Relationship Between Coefficient of Variation Measured by Spectral Reflectance and Plant Density at Early Growth Stages
(Oklahoma State University, 2004-12-01)
Nitrogen use efficiency (NUE) is estimated to be 33% throughout the world, current precision nitrogen application through precision sensing methods can improve NUE to a level of 50%. Statistical analysis of sensor data has ...
Economics of Wheat and Canola Cropping Systems For Oklahoma
(Oklahoma State University, 2005-12-01)
Hard red winter wheat in Oklahoma has not been very profitable. Winter canola varieties have been developed. A crop rotation may enable producers to better manage weeds and diseases, increase yields, and increase net ...
Feasibiltiy of a Wheat Marketing Center in Oklahoma
(Oklahoma State University, 2004-05-01)
The purpose of this study was to determine the feasibility of operating a non-profit, hard red winter wheat marketing center in Oklahoma. To determine if there was a need for a marketing center, total world wheat exports, ...
Rapid Phenotypic Assessment of Bird Cherry-oat Aphid Tolerance in Winter Wheat
(Oklahoma State University, 2004-07-01)
Rhopalosiphum padi L., or the bird cherry-oat aphid, causes significant damage to winter wheat (Triticum aestivum L.) in the Great Plains. Our objective was to develop a juvenile-plant bioassay for BCO tolerance that allows ...
Explaining Differencesin Prices Received by Farmers: Testing Theory Based on Actual Farmer Transactions
(Oklahoma State University, 2004-12-01)
Years of research have been dedicated to determining the best time for producers to sell their commodities. Researchers have developed basis models, market efficiency tests, hedging/risk models, price forecasting models, ...
Winter Wheat Cropping and Tillage Systems
(Oklahoma State University, 2004-05-01)
In the southern Great Plains, wheat is a multiple use crop. It may be produced either for grain-only, forage-only, or as a dual-purpose crop for both forage and grain. Research was conducted to determine the most economical ...
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 ...
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 ...
Mapping quantitative trait loci for agronomic and quality factors in wheat
(2005-05)
Scope and Methods of Study: Agronomic and quality traits are important factors in wheat (Triticum aestivum L.) improvement and in determining end-use product value. Knowledge regarding the number, genomic location, and ...
