The effect of weeds, plant diseases and insect pests on spring barley (Hordeum vulgare) wheat (Triticum aestivum) grain nutrient yield was examined. Long-term field trial data used to assess the impact different yield. In absence pesticides, fungal caused largest annual yield-reduction in barley, 500 kg ha?1 average. Converting loss this represented reductions 8.1 9.2 nitrogen 1.5 1.6 phosphoru...

Despite the global value of barley, compared to its wild progenitor, genetic variation in this crop has been drastically reduced due to the process of domestication, selection and improvement. In the medium term, this will negatively impact both the vulnerability and yield stability of barley against biotic and abiotic stresses under climate change. Returning to the crop wild relatives (CWR) as...

some parts of semitropical regions in khouzestan, fars, kohgiloyieh-va-boyrahmad, lorestan, golestan, ardabil, kermanshah and boushehr provinces specified to spring barley cultivation which local or a few improved cultivars are grown there. barley breeding activities in dryland agricultural research institute(dari) are continuously undertaken in gachsaran, kouhdasht, gonbad and moghan to introd...

The biotrophic rust fungi Puccinia hordei and Puccinia striiformis are important barley pathogens with the potential to cause high yield losses through an epidemic spread. The identification of QTL conferring resistance to these pathogens is the basis for targeted breeding approaches aiming to improve stripe rust and leaf rust resistance of modern cultivars. Exploiting the allelic richness of w...

comparison of energy productivity of different crops can be used as an effective tool to prioritize crops planting in each area. this study was conducted in order to compare of wheat and barley farms of sistan and blochestan province in relation of various aspects of energy consumption at 2009. 100 wheat and 100 barley fields were selected randomly from zahedan, zabol, saravan, khash, iranshahr...

khorram was primarily received as an introduction barley for low rainfall area- cold winter (lra-cw) with the pedigree of sfa02/3/rm1508/pro//w12269/4/hml-02 arabiabiad//er/apmicb92-0926-0ap-2ap-0ap from international center for agricultural research in the dry areas in the 2002-2003 cropping season. khorram cultivar was tested in the preliminary, advance yield trial and uniform regional yield ...

introduction barely (hordeum vulgare) is the fourth most important cereal after wheat, corn and rice. regarding the role of breeding to increase barley grain yield a large number of studies have been done in different countries. however, a few studies have been performed across golestan province, in iran. therefore, this study was conducted to know what barley traits have changed with grain yie...
