genotypic variation is useful to breeders when selecting genotypes to improve particular traits. inorder to study of genetic diversity 20 genotypes of hordeum murynum studied in the form of randomized complete block design the experimental field of islamic azad university shahre rey branch with 3 replication in the year 2012. notes traits was conducted including days to heading, days to maturit...

The influence of application of increasing doses of selenium (0.05 mg, 0.10 mg and 0.20 mg/kg) into soil in pot experiments, with NPK fertilization of spring wheat (Triticum aestivum L., variety Banti), on the biomass yield (grain, straw, roots) and on selenium accumulation was observed. Selenium in the form of sodium selenite (Na2SeO3·5H2O) and the NPK nutrients in the form of LAD-27, Ca(H2PO4...

an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...

Demand for food security and the current global warming situation make high and strict demands on the North China Plain for both food production and the inhibition of agricultural carbon emissions. To explore the most effective way to decrease soil CO2 emissions and maintain high grain yield, studies were conducted during the 2012 and 2013 summer maize growing seasons to assess the effects of w...

A pot experiment was conducted at six graded levels of copper (Cu) viz., 0, 0.5, 1.0, 1.5, 2.0 and 2.5 mg kg(-1) to test the response of wheat plants grown in a copper-responsive alluvial soil (entisol) under glass house conditions. The growth attributes like plant height, fresh and dry matter yield, percent dry matter enhanced with increasing Cu levels and was maximum at 1.5 mg kg(-1) Cu while...

To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...

the objective of this study was to investigate the effects of addition of pulses in crop sequences, crop residue management, and application of fertilizer n on soil nitrogen content, soil organic carbon, nutrient uptake, and its consequences for wheat yields. the field experiments were carried out from 2009 to 2012 in the sub-humid and sub-tropical zone of northern india. the treatments were (i...

Four beef steers (avg wt 300 kg) fitted with duodenal re-entrant cannulae were used to study the effect of dietary concentrate to forage ratio on bacterial and nonbacterial N flow in the duodenum. According to a change-over design, the steers were designated to receive an all forage (83% alfalfa hay and 17% wheat straw) and an 80% sorghum grain diet. Lignin (ADL) and chromium oxide (Cr2O3) rati...

                The present study was undertaken to evaluate direct and indirect selection criteria for the improvement of grain yield and quality components in Chenopodium quinoa Willd. Correlated response (CR) and relative selection efficiency (RSE) were estimated for grain yield and three quality components, grain protein, grain carotenoid and leaf carotenoid based on different contributing ...
