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 ...
Evaluation of management strategies for continuous forage production in central Oklahoma
(2021-12)
Forage production in the southern Great Plains is an important aspect of the agricultural industry because forage is used to feed livestock that produce many agricultural products that are consumed. A goal of agricultural ...
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 ...
Genome-wide analysis of drought stress induced histone 3 lysine 4 and histone 3 lysine 27 trimethylation modifications in winter wheat
(2020-07)
Drought stress brings great impact on plant growth and development, that it is the most critical threat to world food security. Although drought responsive mechanisms plants have developed to tolerate drought stress are ...
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, ...
Indirect response to yield selection for end-use quality and wheat-sensitivity indicators in hard winter wheat (Triticum aestivum L.) across six breeding cycles and three lineages
(2019-12)
A rising global population necessitates continued genetic improvement of wheat (Triticum aestivum L.), but not without oversight of intended and untended consequences along the way. This oversight is partly to blame for ...
