate was confirmed by nifH gene amplification and acetylene reduction as...

Many species belonging to family Fabaceae are able establish symbiotic relationships with nitrogen-fixing bacteria. Studies developed Dalbergia ecastaphyllum (L.) Taub., for example, have demonstrated the potential of this species. In sense, study aimed analyze phenotypic characteristics rhizobia isolated from D. and identify whether these bacterial isolates capable establishing Vigna unguicula...
