high intensity evaporation from the soil surface due to low air humidity and poor soil structure and organic matter are constraints of agriculture in arid and semi-arid regions of iran. regionally, maintaining plant residue with tillage management is one method to improve these conditions. in this study, for a barley-corn rotation, four barley residue management methods for standing stubble (bu...

This experiment was conducted to evaluate effects of different sources of natural pigments on yolk color and laying hen performance. A completely randomized design with six treatments and six replicates was used.The six experimental treatments were: a control diet containing yellow corn grain, a reference diet containing wheat and barley grain instead of corn; a red pepper diet composed of refe...

The University of Idaho provides equal opportunity in education and employment on the basis of race, color, religion, national origin, age, disability, or status as a Vietnam-era veteran, as required by state and federal laws. 1 Malting barley is the most valued variety of barley. However, growing conditions for malt-ing barley may result in a substandard quality that is unsuitable for use by t...

Root segments of vetch, barley, and pine were exposed to a nutrient solution containing (85)Sr and (45)Ca tracers. Translocation was measured from solutions containing stable ions at concentrations of 2.5 mm Ca, and at either 0.5 mm or 2.5 mm Sr. Polar transport was established between 12 and 18 hr in barley, and between 16 and 22 hr in vetch. Acropetal transport remained below 5% of basipetal ...

  Introduction: Celiac disease (CD) is a hereditary disorder of the immune system which damages the mucosa of the small intestine caused by gluten consumption(even very small amounts). Villous atrophy, leads to malabsorption, which is due to decreased absorption levels. The first bowel symptoms are seen during the first 2 years of life. Currently, the only treatment is to compliance with a glut...

the effect of feeding barley-based diets (%60) supplemented with four commercial enzymes containing xylanase and ?-glucanase activities were investigated on performance and gastrointestinal size of broiler chicks. the enzyme supplemented diets were compared with unsupplemented barley- or corn-based diets. a total of 234-day-old male broiler chicks (ross 308) were allocated to 6 treatment groups...

to evaluate the sensitivity of different crops included some pulses to simulated metribuzin soil residues, an experiment was conducted in completely randomized design with factorial arrangement and four replications in research greenhouse of college of agriculture, ferdowsi university of mashhad. treatments included of 8 crops (chickpea, common bean, lentil, corn, wheat, barley, rape seed and s...

BACKGROUND In a biorefinery producing cellulosic biofuels, biomass pretreatment will significantly influence the efficacy of enzymatic hydrolysis and microbial fermentation. Comparison of different biomass pretreatment techniques by studying the impact of pretreatment on downstream operations at industrially relevant conditions and performing comprehensive mass balances will help focus attentio...

during the last few decades cereals yield have increased drastically at the national level however, information about yield stability and its resistance to annual environmental variability are scare. in this study long term stability of grin yield of wheat, barley, rice, corn and overall cereals in iran were evaluated during a 40-year period (1971-2011). stability analysis was conducted using t...
