Plants engineer the rhizosphere to their advantage by secreting various nutrients and secondary metabolites. Coupling transcriptomic and metabolomic analyses of the pea (Pisum sativum) rhizosphere, a suite of bioreporters has been developed in Rhizobium leguminosarum bv viciae strain 3841, and these detect metabolites secreted by roots in space and time. Fourteen bacterial lux fusion bioreporte...

Experiments were conducted to determine the ability of citrate to enhance the plant uptake of weathered 2,2-bis(p-chlorophenyl)1,1-dichloroethylene (p,p'-DDE) from soil. Plots containing three rows of clover, mustard, hairy vetch, or rye grass were constructed in soils containing p,p'-DDE. On 11 occasions, the rows of each crop received water or sodium citrate (0.005 or 0.05 M). For each crop, ...

this experiment contained four vetch lines (vicia panonica ) that conducted in two locations (faruj and bojnourd) in 2005-2006 in rcbd design with four replications under dryland conditions. analysis of variance indicated that there were significant differences among lines in different locations about all traits, except 100-seed weight. the interaction of genotype×location was significant on al...

Understanding ecophysiological characteristics of corn (Zea mays L.) under winter cover crops (WCCs) can improve management and farmers’ acceptance by increasing the positive effects and decreasing the negative effects associated with their use. This study was conducted to quantify the effects of WCC on corn development, growth, and yield through the evaluation of ecophysiological characteristi...

Objective: This study has been conducted in order to determine the effect of cumin essential oil on fermentation quality, aerobic stability, vitro metabolic energy contents and relative feed value vetch-oat silages. Material Methods: Vetch oat were harvested May wilted for approximately 3 hours. Cumin was added silages at CMN2:200 mg/kg, CMN3:300 mg/kg CMN5:500 levels, while no addition made co...

line wb73-6 (trompillo, cmb74a-432-25b-1y-ib-1y-ob) was first introduced in iran through a nursery received from cimmyt in 1989. it was selected in a preliminary experiment in zabol research station among the genotypes of ibon in 1990. in other preliminary and advanced yield trails carried out in zabol and other stations in southern provinces of iran with warm climate in 1991-1997, line wb73-6 ...

white been line wa8592-1 was first introduced in iran through the yield trail nurseries received fron ciat in 1991. in observation nurseries carried out during 1992 and 1993 cropping seasons, ten bean populations were evaluated for yield and other characteristics, and 60 lines were selected. preliminary and advanced yield trails carried out for six years (1995-2000) in four locations khomein, e...

an experiment was conducted in the experimental field of seed and plant improvement institute in karaj for three consecutive cropping seasons, 2001-2003, to study the effects of eight different fertilizer treatments including some microelements on grain yield and protein content of a bread wheat cultivar pishtaz. the experiment was in a rcbd with three replications.eight fertilizer treatments w...
