Fate of amended phosphorus and sorption of ciprofloxacin in soils
(2020-07)
Environmental contamination from natural and anthropological sources is receiving increased attention due to risks to human and ecological health. Manure from concentrated animal feeding operations is generally applied to ...
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 ...
Winter wheat varietal tolerance to Metribuzin tank-mixed with pyroxasulfone
(2021-12)
Metribuzin is a herbicide that is widely used in cropping systems. However, its use in winter wheat in Oklahoma has declined due to varietal sensitivity or lack of information regarding the topic. To evaluate modern wheat ...
Evaluating plant density in grain sorghum using GreenSeeker
(2021-05)
Grain Sorghum (Sorghum bicolor(L)Moench,) is a high yielding, drought tolerant crop commonly grown in Oklahoma and the southern Great Plains. Increased knowledge of agronomic production practices, such as planting densities, ...
Soil nitrogen storage and mineralization potential in a winter wheat system under long-term nitrogen fertilization
(2022-05)
In winter wheat systems, crop nitrogen(N) uptake is sourced primarily from inorganic N fertilization and N mineralization from soil organic matter(SOM). N mineralization is a dynamic N cycling process that relies on many ...
Implementing new alfalfa technologies into water-limited environments
(2021-12)
Oklahoma is predicted to experience a shift in rainfall patterns and experience prolonged droughts in future years. With a changing environment, producers will search for new technologies to mitigate forage losses in this ...
Cotton growth stage specific irrigation and fiber quality response in the Great Plains region
(2022-12)
With decreasing water availability and increasing cotton (Gossypium hirsutum L.) production in the Great Plains region, a more efficient irrigation schedule and variety response needs to be assessed to make production more ...
Effect of the method and rate of planter applied nitrogen on corn and grain sorghum production
(2023-05)
In Oklahoma corn (Zea mays) and grain sorghum (Sorghum bicolor L) account for nearly 20% of all the total value of farmed cropland in the state. Fertilizer, specifically nitrogen (N) is one of the greatest input cost and ...
Integrated management of Bromus Species in grain only winter wheat production of the southern Great Plains
(2021-11)
Bromus spp. including rescuegrass, cheat, and downy brome are difficult to manage winter annual grass weeds in southern Great Plains winter wheat. Producers can manage Bromus spp. in herbicide-tolerant wheat, but control ...
