Influence of nitrogen timing on winter wheat grain yield and evaluation of nutrient management on the stratification of soil parameters in no-till
(2021-12)
Visual symptoms of nitrogen (N) deficiency is common in winter wheat fields. Whether it is due to unavailability of suitable application equipment or unfavorable application conditions, the crop may go a significant period ...
Agronomic and Economic Response of Hard Red Winter Wheat to Multiple Liming and Fertilization Strategies
(Oklahoma State University, 2012-12-01)
Application of agricultural lime is the most frequently recommended method for managing low soil pH; however, in-furrow phosphorus (P) fertilizer or pelletized lime are also commonly used to ameliorate soil acidity. The ...
Tolerance of Winter Canola (Brassica napus) Cultivars to Selected Residual Herbicides
(Oklahoma State University, 2010-05-01)
Winter canola planting continues to increase in Oklahoma and the Southern Great Plains due to the need for a winter broadleaf crop to rotate with winter wheat in order to expand weed control options. ALS-inhibiting herbicides ...
Winter Crop Rotation with Herbicides to Control Feral Rye (Secale cereale) and Italian Ryegrass (Lolium perenne SSP. Multiflorum)
(Oklahoma State University, 2010-05-01)
Limited control options and herbicide resistance have increased feral rye and Italian ryegrass infestations in winter wheat production in Oklahoma. A rotation with winter canola would increase control options. Field ...
Effect of topdress N rate applied based on growing degree days on winter wheat (Triticum aestivum L.) grain yield
(2019-12)
The majority of in-season nutrient management decisions for numerous crops are based on subjective morphological scales. The objective of this study was to establish whether a numerical scale based on growing degree-days ...
Effects of Intraguild Predation of Lysiphlebus Testaceipes by Chrysoperla Rufilabris Larvae
(Oklahoma State University, 2012-07-01)
Winter wheat (Triticum aestivum L.) is a major commodity grown in the Southern Great Plains. The most common and destructive pest in winter wheat is the greenbug (Schizaphis graminum Rondani). Fortunately, the greenbug has ...
Mapping of quantitative traits important to dual-purpose management of winter wheat
(2009-12)
Scope and Method of Study:
Influence of dual top-dress nitrogen applications on winter wheat (Triticum aestivum L.) grain yield
(2021-05)
Winter wheat (Triticum aestivum) is commonly grown throughout Oklahoma and is notably the state's top cash crop. Nitrogen (N) is one of the most heavily applied nutrients in wheat by producers across the state as it is ...
Enhancing Sustainable Cropping Systems Through the Use of Cover Crops
(Oklahoma State University, 2010-12-01)
An on-going experiment was established in Lahoma, OK to evaluate intensified cropping system and determine the possibility of including selected cover crops in rotation as well as evaluation of the use of GreenSeekerTM ...
Improving the drought risk assessment and preparedness for winter wheat farming in Oklahoma
(2022-07)
Droughts pose a persistent threat to agriculture in the Southern Great Plains (SGP). Oklahoma is a major contributor to dryland winter wheat farming in the SGP, acrop that is highly susceptible to drought episodes. Modern ...
