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 ...
Determination of Nitrogen Availability From Animal Manure Amended Soils
(Oklahoma State University, 2007-07-01)
This study was conducted to evaluate the effects of long term manure application on soil properties, winter wheat, grain yield, and to determine the N availability of land applied manure. Three different manure sources and ...
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 ...
