In situ degradabilities were determined for some commonly used grains and by-product feeds in dairy cattle rations. Ingredients evaluated were barley, shelled corn, soybean meal, brewers dried grains, corn gluten feed, distillers dried grains, soybean hulls, and wheat middlings. In situ studies were conducted in three rumen-fistulated Holstein cows. Cows were fed a total mixed Ž . rations conta...

This study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. About 4.5 kg urea and 1.5 kg salt were dissolved in 40 L water and mixed with 30 L of whey. The solution was spread over 100 kg chopped wheat straw. Thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...

A greenhouse study was conducted to investigate the effects of nitrogen (N) on wild barley (Hordeum spontaneum Koch) interference with winter wheat (Triticum aestivum var. Pishtaz) by an additive series experiment. The experiment was conducted in a split plot design with 3 replications. Wheat plant height losses were on average 30, 10, and 10% in a wild barley density of 16 plants per pot with ...

the sunn pest, eurygaster integriceps puton, is a serious pest of wheat in coraim region of ardabil province. in this study, the egg parasitoids of sunn pest was collected and identified in this region during 2007 and 2008. also, the percentage of egg parasitism was determined in 14 different defined areas in this region. the areas 1-3 were selected in irrigated wheat fields in the presence of ...

low cereal and legumes yields and their rwp index are mainly due to poor distribution of rainfall and poor agronomic management practices. rainfed barley yield and rain water productivity (rwp, defined as rainfed grain yield divided by the total crop season annual rainfall water) in the dry farming are considerable by topography and latitude. yield data, rainfall, altitude and latitude of 182 p...

The main goal of this study was to investigate the genetic basis of yield and grain quality traits in winter wheat genotypes using association mapping approach, and identify linked molecular markers for marker assisted selection. A total of 120 elite facultative/winter wheat genotypes were evaluated for yield, quality and other agronomic traits under rain-fed and irrigated conditions for two ye...

Himalaya 292 (Hordeum vulgare, var. himalaya 292) is a novel, hull-less barley cultivar with a single nucleotide change in the gene encoding starch synthase IIa (EC 2.4.1.21). This leads to loss of enzyme activity, resulting in a grain with less total starch and a higher proportion of amylose. These changes, plus higher total and soluble nonstarch polysaccharides (NSP), could increase its resis...

Salt tolerance of plants depends on HKT transporters (High-affinity K(+) Transporter), which mediate Na(+)-specific transport or Na(+)-K(+) co-transport. Gene sequences closely related to rice HKT genes were isolated from hexaploid bread wheat (Triticum aestivum) or barley (Hordeum vulgare) for genomic DNA southern hybridization analysis. HKT gene sequences were mapped on chromosomal arms of wh...
