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 ...
Starter Fertilizer Management for Corn and Soybean in the Southern Plains
(Oklahoma State University, 2012-12-01)
Early plant growth and grain yield may be depressed in no-till cropping systems compared to conventional tillage because of the poor nutrient availability early in the growing season. Oklahoma no-till corn (Zea mays L.) ...
Maize (Zea-maize L.) Grain Yield Respond to Nitrogen Applied at Different Distances Away from the Row
(Oklahoma State University, 2010-05-01)
A one percent global increase in nitrogen use efficiency would be worth approximately 1 billion dollars (Raun and Johnson, 1999). It is thus important to apply nitrogen (N) midseason or split applied so as to improve ...
Geologic Controls on Nitrogen Isotopes in Marine Black Shale: a Case Study of the Woodford Shale, Anadarko Basin, Oklahoma
(Oklahoma State University, 2013-12-01)
Determining depositional environments of organic-rich black shale can enhance the identification of hydrocarbon producing intervals. Several methods have been utilized to identify depositional environments; however, for ...
Controls on Bud Activation and Tiller Initiation in Tallgrass Prairie: the Effect of Light and Nitrogen
(Oklahoma State University, 2010-12-01)
Chapter 1: Perennial grass populations in tallgrass prairie ecosystems are maintained primarily through vegetative outgrowth from their belowground bud banks. Resources in these ecosystems that have been found to limit ...
Long-term Prescribed Fire Does Not Alter Litter Decomposition and Bioavailable Nitrogen in Xeric Oak Forests
(Oklahoma State University, 2013-12-01)
The Cross Timbers is a patchwork of grassland, savanna, and xeric oak forest that stretch across Kansas, Oklahoma, and Texas. Historically a pyric ecosystem, burning of the Cross Timbers became infrequent. Currently, land ...
By-plant Sidedress Nitrogen in Corn (Zea Mays L.) Based on Plant Height and Normalized Difference Vegetation Index
(Oklahoma State University, 2012-07-01)
Current methods of applying nitrogen (N) fertilizer do not treat small scale variability that is known to exist. Variations in corn grain yield can be found from one plant to the next. With knowledge that yield potential ...
