applying a suitable tillage method is vital to chickpea production in dryland conditions. hence, eight tillage methods were studied using strip plots in a randomized complete block design with three replications over three years at the dryland agricultural research institute in maragheh, iran. the amount of rainfall in the three years of the study were 202, 264 and 203 mm, respectively, which w...

Understanding the relationship between sink and source in maize is of prime importance in maize growing regions. In this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the College of Agriculture, Shiraz University, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of  SC704 maize hybrid.  A fa...

in order to study the effects of drought stress and nitrogen (n) levels on grain yield, yield components and water use efficiency of grain corn (sc.704), a field experiment was conducted in 2009 growing season. the experiment was split-plot based on randomized complete block design arrangement and four replicates. main plots were three irrigation levels included optimum irrigation (i1), moderat...

the objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (dm yield) and 5 quality traits such as dry matter digestibility (dmd%), water soluble carbohydrates (wsc%), crude protein (cp%), acid detergent fibre (adf%) and total ash in tall wheatgrass (agropyron elongatum). in th...

Twenty-four lactating Holstein dairy cows were used in a completely randomized design to investigate the effect of soybean meal (SM) and xylose protected soybean meal (XSM) in combination with ground (GB) or steam flaked (FB) barley on dry matter intake, milk production, rumen fermentation and blood responses. The experimental period lasted for 30 days. The diets consisted of the provision of 1...

Cadmium (Cd) is one of the most toxic non-essential and mobile metallic elements found in soils which affects plant growth. A greenhouse experiment was carried out to determine the genotypic differences in effects of different levels of Cd application on yield and on the uptake of Cd and other nutrients in various Brassica plant parts. The B. juncea (Indian mustard) genotypes produced higher bi...

The Department of Defense and Department of Homeland Security use many threat detection systems, such as air cargo screeners and counter-improvised-explosive-device systems. Threat detection systems that perform well during testing are not always well received by the system operators, however. Some systems may frequently “cry wolf,” generating false alarms when true threats are not present. As ...

This paper is concerned with reconstruction theories of which-questions, and shows that one major limitation of these approaches lies in the way these theories derive de dicto readings of sentences such as Mary knows which children cried. Specifically, we show that when a wide range of de dicto facts is considered, an analysis where wh-phrases never reconstruct must be preferred over the recons...
