the effect of soil and topographic features on distribution of amygdalus scoparia in nehbandan (iran) was investigated. slope, aspect and altitudinal maps were overlaid to prepare a working map unit. quantitative and qualitative traits, including height, number, collar diameter of sprout with the highest diameter, crown diameter and trunk health were recorded in 1000 m2 plots (27 plots). in eac...

abstract background: nutrients meeting recommended dietary intakes take time to establish and once established are rarely maintained throughout hospital stay in preterm infants. methods: our purpose is to define the nutritional status and growth parameters of hospitalized patients at discharge in our hospital. data were obtained concerning all 50 infants born weighing < 1800 g and < 34 weeks of...

in this study, population dynamics of venerid bivalve paphia cor was investigated for a one-year period (2008-2009) in bushehr shoreline areas (50˚ 40´ e- 29˚ 14´n) to estimate the stock abundance, growth parameters and natural mortality. sampling was carried out bi-monthly by transects at random direction and zigzag pattern with duplicated quadrate (0.25 m2). the length frequency was used to e...

the life table parameters of schizaphis graminum (rondani) (hemiptera: aphididae) on four commercial cultivars of wheat (kohdasht, pastor, tajan and zagros) were determined in laboratory conditions. fertility life table were constructed using age-specific survivorship (lx) and age-specific fecundity (mx) and subsequently analyzed using jackknife method and anova. there were significant differen...

this study was conducted with different levels (0, 0.25, 0.5,1,2 g) of zingiber officinale powder per 100 g of common carp commercial diet. feed was offered for 8 weeks by the post pelleting liquid spraying method. results showed that there were significant differences in all growth parameters and body composition except in survival rate, gain weight percent (gw%) ,sgr and nfe between treatment...

in order to investigate the effect of plant growth promoting rhizobacteria (pgpr) along with zinc (zn) and manganese (mn), foliar spraying on the morphological parameters of basil (ocimum basilicum l.) an experiment was conducted in factorial based on a randomized complete block design with three replications in 2011. treatments were the pgpr inoculation with azotobacter and azospirillum (azb+a...

peppermint (mentha piperita l.) is one of the most important plants producing essential oil. an experiment was carried out using a randomized complete block design with 3 replications to study the effect of salinity stress on growth parameters, essential oil percent of peppermint. 4 levels of salinity solution containing 0, 50, 100 and 200 mmol nacl was applied in irrigation plantings in a gree...

the data were collected from 1992 to 2009 in burri, white boni and black boni sheep maintained at the regional research station in the central highlands of yemen. data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. the least square means for body weights (bw) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...

the life table parameters of macrosiphum rosae l. (hemiptera: aphididae) on five vermicompost-tea (tea-compost) concentrations (20, 40, 60, 80 and 100%) and control treatment (0%) on rosa hybrida l. were determined under laboratory conditions. there were significant differences among pre-imaginal period and adult longevity of the aphid on the five teacompost concentrations. the highest mortalit...
