This study was conducted to compare forage quality of two native halophytespecies Camphorosma monspeliaca and Limonium iranicum collected from Meighansaline rangelands near Arak city in center of Iran. Edible biomass of both species wassampled on three phonological stages (vegetative growth, full flowering and seedripening). Forage quality indices such as Crude Protein (CP), Dry Matter Digestib...
Single and dual crop coefficient methods are used in conjunction with grass reference evapotranspiration (ETo) to estimate actual crop evapotranspiration (ETc). However, the impact of soil surface residue cover on the accuracy of ETc estimated with these methods is not well understood. The objective of this study is to evaluate and compare the accuracy of the FAO-56 single crop coefficient (sin...
BACKGROUND An extensive retrospective study spanning several seasons was undertaken to evaluate the diagnostic performance of the BD rapid influenza diagnostic test (RIDT) in comparison with the RT-PCR assay. METHODS A total of 2,179 respiratory samples were tested in parallel by in-house RT-PCR and the RIDT. During the 2003-2004, 2006-2007, 2007-2008, and 2008-2009 (n=1671) seasons, the BD D...
