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...

Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...

1. Children aged 6-35 months in an urban community in The Gambia, West Africa, were weighed and their lengths measured at four surveys over an 18-month period, twice towards the end of the rains, and twice during the dry season. 2. Relative to international standards, height-for-age deteriorated steadily with age, while weight-for-age fell sharply in the second-half of infancy but showed no fur...

Chickpea (Cicer arietinum L.), an important leguminous crop has a dwindling croparea everyday due to climate change, and the overall yield declined. In controlled conditionexperiment, four distinct levels of drought were applied ten different varieties chickpeas in petridish using polyethylene glycol (PEG) @ 0, 10, 20, 30%. As differentiating factors, germinationrate, plumule, radicle lengths u...

dodder is an obligate parasite of many plant families and among dodder species cuscuta campestris has the most diverse around the world. extensive infestation to dodder recently has been reported in some sugerbeet production regions of khorasan provinces. so, in this study greenhouse and field experiments were conducted to test and charachterize the tolerance of commercial sugarbeet varieties t...

this research was conducted in order to evaluate genetic diversity, and screening the tolerant genotypes of sugar beet subjected to continuous and severe water stress in the experimental farm of sugar beet seed institute (sbsi) in karaj in 2008. the experimental design was a randomized complete block with 6 replications. fifteen o-types which were tolerant to drought plus 5 (check) genotypes we...

the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to wa...

physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 mp) was studied on seed germination and plumule as well as radicule growth length in three species namely: agropyron elongatum, agropyron desertourm and secale montanum. polyethylene glycol (peg) was used to provide appropriate water potentials. a total of 100 seeds in four replications (petri dishes) were so...

The present study was carried out to assess the effect of leaf and bark aqueous extract of Anogeissus latifolia tree on Vigna unguiculata traditional crop to understand the suitability of treecrop combination in agricultural fields. Different concentrations of leaf (1%, 3% and 5%) and bark (1%, 3% and 5%) aqueous extract of A. latifolia were used to study radicle and plumule growth of V. unguic...

BACKGROUND Although the cardiac biomarker B-type natriuretic peptide (BNP) is strongly related to mortality in end-stage renal disease (ESRD), whether it is a predictor of weight change or blood pressure (BP) response upon probing dry weight among hypertensive hemodialysis patients remains unknown. The purpose of this study was to examine among people with hypertension on hemodialysis whether B...
