to study the mixing rates effects of barley (hordeum vulgare l.) and chickpea (desi type) (cicer ariethinum l.) on forage production under dryland conditions, a field experiment was conducted at agricultural research station of university of tehran (karaj campus) during the 2003 – 2004 growing season. the 11 treatments of this experiment were statistically compared based on a randomized complet...

Gibberella zeae, a causal agent of Fusarium head blight (FHB) in wheat and barley, is one of the most economically harmful pathogens of cereals in the United States. In recent years, the known host range of G. zeae has also expanded to noncereal crops. However, there is a lack of information on the population genetic structure of G. zeae associated with noncereal crops and across wheat cultivar...

Fusarium head blight (FHB), primarily caused by Gibberella zeae (anamorph1⁄4Fusarium graminearum), is a devastating disease that causes extensive yield and quality losses to wheat and barley throughout the world. Antagonists that suppressed FHB in earlier greenhouse studies were tested in a series of field experiments at different geographical locations in the United States in 1998–2000. In mos...

Background: Silicon (Si) can directly or indirectly enhance plant resistance to fungal pathogens, but no report is available concerning the effectiveness of Si in decreasing Fusarium Head Blight (FHB) disease on barley ( Hordeum vulgare L.). Objective and Methods: The evaluation supplied incorporated into soil as a foliar spray against four FHB species under controlled conditions was investigat...
