to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...

Barley can be cultivated and gives better yields in a large number of environments under various fertilization practices. This experiment was conducted two growing seasons 2018/2019 2019/2020 rainfall condition. Four new introduced cultivars barley (Arta, Tadmor, Clipper Furat2) along with commonly grown (Local-1 Local-2) were represented the current study; Soil (DAP) foliar treatments also inv...

Limited information is available on control of broadleaf weeds in barley and response of barley cultivars to herbicides. Field experiments were conducted from 2007 to 2009 to evaluate post-emergence herbicides for control of broadleaf weeds in four barley cultivars. Herbicide treatments included 2,4-D sodium salt at 500 g ai ha 1, carfentrazone-ethyl at three rates (15, 20 and 25 g ai ha 1), an...

A 7-year study located in Prince Edward Island, Canada, examined the influence of compost and manure on crop yield and nematode populations. The compost used in this study consisted of cull waste potatoes, sawdust, and beef manure in a 3:3:1 ratio, respectively. No plant-parasitic nematodes were detected in samples collected from windrow compost piles at 5- and 30-cm depths prior to application...

Stripe rust of barley, caused by Puccinia striiformis f. sp. hordei (PSH), occurred mainly in California, Idaho, Oregon, and Washington and caused localized damage to barley crops. Growing cultivars with high-temperature, adult-plant resistance and the cropping system contributed to the low level of stripe rust. Stripe rust samples were collected from the four states and tested under controlled...

the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...
