Use of near Infrared Reflectance Spectroscopy for the Characterization of Wheat and Barley Grain Entering Feedlots in Western Canada
(Oklahoma State University, 2014-05-01)
The first experiment evaluated the use of near infrared reflectance spectroscopy (NIRS) for the nutrient prediction of wheat grain and the factors affecting in vitro dry matter digestibility (IVDMD) and in vitro kinetics ...
Mid-season Recovery to Nitrogen Stress in Winter Wheat
(Oklahoma State University, 2004-12-01)
Winter wheat yields are directly affected by the amount of nitrogen (N) that is available to them for growth. Past research has indicated that spring application of N is more effective than fall application for winter ...
Hessian Fly Seasonal Flight in Oklahoma's Wheat Growing Regions
(Oklahoma State University, 2014-07-01)
Wheat is the most economically important food crop grown in Oklahoma. The Hessian fly is a common pest in wheat in all of the wheat production zones of North America. The Hessian fly was first recorded coming into the ...
Fitness, virulence and genetic variability in Pyrenophora tritici-repentis isolates causing tan spot of wheat in Oklahoma
(2010-05)
Scope and Method of Study: Isolates of Pyrenophora tritici-repentis (causal fungus of tan spot of wheat) collected from the 1980s, 1990s and 2000s were studied for their fitness, virulence and genetic relationship. Mycelial ...
Analysis of the coefficient of variation of remote sensor readings in winter wheat, and development of a sensor based mid-season n recommendation for cotton
(2008-05)
Scope and Method of Study: For chapter one, Hard red winter wheat (Triticum aestivum L.) experiments were conducted to better understand how the coefficient of variation (CV) could be used to better mid-season N rate ...
Improvement in Genetic Yield Potential of Semi-dwarf Wheat in the Great Plains of the USA
(Oklahoma State University, 2011-12-01)
Recently, private companies and public entities have made significant investments in and improvements to their wheat (Triticum aestivum L.) breeding programs. Because of this increased interest, recent genetic improvements ...
How Much Would It Be worth to Know the Wasde Report in Advance?
(Oklahoma State University, 2013-12-01)
Past research has shown that prices move in response to WASDE reports, but have only looked at price movements immediately prior to and after a report. This research seeks to determine the profitability of trading based ...
Effect of Simulated Grazing Intensity on Dual Purpose Winter Wheat (Triticum Aestivum L.) Grain Yield in Oklahoma
(Oklahoma State University, 2011-12-01)
Dual-purpose winter wheat growth and grain yield are influenced by cattle stocking density and variety selection. The objectives of this study were to determine the effect of mowing height on winter wheat grain yield, ...
Effects of Plant Population and Nitrogen Rate on Spectral Properties and Grain Yield of Winter Wheat (Triticum aestivum L.)
(Oklahoma State University, 2011-07-01)
Predicted grain yields enable producers to more accurately apply the needed top-dress nitrogen (N) which leads to improved N use efficiencies and increased profit. This study was implemented to correlate and determine the ...
No-till Versus Tilled Dryland Cotton, Grain Sorghum, and Wheat, and Breakeven Pasture Lease Rate for Dual-purpose Winter Wheat
(Oklahoma State University, 2011-12-01)
This study consisted of two papers. The research reported in the first paper was conducted to determine the optimal tillage and cropping system among three crops and two tillage systems. Yield data for cotton, grain sorghum, ...
