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 ...
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 ...
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 ...

(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, ...
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 ...
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 ...
