Nitrogen Cycling from Fall Applications of Biosolids to Winter Small Grains
… limit the amount of biosolids applied to winter small grains in Virginia. Ten field studies were established 2012-2014 in Virginia to determine the agronomic and environmental feasibility of fall biosolids applications to soft red winter wheat (Triticum aestivum L.). Eight studies were located in …

Investigation of Methods and Mechanisms of Control of Italian Ryegrass (Lolium multiflorum) in Corn (Zea mays) and Small Grains and of the Effects of Johnsongrass (Sorghum halepense) Control on Virus Diseases in Glyphosate-Tolerant Corn
Field experiments were conducted in Virginia to evaluate the efficacy of AEF-130060 03 plus AEF-107892 applied postemergence (POST) for the control of Italian ryegrass [Lolium multiflorum (Lam)] in barley [Hordeum vulgare (L.)] in comparison to other herbicides currently registered for use in wheat …

Molecular analysis of gene expression in oat plants that are tolerant or sensitive to barley yellow dwarf viruses infection
… important and widespread virus disease of small grains. Breeding resistant plants has been the most effective and economical method of control. In order to understand the molecular basis for tolerance to BYDV, studies were initiated to characterize the genes involved in the tolerance.

Pronghorn Use of Agriculture Land in Northwestern South Dakota
… monthly from June 1989 to July 1990 on alfalfa, small grains, native grasslands, and native sagebrush-grasslands to better understand influences of nutrient availability on habitat selection of pronghorns. Cropland, Conservation Reserve Program lands (CRP), and native prairie made up 17%, 4%, and …

An evaluation of production and marketing strategies for eastern Virginia cash grain producers
… of February. The acreages of com, soybeans, and small grains were specified based on soil type, government program participation, sales at harvest, storage, pre-harvest hedging, and post-harvest hedging. The expected farm plans for the 1987 crop year resulted in participation in the government …

Relationship of selected parameters to farm sale values in three Virginia counties
… Crop yield ratings for forages, soybeans, and small grains were found to be significantly related to sale price in the case of the Piedmont farms. Yield ratings for small grains were also found to be significantly related to sale price in the case of the Coastal Plain soils. Indices of soil …

Relay- and double-crop production systems for wheat
… system is common with legumes seeded into small grains; however, the companion crops may compete for water, nutrients, and sunlight, which may slow development of either crop. Relay-intercropped soybean [Glycine max (L.) Merr.] production involves seeding wheat in the fall and an intercrop …

Soil nitrogen, active carbon, corn, and small grain response to manure injection
… N was not limiting at the other seven sites. A small-scale research plot study examining fall manure applications under small grains found similar results to the previous study. No consistent differences in soil NO3-N were observed between injected, broadcast, and control plots; however, soil …

Quantitative Trait Loci for Resistance to Fusarium Head Blight in the Hulless Winter Barley Cultivar Eve
… Eve has been identified in Virginia Tech's Small Grains Breeding Program. The objectives of this study are to validate resistance and identify additional resistance QTL, and identify tightly linked and diagnostic markers for use in MAS programs. A population of F5:7 RILs derived from the …

Summer and Fall Ecology of Gray Patridge in Eastern South Dakota
… in 1979. Radio-tagged partridge primarily used small grain gields during brood rearing (22 June – 21 August). Small grain may have offered more adequate cover than other agricultural crops. During the late summer and early fall (22 August – 21 October) partridge shifted to standing row crops …

A Genome Wide Association Study for Fusarium Head Blight Resistance in Southern Soft Red Winter Wheat
<p>Fusarium head blight (FHB) is a disease of small grains caused by the fungal pathogen Fusarium graminearum. FHB poses potential economic losses and health risks due to the accumulation of the mycotoxin deoxynivalenol (DON) on infected seed heads. The objectives of this study are: 1) evaluate …

Effects of Maturity at Harvest of Triticale and Dietary Forage Inclusion on Production Performance, Nutrient Utilization, and Milk Fatty Acid Profile of Lactating Dairy Cows
The objective of this study was to evaluate the impact of maturity at harvest and dietary inclusion rate of triticale silage on the production performance and nutrient utilization of lactating dairy cows. The hypothesis was that the production performance of lactating dairy cows would increase when …

Lattice thermal conductivity of bulk and polycrystalline PbTe from computer simulations
… case concentrations are more limited. However, small grains are not stable at high and intermediate temperatures, so in the second part of the thesis we study if grain boundaries survive or not against thermal coarsening under operational conditions. We attacked this problem by means of a …
