Potential of Hulless Winter Barley as an Improved Feed Crop
… conducted to determine the potential of hulless winter barley (Hordeum vulgare L.) as an improved feed crop in the mid-Atlantic region. Winter barley is an excellent crop in rotation with soybean (Glycine max L.); however, production of winter barley during the past few years has decreased mainly …

Intensive spring nitrogen management of winter barley: silage and grain yield and composition
… nitrogen application on yield and composition of barley forage and grain and the fermentation and utilization of barley silage was investigated in a 3-yr study. The use of a growth regulator, ethephon, was also investigated. Nitrogen application at a rate of 135 kg/ha increased forage yields in …

The effects of flame cultivation on the growth and nitrogen utilization of winter barley
… using the Calor Gas flame cultivator.<br/>Winter barley was sown in the 1986/87 and 1987/88 seasons using a range of seed bed preparation techniques at three nitrogen levels in a sandy loam to sandy clay loam soil in a 2 x 3 x 3 factorial experiment. Trials looked at stubble removal, crop …

Quantitative Trait Loci for Resistance to Fusarium Head Blight in the Hulless Winter Barley Cultivar Eve
… is a devastating fungal disease that affects barley production worldwide through damaged kernels, low yields, and production of mycotoxins. The most effective means of control is through the use of FHB resistant cultivars that are developed through gene pyramiding and incorporation of various …

Characterization of Hulled and Hulless Winter Barley, Hordeum vulgare L., Through Traditional Breeding and Molecular Techniques
… genotypic characterization of hulled and hulless winter barley (Hordeum vulgare L.) is necessary for improvement using traditional and molecular breeding techniques. Identification of genomic regions conferring resistance to Fusarium head blight (caused by Fusarium graminearum), leaf rust (caused …

Development of intensive nitrogen management strategies for winter barley (Hordeum vulgare L) in the mid-Atlantic region
Winter barley (Hordeum vulgare L.) production in the mid-Atlantic region occupies a substantial amount of arable land. Variable levels of winter and spring precipitation can result in N loss. The objectives of this study were to determine the optimum rate and timing of N fertilization and develop …

Investigation of winter wheat sowing date management and genetic architecture of malting quality in winter barley and milling/baking performance in soft red winter wheat
Wheat (Triticum aestivum, L) and barley (Hordeum vulgare) are widely grown as winter annual grains in a double crop rotation with soybean (Glycine max, L. Merr.) in much of the U.S. Improved management strategies and the development cultivars that meet the quality requirements of higher value …

Seedling emergence and growth of winter barley as affected by sowing date and sowing depth: a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours in the University of Canterbury
Establishment and growth of winter barley, c.v. "Illia", was compared at five sowing dates (22 April, 2, 14 and 30 May and 20 June) and two nominal sowing depths (20 mm and 50 mm) at Lincoln, Canterbury. Seedling emergence rate, total emergence and canopy development (number of leaves on the main …

Winter Barley as a Commodity Cover Crop in the Mid-Atlantic Coastal Plain and Evaluation of Soft Red Winter Wheat Nitrogen Use Efficiency by Genotype, and its Prediction of Nitrogen Use Efficiency through Canopy Spectral Reflectance in the Eastern US
… and 3) Cover N (no N application) effects on winter barley (Hordeum vulgare L.) plant biomass (PB), plant N uptake (PNU), grain yield, residual soil nitrate (RSN), and ammonium (RSA). In general, at winter dormancy, SIM resulted in increased PB and PNU but not RSN or RSA. At cover crop …

The role of genotypic diversity in stabilizing plant productivity in variable environments
… A. thaliana, were translated into the crop plant winter barley in field experiments. Mixtures achieved high and stable yields despite being subjected to multiple abiotic and biotic stresses, some of which were not anticipated. Unexpectedly, facilitation was identified as an important ecological …

Maximising the benefits of cover crops through optimising the use of rotations, nitrogen fertiliser and organic manures
… This involves growing species of plants over winter on land that would otherwise be left fallow. Cover crops sequester nutrients, protect soil from the elements through mitigation of excess rainfall, enhance crop diversity and can positively impact soil health. This project investigates if the …

BIOCHAR AMENDMENT TO IMPROVE SOIL PRODUCTIVITY WITH PARTICULAR EMPHASIS ON THE INFLUENCE OF SOIL TYPE
… contrasting soils in one field, cropped with winter barley (Hordeum vulgare), biochar (at 0, 50 t ha–1 & 100 t ha–1) had a range of predominantly positive effects. There were no significant increases in crop yield in this well managed agroecosystem, but variables which responded significantly …

The Genetic Architecture of Grain Quality and its Temporal Relationship with Growth and Development in Winter Malting Barley (Hordeum vulgare)
… of malting quality within the Virginia Tech barley breeding program, and discusses implications for imposing selection on complex traits that are difficult to phenotype. Malting quality measures are destructive, and can not be performed before selection must be made for advancement of …

Genetic Characterization and Linkage Mapping of Barley Net Blotch Resistance Genes
… is one of the most devastating diseases of barley (<i>Hordeum vulgare</i> L.) and occurs in two distinct forms, net-type net blotch (NTNB) and spot-type net blotch (STNB), caused by the fungal pathogens <i>Pyrenophora teres</i> f. sp. <i>teres</i> Smedeg. and <i>P</i>. <i>teres</i> f. sp. …

Contribution à l'étude de la relation parasitaire entre Typhula incarnata Lasch ex Fr. et l'orge d'hiver (Hordeum vulgare L. var. hybernum VIB.)
Typhula incarnata est une minuscule clavaire psychrophile qui peut être pathogène sur un grand nombre de graminées aux faibles et moyennes latitudes. Dans les décennies 1970 et 1980, ce champignon a connu en Belgique un grand développement dans les cultures d'orge d'hiver où il a souvent été …
