Effect of Nitrogen on Rhizobacteria Associated with Wheat Shoot Productivity
(Oklahoma State University, 2012-05-01)
The effect of nitrogen fertilizer on rhizobacteria associated with wheat (Triticum aestivum) shoot productivity was determined by using pyrosequencing technique. Easpur Loam soils was treated with 112-kg/ha N or left ...
World and United States Wheat Supply, Demand, Prices and a Pricing Model
(Oklahoma State University, 2010-07-01)
this thesis is composed of three studies. They will provide farmers, decision makers, and analysts information about wheat supply, demand, and prices. The first study, World's Wheat Supply, provides an overview about world's ...
Foliar Phosphorus Fertilization and the Effect of Surfactants on Winter Wheat (Triticum aestivum L.)
(Oklahoma State University, 2011-05-01)
Reactions of phosphorus fertilizer in soils make its use efficiency very low. The common application practices are to broadcast and incorporate or to band P with the seed. Foliar application of P can be used as a supplemental ...
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 ...
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 ...
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 ...
